Make	Model	Symptom	Problem	Solution	By
LG	OK55	It works for about 15 minutes and disappears the sound	C.I. defective output amplifier	Made replace perfectly.	Eletrônica JJ
LG	32LN5400	Red LED flashes, goes out but TV doesn't turn on.	Q402, chaveia pwr on	To replace. Q402 (7BW), Side Side of the power supply Connector	joaomvjr
LG	CM4460	5.6Va Secondary was zero vic18v primary was floating	LC941 replaced
LG	32LS3400	League appears the logo and turns off, staying in loop	Capacitor Stuffed C201 10V 1500YF at power supply	Replaces with a 10V 2200YF and problem solved	Speed
LG	42PG20R	Do not turn on	C12 Capacitor and/OUC11 shortly on plate Z	replace shorted capacitor	Eletronicaaeb
LG	37LC4R	No HDMI picture or no sound, or with picture and sound cutting	C824 47UF/16V on the top top board near I.C of the HDMI.	replace C824, Tip of Friend Piu Piu on Youtube Area: external link ...	MIGUELTV
LG	32LN540B	Don't turn on.	Resold or d203 diode		Diego Abade. B.F Eletrônicos
LG	42LK450	It takes time to tune in and when it tunes later it runs out of sign	Do not tune	Com 1.2 v no c3705 replace seletronic	Fabio-ia
LG	CL-65	Turn on and off with Dprotect	Had no feed on sound output	It was the short -on -the -short photo of the gun
LG	47LD460	Does not turn on, without secondary voltage	1 mega resistor open	replace the resistor of 1 mega position R519, in the primary of the power supply	Gaeletronica
LG	42PN4600	Only one addendum to the previous tip: it was breaking my head. To kill if the buffer was really bad, I removed the plate from the place. The Y-SUS Osciled without the buffer and released the signal to the controller.	Good luck.		World TV - Sorocaba
LG	42PN4600	After recovery in Y and Z plates, yet the 18V did not oscillate, tension died.	YDRVTP (buffer) plate with one of the chips AN16538a burned.	Chip or drive replace.	World TV - Sorocaba
LG	47LD460	Erases standy bye doesn't start	Capacitor shortly killing 3.3V	Remove or replace the C619	Gaeletronica
LG	42PC7R	LG Plasma 42PC7R TV connects the reme and disarm. No tension vs and va. Rectifying !!!	Damaged power supply. She turns on, Arms the reme and disarms, flashing the green LED, so the LED comes back to red and remains turned off. When it is turned on, we have the 5V voltage on the power supply plate, but when the power is tight, the VA and VS tensions are falling, it is not even zero, but when it arms the reme, the 190V VS voltage appears quickly and falls to zero, that happens with VS, also happens with 12V, 19V, 3.4V, I already tested the power supply, I already tested the power supply Connected in energy, without any connected exit, and so does my theory that as I are not being generated the others are protected. I checked the VA line and found nothing short, the reference sectors I lifted all resistors and scraped the glue, because in some cases, with time the glue drives and throws in protection, but the defect persisted after removing glue under the components. The CI Q801 is not short, but is replaced in conduct, at first it is responsible for the 190V vs tension.	PFC TBM I replaced C603 (450V 270UF), R632, R633, R634 of 250k each. replace of Q801 (KTC3198) for a BC547 reordering the order of pins attention to this. I took the C802 (471 1KV) disk ceramic capacitor. SOLVED !!!	Adriel
