Üdv. Mindenkinek . Pár perc után a kép elhomályosodik átmegy negatíva és eltűnik , a hang marad és ilyenkor a készülék áramfelvétele 0.8-1A-rol leesik 0.2A. Elég nehéz hozzáférni működés közben a controlboard-hoz , de mint ha azon a BGA ic kocogtatására változna a kép. Lehet azt valahogy "házilag hőkezelni" , vagy panel csere ?
