IntroductionThe DLP field Service Guide is a reference manual comprised of parts lists,interconnect drawings, flow charts, troubleshooting processes, and generalinformation about DLP sets. It covers all versions of DLP up to the time of publication.The DLP chassis covered by this manual are:

• ATC311M

• ATC322

• ATC323

• ATC332

• ATC336

• ATC351

• ATC352

Use of this manual to troubleshoot DLP sets is the main purpose. By using thegeneric flow charts found in this manual (page 30), the servicing technician canisolate a specific circuit area and then use the chassis / series / DM module specifictroubleshooting procedures, also found in this manual, to further verify the suspectedcircuit. The flow charts alone won’t condemn a component but give strong suspicionto a component. Further troubleshooting is required to verify exactly where theproblem is.

The troubleshooting procedures for each circuit / device are designed to verify whatis working or not working in that circuit / device. Each troubleshooting procedureassumes that other circuit / device of the set have been eliminated and the circuit /device for that procedure need further isolation. Troubleshooting procedures are inthree areas:

• AC IN

• DM Module

• Light Engine

These procedures are categorized by chassis for the AC IN, DM module type for DMModule and series for the Light engine. Each of these sections provides a briefdescription to aid technicians in identifying the circuit, module, or light engine theymay be working on.

A major parts list and fast moving parts list are provided for reference only. The majorparts list is sorted by model number and covers only major parts found in DLPs. Thefast moving parts list is what was selling the most at the time of publication.

The Appendix is made up of general information about DLPs. It includes TechnicianNotes, GIS (General Information Series) and Bulletins.

ATC311 AC IN CBA OverviewThe standby and main (run) power supplies are located on the AC In circuit board.A voltage multiplier is also located on the AC In CBA. This multiplier produces thevoltage required by the ballast lamp power supply. A relay is used to control AC tothe doubler circuit. This relay is operated by routing the +12VS voltage through thelamp door switch. This switch is a safety feature that shuts off the relay shutting downthe ballast supply when the lamp door is opened.

The outputs of the standby supply includes +/- 21V for the Audio circuit board, +6VS,+5VS, -5VS, +12VS and +33VS to the DM2CR. A power fail (PwrFail) signal isgenerated by the standby supply and is routed to the DM2CR. PwrFail signal is anearly warning for the DM2CR to perform emergency shutdown procedures.

The main (run) supply provides the +5VR and the +12VR that is required by the A/V In/Out circuit board. The +9VR, +12VR, +5VR and the Power_Good signal aregenerated by the run supply. The Power_Good signal informs the light engine (viathe formatter CBA) that all run voltages are nominal. This signal goes low if the runsupply turns off. This allows the light engine to perform pre-shutdown functions. Therun supply is turned on via the On/Off signal from the DM2CR (via connector J24605-13).

ATC311 AC IN TroubleshootingSetup: Place AC IN in the service position.

Main Fuse Open Troubleshooting1. Check the main fuse (F24201). If open, measure across the main B+ for a

short. If no short, replace fuse and apply AC power.

2. Fuse opens again, suspect secondary load problem or AC IN.

3. If fuse is ok, see if set will start. If set won’t start continue with Run PowerSupply Troubleshooting.

Note: Measurements on AC IN connectors are done with the connector attached atthe AC IN for safety reasons. For isolated measurements with connector removed,leave connector attached at the AC IN and disconnect the other end.

Standby Power Supply Troubleshooting1. Apply AC power and check connector J24604 for correct voltages per chart.

Voltages correct go to next step. Voltages missing disconnect J13604 andretest. Voltages return suspect DM2CR module.

2. Check connector J24605 for correct voltages per chart. Voltages correct, goto next step. Voltages missing disconnect J13602 and retest. Voltagesreturn, DM2CR is suspect. Voltage missing, suspect AC IN CBA.

ATC322/323 ACIN CBA OverviewThe ACIN CBA (circuit board assembly) of the ATC32x chassis consists of a standbysupply to power the DM3 module, run supply to power the AVIO and Light Engine,unregulated Raw B+ for subwoofer supply, and an unregulated supply to drive theLamp Ballast supply. These voltages are either regulated by the ACIN or regulatedfurther by the individual circuits they feed. The ACIN CBA produces the followingvoltages:

· +36Vdc

· +12Vdc

· +5Vdc

· -5Vdc

· +20Vdc

· -20Vdc

· Unregulated +151Vdc (RAW_B+)

· Lamp power supply B+ (300Vdc – 390Vdc)

There are two switched supplies (RUN) that are controlled by system control. Thesevoltages are +12Vdc SW and +5Vdc SW. Both are controlled by the RUN_EN fromthe DM3.

