Important Information

• To avoid the unnecessary replacement of multiple PC boards, please read this before beginning to repair this unit.

• Do not use any service documentation other than the one designed for this particular model.

• Techniques used on previous models may not necessarily apply to the model you are working on.

• For accurate diagnosis during troubleshooting, do not skip or alter the order of steps on the guide.

Slide 2

When an abnormality occurs in the unit, the “SOS Detect” circuit is triggered and the TV shuts down.The power LED on the front panel will flash a pattern indicating the circuit that has failed.

Cautions:

If the power LED continues to blink even after the TV is unplugged, press and hold the power switch on the TV for a few seconds until the LED turns off.

Some steps require removal of connectors and sometimes PC boards removal. Do not allow the TV to run for more than 30 seconds while connectors or boards are disconnected.

NOTE: When taking voltage reading, place your meter’s probe on the test point or pin indicated before connecting the TV to the AC line. The voltage you intent to measure may only appear for a brief moment.

Warning: The Vsus line has large capacitors that hold the charge for some time even after the TV has been turned off and unplugged. When disconnecting P2/SC2 or P11/SS11, bleed the remaining charge of the Vsus before reconnecting the cable.

Use a 500 ohms/ 5W (At least) resistor to discharge the Vsus line before reconnecting P2/SC2 or P11/SS11.

Troubleshooting No Power/Dead Unit (Power LED is Off) (TC-P**S60)

Start Here

Make sure the connectors on the P board are properly seated. Unplug the TV and disconnect connector A6(55/60/65inch) / A6A(42/50inch) on the A board. Measure the resistance between chassis ground and pin 10(STB5V) and pin 5(F15V) of connector A6 / pin 22(STB5V) and pin 3(F15V) of connector A6A on the A board. (See the picture below for connectors’ location.)

Sustain Drive：All the lines are same waveform.All the lines are connected mutually.

SS board doesn't cause horizontal lines problems. All the electrodes on SS board are common.

If horizontal line is showed, it is possible that defect of one pin of scan drive IC or failure of connection to the panel or damage of electrode on the panel.

When FFC is damaged, it is needed to replace the panel The FFC is bonded to the panel directly.
