LG	42LD420	Turns on and off (the lamps blink when the TV turns on)	Ic 301 que faz o back light ( bd927df )	Replaced the ic 301. the problem was solved.	DANGRA ELETRÔNICA - SÃO PAULO
LG	29CC9RL CW-62C	No sound and screen closing on the sides	Changing capacitors c 314, c 808 and c838	Resolved	TAVARES
LG	LM-U1350A	Very low sound replace strx6759 you can put strx6757 as long as it is original and with 4 terminals forward it is great	Strx6759 ou strx6757		robert
LG	LGD625	Does not turn on, secondary power supplys zero! without any intention! apparently normal primary, check the zd902 10v diode	In my case zd902 10v		DIM ELETRÔNICA
LG	55SM8600PSA	Doesn't connect at all.	Ic1700 burnt out.	Replace ic1700, it is the same as ic2100, smd 3208 regulator.	ZENER Serviço Técnico
LG	32LE5300	Does not tune channels, or tunes disappear after a while.	Defective main board, in the tuning circuit.	Smd ceramic capacitor c3006 shorted, interrupting power supply to the tuning block.	RNSPTEC
LG	32LK510BPLD	It gives no signal.	Shorted smd capacitor c5612, replace and run for the hug!	Replace c5612	NCTIC REPAIR
LG	32LV2500	Blinking standby tv won't turn on	Large capacitors at the sound output shorted.		Rivaldo
LG	32LK450	It turns on immediately and turns off or restarts, blacklight flashing as if tsound were bad bulbs.	Several cold welds were redone and the defect continued.	Replace capacitors in the power supply c510 and c509.	Hilário Luis Sperling
LG	22MA33D-PS	TV inoperative, nothing turned on!	Smd 716 capacitor, close to the speaker connector, shorted...after it was removed, the TV worked...replaced it with another		Williansbill
LG	14CB25	It came with a half-height vertical and did not memorize after updating the data	Rectifier diode d 22 and capacitor 100uf 10v c 40. on the EPROM side		JR Alagoinhas BA tec
LG	PA4500 PB 21A	Burning components	TV schematic for possible troubleshooting		Hernany
LG	M4214C-BAJ.AWZMLJZ	Does not turn on, fuse in the middle of the board is open and 2 diodes are shorted.	Replace of shorted diodes in position d502 and d503 close to the relay. put diode mur460 or larger.		rafaelmoraes99
LG	42PJ350	Does not tune channels	Replacing the 20r smd resistor r-643 which is close to the ic-602	On some devices it is under the glue on the hdmi connector	Pedrinho
LG	32LS3400	Connect the plug to the socket, the voltages are normal, it turns on and has audio but the screen does not light up.	The voltage 3.3v, 12v, 24v are normal, the voltage of the LEDs starts with 140v and drops to 24v.	Check the LED bars, one of them may be defective, a burnt out LED, replace it and it will be normal.	Eronaldo (erontec)
LG	32PC5RV	Turns on, but the power supply mosfets q602 and q603 were getting very hot until they burned out in 20 minutes	Shorted diode and open resistors	Replace d603 r602 and r603	LOOPTEL
LG	22MA33N-PS	Doesn't turn on anything, no stand-by. It has almost all voltages, but it lacks 12v for the dipslay.	Bga	Reballing lge2121, solved it the first time, before stopping turning on the TV it showed artifacts in the image etc. With this we went straight to reballing.
LG	21FS4-RLG	Buzzing, hissing (particularly low, but audible)	Possibly the problem is on the kinescope board, possible cold soldering and poor contact in the sockets	In order of priority; dismantle the socket from the tube, clean it to eliminate any oxidation or dirt, redo the cable that comes from the flyback to the socket (cut/eliminate and strip, only the part that is inserted into the socket), finally check the welds on the board to the look for any cold welds.

LG	20CD2R-LD MC-059A	Reduced vertical, +/- one finger at the bottom and top, in service mode had no effect	All voltages were ok, after a lot of trouble, I found the r303 changed to 9 homes replaced i	Thank God it was perfect, go for the hug	G.G eletronica
