Hi group. Here is an update as I said I would post. I replaced the stereo decoder as suggested and this fixed the distorted audio. Here's the history: Plugged the set in to see what the probelm was - friend said picture and sound went out. Had a perfect picture, distorted sound, then after a few minutes the raster went black, still had sound. I turned up the screen voltage slightly and saw a horizontal red line. Replaced the vertical IC but no change. I resoldered the jungle IC also, and checked the deflection coil - 3.5ohms. Should I be looking for a high ESR cap? I would signal trace the vertical but I don't have the schematic. Which pin of the jungle IC should I start from? I am fairly new to repair, so without the schematic I am shooting in the dark. I was hoping someone could give me some tips, since I would rather not have to purchase the schematic. Web search came up empty on free schematic. Thanks again group, and I will continue posting progress.