The principle of the standby and run supplies is a current-mode controlled, zerovoltage switching (ZVS) supply. The supply uses discrete control circuit and coldside regulation.

Raw B+ is developed when AC is applied to the set. DP201 bridge rectifier and twofilter caps convert the AC voltage too approximately +151Vdc unregulated. ThisRaw B+ feeds the standby supply and where applicable subwoofer circuits.

AC is also supplied to the voltage doubler circuit to develop the +300Vdc requiredby the Lamp Ballast supply. A lamp door switch and relay SP251 prevent the+300Vdc from being developed whenever the lamp door is open. This is a safetyfeature and should not be defeated except by qualified servicing technician.

A Power Fail signal is logically combined with the RUN_EN signal to form a POWERGOOD signal. This signal is sent to the DM3 where the system control determinesthe state of the power supply. This is also used for the “batten-down the hatches”routine commonly found in most Thomson TV products.

ATC332 / 336 AC IN OverviewThe AC IN provides both Standby and Run power to the Light Engine, Lamp Ballast,and DM3x module. It uses Zero Voltage Switching (ZVS) supply for Standby andRun with a voltage doubler for the Lamp Ballast supply. The voltage doubler is drivenfrom the Main B+ supply and activated by the Lamp Door Switch.

Voltages produced by the AC IN CBA are:

Standby:

• +320V Lamp Ballast

• +12V (DM3x)

• +6V (DM3x)

• +33V (DM3x)

• +5V (DM3x)

• -5V (DM3x)

• +15V (AC IN)

• -25 (AC IN)

Run:

• +3.3VDLP

• +12V

Most of the standby voltages go to the DM3x. The three that don’t go the DM3x arethe +320V Lamp Ballast and the +15V / -25V used by the AC IN. The run voltagesgo to the Light Engine and are controlled by the Run_Enable from the DM3x.

The AC In CBA of the ATC35x chassis is designed for the ADM3 decoder. Thissupply complies with the 2006 California legislation regarding standby power andEnergy Star. A dedicated standby supply is added using the Fairchild FSD210BGreen Mode Power Switch and the main supply uses an Energy Star compatibleswitching regulator.

The audio amplifier power comes from a single +12.6 supply capable of 2 times 10W output power at 10 % THD.

A +12.6 standby supply provides the majority of the power for the embedded systemwith the balance from the +6 volt supply. The +6 Volt supply is tapped from the samewinding as the +12.6 standby supply to insure good regulation independent of loadchanges.

The third supply provided by the main switcher is the +12.6 V DLP supply for the lightengine. This supply is switchable for turn-off during standby mode to meet EnergyStar requirements. An AC line doubler is used to provide power to the lamp ballast.

DM2CR Module OverviewThe DM2CR module has 2 RF inputs labeled ANTENNA A and B. Antenna A is inputto a Tuner/IF module that contains a tuner section and dual IF section. The tuneris capable of processing both digital and analog RF signals (ATSC & NTSC) fromeither terrestrial or cable sources. The tuner is a single conversion, electronicallyaligned tuner with improved cross-modulation, UHF image rejection, and localoscillator phase noise performance over previous tuners. Performance is tailoredto handle the predicted signal environment during transition to digital terrestrialtelevision (HDTV) service, 256QAM digital cable, as well as providing “cable ready”NTSC performance as specified by the FCC. Antenna B input is the PIP tuner andis NTSC only.

The DM2CR has 2 DTV Link connectors which are compressed digital video inputs/ outputs offering an IEEE-1394 type video connection for consumer devices suchas satellite receivers, cable receivers, and digital recorders that meet the specificationsfor DTV Link. DTV Link is better known as 1394 or FireWire for digital televisions.Audio and video information is carried on a single wire in a two way configurationallowing playback and record capibilities.

