You probably have a V26 chassis. The only fix to this problem now that parts are no longer available from MITS is to call their Consumer relations dept. at 800-332-2119. If you have a qualified tech come out and estimate the job, Mits will offer you an attractive discount on a new model. To repair your problem would be around $750
Many different mitsubishi's have problems with voltage regulators going out and causing wavy diagonal lines that scroll the picture from top to bottom or vice versa. Without a model number it's difficult to clarify.
I think that means your FMT brd is going out. you can have a mitsubishi authorized service center come out and send an estimate to mitsubishi for help on the repair, or have a service center come out and repair it, usually about 300-500 out of pocket either way
The best way to clear the picture on these sets is to remove the screen and clean the mirrors. If it is still not clear after that it may be a bad lamp or failing capacitors in the chassis. They cause wavy lines and makes the picture blurry.
Bad capacitors. On my set HDMI looks clear, but component inputs have moving horizontal lines. There's a guy named Tbully on AVS forum that did a PowerPoint presentation that will point you to the capacitors to change. Sorry I don't have a link at this time.
The cable box signal on the components video have a too high refresh rate frequency, that is the reason for the lines. Use RCA cables or an alternative connection. Other solution is changing the display out settings for cable box (from PAL to NTSC etc.)
