Subject: [TechAssist] Zenith 9-1132 Rolling horiz. lines over picture.
> Never seen this before. This set has a perfect picture and audio except
there's horiz. lines rooling thru the pix as though the horizontal was off
frequency. I changed the video jungle IC but to no avail. Have same with
external input except a little worse. I suspect a cap somewhere. Anyone run
across this b4? Neil
