Speakers only affect CRT's. This is an optical block issue.

Horizontal blue line at bottom of my screen, on my 60 inch lcd wega, was about 2 inches from bottom of tv now it's like 3 inches from bottom, blue line is about 2" high all the way from left to right...

The "optical block" is bad. There are currently 3 settled class actions against sony for other models with the same problem, If memory serves me correct, your model is in an ongoing class action. If you google Sony LCD class action suit. you will find lots of info. www, and support has a few articles as well. It is a 900.00 part, so, not really cost effective to repair. Post a comment for me tomorrow and I will paste what links I have on this issue to this post. There in my other PC at my office. Hope this helps

We purchased a sony wega hd lcd projection tv. The set had a great picture until the lamp had to be replaced. The screen got progressively darker until the screen went completely dark. After the lamp...

It sounds to me like you got a fingerprint on the lamp when you installed it. The oils in your skin can cause all kinds of problems on a lamp that gets soo hot. I recommend replacing the lamp again and using a tissue or sterile glove to hadle the new bulb. Also, before replacing the lamp make sure to clean and vacuum out the light engine box and fan.

If the problem persists, then the LCD panels inside the light engine have been heat damaged. There is a class action lawsuit in New York that is trying to extend the light engine warrantee on Wega TVs. You should give Sony a call at 1-800-222-SONY for information and more assistance.

good luck!

Problem with sony 60" rear projection TV

I'm afraid, it is problem of optical block unit (light engine) that produce picture by 3 lcds inbuilt, the blue lcd and its related uv filters become defective and causing this kind of blue hue on screen.
Complete optical unit block (light engine) will be replaced by qualified tech to get tv fixed, light engine is costly part so ask an estimate before sending tv in.

Sony Grand Wega KDFE 42 10 = blue streaking

I called a repair company who said it would cost about $1100. to replace the optical block. Sony offered no help or solution and the comment was "all electronics will have problems in 3 years". We will buy a replacement after researching what we want/need.
Thanks for your input.

Yellow brush marking on Screen

Your problem is with the blue color,maybe some dirt is sitting on the face of the blue crt and is being projected bigger to the screen,you should try cleaning the face of all 3 tubes,if you familiar with tv service this should help,be careful when removing the back and make sure the set is unplug when you do the cleaning.Let us know how it goes.
