Pioneer SD-P4565 convergence problem	Can't Post

I recently recieved a pioneer 52" projection TV for free, because, well, it has issues. The screen would bounce some, which turned out to be a simple dirty potentiometer , the one that adjusts picture width. The problem I am having now is with the convergence. Please bear with me, I have never adjusted a projection TV before. I did find out how to get into the convergence menu, but it only allows you to adjust the red and blue guns. The green one is what really needs to be adjusted. At the bottom of the screen the green is fine, but it stretches upwards in the top corners. There is a smooth arc across the top of the screen, and its only green. I can cover the green lens, and get the red and blue to line up correctly, just not the green. Is there some hidden adjustment for this, or is it something wrong with the TV?

When the Gods designed projection set they needed a refrance for all colors to line to some one desided Green ( Makes sence since most of the color in sets is green, ) It is usaly non adjustable by the custmer,, , If you have convergance issues and the culpret is a Pioneer ( since we dont have a model number to work wit well cover all of them,

1st one behind the speaker grill behind the panel there is a board it has one huge Ic STK4277 change that

2nd with the back removed there may be a board on the left that stand up, on this there may be Two Ic's ( STK392-110) or there may be three ( STK392-010) chang all of these

there may be two or three Ic mounted to the left ( Signal ) board STK--- change those

always change all at the same time heres why

if theres ony two they share the greens convergance, if theres three they only do one color each but they all wear at the same rate if ons gone usaly the others are right behind it
