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
Szevasztok!
A hibajelenség a következő.Nem indul amikor feszültséget kap,a led átvált pirosról zöldre,a relé kattan.Az inverter nem indul.A zöld led elkezd kb.2 sec ritmusban villogni,a relé ismét kattan,de nincs fény.A tápfeszek a jelzetteknek megfelelő.Az inverter felé a jelzett 60 V helyett 63 V.
Közben a begombot a távon nyomkodom és egyszer beindul.Ha Stbyban hagyom, akkor a távval be lehet indítani.Így később is be lehet indítani.Amikor üzemel,akkor több óráig is rendben működik.
A Service Manualban,ha jól értelmezem az így villogó zöldre azt írja,hogy az OPC frissítés befejeződött.Lehet,hogy a fényérzékelő hibás?
Üdv.,ferenc.

Hellótok!
A tárgybéli TV minden hajnali 5 órakkor - az ő órája szerint - egy halk csippanást - nem éles, hanem tompa - ad.
Semmilyen ébresztési funkció, vagy bekapcsolás nincs beállítva rajta.
Találkoztatok már ilyennel?!
Köszönettel:szuts
