Samsung WS-32Z306T sorvégtranzisztor melegedése
Sziasztok! Samsung WS-32Z306T TV-ben lévő J6920 sorvégtranzisztor a használat során fokozatosan, egyre jobban melegszik. A végén már annyira forró,hogy az ember ujja már nem bírja elviselni a hűtőborda hőfokát,idővel a tranzisztor elmelegszik és zárlatos lesz. Valakinek van esetleg tapasztalata,hogy miért történik ez? Előre is köszönöm a segítséget! B
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!

Sziasztok! Ez a készülék működik, de néha gondol egyet és kikapcsol, de úgy hogy még a készenlét sem világít. De ha újra bekapcsolom megint működik, van hogy 10perc, de lehe fél óra is. Eddig a tápban a primer oldalon a két elkót, a sormeghajtás táp elkóját, és a kh hibákat átforrasztottam. Mi lehet vele táp vagy sor?
