SAMSUNG CK566BT
Jó napot mundenkinek! A sasszé típusa SCT57B. A probléma, hogy bekapcsoláskor a tv elindul, OSD van de se kép se hang.Egy pár perc után egyszerre megjön minden.A tápegység feszültségei szkóppal mérve nem brummosak.Mindenesetre tettem rájuk hátulról plussz kondenzátorokat, a kf proc mellett az összeset kicseréltem, a KA7630 és a KA7805 körül az összeset kicseréltem. A sorkimenő melletti elkókra tettem plusz kondenzátorokat.Nem változott semmi.Kontakt hiba nincs, mert már átforrasztottam mindent a text modul kivételével, de azt is kiveszem és átforrasztom. Egyetlen eltérés hogy a KA7805 power lábán amikor rossz 3,7V mérhető, mikor pedig jó 4,1V. A KA7630 4-es lábát ugyanez kapcsolja és ha a C831 10uf kondenzátorra 100uf-t tettem ,megjött rögtön minden.Így megy a tv ,bár még nem üzemeltettem.De ez nem gyári állapot.Mi lehet az oka? Kezdek kifogyni az ötletekből. Jól jönne egy kis segítség. dínó
SAMSUNG UE40D5000 power board no more working
Hi, my SAMSUNG UE40D5000 tv doesn' t work anymore. The red led light indicating that the tv is plugged is not powered when I plug in the tv. The original power board modem is BN44-00473B. I have checked the voltage on the connector to the mother board of the tv, and it was 0 instead of 5.3V or 13V on the different pins, with the fuse still working and no obvious overheated part on the power board and no bulging capacitor seen neither.
I have then changed the power board with a used one bought on ebay, which model BN44-00473A is said to be compatible. It has then worked perfectly 2 days until yesterday. This morning I had to move a little bit the tv, what I did very gently, and got really disappointed as I plugged it and didn't see the red led light on anymore.
Since this morning, the power board seems to be broken once more ( I have moved from my original flat 1 week ago and don't have a multimeter to check once more that the fuse is ok and what are the voltage on the connector to the mother board )
I am wondering if this new power board failure is just bad luck, 2 days after receiving this other power board circuit ( that is a used unit, not brand new) or if the mother board could have damaged it. In the first case I would send the power board back to the seller, otherwise I will probably give up as I don't have time and skills to repair the tv.
My question is : do you think the mother board or another unit connected to it, can damage the power board ?
Thanks for your help and answers !

Samsung cz-21f12z TV nem indul
Sziasztok! Samsung cz-21f12z típusú tv abszolút nem indul. 300 V ok, IC801S KA5Q0765RT 5. lábán tápfesz 9,8V. A primer oldali 33u és a táp ic cserélve, aktív és passzív elemek átmérve. Érdekes a készülék, mert a PC801S opto benne sincs a panelban. A szekunder oldalról semmi nem terheli zárlattal, a KA7632-t ugyan nem cseréltem, de a bemenetén nincs zárlat, és mondom mintha egyáltalán nem is próbálna éledni a táp, egy árva impulzust sem látok bekapcsoláskor. Ha valakinek van valami ötlete, szívesen veszem! Szép estét! Vonal
