these white spots are caused by a bad DMD chip
call Mitsubishi and they will find a servicer and send the part to them for repair. You will only have to pay the labor

No such error code that I can find, try to unplug and let it fail again, then do the check again.

Mitsubishi is replacing these DMD IC chips nationwide under an unannounced kind of recall for model #'s WD60C9, WD73733, WD57734, WDY657, WD73734, WD65735, WD60735, WD65C9, WD73840, WD65833, WD65733, WD73735, WD73833, WD57733, WD65734 and others. Call them @ 800-332-2119 and give them your model, serial # and date of purchase, tell them you have the white spots, they will set up a workorder with a local Mitsubishi servicer to come to your home and replace the DMD chip. Mitsubishi will supply the part (part # 276P595010) for free, but you must pay $200 in labor. BUT...if you ask for Shantell Hebert when you call Mitsubishi, and really push the issue, she will also pay half of the $200 labor fee, so you go from $400 to repair to only $100. Once that chip is replaced, the unit works great again!!

A 37 error code means one of your fans is bad. It would either be the DMD fan, or the lamp fan. Take the back cover off of the set and tape down your lamp safty switch. Turn the TV on and see which fan is not working, and replace.

If you removed the plate beneath the screen on front a door should be there or it is possible it is one with the door on back--clearly marked.

Replace the DLP chip at cost between $160-$300 for the part and about two hours of your own time to do it.

The projection engine have problems,it the cause.Two years tv shouldn't have this problems already.Call talk to mitsubishi,might get some help the cost of the repair.

Well here's the scoop. White spots mean that the mirrors are stuck "on" reflecting light. Black spots mean that other mirrors are not actuating and are not reflecting light. In any case the DMD bs or the DMD chip needs to be replaced by a trained Samsung tech only.
The DMD bd controls the DMD chip.
