I got a used 4000 on ebay, it seems to be in working order, except for some lines in the LCD, and when adjusting the contrast knob, it cuts the LCD in and out. You have to get the knob at the perfect spot for it to display.
Any suggestions on going about troubleshooting this? It seems as though there'd be 2 parts to replace:
1. a new LCD screen obviously, or
2. http://www.mpcstuff.com/1a820602x.html - Contrast adjuster POT
Any suggestions?
