Dan, Check carefully for coolant leaks... I checked Mitsubishi site and nothing on top/bottom pin problems.

Hi Fellow Techs, I'm working on Mitsubishi VS-50VA1 PTV (VZ-1 Chassis) which has a consistent slight bow in the top & bottom of the picture (pincushion) and has a line pulling up about 4" from bottom of picture intermittently this line will appear and disappear, best way to describe line is like a vert retrace line but a little different because it affects pincushion as it pulls up screen intermittently about 4" from bottom. Even when line disappears the bow at top/bottom is always there. I replaced both STK391-020 Convergence IC's and checked all resistors related to IC's (none smoked - all ok) checked many caps and reworked all CSJ's (Cold solder connections) I even checked C7001 and C7036 on PIP module. Sometimes the entire picture will go out and come back in. Set was moved from Texas to N. Carolina and customer stated problem started after move. I'm lost on this set. I've checked my WinsTips/ESD/Intrepid/TechAssist&archives/Goggle_search tips & more databases, I'm stumped! Any Help!!
