Hi,

I have a 42 inch LG LCD tv its about 7 years old.

When I turn it on it will work fine for a minute or two then it will go black but the sound still plays. after about five minutes it will either come back or i have to turn it off and turn it back on again and it will work fine.

The issue also only seems to affect the hdmi inputs.

Any ideas on what this could be and how I could fix it?

Thanks
