[TV] Re: philips 55pp9401 blue horizontal linearity problem
You likely have a low ohm resistor located near the STK's that is open. More than one of them may be bad. You have to disconnect the convergence yokes before you measure them or you will get a false reading. Since you have cleared the DCU you will have to do a complete reconvergence and you will need a template to do this properly. The convergence can be done without a template but it is very difficult to get the convergence adjusted so that the auto convergence will work. Also without a template you will likely increase your adjustment time from 3-4 hours to 2 or 3 times that long.

This set will not adjust the blue lin on the left side. I cleared the
dcu data which states in the manual it then has no dcu correction now.
Still is non linear on the left side. I replaced both stk chips 2 times
with new and checked the low ohm resistors. Could it be the convergence
yoke coil? I did use a inductance meter and the all check very close.
