Hi,
I have just replaced led set of this vestel tv due to age.
I would like to reduce backlight from service mode. I have tried menu 4725 but in the menu i can't change anything.


Any help pls? I don't want to change from electronics inverter feedback resistor ideally.
Thanks again....

Thanks for the manual and the hint.

I have managed to repair the power supply by replacing the IC U9101 SSC3S927

Am trying to find a pdf .

i have no secondary output voltage. So far done the obvious checked supply on primary caps 320v, supply on power supply ic found 22v and cannot see any burnt components.
tried with meter most components like resistors diodes etc.
in secondary there are no shorts either.
This was struck by a lightning and could see a burn under the air gap capacitor.

Attaching the board.
Any clues welcome.
Tks...
