Help ..Help.. Brother needs some help !!! with DVD screens

[Pitbull]

Hello ..
As I sit conteplating cutting a major artery, because I recently installed 2 xovision 2708 7inch sceens in the head rests. Bought a navigation bezel for another screen same model and size.
Everything was lovely until the 3rd screen was installed.I would get these vertical half inch lines every 10 minutes on all screens .I am using a video booster to beef up the signal.I was going to get this device to switch from playstation to or dvd to each monitor .But I got to get the screens right .The installer re -ran the ground ,mainline power in from the battery .One screen by itself look like HDTV,but when it is time share the signal,it is annoying to have a good pic distorted.Me and the installer are about to cut our wrists.Please help .
thanks in advance.David

Did you remove the speaker that is behing the screen? The magnet from the speaker will interfere with the monitor and eventually fry it.

I don't think that is his problem. Read Carefully...

if all of the screens are hooked via video cable through the same source then the interence will travel through the cable

Remove links in the chain until you find what causes the problem. EX: unhook the third screen. If not there anymore, replace screen. If still there , replace cable, etc. Eventually, you will find the weak link.

Could be the video booster (amp). Might be some sort of a refresh issue.

FYI, LCD screens are not effected by magnets (no electron beam to distort). That is only an issue for CRT screens. Just like LCD screens do not need screen savers, no phosphorous to burn in.

Good luck.
