Good Day;

It sounds like you have bad connection on the convergence IC's. They are, from back,on the right side, they are mounted on a large heat sink, silver/gray in color. Re solder the pins of those IC's. Be careful the pins are really close together. Fix it now or the parts will fail and will have to be replaced.

Good Luck.

Hi there, this seems to be a classic case of bad or broken connections in the convergence circuit. there are a couple [2] convergence output ics on large heatsinks near the center of the main chassis, usually soldering the connections fixes this, but due to the nature of the make-and-break of the connections the ics may have been damaged so i usually replace them to avoid a call-back, generic numbers are usually STK391-110 for standard definition and STK391-570 for high definition. The actual part numbers and locations may vary from model to model and year to year, but these are the most common. good luck and be safe.

There is a convergence output kit for this set. There are probably resistors in the convergence circuit that are starting to loose there values. If you are going to have the set worked on have them install the whole kit which includes the convergence outputs and resistors. Thanks

Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

  • This is a very common failure on Projection TV sets.
  • 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 PROBLEM


This could be the start of convergence problems. Anytime you are dealing with color lines then is the convergence. No first you could check for loose connection and then change in value return resistor in the convergence area. Hope this helps!
