Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine.

Do you mean KF60WE655. I don't recognize the model you show. I'm sure your talking about an LCD rear projection Sony. Your trouble is in the Optics ( light engine). Over time the Lamp has destroyed an internal filter ( glass element ) . This Blue haze or film will probably continue to get worse and grow across the entire screen. The only fix is to pull out the Optics and send off to Sony or another re builder.
Up until June 30, 2008 some of these models were being fixed at no cost by Sony.

You have a problem within the light engine. This a hugely expensive. If the set is not too old you could contact Sony and see if they will help you out. Otherwise it is not eceonomical to repair

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.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. 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.

Solution #2


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

if you have any speakers near the screen the magnet may be causing the problem. i had a similar thing happen & when i moved the speaker the problem went away

That could only be the optical block, Sony p/n# A1084662a and heaven help you if it needs to be replaced. It is the single most expensive part of the DLP based projection Tv's costing approximately $900.00 dollars plus core and shipping..
You'll need to take this one to a quality repair center to have it estimated. It may be that they can repair it also - but whatever the case these type of repairs are not cheap.
Please don't kill the messenger...
Good Luck!
