berniedd Posted March 28, 2006 Report Share Posted March 28, 2006 Hi all. i'm troubleshooting my CRT monitor and need a schematic to go. I think it's the jungle IC (STV7778) but I gotta check out other components before I replace that 42-pin chip. Symptoms: Loss of vertical sweep (horizontal line across screen) that quickly returns to normal. Later this transformed into a vertical and horizontal shrinkage of the image, accompanied by decreased brightness. It's intermittent and sometimes returns to normal, sometimes it doesn't. I've already resoldered all cold joints. Still no dice. Quote Link to comment Share on other sites More sharing options...
