My picture was bowed and 3-d. I could fix blue and red convergence but green horizontal wouldnt move on the botton. So i changed its ICs chips. When i turned it back on again, i was able to fix green but couldnt fix red and blue vertical lines on the right and left side.... so it was still messed up, bowed and now the 3-d couldnt be fixed. I didnt change the resistors coz they looked fine, should i test them? They dont seen burned. I looked close to the IC pins and saw that some heat sink was touching a couple of them, is it bad? Shall i buy new ICs?
After the IC replacement, convergence adjustments should be done. If you wish to get some details; visit the site linked here. Pull up older posts.

You can find a replacement auto convergence board for a model # 55PP9502 from this major Philips part distributor at the following link:
Philips 55PP9502 Replacement Part Auto Convergence Board
SOURCE: red convergence is screwy
Try different IC's. And/or replace resistors. I had the same issue and replacing the IC's worked. Although I skipped the resistors, now the red alignment drifts nightly. I'm going to replace the resistors tonight to see if that helps.
SOURCE: convergence bad
resistor along the convergence are 2Watt size or less. they are easy to find as all of them are in pairs. if you find one is not the same on the other, then replace that resistor. change the 2 convergence IC at the same time. let us know.
SOURCE: colors shadowing eachother, adj convergence, but will not save.
Sounds like your convergence IC chips have failed. You can buy the parts from various suppliers or you can just get a complete repair kit from www.TvRepairKits.com
SOURCE: my red convergence won't move side to side only up and down
Most of these Philips sets use two STK-392-120 convergence IC chips; if you can locate them inside look at all the little blue resistors to the left and front of them---these are feedback (protect) parts---if any of them are discolored in the middle--not powder blue but somewhat white in the middle---you have a bad ic and both need to be replaced---most of the protect resistors are 6.8 ohm in value. If this has been helpful give me a vote.
