My LG TV was fixed by baking the main board. Preset oven to 385 F, bake main board for 10 minutes, take it out to cool. It fixes one of the soldering joints.
My LG tv will turn on occasionally but other times is completely unresponsive to either remote (new batteries) or power button on the TV?? I’ve tried the power cycle reset but no change. Sometimes it works, sometimes it doesn’t - really frustrating!!
What if after the first steps (depleting the energy) then after plugging it again the tv flashes the logo screen on for a second then goes back to black?
It's the led light strips. Either you need to test with a led tester each strip and individual led if necessary. Then solder a the broken or dim ones, and/or just replace the entire strip without soldering.
@@HuhWhatHuhwhatHuh coming from someone named “HuhWhatHuhWhatHuh” I guess it makes sense that “unplug your TV and plug it back in” would seem like valuable information
