    I have the same problem, it started with one light blue line at the bottom of the screen and day by day it slowly moves all over. Now we have HUNDREDS of blue lights all over our screen

    The blue across the bottom is not so much a line as it is a blue "fog" about 4" high. It varies in shape and intensity.

Once again, this is a problem with the optical block or light engine assy. The LCD panels have been damaged by excessive heat from the lamp. Sony has been directed by the New York state attorney general's office to extend warranties on these sets for models going back 4 years. Call Sony at 1-800-222-SONY for assistance.

I have blue dots all over my screen aa well as


Hi,
This blue dot and hue problem is due to bad lcd in your tv as its Sony dlp tv that has optics block, that is also called light engine, it consists of 3 lcds, filters and lamp to produce an image that projects on front screen.
In this tv, blue lcd became defective and complete light engine will be replaced to get it fixed.
As other expert talking about blue CRT (cathode ray tube) that does not exist in this tv and my fellow expert has no idea about this kind of tv, sorry for that.
Hope this info will help you, let me know if you have additional question.
Thanks.

Blue dots on screen plus ghosting on screen


The optical block is defective. Contact Sony support. Sometimes they will warranty these even after the 1yr warranty has expired. Have your model and serial numbers handy.

HDTV is getting blue dots and the right side has turned blue


These issues are problems in the light engine (optics block)
the dots are called "starfield" and the geometric is "roadmap"
replacing the light engine will fix the issue. for awhile, sony was extending the warrany on the engine for these issues only, but that may have expired.
