YOU HAVE EITHER A DEFECTIVE OPTICAL ENGINE ASSEMBLY OR THE OPTICAL ENGINE IS JUST DIRTY INTERNALLY. IF YOU CAN TURN THE TV OFF AND STILL SEE THE BLUE SPOTS AFTER THE VIDEO GOES AWAY THEN IT WILL BE DEFECTIVE OPTICAL ENGINE IF NOT THEN IT IS MOST LIKELY DIRTY OPTICAL ENGINE.

Mitsubishi DLP W62627 displays lotsof yellow and blue...color is not right, although picture seems ok do I need to replace lamp or is it more ??


Try to reseat the DVI cable between the chassis and optical engine. If this doesn't fix the problem, you will have to replace the optical engine. The lamp is not causing this problem. A new optical engine can be pricey. You would have to get it from Mitsubishi. $450 + $300 core charge. You do get the core charge back when you send in the bad optical engine.

Sony Grand Wega corners are blue


Hello Wealth744:

The problem is that your LCD optics Engine is failing. There are three small screens much like the size of a nono Ipod screen, inside of the optics engine. Each one a different color Red, Green, Blue. The blue lcd screen is faulty.These can be replaced but labor to do this is intensive and most tech will want to just replace the optics engine. So in short the Optics Engine need to be replaced to correct this problem.

Not a problem - just clarification


They are the same part. Sony reffers to it as the optical block, while other manufacturers call it the light engine.