The DM2CR module contains a GPIP IC (U23501) and performs the following:• NTSC processing• ATSC decoding• Process YPrPb• Process S-Video• Decode Y+C• Adaptive combing of composite video• Performs PIP function (Analog on Analog only)• Recover Teletext, closed caption and Gemstar data• Digitize all 1H video inputs• Outputs digitized YPrPb

TL851 is a video decoder, display processor with scan rate converter. For 1H videoinputs, the output will be up-converted to 2H 480p and the display will be locked tothe incoming video. The TL851 recovers HDTV video signals in YPrPb format fromdigital bit streams output from the VSB (visidual side band) decoder and processesthem for display. The HD output is analog (YPrPb), and can be 1080i, for HD inputs(1080i, 1080p, or 720p) or 1920x480p for SD (standard definition) inputs. The TL851also generates the text and graphics for the OSD (on-screen display). The TL851outputs two types of video, Analog SD video (2H NTSC), Analog ATSC video(YPrPb) along with the appropriate audio. The HD video output provided to theformatter consists of YPrPb, Horizontal and Vertical sync signals. These analogsignals are converted by the formatter into the digital Low Voltage Differential Signals(LVDS) needed to drive the Light Engine.

Page 67: Philips DLP_FieldServiceGuide_SCB Training Manual

Page 67

Formatter Module OverviewThe formatter circuit board is required for converting the analog video from either theDM2CR or analog inputs from the A/V In/Out circuit board into a format that iscompatible with the light engine. DC power for the formatter circuit board and thelight engine is supplied by the main (run) power supply located on the AC In CBA.These supplies include +5VR, +12VR, +3.3VR and +2.5VR. A Pwr_Good from therun supply is routed through the formatter CBA. This +5Vdc signal tells the lightengine that supplies are at nominal value and when the supplies are not, the signalgoes low.

All functions and circuits on the formatter circuit board are monitored and controlledby the system control microcomputer in the DM2CR. This is accomplished via theRUN 2 I2C clock and data lines. The Run 2 bus I2C bus is routed through the formatterboard to the light engine.

DM3 Module OverviewThe DM3 is the next generation of control, signal processing and signal receptioncircuitry contained in a single module. There are provisions for ATSC, NTSC andQAM RF reception. QAM provides the capabity to receive Cable "In the Clear"and with a "POD" (supplied by the cable provider), will also display encryptedsignals depending on the consumers program package. It will also upconvertNTSC RF or baseband video and perform all audio processing from the varioussources including AC3, Dolby Digital and XT True Stereo.

With minor modifications the DM3 will drive the 3 series of DLP light engines ora PTV chassis, replacing the onboard formatting IC for DLP with a digitalconvergence microprocessor for PTV.

The DM3 contains all previous DM2CR features adding:

Digital Cable Ready Tuning (DCR)Single scan frequency (PTV: 2.14H, DLP 3H)HDMI input (replacing DVI-HDCP)Wired remote control (Wired IR)

The DM3, although contained entirely on one PCB, requires a power supply andan AV IO board to form a complete signal processing and control system. Thefollowing diagrams show the different DM3 configuration required for the threeinstruments it will drive.

Figure 1

Page 71: Philips DLP_FieldServiceGuide_SCB Training Manual

Page 71

Figure 3; ATC323 (Slim DLP)

Figure 2; ATC322 (Classic DLP)

The DM3 does upconversion of NTSC RF, baseband and component video andalso accepts component inputs that may be 2H, 2.14H or 3H. All signals areconverted to one output format for DLP, (3H, 720P). When necessary and for thepurposes of discussion these three scan rates, 2H (31.469KHz), 2.14H (33.67KHz)and 3H (45KHz) will be used to designate the horizontal scan rates.

DM3X Module OverviewThe DM3x is a redesigned DM3 in a larger package that includes:

Digital Cable Ready Tuning (DCR)HDMI outputIntergrate I/O for Analog inputsSpeaker outputG-Link (Factory Service)

DTV Link, Ethernet conneciton and Wired Remote are removed on the DM3X.

The DM3X front end is comprised of two functional tuners, a single conversionterrestrial tuner (SCT) and a double conversion (DCT) cable tuner. The SCT tunermodule consists of a tuner and IF capable of receiving NTSC. The SCT has aseparate IF output for receiving digital (ATSC) and providing the Link chip with ATSC8-VSB or 64/256-QAM at the IF frequency.

