Question about Mitsubishi WD-57732 Projection Television

1 Answer

Trouble turning on

Recently started having a problem with my Mitsubishi WD-57732 rear projection TV. When you try to turn the tv on after it has been off for a few minutes, the green timer/status light begins to blink fast. It now takes about a minute for my tv to turn on. Never had the problem before a few days ago. Any suggestions?

    Held them down and got this code, 1 blink pause then 2 blinks. Then it seemed to repeat itself a few times before staying on all the time. What does this mean?

    Have someone coming to take a look at it on Wednesday, it is less than one year old so still under warranty. Was hoping to get a leg up and tell the technician what was wrong. Any advice on what I should tell him or can they just replace the whole DM board? What does DM mean? All your advice has been extremely helpful.

    Our status light is yellow when we turn it on and it tells us that the tv will shut off in a few seconds and to check if the air flow is blocked. Our lamp light is also blinking. The picture comes on fine with this message until it shuts off. We can find no problems with the air. Any ideas? The set is just over a year old.

Try pushing the Imput and Menu buttons in together on the set and hold for 5 minutes and see if it blinks out a two digit code. Then let me know. Also these sets have a tendency to have some faulty capacitors on the DM board. Hope this helps youout.

    OK the code you mention is 12 which means the internal diagnosis doesnt recognise any faults. I would suggest looking it over for solder cracks around the flyback and horizontal transformer as well as the verticle and horizontal youk pins. If everything looks good with a magnifying glass then I would look at all the capacitots for signs of swelling or the wrappers shrinking do to heat. This model has a history of having some bad capacitors on the DM board (power supply) Hope this helps, let me know.

    The DM board is the power supply. If its still under warranty thats good.Let them diagnose it for you, you may want to tell him that you have heard on line about the DM boards needing replacement see what he says. Glad I could be of assistance.

How can you diagnose a failed lamp in a Mitsubishi DLP WD 52631


Remove the lamp and do a visual inspection.
If this is a DLP you may have a bad color wheel! whistling sound is a sign of color wheel.

Good luck to you

The lamp needs to be replaced. It's on the back and easy to do. I replaced mine about 3 months ago and it was about $182.00. Hope this works, I know it's hard to fork out that kind of money at this time but once you do the TV will be as good as new. Take care

My tv keeps shutting down when I turn on. The message on the the TV screen said that "the TV will be shutting down in a few minutes". I resit the lamp in the back of the TV and the TV works after I reset...


The first would be excessive dust causing inadequate airflow through the lamp cage. Cleaning the filter may resolve the problem.

It could also be that one, or both, of the temperature sensors could be defective. This is a known problem to the extent that Mitsubishi extended the warranty an extra two years on your model and similar models with the same design.

Mitsubishi Digital Electronics America, Inc (MDEA) 2006 DLP® Projection Televisions Models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD- 65732, WD-57831, WD-65831.
As part of our commitment to quality and customer satisfaction, MDEA is announcing an extension of the warranty coverage to replace the thermal sensor for the above referenced models. For a period of two additional years beyond the one year limited warranty, MDEA will cover the cost of the thermal sensor (parts and labor) at no charge. All other terms of the MDEA limited warranty will continue to apply.
