I "fixed" a 1986 Mitsubishi 36" rear projection TV with a bad M50441-561BSP
(IC701). It was not easy (the first time) and there was a small cost of function. I
bypassed the tuner control circuit (with the cut of one wire) and then fed in the
video signal from my VCR into the rear Video 1 input. I now use my VCR to change
channels but I still get to see the picture in 36" size! I also had to make a patch to
regain volume control. Contact me for details of the fix. The total fix required
cutting 4 wires, adding 1 jumper and one 100k pot all right next to IC701.
