I have a Hitachi
Model# 43F300 42"
Well my problem is the green convergence grid are all wavy, on the top and bottom of the screen almost as if they are stretched. Can't line up any of the red or blue to the green.

Thanks in advance what should I do?

don't try to adjust the convergence... Change out the convergence ICs. It should require very little retuning/modification if you don't mess with the original settings.

I already messed with the settings but there is a mark on them to put them back, when you say change out the IC's do you mean just the one for the Green or one for each bulb. Any help with part#s would be appriciated and where to buy?

Thanks again in advance.

Here's what you want:

you'll need two of them. Replace them both at the same time.

Depends on how bad it is, Sometimes they take hours if they're real bad.
