You have to remove the lower panel on the back of your tv, then remove the light engine. Unhook the wires attached to the DMD board. Remove the DMD board. Remove the heat cink from the DMD board. remove the optical lens but don't touch the lens. There is a video on shopjimmy.com that shows the entire procedure. Takes 2 hours. The optical lens can be cleaned with an eyeglass cloth, same for the DLP chip lens. no wet solutions on lenses. Remove dust from other internal parts with compressed air in a can. Your picture will be clean and clear. Wear latex gloves and make sure you are grounded to prevent static electricity.

Sounds like the back light has gone mate. Unfortunately this usually makes the tv obsolete

Your problem is that the DMD device is failing. You're in luck, though. Mitubishi has recently released a replacement DMD device in order to keep repair costs down for the consumer. Take your TV to an authorized Mitsubishi servicer for repairs.

Hello. Please call Mitsubishi! Some models the DLP chip is covered under warranty, and all you have to do is pay labor costs, our shop charges $200.

Your lamp door switch isnt activated. either the door isnt secure or the wire isnt plugged in. Flashing orangy red LED means just that.

Check your lamp. The popping sound was most likely the arc tube exploding. Make sure you only install a real Philips or Osram lamp. WD73737 Mitsubishi Genuine High Quality Original Projector Lamps now...

That may be a power supply problem. The capacitors are known for failure. check google for "wd73827 capacitors"

May want to check your bulb. They only last 3or4 years

Mitsubishi... | Answered on Jan 08, 2015

Hello, first off the set was last made in 2006, so it's 8 years old. Have you checked to see if the lamp is bad? Disregard "Houndog101"'s remarks, they are for an older crt projection tv. If the lamp is ok, it may be the color wheel has failed, a power supply or a bad ballast board, but my first guess would be the lamp part number 915P027010. Let me know what you find on the lamp.....tks
