LG	42PQ30R	Does not turn on, power supply with noise	D352 on the short power supply plate	diode replace D352	ANTENA VIDEO
LG	55LA8600	With standby, backing without backlight, without sound and without picture	BGA Failure, Fountain Flashes 5x	Reballing, working 5 months ...
LG	42LC3R	Bind	Measuring outputs at P201 found 2V at the 6V power supply. Not found integrated from the sector for sale, made adaptation using 7806 regulator with 12V entry of the power supply generating the 6V on the output to the main. Adapted dissipping on the chassis and resolved.	Remembering to interrupt original feeding and use only the one generated by the regulator *sir poo your angels sound
LG	22MA33N-PS	Connect, see picture, no backlight	Connector that leaves V-Con to the bars with poor contact	Clean and fit	MAX L
LG	32LN546	Connect, without picture	Defect in the backlight industry. Resoldar t690u and capacitors that are in the same line, in my case resolved		AXCELL ASSIST TEC
LG	CJ44 EAX67136102	Apparatus arrived by turning off and giving protection	It is not generating the PVDD (high amplifier voltage)	replace the photo coupling location on the PC 903 power supply plate, is next to the larger power supply stuck.	BOSCA
LG	32LM625PBSB	With sound without picture	Coil l801 ao do us		Arimateia
LG	42PJ350	Do not turn on, relay arming and disarming right after calling.	Cold weld in the main power supply.	Resonold in the pins of all transformers, mosfets and power resistors. To avoid future failure points, also resolve components in which they appear to have little welding.	Moises
LG	50PB560B	pictureless	Defective Controlling Plate	Replace Controlling Plate	Eletronica NDN
LG	50PB560B	pictureless	YSUS in short	replace Q552, Q554 both SMK0460, R561 - 10 Ohms, C672 - 102K 1KV, C671 - 471K 1KV, D556 ES1G, IC 551 - P155E, D552 - CDZ55C56, comes only 56 in the zener 56V 500MA encapsulation	Eletronica NDN
LG	42LG30R	Greenish and sometimes flashing picture	Dirt on the lvds cable	LVDS Cable Cleaning (which goes from the main to TCON)	Wsmartcell
LG	49UB8500 lj41v	No audio, no picture, no backlight	Cold weld in IC100	with a lot of flow make the IC100 reflow and add thermal paste and a thermal rubber to improve callus dissipation	Marcos Paulo Infotron-ltda
LG	22MA33	don't turn on	Measure IC808 has to be 2.5V, if you don't have to measure Q 804 you have to release 3v3, in my case it was him, I made the jumper and the TV called, I replaced it		Mirage Eletrônica
TV LG	49UJ6300	decrease current in LED bars	reduce current in LED bars after the replace	replace the R801 to 2.2R 1/2W	Digitronica
LG	CJ87 Eax68563602	Inoperative power supply, without +5v	ZD905 in short	Place 13v Zener diode	Ivan Silva
