If picture gets 3d etc, it is convergence problem.

See attached typical photos.

The model indicated uses two of the STK-392-570 chips for this and total parts cost will be under 25 dollars to fix set.

I also have start to finish, step by step instructions for this repair in this model.

If the information or the photos told you something you did not know rate this solution as very helpful as I do this here for free.

No two sets with convergence problem will look exactly the same but you will know if you have the same trouble.

Ws-55819 has code 22. It will power off within seconds.


Error code 22 on this model is most freguently a problem with convergence. Error code 21 is usualy the DM module.

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

Convergece 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 images of convergence problems.

Problem with 480i


 This problem has been around for awhile.

 The 2HDW PCB needs to be replaced. Part number 935C966001. It sits on the signal board underneath a metal shield.

 Not a bad repair and remember to unplug the set if you are going to do it yourself.

 Respond to this post if you have any questions and I will reply.

Convergence - bow problem


If you know how to solder on a solid state pruinted circuit board, try to first resolder the convergence IC's. There are two of them, they are black and stand up on a metal heat sink. The IC's will start with stk and have some numbers following that. Sometimes you can get away with resoldering BUT most of the time they have to be replaced. Consult a trained service person if you dont have any TV repair experience as thei like I said is a solisd state set and trhere are really no user replaceable parts inside of them.
