Default Re: Panasonic TC-P65ST50 plasma in protection mode after incident

R414 is not the source resistor it is just a fusible resistor in the supply voltage line. The source resistor is R403, I would check that resistor and the diode D411, If the ic shorted, D411 may have shorted and now R403 would be bypassed by a shorted diode. With pin 2, S/OCP connected directly to ground and not through the resistor, the ic can't monitor the current.
I should add that having a lower resistance for R414 should not have caused a problem.
