Unplug it for about an hour to let it reset itself, if it still does not work, then you will have to do more in-depth troubleshooting.
It is flashing because it may have bad power supply or it is in safety shutdown/restart mode due to shorted circuits some where. Inspect the caps in the power supply first.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Lg 42" tv not displaying screen image


The t-con board controls the picture. To test it shine a flash light on the screen abd see if you can see an image when the TV is on. If you do then the T-con board is OK. Look at the back light ballast board (sometimes is part of the power supply board) If you see no movement or a dim picture with the flash light, then the T-con board is gone.

Hello have a problem with tv Model is: lg


http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=6281

The above link goes to lg's website describing the red flashing light where the power switch is, and

another switch down below which can turn that light off.

Try switching that other switch below off so the light turns off. Then, switch it back on.

If that doesn't work, then service should be scheduled for this discontinued model.

Hope this helps on your lg tv.

My TV will not turn on....it's red light just blinks....stand-by mode? I have called LG and they had me unplug it and hold the on/off switch down for 30 seconds then plug it back in. Still does the same...


The main board or the power supply is seeing a start-up problem.
When there is a start-up problem discovered the TV will flash the red light and the TV will not be allowed to power up.
A TV service tech will have to check out all the different boards to find what the problem is. Sorry, there is not an easy fix for you issue.
I hope this information has helped you.
Good Luck.

Trouble switching on from stand-by from remote?


You should have a 1 year warranty if purchased new. Probably the main board.
