Sony KV-25R2K ( FE1 ) tápegység nem indúl! Kész!
Sziasztok! Azzal a hibával hozták, hogy nem világit a készenléti led. szétszedés után belenézve, a biztosíték szakadt volt, és a STR-F6654 pedig zárlatos volt. Most hogy megjött az ic, beforrasztva nem indul el a táp, és a készenléti led kettőt villan ( Nagy táp gond ). Átmérve az ellenállásokat, diódákat nem találtam rosszat, az icén kivül cseréltem az optót, 100uf, és 1uf. Bekapcsoláskor még egy pillanatra sem jön meg a tápfeszültség, a puffer feszültség az meg van. A sorvég tranzisztor nélkül sincs meg.

Sony KDL-40EX1 , no sound and no picture, power and backlite is there
Dear forum members, Perhaps anybody can help me with the Sony KDL-40EX1 TV set. I have this set here for repair , but I have no experience with this type of TV. It has a media box and sents the TV information wireless tot the TV. My problem is on the tv: no picture and no sound , the backlite works because I see white light behind the screen. There is also wireless communication because I can turn the TV on and off with the switch on the media box and on the TV itself. I have the service manual but this doesn't really help me any. So the power board seems to be working because I have high voltage for the ccf tubes and 12V for the rest of the TV. It is my idea that perhaps the main board is defective because I have no picture and no sound but I am not sure. Is there anybody here on this forum that can help me with some idea's. Thanks Fred Dijksman
