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.
