11ak30 függőleges eltérítés
Jó napot kívánok mindenkinek. Az lenne a gondom ezzel a tévével hogy nincs függ. eltérítés. Már két tévé van ugyanazzal a hibával az asztalon. Cseréltem a dzsungel és függ. icéket, de eredmény nincs. Az eltérítő tekercs nem szakadt, elkókat néztem, már nem tudom mihez nyúljak. A TDA hideg szerintem nincs meghajtva. Nem lehet ez valami típushiba? Valaki már küszködött hasonló problémával? Kérlek segítsetek. Üdv. mindenkinek.
Samsung UE46F6500 ( LED smart TV ) : 60 mperc után kikapcsol = Megoldva
Tisztelt Fórumlakók !
A címben említett "okos" TV szépen beindul, és 60 másodperc után kikapcsol készenlétbe. Magától nem indul újra, és ha indítom, megint pontosan 60 mperc után kikapcsol. SW nem mertem frissíteni, mert nem tudom mi kapcsolja ki. Feszültségek jónak látszanak. Ha lenne valakinek ötlete hogy mi okozhatja, megköszönném !

lcd tv SAMSUNG LE40R71B relay clicking
I have this TV equipped with the source BN44-00134A.Tv does not start, it is heard how the relay is continuously coupling and disconnecting. The stable voltage drop is STB = 6.5V, P-ON / OFF varies between 0.2-2.5V in normal operation = 2.6V) PFC between 360-385V (when going is 382V). All electrolytes, secondary-primary, have been changed, except the 220uF / 450V which is ok. In this state, if measure the voltage on the pins 1-2 to optocoupler PCS802, the relay stay connect and tv work normally . I have replaced the PCS802,801, the ICS 802 (KIA431), the QP803, the QS801, the QS802 checked. If I stop it(unplugged) and I restart the tv in a few minutes, it works normally, if I leave it a little longer, the defect returns. Any suggestion is welcome, I do not think it would be the problem with the mainboard. Thank you!
