LG LCD video turns black

I have a LG 47 inch LCD TV, 47lc7df, about 2 years old. All of sudden, my video began going out. The audio stays on, but the screen turns a dark blue/dark black. I have to unplug the TV and then it comes back on.
I have a home theatre system involved. I thought my receiver might be having problems, but unplugging the TV solves the problem. I do not have to do anything to the receiver.
So, I think the TV is the problem. It only happens about once a week.

I have changed the input HDMI port I am using, but it still happens.
I have not changed HDMI cables yet. Is it possible this is a problem?
I have contacted LG about a firmware update, but have not received anything yet.


Any ideas on the problem?

It could be the power supply that needs to be replaced as a guess. Do you have the TV & other connected devices plugged into a surge protector? If not you could try that in case power spikes are causing it.

Good luck!
