Out of curiosity, is it a bootleg DVD or is it made from a copy protected video tape? Try a different DVD to be sure.
I just installed a simple 9.2" boss flipdown monitor connected to my main headunit. I have the 12v and acc connected to my headunit and I have it grounded to the body of the car. I originally had the ground connected to my headunit also but I tried out couple different places to ground because I thought I was having a ground issue and just ended up on the frame of the car. The problem I am having is when I play a dvd.. the screen start to flicker and black lines start to appear and it will come and go, it will be watchable for a few and then just distort, but when nothing is playing the screen is just fine.
Do you know if I can use a ground loop isolator that are used for humming audio to clear up video signal? or any other help will be appreciated.
I really wish it was that easy.. it's a chicken little DVD for my son. Original copy. Not bootlegg but I guess I will try another DVD in the morning just to be sure.
