SOURCE: Sony rear projestion TV has blurry picture.

sounds as if your convergence needs to be set. either through the menu on the tv or remote you need to get to the convergence set screen and you need to line up the crosshairs. this usually happens when the tv is moved or bumped.

SOURCE: Sony KP51WS500 Rear Projection TV,Convergence Problem

Your TV most likely has one of two 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 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.

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 a CONVERGENCE problem and it will not adjust---the two STK-392-150 Chips this set uses need to both be replaced and the set adjusted with the original remote control.

You can, if you are able to do the repair, buy a pair of chips for less than 14 dollars plus shipping on Ebay.

If you cannot do the repair--shop around your area--most shops are going to charge 300 or more for this kind of repair.

When you consider the cost of the parts--if you can do it or know someone who can--you can save the set and a lot of money--This repair can easily be done right in your home in about 1 hour--I know as I have done hundreds of them---did two today.

The chips (with the back off of the set) should be on two metal heat sinks on the board on the far left---they will be facing the front of the set.

All that is required to get at them is to remove all the plugs on that board and the screws that hold it in and tilt it up so the bottom of the board is in view---you unsolder both chips (about 18 pins each) and remove the 2 screws that hold each to a heat sink.

With 2 new chips you put heat sink compound on the back of each--it is a white grease to move heat quickly from the chip to the metal, and solder both chips in----put the board back down and all the plugs back(I usually mark all of them so I know where they go) and turn the set on and see what you have...

Most of the time this repairs the set--go into the customer menu and adjust the convergence and you are ready for another 5-8 years of life---this is the normal lifespan of these chips.

Thats caused by a convergence failure. The Sony type 1 convergence repair kit from www.tvrepairworld.com will usually correct that issue the kit contains the components and the CD with repair instructions so you can repair yourself.

The colors are separated. Images are blurry and


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!
