Hi there happy to help.

 

Can you tell me what these "stuck pixels" look like? Are they white specs?

 

Does the screen do this on all inputs?

 

Let me know,

OK here is what is going on.....


The DMD chip/board on your TV is failing.
This is the chip with the "tiny mirrors" invented by texas instruments a few years back that is the heart of the DLP light engine.
This is not good news as 9 times out of 10 it is cheaper to replace the TV than perform this repair.
Most people live with the problem until the TV becomes unwatchable and then replace.

 

HOWEVER, with a TV your size and only a couple years old, I believe it will be worth repairing.

 

If you give me the exact model number I can locate some parts and be able to give you a better estimate at what the parts and labor will run you here.

 

Let me know,

OK,

 

Looks like this part will run around $650(after core deposit), .....see here....

Add in about 300 for labor to have this done(I do not recommend this as a do-it-yourself job), and you're looking at a 900 dollar + repair here. So I retract that you should repair this. The TV simply isn't worth this much. See here.......

Sorry for the news here,but no sense throwing good money after bad. I don't recommed DLPs for this very reason. We are seeing this ALOT with the aging fleet of DLP TVs.

 

You may consider calling Mitsubishi customer service and letting them know about this. I'm sure they heard this from customers before,but this is an expensive TV to only last 3 years.
