Make	Model	Symptom	Problem	Solution	By
LG	42LG80FD	LED flashes blue and red	Voltage varying	Boot q203	FRANCISCO FERREIRA
LG	CM-4320 G-10 F-5	Turns on without sound, everything works, but turns off after + or - 3 minutes.	Diodo zener zd-904 de 10v	Measuring on the plate, low scale, it measures good, but outside the plate, on the high scale, it measures short.	Pedrinho
LG	50PT250B	Image flickering, fading and drizzling after warming up	When opening the lid, it was found that the boards with the power components (power supply, ysus and zsus) were showing signs of overheating and tsound were many cold solders.	Resolders were carried out on the three plates. Some components such as resistors of more than 2W had to be removed, the terminals scraped to get solder. resolder everything.	Pixel Assist
LG	32LD840	Does not light lamps	C220 and c210 na plaque from power supply	Place cap. 1000μF/50 not place two 680μF	Eletrônica do Alemão

LG	42PQ30R	No image but normal sound	Checked all voltages of va, vs, 5v everything ok, except the voltage of vy which is shown as 17v	2r2 3 watt resistor identified open and with cold soldering, this resistor next to the yellow transformer next to the tp (-vy), replaced and it worked immediately. Note: measure the insulation voltages vs with gnd, va with gnd and vscan + gnd	CDS_DIAS
LG	22LG30R	Flashes 2x blue LED oscillates voltage 5vts	D102	Replace without measuring d102	presto eletrônica
LG	42PQ30R	Image with horizontal band and appearing to lack RF signal	Defect in ysus r729 (2r2) open (between trimpots vr401 and vr601)		eletmoraes
LG	26LD330	Doesn't start	Side keys leak when disconnected from the main board, remote control works again.	Replace or clean the key that has a problem.	dudutekk
