Thanks to all that responded, I must not have been clear -- the convergence was bad-now is ok with new chips, second problem is now good pix and convergence-but has three large curved lines in the top 1/3 of pix.-- these three curved lines are on top of the regular picture--one line is red, one blue, and one green! problem is in the video, video out from output jack on set is normal-no lines. Problem shows up with antenna input video and external video inputs. Pix is Ok with input into component jacks with HD signal. I think problem is caused in the PIP module as video looks ok going to PIP module, but not ok on screen of TV. HD reception does not go through the PIP unit so is good. I plan to do the old bypass trick tomorrow of the PIP mod. as we do in the older Mitsubishi PTVs. Not sure what to bypass so will just try caps from input to output pins on PIP with PIP unit removed from set. Customer says he never uses the PIP and does not want to pay to get the PIP fixed. Will post results if/when I figure this out.
