Sharp 70gs-64
Sziasztok, Valaki tudna segíteni ? Egyes csatornák nagyon zajosak , mások élesek. Ami zajos pl. RTL Klub, TV2 (UPC) De minden más tv-n kipróbálva a csatornák tiszták. Sajnos ezen a tipuson csak automata hangolás van. Talán ha lenne finomhangolás. Ez tipushiba vagy lehet valamit orvosolni ?? Üdv : András
Sharp LC 37 DH65 E
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.
