Contine st92195 stv2248h iar in sursa tda16846.Am inlocuit finalul linii st1803...verificat u1=115v.Acum functioneaza dar imi intrerupe imaginea cand misc de placa.(dispare si inalta)sonorul fiind normal.Pinii 53=5v respectiv 45=7.8v la procesor sunt alimentati si atunci cand intrerupe imaginea.Am masurat legatura dintre pin48 si prefinal linii ,colectorul prefinalului este alimentat normal.(nu am osciloscop).Pe pin 48 am 2v cad am inalta si 8v cand dispare.Va rog frumos daca se poate un sfat Am lipit si pinii procesorului pe o parte(29-56).

Am mai lipit smdurile asa cum mi-ati spus si acelasi fenomen.Cate odata porneste foarte greu sau chiar deloc.Am incalzit partea placata in zona procesorului cu feionul si a luat-o imediat.Acum misc de placa cum vreau si nu mai intrerupe.Daca se raceste putin si misc o ia de la capat cu intreruperile..Ce se intimpla nu-mi dau seama?
