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.

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.

SOURCE: I have a 73 inch Mitsubishi television the indicator light stays on when you turn it on... no picture shows and when it turns off that's when you hear the sound. the model number is WD 73642

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Bad picture


Good Day, tater5;

Sounds like you have a convergence problem. If the picture is bowed, please repair as soon as possible before 'the problem' causes additional concerns. It sound's like the 'conv' IC's have failed.

If you are handy the convergence IC's are big and black and attached to a large heat sink and will have numbers like STK 392-something.

Not handy? Then call a factory authorized service dealer to fix this for you.

Good Luck, big IRISH.

Half Dead mitsubishi wt-46805


This condition can be caused by multiple failures, however this unit has chronic bad yoke connections. Difficult repair for a layman but not for a tech or shop. Most likely 200 to 250 for that repair. Other more serious failures sure to cost more.
