Hello everyone,
i am new to the forum and i would like to save a TV from the dumpster. I figured out that IC207 is broken on the mainboard of this TV. Does anyone have a schematic for these kind of TVs or even have the same and knows what IC this is? I presume it is a voltage regulator. The TV is totally fine but does not turn on any more. The power supply is perfectly fine. I desoldered this IC as it was getting very hot and was the only issue i found.
Thank you!!!

Hello,
I have a problem with my Samsung TV.
Error description:
The power supply unit clicks when I switch it on. Background lighting comes on for about 1 second and then goes off again.
Everything has been checked:
LED strips from the lighting are ok. have removed and tested them.
I have already replaced many electrolytic capacitors with new ones.
Disconnected the mainboard flex cable. same error.
Disconnected both plugs for the background lighting.
nothing has changed.
I can't find a suitable circuit diagram either
Power supply unit: BN44-00633B
PLEASE HELP.
