Sziasztok
A fenti tv a mellékletben csatolt képet produkálja. Mivel elég méretes feleslegesen nem hoznám el. Okozhatja ezt a hibát t-con vagy kijelzőhiba lesz?
Köszi
Balázs

Üdv.Mindenkinek!
A segítségeteket szeretném kérni,a fent emlitett gépezetnek elment a hangja.
Alapos portalanitás és egy gyári vissza állítás után még mint egy 3 órát szólt,
és most megint előjött a hiba.
Van ennek valami tip.hibája?
Köszönöm:

I copied the spi flash and nand from a working board of the same model, but it still won't turn on and the standby LED flashes 13 times. Before reprogramming, the LED also flashed and the TV wouldn't turn on. It also wasn't possible to upload software via USB. I read this via UART:

Sziasztok!
Segítséget kérek, feladtam, nincs több ötletem! A jelenség: kép alsó felét felgyűri, 5-7 perc után a kép kisimul,normál geometriájú lesz. A tv TDA 1771-el megy, (cserélve), az összes elkó cserélve-( ESR-rel mérve kicsit gyengék, de nem jelentősen)-a képeltérítő fokban. Változás semmi. Nanók kicserélve-semmi. Táp nem változik -27V-, nem brummos, szűrő elkó cserélve. Ellenállások ha csak el nem b....tam nincsenek felnyúlva. Fűrészfog szép, nem változik. Itt a vége- meg az ötleteimnek is! Ha van valakinek, kérem ossza meg velem! Előre is köszi!
