    A similar problem, except that mine spread down and across half the screen. I also notice that the screen is not totally black where black is being projected...the whole screen seems to be picking up a low level of scattered light that does not allow the black and reduces the contrast. I also see what appeared to be 4-5 blue dots scattered around near the center of the screen and they have now multiplied to about 12.

Although you have not posted a picture, I believe you may have a screen or LCD panel problem, the panels have film connections that go from the t-con module, through the panel control pc boards then through thinn film connectors from the lcd screen. Likely this is the problem.

The tv picture looks like should be wachting it whith 3d glasse

This is a very common failure on Projection TV sets. Its called a convergence failure. Here are some common symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around objects on the screen.

You can see some example photos and find a solution here on Fixya.

Cloud like image around edges of screen

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from that includes replacement coolant, photos. instructions, etc.

Vertical line on side of LCD TV

Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!

Sony KDF-42WE655 (LCD 42 inch)

I have the exact same problem with my 42" LCD HDTV. When I called Sony "customer support" they told me NOTHING. However, I began researching this issue and found out that Sony knows all about this problem. It's a part called the "Optical Block" and THEY are supposed to reimburse you for the repair! The claim form is on the Sony Website. Here's the link: Look inside the yellow box on the right and click on: Additional service coverage information for your TV (scribble / line pattern on screen) Hope this helps you!!
