Convergence Cirvuit Board - Ripped Tracks JVC AV-56WP30

Ur tv have a problems known as a convergence problems,it dead.The tv have colors lines R,B,G mis alignments,have colors shadows pictures or 3D picture look alike?The tv convergence board it is dead.The tv convergence board,must require repalcing 2 STK convergence ICS and some or all of it resistors too.The tv convergence board is fix,will solved ur tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

the --ic --has not been fitted properly.

If auto convergence does not work in the menu then replace the convergence ICs and check resistors around it. You can take the grill off the front and access the convergence board fron the front. Its a small board to the right and it is removable. Do auto convergence again after replacement.

Yes,This problems happen,must replaced all IC chips and all the resistors.

I got the correct answer from another free service, I can't afford your paid service and listed below is the only answer that I received from you for free:

Hi

You have defective convergence correction amplifier IC replace the STK IC...

Thanks!

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.

check your soldering and make sure all the pins are soldered and you don't have any solder bridges.
have you checked the resisters?

Remove front grill cover---look just inside--If your model has the
convergence board up front,then you might change the board
instead of re-building it.Depends on price and availibilty.....

If you want to pursue repair,let me know......T.
