I have the same problem. Went on line to suggested site and tech tell me if it is the light engine, it should be under warranty. Gave me local authorized dealer's location in my area.

There is a possibility that the symptoms that you described is covered under an additional warranty, even if your set has been out of warranty for years. Sony has a site that describes this repair at no cost to the consumer: http://esupport.sony.com/perl/news-item.pl?news_id=127&mdl=KF50WE610 If this is not covered, then, the blue light panel is going out and that means it needs a light engine. Good Luck

Little white dots in tv modle# wdt657 what are they how can i get them off


Your TV is DLP projection TV. DLP is Digital Light Processing. Digitally processed light coming out of DMD (Digital Micro mirror Device) is projected on the TV screen. This DMD is made of thousands of tiny mirrors & the size is about 0.7 inch. These mirrors are fixed with tiny hinges for its movement. They reflect light as per processed signal. DLP is invented by Texas Instruments. When there are dots on the screen, that means the tiny mirrors representing the dots are stuck in its position. If the dots are few & the viewing is bearable, just leave as it is. If the dots are more than bearable then you will have replace the DMD chip which is quite costly.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

You need a light engine. I do not remember if your model is still under Sony's recall. You might want to call them.

this is the information I received

This blue dots problem is due to defective blue lcd and related uv filters/ polarizers in optic block (light engine) and optic block will be replace to fis that issue.
It would be costly fix and an experienced tech is needed to do the job. You can expect $1000 repair cost.

There are spots on the tV that are tiny white dots. It appears that some of the tiny bulbs have burned out and I wondered if it can be fixed. There are about 5 or six scattered across the screen.


This is a failing DMD board and is really not a user replaceable item. Please contact your local TV techncian for correct part number to be ordered and replaced.
