2.3.2 Schematic Notes
All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm).
Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm).
All capacitor values are given in micro-farads (= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12).
Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).
An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.
The correct component values are listed in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.
2.3.3 Rework on BGA (Ball Grid Array) ICs
GeneralAlthough (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded.
Device RemovalAs is the case with any component that, it is essential when removing an (LF)BGA, the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the chance of warping the PWB.To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet.etal tools. er of a
rd to the depending waveforms hem in the lour bar
Area PreparationWhen the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has shown to result in problems during re-soldering.
Directions for Use EN 5LC4.6E AA 3.
Device ReplacementThe last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers.So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times.

tips will rise drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch off unused equipment or reduce heat.
Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If not to avoid, clean carefully the solder-joint from old tin and re-solder with new tin.
Use only original spare-parts listed in the Service-Manuals. Not listed standard material (commodities) has to be purchased at external companies.

delivered in so-called "dry-packaging" to protect the IC against moisture. This packaging may only be opened short before it is used (soldered). Otherwise the body of the IC gets "wet" inside and during the heating time the structure of the IC will be destroyed due to high (steam-)pressure inside the body. If the packaging was opened before usage, the IC has to be heated up for some hours (around 90C) for drying (think of ESD-protection!).Do not re-use BGAs at all!
For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method: Always use the highest temperature to solder, when using
SAC305 (see also instructions below). De-solder thoroughly (clean solder joints to avoid mix of
two alloys).Caution: For BGA-ICs, you must use the correct temperature-profile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions)You will find this and more technical information within the "Magazine", chapter "Workshop information".For additional questions please contact your local repair help desk.
2.3.5 Practical Service Precautions
It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.
Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions - reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

ComPair allows very detailed diagnostics (on I2Cis therefore capable of accurately indicating probYou do not have to know anything about I2C coyourself because ComPair takes care of this.
ComPair speeds up the repair time since it canautomatically communicate with the chassis (wmicroprocessor is working) and all repair informdirectly available. When ComPair is installed togthe Force/SearchMan electronic manual of the chassis, schematics and PWBs are only a mouaway.
5.4.2 Specifications
ComPair consists of a Windows based fault findingand an interface box between PC and the (defectiveThe ComPair interface box is connected to the PC (or RS232) cable. For this chassis, the ComPair interface box and thecommunicate via a bi-directional service cable via tconnector(s).
The ComPair fault finding program is able to determproblem of the defective television. ComPair can gadiagnostic information in two ways: Automatic (by communication with the television

ComPair to communicate (read and write) to devices on the I2C/UART buses of the TV-set.
Manually (by asking questions to you): Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extend. When this is not the case, ComPair will guide you through the fault finding tree by asking you questions (e.g. Does the e AUTO tter,

You can answer by clicking on a link (e.g. text or a waveform picture) that will bring you to the next step in the fault finding process.
By a combination of automatic diagnostics and an interactive question / answer procedure, ComPair will enable you to find most problems in a fast and effective way.
Beside fault finding, ComPair provides some additional features like: Up- or downloading of pre-sets. Managing of pre-set lists. Emulation of the (European) Dealer Service Tool (DST). If both ComPair and Force/SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink. Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Mono-carrier. Click on the Panel hyperlink to automatically show
the PWB with a highlighted capacitor C2568. Click on the Schematic hyperlink to automatically
show the position of the highlighted capacitor.

5.5 Error Codes
The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.
5.5.1 How To Read The Error Buffer
You can read the error buffer in 3 ways: On screen via the SAM (if you have

5.6 The Blinking LED Procedure
Using this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture.
When the SDM is entered, the front LED will blink the contents of the error-buffer: The LED blinks with as many pulses as the error code
number, followed by a time period of 1.5 seconds, in which the LED is off.
Then this sequence starts is repeated.
Any RC5 command terminates this sequence.
Example of error buffer: 12 9 6 0 0After entering SDM, the following occurs: 1 long blink of 5 seconds to start the sequence, 12 short blinks followed by a pause of 1.5 seconds, 9 short blinks followed by a pause of 1.5 seconds, 6 short blinks followed by a pause of 1.5 seconds, 1 long blink of 1.5 seconds to finish the sequence, The sequence starts again at 12 short blinks.
