LG	42LW5700	Doesn't start	TV arrived completely stopped, I checked that one of the fuses was not powered by one of them. Checking the tracks, I found oxidation practically imperceptible to the naked eye. I redid the track and the TV was fine.	Fix tracks with signs of oxidation	beto_eletrotec
LG	32LV300C	Doesn't start	Capacitor c918 burned and fb9101 open. check q9101.	If this does not solve the problem after replacing the components, the c.i 3s121 ref u9101 is defective.	CELSOKAYRAN
LG	32LY340C	Burning leds	Change the LEDs and remove R816 from the circuit to reduce the LED voltage to 108 volts	Replace the LEDs and remove R816 from the circuit to reduce the LED voltage to 108 volts	antonio nobrega (patos pb)
LG	42LD460	Turns on, lights up normally, turns off and turns on and off again 3 times, then turns off and the red LED flashes.	I observed c204 and c 219 puffed up. After repairs, the defect continued. I noticed "hissing" in the lamp transformers, t703 and t704. I noticed high voltage leakage at the lamp terminals. I dismantled the screen, turned it on, noticed a high leak, no spark marks on the bulbs. I assembled everything and found a defect on the power supply board. After checking, I found VR 301 changed, replaced it, problem solved.	Replace c204, 219, also replace c205 and vr301.	arock
LG	26LC7R	Image freezing/freezing/waterfall effect/horizontal bars or even no image	Display cofs are coming off. These are those golden flats that connect the glass to the screen plate. Looking at the original position, it is the first one from left to right.	Fit this flat with a heat dissipation rubber similar to the ones that go on plasma screens. It happens a lot on 26" Chimei displays, both on Samsung and LG.	PL Eletrônica
TV LG	42LY340C	Does not even turn on standby	In my case it was the main board	Just replace the main one and get the real one	eletrônica ressonante
LG	42PJ350	Alloy with dull image grainy image	607 resistor open.	Resolved.	Fernando rj
LG	29FS4RL	Turns on works, when turned off using the control, it only turns back on with great insistence.	Cause: zd827 shorted, replace or remove it and the TV works normally again		Eletrônica Santista
LG	32LP360	When plugging into the socket, the red LED flashes twice and no longer lights up, only to light up again after removing it and putting it back into the socket.	Two LEDs on the bars burned out, causing the power supply to go into protection.	In this case I replaced all the LEDs on the bars, even the ones that were still working, in a technical case I don't just have the original LEDs, changing the bars for new ones also solves the problem.
