Part 1 Mitsubishi WD 73727 DLP Color Distortion Distorted Fix Repair V28...

A common issue and it may be your problem is dust and dirt inside the unit---the set intakes air from the front and exhausts it out the rear==I have seen several of these sets where removing rear cover and taking stthe set outside and blowing it with a air compressor clears the issue.

Fans and other critical items that get clogged or coated with a moderate amount of dust will cause this issue.

if it is a 7 then u must replace.

The "LAMP" LED light indicator is on or flashing.The tv projection lamp life are ended.Tv require a new projection lamp.

The lamp door or air vent doors are most likely not closed correctly as those doors will make the lights blink orange.

Check your lamp; it may have blown. Sound, no picture and a red light are classis signs a lamp has failed.

you have mention that after 10-15 seconds T.V starts up, will you give total description of the T.V within that 10-15 seconds?

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

the plug the connects underneath is not connecting right you have to get at the plug and seat it correctly