The DCT tuner consists of a directional coupler and a cable tuner. The tap side hasa low pass filter for the Out-Of-Band (OOB) tuner. The cable tuner has an IF outputwhich is used for both NTSC and digital decoding purposes. The IF section of theFront End has switching capability for either the SCT or DCT tuner digital IF path. TheLink chip is responsible for digital demodulation and error correction of 8-VSB and64/256-QAM IF signals and for providing a serial transport stream to the DM3X backend for processing. The Link chip provides a local oscillator signal for the OOB tunerfront end and is responsible for OOB digital demodulation of a QPSK IF signal andfor providing a serial data stream to the POD module.

Series 3 Lamp Verification Process1. Remove the front cover and remove Lamp cartridge.2. Connect Jumper leads to terminal connector on Lamp as shown in the

photos and reinsert Lamp.

NOTE: A jumper wire cut in half works best for this connection. Strip off ¼” ofinsulation and solder the bare ends of jumper wire to make a “pin like” end forpushing into the terminal connector. Make sure connection is made by usingOhm meter to measure between the terminals and jumper wire. Make surejumper wires do not come in contact with any thing or anyone!

Warning: Be sure to route meter wires away from the lamp reflector /housing as the lamp creates extreme heat that will melt the wire insulation.

Note: Do not connect a multi-meter to the jumper wires if the lamp is not lit.Voltages up to 20KV are present when the initial lamp strike occurs.

3. Short out Lamp Door safety switch.4. Apply AC to the unit and press the power button.

a. If the lamp fails to light, go to GIS 05-001 for furthertroubleshooting.

b. If the lamp attempts to light, go to next step.

5. Connect the Multi-meter (in AC mode) to the jumper wires. The voltageshould be approximately +20vac when the lamp first strikes. (see Figure5)

6. After warm up (approx. 20 seconds) the AC voltage will stabilize between80vac to 120vac. (see Figure 6)

7. If the start-up or full run voltages climb to 121vac or higher, the lamp maybe close to the end of its life and replacement may be a consideration ifthe lamp is intermittent.

If the run voltages are lower than 120v, the lamp assembly should beconsidered operational.

Note: The lamp ballast monitors the lamp voltage and will shutdown thesupply if it meets or exceeds 125vac.

Series 4 Light Engine ID

The Series 4 light engine is a compact design for smaller cabinets. A majorchange from previous series is the light tunnel length which is greatly shortened.Lens size is reduced and the driver board is more compact. Three fans are usedon the series 4. One for the lamp, one for the driver / ballast and one for colorwheel housing.

The series 4 and 4.1 are identical except the series 4.1 uses a DVI inputconnector where the series 4 has HDMI. Minor change in mounting assemblydesign is all that separates these two.

DLP UHP Lamp / Lamp Ballast Characteristics

As with all troubleshooting, a good understanding of the circuit or process is needed. We willcover the fundamentals of Lamp Strike or Ignition, Lamp Lit (Burn), and Defective Lamp. Afterthe fundamentals have been covered we can begin to troubleshoot the Lamp and LampBallast.

Basic Lamp Construction:

In the DLP line up there are several different Lamp / Ballast venders. For each vender theLamp design is mated with the ballast design and the light engine that controls the ballast.These parts are NOT interchangeable between venders. When replacing a lamp or ballastalways refer to the service model with suffix to insure the correct part is ordered.

The basic construction of a Lamp consists of:

• Arc Tube

• Back Connector

• Reflector (Lamp Assembly)

• Lead Wire

• Side Connector

Arc Tube: This is where the arc takes place and is also known as the “burner”. Internal to thearc tube are two electrodes made of tungsten. Surrounding these electrodes is mercury vaporand other gasses. To generate the arc, the electrodes are supplied with high voltage. Oncethe arc has jumped the gap between the electrodes, current starts to flow and the lamp is lit.The operating pressure inside the Arc Tube is around 200 bar.

There are two connectors, Back Connector and Side Connector. These connectors provideelectrical connection between the Ballast Supply and the Arc Tube through the LampAssembly.

Reflector (Lamp Assembly): The reflector reflects the light generated by the Arc Tube into afocused beam used by the light engine.

Lamp Characteristics

The above graph shows the characteristics of a UHP lamp over its life cycle. As the lamp ages,the light output decreases with the erosion of the electrodes. Because of the erodingelectrodes, both the lamp operating voltage and number of strikes required to start a cold lampincreases. The number of strikes required to start a hot lamp also increases over time butstarts out slightly higher than cold strikes. A “HOT” strike is defined as striking a lamp that isabove room temperature.

