Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

Mitsubishi 46" Rear Projection TV

My TV goes out of alignment and I can temporarily fix it my smacking it on the side (really, no kidding). It's OK for a while, then shifts back out of convergence. Does this indicate a loose connection or something that I can possibly fix myself.

I have a Mitsubishi WS55809 that I purchased in 2002, and my kids have been using it for gaming. As they are playing, the screen convergence will change constantly from a normal image, to a "bow...


Unless you've moved the unit lately, or the kids have treated it roughly, it's probably not the mirror, which is fixed in place with screws on this model.
You can also take a look at this website here, which describes some solutions to bowing problems, specifically replacing the convergence ICs. However, this is expensive, provided you can still find parts, and probably isn't your problem, anyway.
Since whacking the unit fixes and un-fixes the problem, it's more than likely a connector that's loose. If you know your way around the inside of a TV, you can unplug, clean, and re-plug the various boards and connectors, especially the convergence and deflector boards. That will likely solve your problem
CAUTION: If you don't know your way around the inside of a TV, DON'T OPEN IT! Even after unplugging the TV, some of the wires inside will have enough voltage to cause serious injury. Better to be safe than sorry.

The picture gets a bow effect, smacking the side of the tv helps temporarily. Is it the bulb, wiring problem or what


loose solder connections on your convergence ics ..you should get this fixed quick..the loose connections on the convergence ics can short them out..this will be more expensive to repair then a simple solder job.

Wt-46809 has convergance issues


Replacing the Convergence IC's should do the trick. But it is not a easy repair do to the disassembly requierments. I would recommend calling Mitsubishi at 18003322119 to get a local service facility to come out and give you a estimate to repair.
