Good luck... Most manufacturers do not release either any more.

Your service manual will be your "eyes and a meter"... plus what ever guidance you get from here after you do some investigation of the set.

If you would like help you will need to:
Post good clear straight on pictures of back of tv with cover off and each board.


Need voltages from connector that goes from power supply board to main board. Will need pin#- PIN DESCRIPTION -Pin voltage in standby-Pin voltage when pushing power button and picture of connector on power supply board.
Format:
Pin# - Pin Description - Pin Voltage standby - Pin voltage power on
1 - XXXXXXX - XXv - XXXv
2 - XXXXXXX - XXXv - XXXv
3 - XXXXXXX - XXXv - XXXv
4 - etc.

Okay, here is what I see on CN201:
Pin 15 - No TCON on
Pin 14 - No 12v TCON
Pin 9 - Yes 12v
Pin 8 - Yes 12v
Pin 4 - No 12v Audio
Pin 3 - 5v PS ON (stays at 5v)
Pin 2 - 3.5v AC DET

CN 301
All 24v lines are active

These readings are after set is plugged in, no control of on/off function.
Is this bad PWR supply or Main board?

Can we see good clear pictures of the connectors and the labels? Also need good clear straight shot pictures of the top and bottom side of the board.
Which version of the boards do you have?
