LG	47LG60FR LP81A	Blurred image shaking vertical	This TV arrived in my workshop with the following defect, it turns on a blurry color image, shaking vertically, I changed the flat display cable, nothing, I already changed the t-con, nothing and the lvds cable from the t-con goes to the main cable, nothing solved, resolve to remove the ic1000- tw9910dana2-gr decoder video I turned it on without this IC the image was normalized the IC is shorted I removed it from another board	Image resolved	Andre
LG	47LG60FR LP81A	I'm sound	Ic 600 ntp3000a short, just replace	Resolved	Andre
LG	49LF5410	Backlight blinking in some cases TV won't even turn on	Led bars leading with the housing	Changing the LED bars and changing r816 from 3r to 3r9 to drop the current on the LEDs, thus increasing their useful life	TECVIDEO
LG	42PG20R	TV works for a few minutes and disappears audio and then comes back.	After replacing several capacitors that were getting very hot on the main board and removing the cold solders from the power supply board, I identified that the audio output was getting absurdly hot.	I did everything I could to replace components around the audio output and nothing was resolved. The solution was to place a notebook fan next to the main board. The TV has been working for 72 hours and tsound has been no defect.
LG	20CD2R MC-059A	Closed vertical, with a thin green stripe on the right side	R 313 of 47k open		GDP2
LG	42PQ30R	Dull with audio	2r2 3w resistor position r503 on the side of the yellow transformer on the ysus board! This one is also cold soldered and causes the same defect, or the intermittent glow disappears!		GEMASI
LG	22LG30R	After changing the power supply board, the TV turns on normally when turned off, it no longer turns on	Replace cap1026 100/16 c309	After the replace run hug	Paulinho
LG	14FK3RB MC059D	Vertical closed	Damaged ic 301 and c309	With the replacement of the !c 301 the vertical did not open completely, the voltage coming from the t402 was low, after replacing the c309 the problem was resolved.	Ricardo Porto
LG	CM8360	Does not turn on or turns on with some functions locked	Key line 2 with 2.9v instead of 3.3v	Search for leaky keys, if you don't find them, it could be a trail with the ground (chassis)	Lucas
LG	42CS460C 6870C-0310C	TV turns on, has sound, backlight comes on, gives controls but tsound is no image on the LCD panel.	Short in c305.		electronicssupplyparts - Gramado/RS
LG	21FU1RL	Turns on for around 15mt and turns off	R420 240k	Replace the 240k resistor r420	Gilberto Costa
LG	32LN546B 32LN546B	Everything works, but tsound is no plot (white image)	12v dc power supply (ic404) with voltage below normal	Replacing ic404 (t8289) requires a hot air station, ci has central soldering, does not come off with an iron. Then it's just joy	RUBERVAL SBC
LG	55UJ6545	Image freezing, sound normal	Lgsbwac72 wi-fi card	TV freezes image and suddenly the image speeds up and follows the sound, in my case just changing the Wi-Fi card solved the problem.	megasystemav
LG	32LS3400 32LS3400	Turns on with backlight, but tsound is no image.	Loose screws on the main board, poor contact in the flat that connects to the tcom.	Cleaning the connector flat and retightening the screws.	MRS
LG	LM-U1060A LMU1060A	Low or no sound.	I changed the strx6759 and also the PC 901 coupler and it didn't solve the problem. I added a 470k resistor from pin 3 to pin 4 of the pc 901. and a 100k resistor from the base to the collector of the q 904 3 returned to normal operation, 35 volts that feed the audio output returned to normal. hug guys	Working now and move on to the next cucumber.	altair pereira pereira
LG	CP-14J50 MC83A	Turns on but not the image	Capacitor da power supply c816 220uf 400v	Replace c816 220μF 400v c814 160v 100μF c829 160v 100μF	Eudes Viana
LG	CM4450	On the radio it rings and cuts out immediately and the amplifier power supply goes up to 55v and drops. cutting out the sound	Open 20v zener diode 932	Just replace it and that's it. God bless you all.	Clebson Vale
LG	14SB1RB	Tv turns on stadbay and goes off without any voltage on the secondary, tv inoperative	It was the photocoupler, it killed the 5 volts	Replace even after measuring well	Eletrônica Melo-Boa Viagem -Ceará
LG	32LD460	8 volt voltage low on c659	Altered 510k smd resistor r609 measuring 391k was replaced after a major analysis on the main board the voltage on the c659 started with 6 volts and dropped to 4.71 volts causing image failures.		marco.32
LG	RP20CB20A SC-023A	When plugged in, the LED turns on and off, secondary power supplys arrive and drop to 0v	C826 - 470uf/16v, c408 - 2,2uf/160v	I replaced the capacitors, solved it	CTEletronica -Caruaru -PE
