TOSHIBA 65l945VQ Backlight problem
Trying to fix a Semi-Working TV I got for free.
There is a picture, but the backlight is ON only in one-quarter of the screen:
*The screen after disassembly
For a brief period when turning on the TV, all LEDs flicker fast for about 1s period.
then just one quarter remains lit.
I couldn’t find anything obviously wrong with the LED control board
no bulging CAPS or something obviously burned.
power supply lines to that board from the main PSU (8 lines of 24V) all seem to work.
I’ve unplugged and plugged all relevant connectors
Any advice on what can be wrong…
