Greetings! So I disassembled my working Hantarex MTC 9000 for cleaning, meaning I disconnected the chassis and neck board. When I put everything back together, I had no picture at all. Playing around with the contrast pot on the chassis, I got color blue showing normally, but no red or green. Then I played around with the RGB gain and cutoff on the neck board, and I got all colors showing properly, but the screen is really dark. If I turn up the contrast, I can get the screen to a proper brightness, but the colors bleed horizontally like crazy. What could be the problem?
