Szép napot mindenkinek!
A fenti led tv hálózatra kapcsolva beindúl. A készenléti led zölden virít,kiírja "TOSHIBA" majd kék táblára vált.Ezen kivűl semmit nem csinál. Távra,tasztra nem reagál.Bármelyik bemenetre adok jelet,semmi. A táp feszűltségek meg vannak. Az infra vevőről elmegy a táv jele.
Mi okozhatja ezt a jelenséget? Ehez kérnék segítséget.
Köszönöm:Géza

Sziasztok!
A fenti készülék hibája,hogy kb.minden ötödik pc-t fogadja az RGB bemeneten,
a többinél nincs videó jel jelenik meg. Amelyik PC-t elfogadja azon is a kép vizszintesen enyhén mozog,remeg. Más funkciók hibátlanok. Ügyfél szerint a készüléken a hiba most 3 év
után jelentkezett.
Ha van valakinek ilyen hibával tapasztalata ,ötlete kérem segitsen.
Köszönöm:
Zalai
