LG	CJ98	No sound, everything else ok	X600 spacious		Adão Rosa
LG	14CB25A MC-059A	Vertical closed (I solved it, and the TV stopped after a few minutes), it wouldn't turn on with the stand by LED blinking (I solved it due to a leaky zener diode), low sound/audio (I solved it by changing capacitors). presented three defects in this sequence	Closed vertical: r301 of 15k (was changed to 22k, close to vertical); did not turn on: zd851 (6.2v) connected to the photo coupler pin.; low sound: c504 (near the varicap) and c602 (near the audio aid).	This one took work, but we did it. check and replace the aforementioned components; good luck.	Eletroboy
LG	42LG64FR	White screen, functions don't work	Rewriting of ic 802 atmel 24c64a memory, they sell the data on the internet.		Marcelo
LG	22MA22D 26MA33D 28LN500B EAX65374603 (1.3)	Monitor does not turn on	Chip responsible for the 1.2v line ic803 (mp2315) visibly burned	Replace the IC, which is an mp2315, or place a linear converter or some other 1.2v voltage regulator on pin 3, which goes to the 1.2v coil. To test if this is the only problem, simply remove the burnt IC and inject 1.2v into the L801 coil, this coil goes directly to the processor, so be careful not to get the voltage wrong. a simple 1.2v 1117 sot-223 regulator will not work as the current is quite high.	Darci Denzer
LG	47LG60FR	Turns on the image and turns off after 4 seconds	The defect was a leak in capacitor c842 next to x1000	Just remove the c842	David Jacobina
LG	CM9750	It turned on normally for a few seconds and turned off "off auto power -e good-bye"	Panel tactile key	Replace all the tactile keys on the panel..... problem solved	neupsx4

LG	26LS3500	Lights up, has backlight but no image	Ic 3310 has 3.3v at the input and no voltage at the output	Replace IC 3310 (2.5v regulator)	jose almeida tavares
LG	47LG60FR	Backlight off, flashing when starting, but does not light up.	Oz9966sn oscillator on power supply board, responsible for switching the backlight circuit.		Eletrônica Maurício

LG	22MA33N	Does not turn on - short in the 19v input from the external power supply	C1112, but it could be c1113, c716, c718, c803 or c804		Fernando S
LG	50PA4500	League with blurred image on screen	Check r408 and 410 2r2 on ic402.	Replace them because they were open, good luck.	Eeonal Eronaldo (ERONTEC)
LG	50PN4500	Does not turn on victim of electrical discharge	10v zd303 shorted and ic 301 strw6054s shorted 4a fuse open pfc fuse	Replace them	orlando lott
LG	40PFG6309	Nothing turns on, victim of electrical discharge	Dz303 10v zener in raw and ci strw6054 in short pfc fuse open	Just make the replaces	orlando lott
LG	50PN4500	Ysus curto	Q554 q552 if q404 q403 are shorted you have to change without measuring ic403 ic404 d441, if q401 q402 is shorted you have to change ic401 ic402 r408 r410 c405 c407 (10r), resistor r106 2k2 next flat connector that comes from the control board.
