Having green and pink lines on the bottom and curving in the middle of the tv. What do you suggest for the fix?

If you cannot align RED, BLUE, or Green your TV has a convergence failure. You can see some more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

This set has a convergence problem. You should only need to replace the IC. Part is STK393-110. It sits on the middle board behind the large heatsink. Use a heat transfer compound to ensure repair lasts. If you have no experience soldering (or unsoldering) please use a professional for the work. The traces are fragile and I have fixed many mistakes local DIYers have committed. Goodluck.

need replace conv.IC:stk392-570.good luck.

Its your receiver, not your tv! Switch receivers and it will go away!

There are problems in the vertical blanking or scanning circuits. This is not something you can fix yourself at home. It involves troubleshooting the deflection amplifiers and scan generator areas to locate the defective components.

You will have to give the set out for service. I would suggest to get an estimate before proceeding. This type of repair can be costly for the labor to find the fault. If it is only generic type parts involved, the parts themselves will not be too expensive.

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

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• 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.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

I think you might have a convergeance problem, check this out.

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.

 

I hope this helps,

 

Thank you,

you can get it your tv fix the problem is in the IF amp and video circuit.a convergence will also be neeeded.the tv is old but can give you some more life call a tech they will be your tv doc.
