The device is a sharp lc-40le540e and has the following defects: pressing the power key on the TVC lights blue LED on the front but there are no backlight, video and audio.
In practice, in addition to the LED it does not light another, could be a problem of the power adapter?
Thank you very much
Üdv Mesterek!
Van ez a tv ami fél, egy óra (változó) üzem után leáll, majd néhány perc után megy.
Mikor leáll nincs stby, nincs hibajel. Bizonyos időközönként csinálja...
Stby táp megy 4V(stby érték) meg van (üzemben 5V ekkor van 12V és 24V is )
Az smd stby tranyót cseréltem a mainen.A tápban az összes elkót, optót,TL431-t és a TNY277 ic-t.
Sziasztok!
Ma néztem bele ebbe a tvébe, el volt ugorva a gratz 4db diódája, és púpos még a 68uf/450V elkó is. Ezek cseréje után, csak annyit csinál hogy a lámpa világit, és a piros-zöld led egyszerre világit. Tápfeszek meg vannak, de találtam egy smd dióda helyét Q506, de a rajzon nem találtam hogy milyen tranzisztor lenne, és még egy helyen a fólia is megégett. Valaki megtudná nézni mi van ott?
Üdvözletem az uraknak!
Nevezett készülék, melynek tip.: LC32SD1E,került hozzám a napokban nem indul, standby sincs elvileg cseréltek benne tápot, de nem javult meg,méregetem néhány feszkót amit találtam az a 13.5v és +24 volt van a 35volt helyén de le csökken szinte 0-ra egy kis idő elteltével, nem tudom érdemes -e másik tápot tenni bele vagy main csere? Köszönöm! :)
