If you are experiencing problems with your LG TV, such as it not turning on, your power cord might be bad. The good news is replacing the power cord is simple -- modern LG flat-panel TVs have removable power cords, so replacing the cord is as easy as buying a new one. Troubleshoot the issue first to make sure the cord is bad before spending the money, although new cords start at only $8 as of the date of publication.

No Power

If your LG TV won't turn on at all, it's possible your power cable is bad. Look for obvious signs of damage, such as if a dog chewed through the cord or if it's tightly kinked behind the TV. Also, unplug the cord from the wall and the TV, then plug it back in. If the TV still won't turn on, your cord may be bad.

Sound Problems

Check your power cord if the audio on your TV is stuttering or goes in and out with a buzzing sound. This could indicate an electrical problem, including one with your power cord.

Picture Problems

When your power cord goes bad, the image on your screen suffers. The colors may be all wrong -- such as green and red instead of normal flesh tones -- or there may be waves or lines in the picture. It may also fade in and out as the power from the bad cord fluctuates.


Remove your bad cord by unplugging it from the wall first, then from your TV. Order a replacement cable online from an electronics supplier, or visit an electronics retailer. Compare the new cable to the old one to make sure the connections are the same. Plug the new cable into your TV, then into the wall outlet.
