Goodmans11ak37it will not come out of standby, power light pulsing. i've managed to get the set to turn on by disconecting the standby from ic501 pin 47 but the set starts to make a squealing noise. Replace power supply controller ic MC44608P40 (ic800). It's often dead. And check line output transistor.28-11-05
