How do I repair this problem???
Someone with moderate experience would have to examine the red crt printed circuit board--I have seen some of these that develop a cracked ground path on that board but usually it is pink except on the sides depending which ground path is bad.

If the pink overlay goes away gradually, you could have weak picture tubes (CRT's) If the color jumps in after warming up, it could be a bad solder connection. If you haven't had a good picture to watch for a long time, I would be tempted to put the money towards a new HDTV set as those older Mitsubishi Rear Projection TV's had a Lot of bad solder connections in the past, and by fixing one problem another could crop up in the near future.

1)Check for coolant leak from CRT onto signal board
2)Possible convergence problem ..................T.

Does the neck of the tube glow? If not you may have a bad solder connection on the Red CRT PC board or a bad transistor on the red PC board
