it has a 12v regular tv now and its jumpin with the car engine it works fine for DVD what I really think the problem is the alternator is shot so Im replacing that then ill see how the tv acts Im getting noise and the tv is jumpin with the engine idle I figured if I just go dvd it would be a direct line to the player thus cutting out the jumpin. but I do not want a tv anymore just DVD and for the amount of times it is used I do not want to go expensive.
I forget the particulars but what you need is a noise filter for the alternator, that should cut down on the "jump". You may not need a new alternator. If you have a TV in there now and can find a 15" 12V LCD "TV", I think you would be better off than trying a PC LCD in the car...
And I am sure that is what was causing the tv to go nuts its not jumpin no more the radio is not humming on am so I have to bet the alternator was throwing interference thanks for the help.
