hey folks i have 2 20" tvs and 4 7" tvs in a 87 g body...now when my screens are on with car off they look crisp and clear not even a flicker of any kind and work perfect...now when i turn the key to ignition on or start the car my tvs go crazy all kinds of lines going up and down and intermittently the screens will result in no video(blue screen) or just black ... any ideas where to start? thanks all in advance

start by checking all your grounds as well as all other cabling connections.

the power is properly fused and distributed from a batt source from the main fuse panel and the grounds are all individually grounded to body with a DMM i checked resistance and it was good and voltage loss was practically non existing...

i'm assuming you have some kind of signal splitter to send signal to all your tv's try connecting 1 at a time to a source and see if the problems persists. Perhaps if you have only a splitter you need an amplifier. Also perhaps you have a bad signal cable somewhere.

free and clear guys as my dash is out i took the liberty of rewiring EVERYTHIN...needless to say i may have ruined one tv and my startin circuit is not engaging will try fixing that soon i hope anyways everythin else works .... the only two things that changed i wired + Pos straight to the batt properly fused each tv of course and grounded all of it straight to the batt as well....perfect so far as my key on power is working and before it would go crazy on jus ign power but i want to get the car actually started to see any change which i doubt now but stil keeping my fingers crossed lol will keep updated once i do get it running .... thanks all for your input
