    I have a green swirl at the top of the screen with some double imaging. Is it worth the $$ to fix?

  • munky_350 Oct 17, 2008

    Yeah, it looks like green saggy lines and swirls at top of screen, and is doubling up picture... If anyone ever finds a fix, let me know. Thanks.

How do i find out if sony kp/57ws510 picture tube is bad


While the set is prone to bad tubes a double or 3d like image is convergence--this model uses two of the STK-392-560 CHIPS for this.

Go into customer menu and call up convergence--if off and will not adjust in any area of the screen the chips are bad.

I HAVE A DOUBLE VISION, BETWEEN THE GREEN AND RED, THE GREEN IS SOMEWHAT WARPED OR ARCHED.


Hi,
Please run the convergence feature on your TV. Its giving you double image because the red, green, and blue guns are disaligned. By running convergence it will realign the guns properly. You need to run the convergence feature at least once a week. Please note this is only for CRT rear projection TV's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to. Please refer to your TV's manual on how to do convergence and how to overlap the crosses because every CRT projection TV is different.
Good luck!

Double picture & color problem


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,Akai2_bing.gif,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

Thew picture is double vision and orange and green. Is this the picture tube?


The red and blue convergence ICs are bad. Probably only the red one is bad, but you should change both to be sure the other doesn't go out the following week. Go to tritronicsinc.com for the the replacement chips. The chips should be installed by someone with soldering experience as they have about 20 pins each.

Pincushion Picture on a big TV screen!!!


The set has 3 IC's(one for each color)strictly dedicated for the aligment of each color,if one them does not align is because is going bad or is already bad becuase picture can not be adjusted,the IC's can be identify because they are mounted on a heat sink and have the markings STK--- ---,they are all the same and need to be replaced with an exact replacement.If you are familiar with tv service you can replace them,sometimes the new ones need to be aligned from the service menu,you will need the service manual,soldering and unsoldering will be involved,If you are not too familiar be safe and seek the assistance of a servicer.
