If this only occurs occassionally, it suggests that there are bad connections at the convergence ICs rather than defective ICs. If you can solder, try resoldering the pins on the ICs. That may resolve the problem. These ICs are large, black and attached to a heatsink. They will be marked STKxxx.
Keep us posted.

Toshiba big screen Model TZ50V60 Convergence Issue-Chips Replaced


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Blurry screen double vision picture


The convergence circuit has failed. It is not a easy fix due to the tear down needed to get to the circuit area. I would call Mitsubishi at 18003322119 to get a Authorized Service Facility to check it out and give you a estimate of repair cost.
