There are two and sometimes three very large IC’s that control the convergence in a big screen set. I think that you have two that are on the board in the center of the set. They are secured to a very large aluminum heat sink.

There are two ways to repair intermittent connections on the convergence IC’s. I usually remove the board with the convergence IC’s on them and then and solder the connections. The other method is to tilt the circuit board and solder them while still installed in the chassis.

If you remove the board and repair the connections, be careful to remember which connections need to be made when you replace the board. Mitsubishi uses a lettering system, so it should be easy.

If the problem remains after you have made the repair, it is possible that the pins on the IC’s have become loose. In this case the IC’s need to be replaced. I have seen this on several occasions.

If you choose to repair the set yourself, be very careful of the high voltage that can be stored in the capacitors, and CRT’s. This voltage can be as high as 30,000 volts.


I hope this information allows you to resolve this issue.

Mits 46805 - Replaced IC's now picture is dim!


Good Day, Nickb2b;

The IC's you installed will not cause a dark/dim picture......but I would like you to check two things:

1. Make sure you put all cables that you may have unplugged into their proper positions, the cables are marked with numbers, ensure all cables are properly seated,

2. Look for fluid on the PCB's.

Good Luck, big IRISH.

Good Day, Corri;

It sounds like the TV has a Circuit problem in the convergence circuit. If it comes and goes then the concern can be corrected by re-soldering the 'conv' output IC"s. A semi-minor repair and cost.

Good Luck, big IRISH.
