The PIP looked bad, with leaking fish caps, so I done the bypass anyway,...but,...it didn't help with my problem. I need to troubleshoot the Video switching ckts., but I don't have a schematic of that area. Can anyone provide me with a pdf. file for the Video switching ckts., or at least tell me which IC , and part number I need to check ?
