Hi diane
To answer your question;
Those blue dots are burnt pixels.
These usually happen on plasma tv`s much younger than yours.
I`m afraid that there isn`t much that you can do beside replacing the whole screen assembly, which would be cost prohibitive beside the fact that it is no longer available from sony.
Hope this help
By the way i believe that the other expert you talked to , somehow thought that your tv was the DLP type

This is an optical block issue. Please provide me the exact model number of your Sony Flat screen so that I could search for the exact part number of the component that you need to replace.

Thank you!

4 year old 60inch sony flat screen purchased in 2005


sounds like heat got to the optical block, there are some websites that can give you prices on rebuilt opt units, but i suggest that you take a look at the sony website and check the factory recall section to see if there are any re-calls on your particular model. These optical units are kind of expensive.

Blue section (corner) and blue dots


This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

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.

Horizontal (dashed) line across screen


On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

Blue dots


You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time
