Hi I got this tv and when I plug it in a green light comes on when I hit power.

I see a light flash the screen has light in background and its still no picture. This flashes for 1 second. Everytiem I hit the source button it does the same thing. The light wil lgoto to orange . And at times back to red and it will power off on its own . Theni have hit power again.

Also if I hit the the channel down it acts just like the source button .And the tv will shut off if I do it 3-4 times.

I get no picture or sound . Any help be greatly appeicated.

I tried replacing the main board and still the same thing .
