Sziasztok! A fenti plazma időnként a mellékelt képet produkálja... Üdv: Wolf

Üdv mindenkinek! A fennt említett TV egy 16:9-es csővel szerelt gépezet. Működik, de a kép csak a közepén fókuszos, körben elmosódott. Raszter hibát nem látni, nem sortrafós. Tapasztalat nincs vele hibát nem találok. Segítségeteket kérném. Üdv.: Laci

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.

:help: Hi,this set will play tv or AV normal for few minutes and the video will disappear ,while the heaters are on and the eht normal and sound ok.all voltages are normal.I changed all eletrolitics caps on the B+ ,190v,12v,5v and 3v rails.This is an old set.now i suspect the x ray protection circuits ,but all seems well.But when no signal applied no aerial input the set dont loose video till it goes to standbye,telling that when much current is drawn (video or lopty current)is then that the fault happens.
