Convergence diagnosis

I've been searching for information on a convergence issue that suddenly appeared on my TV (a Panasonic PT-56WX52CF) but haven't found a definitive answer.

Symptoms:
Issued appeared suddenly with no adjusting or moving of the TV
Picture is good on the left side of the screen but gets progressively worse to the right
Red is shifted horizontally to the right
Green is shifted horizontally to the left
Convergence controls seem to work


From what I've read, this may not be the convergence chips.
Any thoughts?

Looking for me, just google my username. I have used the same one for most sites for many years.

Re: Convergence diagnosis

Please read the first ten posts of the convergence repair sticky in the DIY Repair forum VERY carefully.

If the convergence can be adjusted in both directions on all three colors, you likely have working chips. What you describe sounds like a linearity problem.
