Hi guys,
Ok, so I just picked up this TV which, at first glance looks like it has no picture, but upon unconnecting one of the two cables providing display to the screen, you can tell the back-light for one side of the screen lights up.
I checked all the voltages on connector CNM803 on the PS board and they all checked out good for what they should read according to the board. They are listed below:
I then checked the surface mounted fuse on the T-Conn board which I believe is FP1 and it has 12.9V running through it.
Possible main board issue? Any ideas on what I should check? Thanks!

- PWM_DIM - 13V
- B13V - 13V
- BLU_ON/OFF - 13V
- GND
- GND
- A5V - 5.2V
- POWER ON/OFF - 5.2V
