    same problem really sucks

    I have same issue. Repair folks want $350+. If parts are under $100, this beats the repair shop estimate. If the set was purchased in Jan 2003, how much longer *should* the set last? How many years does the set typically last? When looking inside for Conv. IC number (STK392-560) I cleaned the dust off the tops of the three guns. Now picture is a lot brighter.

You have a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
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<<<<
You need to replace the convergence chips and convergence resistors.
Check the site www.TvRepairKits.com

They have put together a kit for your exact model.

The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

This type of convergence problem is not likely to be fixed by the autoconvergence procedure outlined in the manual. Either the connections at the convergence ICs are defective or the ICs themselves are defective. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself. Please update this if you wish to attempt the repair. The parts cost will be between $25-$50 total.

Thanks,
Dan

On left half of the screen [ KP51WS510 ], a redish shadow showing


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Colors arched and overlapping


if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

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.
