LG 37LC7D HDTV just went blank. Screen blacked out and green light is on but no response to input change, remote, volume, or channel change. I've unplugged it for several minutes in an effort to reboot it and let it have a time out and when I plug it back in the green light blinks for about 30 seconds but screen is blank and still no response. Did it die?

Have the power supply checked out. I've worked on your particular model with the same problem. Turned out to be bad capacitors in the power supply.

Try changing your input choices until you get a picture. This usually means that the tv is on and functioning properly but the input method you have chosen is not the right one. what I mean by input choices are aux, cable, input one or two ect. check to see where the antenna is connected to your tv by which input method you are using on the back of the tv. Then change that input method to match by clicking the button on the remote that changes it.

It sounds like a problem in the high voltage circuit. Had a similar TV set which had the same problem. When there's power leaking from the high voltage circuit, these TV's will tend to cycle on and off. Voltage leaks are mostly caused by accumulated dust for the most part.

check the power supply section.. probably the electronic component got problem.

i think by accident you have changed the input when you went to change the volume. look for a button labeled " input" or "video" select on the remote and scroll through the various choices. you should get your picture back.

Hi, I would buy your TV

HI,

I'll think your power supply is down.
Maybe there's still garanty on your TV.

kind regards,
