Egy eltérítő tekercset keresek ebbe a készülékbe.A tipusa:DIF -2192 DA.Másik Samu tekerccsel probálkozon,de nem oké a színtisztaság és a konvergencia.
Üdv.,ferenc.
Kedves Kollégák!
Lassan föladom /magam:)/. Villámos a tárgy. Szeptemberi.
Táp ok. Tda 8844 döglött volt, néhány mp alatt tűzforró lett.
Csere után a nagyfesz ciccen egyet, majd leáll a vezérlés.
Táp nem áll le. Processzor /SAA5297/ csere után is ua. a helyzet.
Képeltérítő LA7845. Hang TDA9859.
Kérdésem igazán az lenne, hogy lehetne a védelmet megkerülni?
Samsungnál kardinális kérdés. Gondolom a proc. lekérdezi a perifériákat és csak utána engedélyezi az indítást.
Köszönöm, üdv, kovácsa
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 !

Tisztelt Kollégák!
Szívok ezzel a mocsokkal.
Karácsony előtt cseréltem sortranzisztort, körbe volt repedve sormeghajtó trafó ill. a stabtáp ícék lábai.Ment egy hétig újból tranyó hibás lett, ekkor kollektorköri kondik csere.
Ma négy hónap után visszajött. Tele van a púpom vele :-(
Nincs ötlete valakinek, mi okozza?
Köszi, üdv, kovácsa
