Replying to VX2000 problem HELP

so i bought a vx for cheap a little while ago and it looks amazing, colors are perfect, fisheye is buttery, have plenty of tapes. only problem is that the tapes keep glitching, every 3 seconds or so ill get a glitch in the left side of the screen. I ran a cleaning tape quit a few times and it never resolved the issue. Also tried cleaning it manually with alcohol and that only caused problems. If anyone knows anything about these cameras or thread me to someone who does that could help me out towards resolving the issue that would be great. trying to get some good footy before the season gets going.
