Correct, TP63.Thx, its normal now. Not exact center but it isnt drifting. İ have an another problem, RT and LT both full throttling now. I didnt understand why. I broke Tp63, and i soldered LSY direct to the cpu pin but now Lt and Rt gone.
Check and make sure L1 is on the board first. The POK signal comes from pin 9 on J1. Make sure R7 is good, it's 0ohms, just a jumper but if it's missing or damaged it'll never get the POK signal to stay on. You should have continuity from pin 9 to D26, then make sure D26 is good.
LB to TP19 can not open/close fine, as those two spots should be connected. LB to ground should measure open then short when the button is pressed.TP19 to ground should do the same.Pin 6 to ground should also do the same.On a working controller that is. If you have the first 2 of those measuring correctly, but the third one is where it's failing, then the issue is either at the via for TP19 on the top side of the board, the trace from that via to the via right under where it's marked EG2, or the via/trace at bottom/left corner of U4. You'll need to peel up the top of the D-pad about 1/4 of the way to follow the LB trace. It's easiest to follow from the via under EG2, and it's the trace closest to the top of the octagon opening there. You can measure from that via at EG2 to the top of D1 to check the trace.
