You have two convergence amps that need to be replaced on the convergence board.This is a very common problem with these units.The part # are STK392-110 but I would upgrade to a STK392-120 or a STK392-150.Also there may be a couple of low ohm resistors that need replacing.Depending on your electronics experience this job is pretty much a straight forward soldering job that requires a certain amount of knowlege.These parts can be obtained from partsstore.com.I as a technician charge between$185.00 in shop and $250.00 inhome for this repair.It is well worth it as this particular chassis really did`nt hve very many problems, and once fixed you will have a like new picture.Good luck!

    I agree with Ronnieh49 you do get a lot of diffrent answers that can make your problem confusing,but I also beleive that if I`m going to give advice on something that I do day in and day out for the last 20 years ,I`m going to make sure that the information I give is the best that it can be.It`s a waste of your time and my time to give false information and I make it a point to avoid such situations.95% of the JVC projection TV with this chassis that I work on require the parts I indicated.When I take a call as such these are the parts I take with me.The only other fix I know of for this set is.. Go into the Menu and select "Convergence" select the option reset and reset.If this does not correct the problem you need the amps replaced.This is a very common problem and as I stated it is a very detailed soldering job.Call your local repair shops and share this information with them.Any repair shop in buisness can only make money if they fix the problem and.you have to agree that the price is fair.Good luck!

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.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

  • One or more colors can't be adjusted when using the convergence menu.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Convergence


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
