When I power up my LG LCD TV the power light continuously switches from green to red and the TV does not start up?

Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

may be power supply need more information

Use the remote to switch problem,if it's not works,I am sure the power board problem

My LG 17LX1R had a almost the same problem. Red standby went to green for 1-2 seconds then back to red standy. Turned out to be bad caps on the power supply board. Yours is definately going to need to be opened up. Not a generic fix. You gotta ask yourself if its worth fiixing a 6-7 year old LCD tv with limited LCD life. New ones can be had for about $130-150.

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.

call lg

bad main pcb

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

Hi Johnpb54,

May i know, what's your lcd tv brand and model? When the light change to red color, is it a steady light or blinking light? Or you need more info on repair lcd tv, please visit this site http://lcd-television-repair.com .It may be can help you solve the tv problem.

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.
