Sziasztok!
Elment a képeltérítés. Cseréltem a TDA 8214-et 8215-re. Jól működik, de a kép felső harmadában visszafutási csíkok vannak. Hol keressem a hibát? A T593 körére gondoltam, de ott minden jó.
Kérem a segítségeteket!
Üdv Feró58
A képen sávossan rázkodnak a sorok csipkézödnek B+ kondi,tápkondik, hálozatikondi, sormeghajtó ic és csatoló kondi cserélve nem javult.
bemelegedés után kicsit jobb az állapot
de nem tökéletes.
TUD E VALAKI SEGITENI EBBEN?
