Mits 46805 - replaced IC's - picture now too Dim.

Having a problem with a Mitsubishi wt-46805 - I'm trying to fix my
father's TV that developed convergence issues. I replaced the
STK392-040 IC's with new ones from Acme and it fixed the convergence
issue, however now the picture is really dim.

The picture seems to be dimmer on the right side of the screen, but
it's like looking at a 20 year old tube set, just unwatchable. If I
activate the "iris" feature the picture goes completely black.

I ohm'd out the resistors leading from the IC's and they are all within
spec. Is it possible that I've got bad IC's? Can this cause a dim
picture? I'd appreciate any suggestions on what else I should be
looking for?

Thanks in advance.
