Hi,
I've got faulty LG 50PM670S plasma (Manufactured December 2012) for free from my friend. Symptoms are red Standby light is on, when press remote controller power button it goes off for few seconds and red Standby light goes again red.

Opened case and removed dust from inside and trying find what card is broken, when Y sus board is not connected TV start ok and Standby light stays off when press power button.

Checked Y sus board and found 2 shorted IGBTs and 1 shorted mosfet.

Replacement parts needed:

Q404: 30F126: Transistor N-IGBT without diode 330V 30A 18W, TO-220F TOSHIBA

Q509: KF7N60F: N CHANNEL MOS FIELD EFFECT VDSS 600V VGSS +-30V TC=25 7A Pulsed 20A DPD 41W

Q403: 30F126: Transistor N-IGBT without diode 330V 30A 18W, TO-220F

D402: SF20A300H: 300V, 20A ULTRAFAST DUAL RECTIFIERS TO-220F-3L (unsoldered that and need replaced also because its legs..)

But I don't find these parts anywhere only from China. Items doesn't arrive from China due coronavirus that I can't order from there.

Does anyone know replacement/substitute for these components what are available from Europe? I living in Finland..

Did you get the spare parts for the TV. I'm in the same position! 2 BAD IBGTs - Identical symtoms
