The optical block is most likely causing the problem. It will continue to get worse. Sony may help with the repair since they have had a lot of problems over the years with their optical blocks across many models. On the older sets they usually only help with the parts cost. The average repair cost for a optical block replacement is $1200.00 to $1500.00. So if they help with the parts cost it really brings the cost down. Their customer service number is 1800-222-SONY.
I hope this helps,

Blue dots and streaks

Blue streaks might have been just your video connection and problem with signaling. But, blue dots is faulty light engine, aka "optical block". The engine in this could be a defective LCD array. Very expensive, a optical block is about $850. Hope it's still under warranty. You could get a rebuilt one, possibly. Need service adjustment too. Bad problem that Sony has with these kinds of sets.

Near the bottom edge of the screen on my Wega KF-50WE 610 has appeared a ''blue haze'' that appears after the TV has warmed up. It started a few days ago as ''fuzzy blue dots'' about the size of silver...

This was caused by a defect in the optical block of the TV. It will only get worse with time and the only way to fix it is to replace the whole optical block which is very expensive (over $1000 usually) and time consuming (you need to take the whole TV apart). However, since it was a defect, there was a class action lawsuit that caused Sony to extended the warranties for certain models on the optical block for parts and labor. Call Sony to see if your model was one of the ones they extended the warranty for.

Tv has little blue dots

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.

Blue haze/blue dots on hd tv

You likely have a bad optical block. Sony was supplying the optical block as a warranty repair until June of this year, but that warranty has expired.
