Remote should now work with tv.
To control volume and power at the same time... Press and hold STB and OK at the same time, let go, red blinking up top enter the code 977 STB should blink red a few times.
Hit STB, see if TV volume adjusts Hit POWER. see if both STB (Set Top Box) turns off and TV turns off.
All should be good.
If both TV and STB do not turn on/off, repeat the process for the code where you enter 977

It looks like an electrolytic cap. on the power supply. you may find that the guilty one is bulging on the top.

You can't fix it. There is a bad board in this set; either the main board or the power supply board. You'll have to call a professional.

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

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.

I DO HAVE THE SAME PROBLEM , ONLY THE RED LIGHT BLINKING ,NO SOUND NO PICTURE '
PLEASE I DO NEED HELP TO FIX IT .THNKS
