Make sure your yoke plugs are clean and no cold solder joints around them. Let me know? Do you have a scope?

    Double check all the solder connections on the STK's again. I will check to see if you have a DCM module in that model and let you know.

I have a panasonic 47" widescreen about 5 years old. Recently turned it on and all 4 corners are missed aligned and a faint line going through the middle. Tried setting the convergence with all of them...


Yes, the convergence output IC's have gone bad. They need to be replaced. This is a very common problem with all projection tv's. It is the job of those outputs to properly align where the red, green and blue beams land on the screen.

Convergence problem not fixed after replacing STKs


I found the chips easy to replace, but time-comsuming due to the number of pins involved. I woudn't want to try it if I'd not had prior experience with soldering.

Still no response to the original question though. With 2 replaced STK392s, red is still not moving in horizontal alignment. What gives?

You are on the right track. The problem is actually with the green convergence IC that controls the alignment. The convergence ic's take the information from the 3 pictures and align them into one picture on the back of your screen. Although this is an economical repair it is complicated and should be left to a quailfied service technician. If you are not sure of a local technician, panasonic's website has a servicer locator that can guide you to one. Hope this helps

One of the resistors in the circuit connected to one of the ic's has burned out or changed value due to heat caused by short in previous ic before it was changed.
