Yes, the filtering electrolytic capacitors are aged and require a longer than normal time to charge and at a higher amperage. Replace them ASAP, before they fail for good and fry something else in the process.

Red/green light keeps blinking.


This issue is related to a bad/failed power supply inside your TV.

Call LG to see if your TV is still in warranty. 800-243-0000

If not in warranty, the power supply is about $225.

Good luck. I do hope that I have helped you.

Powers on for only a few seconds


if the power light blinks and the status light is off, check the lamp door. if the power light blinks and the status light is steady red or blinking green, you have a power supply/ballast issue. you may have to send it in for repair. try www.avsolutionsny.com.
