NO... More than likely, It is an optical block problem. Sony has had this issue on Many models!!

And has had several Class Actions mediated. I'm not sure if yours has settled yet. http://sites.google.com/site/sonylcdrptvproblems/

Check that link and then contact Sony Customer support. They are actually pretty easy to talk to regarding this issue. Hope this helps!

Little blue dots on screen and large blue haze in upper left corn


Sounds like the light engine is going bad...that's why they stopped making these rear projection sets using LCD's. Costs almost as much as a new set! But get a second opinion before trashing it.

We are starting to get some blue light glowing on the screen


Good Day,
Your Optical Engine is going bad. Call a Sony Authorized Service Center. Most are covered even beyond the warranty period.

Good Luck, BIG IRISH.

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.

Blue haze and dull yellow patches on screen


The light engine in your set has gone belly up. It is a very expensive repair. Good news is that on a whole bunch of models like yours Sony has extended the waranty on the light engine. Check with a local authorized Sony service center and give them the model & serial number and you might get a free ride. If I were a betting man I'd take odds on 'you're in luck'. LOL

Blue haze in picture


Sorry guys the news is not good. The Optics or light engine must be changed or rebuilt. The lamp has destroyed a filter (glass element) inside. You must remove the optics and send it out to be rebuilt. Not a do it yourself type repair.

Blue haze consuming my sony grand wega


It is definitely a bad optical block. Sony was offering an optical block replacement under warranty until June of this year, but it has ended now. Ballpark estimate is $700 to $1000 to have the optical block replaced.

I am getting a blue spot on my tv screen


Go to the SONY website and look for the blue spot repair option. They are repairing this for free if you purchased your set within a certain timeframe. They repaired ours- it would have cost $900.00 for the part alone. It works great now. The tech said to vacuum the back every week to try and prevent this from recurring. The offer ends in December- so hurry-
