Make	Model	Symptom	Problem	Solution	By
LG	32LD420	Turns on standby, does not turn on the lamps	Main board shorted on the processor, reballing solved the problem.		lojas trovarelli
LG	32LH570B LA66K	Doesn't start at all	C5608 in Kurdish	Replace it	MARCELIO DREISSIG
LG	21FJ8RL	Horizontally turned, i.e. image lying down (like bars)	Altered 22k 512 resistor	Replace r 512	ON-PLAY ELETRONICA
LG	RP-20CB20A	Very low and hoarse sound you can only hear at maximum volume as if it were memory	Resistor (r625) de 22k	Replace for the same value	Eletrônica Bastos
LG	32LV3700	TV turns on normally, red LED turns blue, but no image and no sound	In my case it was cold soldering on the BGA (processor) on the main board	I took the plate to the oven at 200ºC for 10 minutes, preheated for 1 minute beforehand, let the plate cool, assembled it, put a cooler on it and the TV has been working normally for over 1 month, the TV is mine, not a customer's.

LG	RP14CB20A	Image without horizontal synchronism, the image is colored in the form of sea air in the av and rf	Defect near ic501, changed resistor 4k7 just change the image normalized both av and rf	Resolved	Carlos
LG	RP14CB20A	Image without horizontal synchronization, both and the shower effect	Close to the ic501 - lg631 9r, to a resistor position r512 - 4k7 1/8w miniature it is leaking, I measured in the digital test that the 4k7 is giving 5k1 it is changed, I changed it resolved the image was normalized it was ok in both the av and rf	Defect resolved	andre
LG	29FE8RL	Turns off after a few minutes.	Replace resistor r843 220k	Replace resistor r843 220k	DJ PITUKA
LG	42PJ350	Has audio and no image	Check buffer board or oxidized t-501	Resolved	JORGE ASSISTENCIA TECNICA
LG	CM4320	Turns on without sound and without the red LEDs on the edge of the volume turned off and then turns off	Q-953 with leak	The replace of que-953 for bd135.	naldo oliveira
LG	LT27B350LBMZD	Doesn't start. standby LED flashes twice in a loop.	Schottky diode sr5100, position dm851. As it works in parallel with the dm852, I decided to replace both. Once this was done, the TV started working normally again. Hugs to everyone and don't forget to send your repair tips, it helps a lot!!!		AnisioH
LG	26L30R	Lamps don't turn on	F 1 an ap looks like a resistor has the number 20 on it note it is on the iverte plate		SALES ELERONICA
LG	32SL5700	It doesn't turn on, it doesn't even light up	Testing the power supply secondary diodes (d251 to d254), they all had a short, when removing the connector that goes to the motherboard the short disappeared... in other words, a short on the motherboard..	C5422 short (close to the audio output ci)	Maurilio
LG	22MA33D-PS	Inoperative TV won't turn on, plus normal 19v power supply	Capacitor c803 shorted, causing ci 809 to burn, it is close to the flet that goes to the display.	Ci 809 and mp158 must have 24v at the output, the capacitor c803 can put 4m7 63v smd	guinga sdia goias
LG	47LM6210 6200 6230	It does not tune digitally, but analogue tunes normally.	Voltage +1.23v_d_demod (low voltage, 0.50v) that goes to the tuner pin 30. this voltage is provided by the ic6501 ap2132mp-2.5trg1. This ic is close to the tuner	Replace ic6501 and it worked, it worked perfectly and the voltage 1.23 appeared normal.	MIGUELTV
LG	LV3700	TV doesn't turn on, LEDs don't light up, standby lights up dimly. damaged main board	Reflow the processor and nand memory. put a good amount of liquid flux underneath.		Rmseletronica
LG	32LH515B EAX67026901 LJ67A	TV completely inoperative	Ic500 mp3378 burned	After the replacement, the TV started working perfectly again, remembering that the component code is mp3378, because if you search for the code above you won't find this component anywsound, it is already for sale on the open market	marco antonio
LG	32LB9RTA	No audio, no sound	Hdmi ci shorting the 3.4v	3.4v low, around 1.0v, beeping the capacitor tsound was a short, disconnecting the power supply board from the main board the short disappeared, we found 2 smd capacitors with a short on the back of the board, close to the plug that connects to the power supply , we put a voltage of 5v on them and the hdmi ci heated up, we removed the ci and the audio came out perfect. partial solution = remove the ci, however you will be without the hdmi function. total solution = replace the hdmi ci.
