Colorwheel eeds replacement most likley it could also be a fan but I would assume its the colorwheel especially if it was real highpitched sort of squealing sound. You can get the colorwheel and free tech assistance from the guys over at www.tvrepairworld.com

Possible lamp but:

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

44 = DVI cable between FMT and Engine disconnected

Issue is most likely with the optical light engine the model listed here uses, no mystery and very common issue.

I have to ask if it was a Mitsubishi made lamp and what caused you to replace it?

white spots is not likely to be a cleaning issue==more likely if tiny spots a bad optical light engine.

The clue here would be if you had a HD box etc that also uses HDMI to see if it works there or not----and does it work on another HDMI (set ought to have two of them?) If something other than the game will not work on that input the socket is damaged---most of these sets if that happens the board it is on has to be REPLACED.

check the ballast leads which enter the rear of the lamp compartmnent they can tend to get pushed in slightly and prevent a good connection to the lamp. If the connections all look good then the lamp driver (ballast) is most likely defective
