LG	42LF20FR	It doesn't turn on, and sometimes it turns on and off, the stand by LED doesn't light up	Check main pci reset switch circuit	In my case it was capacitor c812, but it could also be the key, if it shorts out and sends 5v to the other side, thus locking the device	Ademar
LG	42PQ20R	When activating the power, the LED goes from red to blue, the blue LED stays on but the green LED does not sustain it. Tsound is a lack of VA and VS voltage. power supply maintains 5v but hits the relay and disables the rest.	Power supply pcb defect, changed q951(fqpf 9n25c) changed close to the ysus output connector. in this case without defects on ysus, 08/2023.	Hugs
LG	RAD114	Turns on, tsound is no sound.	Strw-6753 short on power line; changed ic901; q904(20v power supply); zener zd911; zd901; pc901 and d901	The above components were replaced; device ok,	Valdecir Schena
