Take the speaker grill off the front, in the center there is a thin plyboard, unscrew it, down on the bottom there is 6 adjusting screws X X X X X X B G R I simply turned the screw, (the 3 screws on the bottom, the 3 on top are for focus) just a little counter clockwise marked B and G, that was the 2 color curved lines I had on my tv, this fixed the problem, not my idea I read this on another person with the same problem.

Loss of B+,look for open pico fuse. Recheck both pcb's.NEVER trust a rebuilder. ALWAYS try to fix the board yourself.Ask for pro advice,if needed.

I have a kp57hw40 sony tv and the scren it flashs


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. This is called convergence.

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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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 - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

The colors are distorted and there is triple images


Hi,
triple images show failure of convergence out ICs in TV, these are two big black ICs mounted with aluminum heat sink on D board, replace these ICs with same number STK392-560 and problem in your Sony KP-46WT510 will be solved.
Required ICs are available in Part Store.
Let me know any further question, if any.
Thanks.

Cannot converge colors on screen


This happens when convergence out ICs become defective.
Replace convergence ICs on D board to get correct picture. This qualified TV tech job.
Thanks.

Convergence Issues


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 its the color won't align its the convergence board. First you could look for bad resistors and or capacitors
