I have a wd-57734 thats just over 2yrs old, it has a defective dmd chip and there's thousands of white dots all over the screen.
I had a repairman come out to figure out the problem, I was told the chip in no way should go out in just 2yrs and it was defective.
I contacted Mitsubishi several times and they will not help even get a replacement part, they also wanted me to pay $150.00 for a repairman of thiers to come out to check the problem, I had already paid $80.00 for the same thing but they won't accept that so now I have a tv that I paid alot for and can't watch. Terrible service, faulty products, stay away from mitsubishi dlp tv's or you'll have to buy again in a couple of years!

I own the same Make and Model. I also have thousands of dots across my tv. Unfortunately my TV is out of warranty and they want to have a certified Mitsubishi repairman come replace the chip at a cost of $300 to me. Mitsubishi will pick up the tab for the replacement chip. I paid $1600 for my TV and I have already replaced a bulb which I do consider normal wear and tear but I am not sinking another penny into this faulty product. I was hoping someone knew of a class action lawsuit we could file to get replacement TV's. My only advice to you is to continue to call and contact the Better Business Bureau to report them.
