XBR-75X940D array backlight works but LCD panel shows no picture
With a video input, I can see the array backlight move with the picture, but the LCD screen itself is black. Even on-screen menus don’t appear - the LCD is not functional.
ANSWERS:
"Hi @hikeonpast
The service manual (your model number seen on p.2) seems to indicate that the cable to the tcon board, the mainboard or the panel itself may be the problem
Here’s the no picture troubleshooting flowchart from the service manual which may help.
Having no audio also seems to put it back to the mainboard as it is not just a problem with the video section of the TV"
