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!
Bekapcsoláskor csak villog a stby led.Elsőként mindent átmérve a tápok jók a firmware szorulna frissítésre, átnézve a topikokat nem találtam ilyet.
Bízom benne, hogy azóta akadt valakinél.
Ebben kérnék segítséget tőletek.
Köszönettel : Laci
I greet you! This TV starts with the SHARP logo and so it stays, it doesn't "do" anything else. It is equipped with mainboard + power: TP.MS6486 PB710
display: LQ315T3HC4U
Serial No: B32CH5242EB27W38112070900233
I think it's a software problem, can we find something, possibly via usb? From what I found, nothing really "fits". Thanks!

Üdv!
Alany nem indul. Rövid méregetés után kiderült, hogy nincs sorimpulzus, ill. van, de csak valami bolhafing.
Rajz:

Lekötöttem mindent IC801 HOUT lábáról és közvetlenül rámértem szkóppal. Van valami ami négyszögre emlékeztet, de csak pár tized volt. A rajz szerint ém úgy gondolom, hogy itt legalább 8 voltnak kellene lennie.
Van-e bárkinek bármi ötlete az IC cseréjén kívül?
Az IC STV2236, hqvideo nem ismeri, sini szerint nem szállítható.
