Have TV Questions? Ask a TV Technician
Sorry to hear about your problem. I will be happy to help.
The most likely problem is that your projection lamp has failed. The lamp is just a very high power light bulb. It needs to be changed every so often so they are fairly inexpensive and easy to change (just goes in a trap door on the Tv). Do not get a generic lamp. Here is a good place to get the lamp you need: http://www.dlplampsource.com/

I recently recieved a replacement lamp for my tv. They sent me a model wd-60737. It wasn't the same size and the plug in was in the wrong place. I started to look at the bulb and noticed that they were alike.
So, I removed the bulb and put in my old housing unit. It was the same brand bulb and the numbers were the same except for the number said 150-180 instead of just 180 on my old bulb.
I installed last night and it came on fine, picture looked perfect...Then after about 5 minutes the picture started to flicker and the colors dulled. Also I heard a weird sound like a fan or something. Kind of like it wasn't spinning all the way. It would spin and then slow down and speed up, didn't sound right.
I reset the tv and turned back on and the same thing happened after a few minutes. After I wait 5 minutes and turn it back on it comes on with a perfect picture, but after a few minutes will start flickering and the colors get dull and loses picture quality. I turn it off to make sure I'm not hurting anything.
Any ideas on what this could be?
I would like to help you but it's almost 3 months later and you never clicked accept for my original anwer.
Are you kidding? I paid you $29. I just got the part in, that is the reason. I wanted to see if that resolved the problem.
So, if you can't help me I guess I can find someone that is willing. What was the $29 for if you aren't willing to follow through and make sure my problem is resolved?
Did you get paid the $29 fee for the question? I was under the impression that you already got paid for my question? If you didn't I would be happy to help get it to you.
The reason I didn't accept answer is I was waiting until we ordered the part so I could see if that fixed the problem...
What is the full model number of your Tv?
What is the model of the lamp that you got? (wd-60737 is not a lamp model number)
Was the Tv sitting dead for the past 2 months and you only just now got the lamp?
This is the model # XXXXX my original lamp- 915B441001
The one I recently put in was 915B403001. The lamp housing didn't fit so I put in the bulb into my old lamp housing.
I have a 60" DLP 3D capable Mitsubishi 1080 rear projection tv. I don't have the exact model # XXXXX will be home later and can get it for you if you need it.
We were using our other tv for the last couple of months. So, yes our TV has been sitting idle for that time frame.
Sorry, I had to work late tonight. The model # XXXXX XXXXX
The way you described the color wheel is a lot like what I saw and heard. Would it just be a coincidence that it is going out at the same time I'm replacing a bulb? The bulb I have is it compatible with my TV?
The lamp is compatible and here is no way it could cause the colorwheel to fail. Yes, it seems to be a coincidence. Here is the colorwheel for your Tv:
Lamps usually last about 6000-8000 hours, so depends on use. The colorwheel should last at least 4 years. So no, they should not fail in 13 months. If I were you, I would be contacting Mitsubishi and complaining. Even though technically the warranty is 12 months, you can still try. For best results be persistent, polite, and patient.

I wish I could help you with billing questions but they keep us Experts in the dark about such things. All I can suggest is you contact customer service and maybe they can help you leave a bonus manually somehow. Much appreciated.
If it was a fan, the Tv would detect that, shut down, and then an error code could be extracted telling you which fan. The only thing left that I can think of is the ballast. It sends high voltage to the lamp.
I would suggest you run the Tv with the back off (tape down the lamp door switch). When it starts to flicker, look and listen around the back. Try to determine where the noise is coming from and if the lamp itself is flickering.
Unplug the Tv from power.
Double check that lamp door switch. Get the door and look at the little tab that holds the switch down. It has to be pressed down pretty far. Stuff a little wad of paper in there or something.
Plug the Tv back in.
What do you have hooked up to the Tv?
Is it flickering on all the inputs?
If you press Menu on the Tv remote, is that flickering too?
The only thing between the lamp and the screen that can cause flickering picture is the colorwheel and the internal parts of the optical engine. Since you already tried colorwheel, the only thing left is the optical engine. The parts in there cannot be changed, the whole thing has to be replaced as one unit. Don't know about the "squeal noise every now and then", without being there.
Doubtful both colorwheels are bad.
Yes, sure lamps are compatible.
If it was the ballast or lamp, you should be able to visually see the lamp flickering at the same rate as on the screen.
Some places to buy the engine:
Yes, any part can fail at any time due to many factors from improper manufacturing to design flaw to extreme conditions etc.
I called Mitsubishi to see what they will do. They need some info from me to consider options. One thing they asked was are you a certified Mitsubishi tech? If so, I need some sort of confirmation from you.
I worked for a Mitsubishi authorized service center for 5 years as an in home service technician. We were given direct access to the factory engineers and parts. One year ago the company had to lay off over 50% of it's technicians and I was not one of the lucky ones. The company is still in business but I cannot use those credentials since I am no longer employed by them. You will need to find your local authorized servicer http://support.mitsubishi-tv.com/service
