WD-62525 part #915P026010

most likely if model listed is correct live with it----optical light engine would have to be replaced which is major parts and labor cost.

Not a cleaning issue.

The lamp shines into a OPTICAL LIGHT ENGINE, which has a series of lens and baffles---blue is the first part of the engine to get that light and heat---in your case the blue area is damaged from the heat----minus blue equals yellow.

The entire engine would have to be replaced--not a cheap part--Google the model number with "light engine" to get an idea of cost.

May be time to either use it as is or ?

Replacing the Light Engine is the only remedy. Cost is usually in the area of $900-1100 dollars.

Common Repairs
For the following models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD-65732, WD-57831, WD-65831, the most common repair problem stems from television shutting off almost immediately after it has been turned on accompanied by the message, "TV will shut down in a few seconds. Please check if the air flow is blocked." According to the Mitsubishi website, this issue is caused by a loose connection as a result of a faulty thermal sensor. For models: WD-73727, WD-73827, WD-73927, WD-73732, WD-7383, the most encountered repair problem has been in relation to the optical engine. Another common situation consumers have encountered is failure of the TV to turn on along with unceasing flashing of the green power light. The solution for this problem, caused by the DM board, will vary by repairman. Consumers have also encountered issues with moving vertical or horizontal lines appearing on the screen which can either be due to problems with the capacitor, light engine, or formatter board. Make sure all bad caps are changed.

It depends on the extent of any damage that needs to be repaired.

u need a new optical block or light engine , this part cost between $400 - $600

This problems is the causes by the tv Light Projection Engine.This repair is an expensive repair.The whole Light Engine must be replaced to solved this problems.Talk to Mitsubishi tv corp.might have some help with the cost of the repair.There is a design flaw on these tv the Light Egine the IC chip controller to the projection light causes problems over again and again.

It will cost you probably in the area of $700.00 to replace the Light Engine. I don't think it would be a good idea to repair it. DLP sets have been out of production a few years now due to high failure rates of the light engines for all makes and models and the consumer cost for the lamp.

I have the same tv with the same problem and have found it to be the dmd chip which controls the mirrors. Once the chip begins to go it just gets worse and eventually will have to be replaced. Unfortunately you can't just go out and buy one and replace it yourself. It is mounted on the light engine circuit board and I got an estimate on the light engine from an authorized service representative and the cost for the part alone is about $900.00. The white spots are when the mirrors get stuck in the on position and if they get stuck in the off position they display a black dot, which I also have some of them. In a month's time my tv has gone from no dots to over 100 now. I have been searching to see if there is anyone who repairs the light engines instead of buying a new one, as this would surely be cheaper and I found a company that does this, but they will not do business with consumers only repair services. They are Hong Video Technologies, so if anyone out there knows how to get these engines refurbished and what it would cost, we both would be very appreciative.
Thanks

Good Day;

More then likely your 2005 MODEL has a bad "LIGHT ENGINE". Call an Authorized Service Center and have them give you an estimate, then call MIT's and try to get them to give you a "CONCESSION". It's costly. Good Luck, big IRISH.
