I have a pyle monitor plvs7hm. I hooked it up to my video source and all i get is a blue screen . I have tried hooking it up through the yellow video component cable and I can not get a signal to appear on the screen. I have two video outputs coming from my indash dvd player. I have tried hooking up from both ports and i still can not get it to work. I had a screen prior to this one and it worked with my indash dvd player. If you have any information I would appreciate anything I can get. Thanks
