philips ic convergence problem help


I got a Philips 46pp9302 projection TV. I believe the chassis is DPTV33 0.
My convergence was way off, so I replaced the ic’s stk392-120. I put it all back together and the results were the same. The blue looks ok. The red, I can move the convergence up – down, the right/left does not work.

I ran the TV for 30min trying to adjust the convergence. When it didn’t work I took the temperature of the ic’s with an inferred heat gun. The ic closest to the end of the board was 134 degrees F. the one closest to the middle was running 10 degrees F less. This seemed to be constant as it warmed up.

From a different site I was told to look at resistors 3157 and 3158. I looked at them and with the board out; I put the old multi-meter on them. Both resistors read 3.9 ohms. So I checked all the same resistors in the area (3149-3160). They all read 3.9 ohms. Resistor 3153 and 3154 had no readings. I am thinking that these might be the culprits. But these resistors physically look different. Why? I checked the color code; it looks like they should be 3 ohms +-5%. I am tentative to replace these two just because they are different from the others. Am I missing something here? The TV was bought new and never been repaired. It seems odd that the factory would switch resistors in the middle of the board. Does it seem that I should replace those two? It was also odd that they were placed in opposite directions. I thought in resistors it didn’t matter?

If I replace the two resistors, do I have to buy 2 new ic’s?

I also checked the big stand off resistors in the area. They all read 100.1 to 101.1 ohms.
Can anyone help me in what my next step should be?
Thank you in advance,
kuby
