Question about LG 47LC7DF 47 in. LCD HDTV
My 50 inch LG tv keeps shuting off and make a poping sound. i have to keep turning on maybe 5 to 7 times till it stays on but it takes like 5 to 10 min for the sound to come on what can i do
It sounds like you have a dying power supply module, that will be the first place to look, look for caps with leaking/bulging tops, some may look OK but can have high ESR (Equivalent Series Resistance), which you will need special cap meter to check that out.
