Hi,
Mitsubishi WD-73286 is DLP tv that does not have any convergence circuit inside.
Convergence is required in old model rear projection tv that has three basic colors picture tubes to generate color picture that projected on front screen of tv.
DLP tv has light engine to generate picture, it is similar to multimedia projector that throws its picture on wall.
Hope this info will help.
Thanks.

Unplug the tv for about a minute - plug it in and press the reset button on the front of the tv - hold it until the light blinks. The set should come on in a minute of two - if not try the same routine again.

You need to replace the DLP chip to resolve this issue.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

If you get audio, the lamp needs to be replaced. Refer to the manual as to how to replace the lamp to confirm. Contact Mitsubishi for a replacement. Cheapest available and is OEM.

unplug all inputs you have going to the tv then hook them back up one at a time testing each ones operation. cable box first

It will cost you probably in the area of $700.00 to replace the Light Engine. I don't think it would be a good idea to repair it. DLP sets have been out of production a few years now due to high failure rates of the light engines for all makes and models and the consumer cost for the lamp.

Your problem is not in your settings. You have weak capacitors in the the vertical section or the high voltage section of your TV. The back of the set will have to be taken off and speacial equipment will have to be used to troubleshoot it. (multimeter with capacitance check). Check for weak caps and replace with the same farad rating but slightly higher voltage rateing caps. This will fix your problem.

Well lets take this one at a time. Your first problem is most likely to be related to over heating. Take off the back cover and empty a compressed air can on the back cover(near the vents) and on the boards. Just to be sure what is the status of the temp light at the front and the color?
