Try another cable as well. In fact, yours is an rca connector isn't it (3 plugs at each end)? While it's on, unplug the yellow one.does the screen change at all?
You could also try swapping the yellow connection for one of the other two plugs, so long as the colours match at each end (switch the tv off first if you try that).
Pete you don't need another cable to test what Jon suggested. If you're using RCA cables you have 3 plugs, 2 are for sound (left/right) and one (usually yellow plug) is for video. Jon wants you to make sure the video cable is good so he's suggesting to swap 2 plugs at each end.Say your plugs are red, white and yellow. Swap the red and the yellow plug at each end. If you get your image back but loose sound on one side then you'll know it's your cable and not your dvd player.
After plugging it back in there was no change. Still no video what so ever.I tried unplugging and plugging back in the yellow wire. Didn't help.So as a last ditch effort I searched for another wire. And surprisingly I found one. So I switched the yellow wire... and It Worked! I just don't get it though! How could that wire go bad that fast. Worked perfectly with a beautiful picture one minute... no sooner I wrote my review... and popped in the next movie (matter of a few minutes)... it stopped working? That just don't make sense to me!