There are several conditions that decrease or shorten the life of the lamp. A few are listed here:

• Heat (Improper Ventilation)

• Shock (moving unit while in operation)

• Fast paced cycling set on and off

Heat is by far the worst condition of them all. With out proper ventilation, the lamp life can bereduced by 75% or better. Thermo protection is used to shutdown the lamp if excessive heatis detected.

Lamp Strike (Ignition)

The voltage required to ignite the lamp varies by lamp manufacture. Also, the number ofignition cycles it takes to light the lamp may vary. As the lamp ages, more ignition cycles maybe required to start the lamp. Typically, the ignition voltage is from 5Kv to 20Kv.

When the lamp is hot it is more difficult to ignite then when cold. As the temperature increasesso does the pressure in the Arc Tube. With the higher pressure, the lamp may requireadditional strike times to get the Arc Tube to light.

When a lamp fails to strike there is an indication besides the obvious lack of light output. Ifthe lamp fails to strike the DLP front panel LED will blink a sequence (see service data or IBfor number of times power LED blinks for each model). In DM3 based models this will repeatfor up to 5 minutes after which time the power LED will start to flash rapidly for about 1 minute.The blinking of the power LED occurs after each failed attempt to strike the lamp. The LEDblinking sequence is not a replace lamp indicator, this only indicates that the lamp has failedto strike. A open lamp door will also cause the LED to blink in the same manner. Multiple strikefailures could indicate a defective lamp or lamp ballast supply.

Lamp Lit (Burn)Once the lamp starts to draw current, the voltage to the lamp drops significantly. This indicatesthe lamp is in the operating state. The typical voltage for operating is approximately 70-100VAC. This is measured between the lamp back and side connectors. As the lamp agesthis voltage will increase. When the voltage reaches approximately 125VAC, the ballastsupply will send information to the light engine indicating the lamp is defective. At that pointthe Light Engine will shutdown the ballast supply.

Defective LampAs the lamp ages two things happen. One is the number of strikes to start the lamp operatingincreases and the other is the lamp operating voltage increases. A lamp is considereddefective when it consistently takes more than three strikes to light the lamp or the lampoperating voltage exceeds approximately 125VAC. Depending on the set, some will strike thelamp indefinitely others will stop after 5 minutes. A defective lamp may never strike or takeseveral minutes to light. Another indication of a defective lamp is when the lamp lights andafter reaching full brightness it shuts off. A lamp nearing the end of life is verified by monitoring

Page 123: Philips DLP_FieldServiceGuide_SCB Training Manual

Page 123

the lamp run voltage. The lamp is considered defective if the run voltage is within a few voltsof 125VAC. NOTE: As the lamp lights and heats up the lamp run voltage climbs slightly.

WARNING: EYE DAMAGE MAY RESULT FROM DIRECTLY VIEWING THE LIGHTPRODUCED BY THE LAMP. ULTRAVIOLET RADIATION EYE PROTECTION IS REQUIREDDURING SERVICING.

Lamp Troubleshooting TipsLamp lights and shuts down:

• Thermo protection (poor ventilation)

• Lamp run voltage exceeding approximately 125V

Lamp intermittent or won’t light consistantly after 3 strikes:

• Remove Lamp assembly and check for loose connectors on lamp, tighten asneeded.

• If the lamp successfully lights, check lamp run voltage. If over 120VAC, suspectlamp.

• During strikes, is the spark gap on the ballast supply arcing and making noise?Yes, suspect lamp. No, see Ballast Supply Troubleshooting.

• Lamp door open or defective lamp door switch

Lamp Ballast Supply Troubleshooting Tips1. Check to make sure all supply voltages are present at the lamp ballast supply.

2. Remove Lamp assembly from instrument

3. Start set and monitor spark gap on ballast supply

4. Is the ballast supply spark gap arcing and making noise? Yes, suspect Lamp. No,suspect ballast supply.

NOTE: Measuring the lamp voltage during a strike will damage most meters. It is recommendedthat the lamp voltage only be measured when the lamp is lit.

