Our '06 Mitsubishi dlp TV was under warranty when a defective light engine was diagnosed by a certified tech after 10 months. It was replaced after a three month wait at which time another light engine was installed.That one lasted three days,at which time another was ordered and we waited again. Now the third light engine is defective after 10 days. HELP!!

Contact Mitsubishi with the proof of this and demand a new TV set. Maybe it is the service shop causing this, your warranty should also be extended for the time you were out of the use of the TV set while waiting for parts. If this does not work, the state attorneys office should be able to get you a new set or at least this one repaired. Good Luck

Hi, I have a mitsubishi 65" DLP model # 65733 that I bought in December 2007 brand new, about six months ago I started spoting white dots on my screen that started blinking and then became permanent, thinking is was dust I cleaned everything inside with compressed air without success.
The stars multiply daily to a point that it was intolerable to watch anything with all the white stars and a few black ones that showed up.
We called mitsubishi but got no where, I was out of warranty. (they still deny having a problem with their DLP's)
I had a service tech inspect the tv and was told it could run about $800 to $1000 to replace the light engine with refurbished parts with 90 day warranties.
Researching on line I came across a DLP chip that is compatible with several mitsubishi and samsung models, so I decided to chance it, and replace just the DMD chip before we trash the tv, it was unthinkable to pay $800 to repair a tv that we could buy now for under $900.
Thanks God the "gamble" paid out and the problem got solve with just $150 DLP chip in about 15 minutes of my time.
If you are not mechanically nor electronically inclined, I recommend you use a technician for the installation, but don't let anyone tell you you need to replace the whole light engine, it is a ripoff.
If your problem is just white or black dots on the screen that do not move.......this will solve your problem!!
P.S. Hope this will help you and for the record..... "I will never buy a mitsubishi product again".
Call Encompass Parts 1800-638-3328 or look them up online they list your TV as well as Service Manual and Keep in Mind just because Light Engine was replaced 3 months ago does not mean it cannot be same Problem so if you have any warranty on it replace it again!
Mitsubishi extended the warranty on THIS model to 3 years. Check your manufacture date on the back of the TV, , Then call Mitsubishi. They are replacing light engines and/or replacing TVs with newer models without the problem part.
That problem with the "AIRFLOW Blocked" is now covered by Mitsubishi (parts & labor) Contact a good repair shop and they should fix it free. I had that same problem the tech came out and fixed it in about 30min.
Replace the 1000uf capacitors on the DM board. thats whats causiong the problem. If you need further help go to this link they have your service manual available for emailing after purchase and that will entitle you for free tech support and one of their techs can fix those sets in his sleep he will walk you through the repair which parts are only about 20 dollars to fix the problem. http://servicemanuals.vstore.ca/
I recently repaired a Mitsubishi DLP for a similar symptom. Found C9a37 and C9a38 in the power supply to be defective. They feed the light engine driver. The power supply module is located all the way up front on the left side of the chassis looking from the rear. The module is also shielded so you will have to remove the shields to locate the capacitors. The value of the caps are 3300mf/25v. Good luck
