Samsung TV UE55F7090 clicks permanently
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.

Samsung UE55MU6502U nem ad életjelet!
Sziasztok.

Adott a címben szereplő tv. A történet röviden: A hosszabbító-amiből ez is csatlakoztatva van- be lett csukva az erkélyajtóba. A tv pattant egyet, de a lakásba is elment az áram. Zárlat! Az áram vissza kapcsolása után a tv nem ad életjelet, de minden más működik. A kábele jó, kimértem. Szóval ezen a tv-n hátul egyetlen csavart sem találtam. 4 kis fület láttam alul, de azok kipattintása után is tartott még valami. Szóval...hogyan kell szétszedni ezt a tv-t? Ha tudnátok segíteni azért hálás lennék. Youtube-on, nem találtam ilyen videót.

Köszönöm.

Üdv.

Sziasztok! A stby LED először 6-ot, majd 7-et villog. Kaptam hozzá doksit, de sajnos nincs benne a hibakód tábla. Találkozott már valaki ilyennel ?