Models: All DLP Models

Serial Number: All Serial numbers above D421XXXXX

TOPIC: Addition of lamp/ballast manufacturers

Symptom: Lamp will not strike or lamp shuts down intermittently

Cause: Incorrect lamp or ballast installed

Cure: Install the correct lamp or ballast

Lamps Design Background At this time, each manufacturer of UHP (Ultra High Pressure) lamps designs both the lamp and ballast as a package. This is due to each lamp type requiring a very specific combination of both strike/run voltages and frequency. Mixing of the lamp or ballast parts among lamp manufacturers may result in lamp striking issues, intermittent lamp shutdown and reduced lamp life. Due to current shortages of UHP lamps, new manufacturers of UHP lamp/ballasts have been introduced into all RCA and Scenium DLP products. Modifications to the DLP chassis have been made to accommodate the new lamp types. IMPORTANT -Any lamp and ballast replaced must match the original factory part. Lamps and ballasts cannot be interchanged between lamp manufacturers. When replacing a defective lamp or ballast, refer to the service model suffix and the appropriate service data to ensure correct parts replacement. As an additional reference, the lamp part number is printed on the lamp cartridge. DM2CR and Formatter The DM2CR (Stock # 263290) and Formatter module (Stock # 263247) have been updated to accommodate the addition of the new lamp manufacturers. The updated modules carry the same stock numbers as the original DM2CR and Formatter modules.

TOPIC: Identifying OSRAM Ballast Replacement Parts

Symptom: After replacing the ballast, various video artifacts such as excessive contouring, jagged edges or unstable/flashing brightness are apparent

There are several versions of OSRAM ballasts used in TTE DLP Televisions. Although these ballasts look physically identical, there are critical differences in each version. Each ballast version receives customized software in order to marry the ballast to the various engine types. These ballasts versions are not interchangeable. When replacing a DLP ballast, always refer to the latest service data to correctly identify the ballast. Use the below reference and the associated pictures to correctly match an OSRAM ballast to the proper stock number.

• Each ballast version has a 10 character “Identcode” placed on the 2D barcode sticker. This code can be used to cross reference the ballast to the correct stock number.

• In the case of the 381691XXXX and 507869XXXX, the “X” letter represents a wild card as there are several possibilities for the last 4 characters.

• Each ballast version has a ballast “type” label. This label can be used to easily identify the 273012 due to the blue “DB08” stamped on this label.

DATE: 9/5/2006

Chassis: ATC351A, ATC352A

TOPIC: Intermittent Actuator

Serial Number: Product built prior to G34XXXXXX

Symptom: Jagged edges in OSD and diamond pixels in video

Cause: Intermittent light engine actuator during the power on cycle

Cure: Remove LV196 from the ADM3 module

Background Some versions of DLP light engine design utilize digital micro mirrors in a diamond pattern instead of the traditional rectangular pattern. These engines use an optical actuator that shifts the light path by one half-pixel sideways on alternate frames. This allows the engine to reproduce all of the pixels in a high-definition image while using only half the number of micro mirrors. The DLP models listed below were produced with a highly intermittent light engine actuator. In these models, the actuator may intermittently fail to start when the DLP is turned on. Cycling the DLP on and off may or may not resolve the symptom. A defective or non-working actuator will result in a very distinct video artifact easily recognized by stair step edges on OSD text and small diamond shaped patterns across the entire video display. (Figure1)

Appendex D: Chassis Notes

ATC311 NOTES

Video rolling has tried 3 DM2 and it is that way out of monitor out jack.

Found the I/O board bad.

Chassis:ATC311

Lamp would either fail to strike or would shut down within 20 secs of lighting.Set may continue to cycle on and off, trying to strike the lamp each time. NoLED flashes.

Verified ballast voltages as normal during lamp strike/run. Checking pin 2 ofthe color wheel index connector showed normal pulses during start up butpulses would drop out as the color wheel came up to speed. Listeningcarefully to the color wheel as it spins up reveals that it is spinning too fastand it may sound as if it is hunting before the set shuts down.

Replace the color wheel asm.

The run on/off run supply is controlled by the DM2 module pulling the base ofQ24704 located on the AC in board low. This turn the photocoupler offallowing the oscillator to run.

To test: Ground the base of Q24704 to the respective ground.

Intermittantly would shut off lamp and color wheel. Still had audio.Power_Good line, j24702 pin 14 would go low. Replaced light engine pertech line. Still had problem. Green led would flash 5 times, then continouslyfor about 1 min, then stay green

Look at base of q24712, should be about -5v, was +0.6v.

Found CR24717 open, intermittantly.

Comments: looks like power-good line being held low by bad engine orformatter(?)
