LG	32LG30R	Works normally when turned off does not work the LED changes color	Replace the r128 resistor with a 12k one	This procedure was carried out until today the TV has not returned	This email address is being protected from spambots. You need JavaScript enabled to view it. BRUNONIKACIO@HOTMAIL
LG	21FE85G	It doesn't work and tsound was no voltage in the horizontal output collector. It was shorted. I removed the voltage and replaced it with another one, but when it turns on, the voltage drops to zero. and the stand by LED lights up when the LED turns off and comes on again	Open 1r2 resistor fr403 of 2 watts.	Replace the horizontal output and the open 1r2 fr403	eletroclaudio aguas belas pe
