Make	Model	Symptom	Problem	Solution	By
LG	LG32LE5300	No sound or no sound	In my case it was an open track near the sound output.		Luciano Fontes
LG	42LB6200	TV doesn't turn on	Transistor q601 (k10a60w) shorted	Replace the mosfet	Robson RJM
LG	50PN4500	Turns on, a very weak, drizzled image appears and the screen remains blank with only sound	D401 near 150uf x 250v capacitors		Sylvox
LG	32LM627BPSB	Doesn't start	Power supply ok. main voltages ok, shorted capacitor on the wifi module, disconnect wifi cable, if it works shorted capacitor defect		fabiusmax
LG	32LH35FD	It turns on normally but when you put the antenna in and the image appears, it locks and only comes back on if you unplug it.	Capacitor smd c829 330uf 16v	I put in a 470μF 16v electrolytic, just run for the hug. credits to the cate channel electronic technical support center. https://www.youtube.com/watch?v=htllqjbanbi	RYK
LG	49LF5400 SA.BWZYLJZ	The TV keeps blinking the stand-by LED and the backlight blinks at the same rate. From what I saw, one side shows that the backlight lights up when the backlight blinks and the other side doesn't seem to turn on when it blinks.	Credits to gl technical assistance, through the youtube link: https://www.youtube.com/watch?v=kxbjc4-znom	It explains very well that the fault is in the backlight and even shows that a ruler is leading to the TV ground, close to 20Ω and in my case it was that too, so diagnostics of the bus short circuit with the GND housing.	MIGUELTV
LG	42PX4RV-MC RF-052C	Bad image, blurring only on the HDMI input.	Check resistors from 22r position ar1200 to ar1205 above the hdmi circuit. measure all 22r lines individually, in my case I had only opened one line of the resistors.		rafaelmoraes99
LG	55LA9650	Doesn't start. power supply shorted.	Shorted components: ic501 ic3br4765jz, c502 47j. If, after the change, the power supply keeps the relay knocking, check the two cis l6599ad as one or both of them may have a short circuit. change components.		rafaelmoraes99
TV LG 49	40LJ5550	Black screen no video	Defective screen.	Turn off the flat on the right of the t com, if the voltages vhl and vgh appear, a defect is confirmed on the screen, put a 5mm tape on the flat on the right of the t com, count 5 tracks from left to right on the flat and put duct tape insulating about 8 tracks .
