My friend recently gave me 2 Absolute HM65 headrest monitors and i tried testing them b4 installing them and i hooled up the red wire to my inline fuse holder that i have on the battery and the ground directly to the negative batter terminal, the unit turns on and it displays the picture but the back light of either two monitors wont turn on. Idk what it could be i was starting to think that maybe it wasnt getting enough power but i dont know... If anybody knows please help or point me into the right direction. thanks

sounds like you have a couple of problems. 1) your headrests accessory wire is not hooked up or it doesnt have one, that would fix your problem with the movies starting all over again. check this by changing your color really high or low on a monitor turn the key off wait a few seconds then on again then check to see if the color stayed the same, if it did then you may have low quality or off brand monitors. 2) the sound issue could be kind of tricky the rear headrests may be hooked up but you may need to turn the sound on trough the head unit and this all depends on the make and model you have. i would suggest you take this to your local stereo shop or wherever you had it originally intalled. they should be able to check this out for you.
Youll have to run sets of cables from your head unit to the seats, youll prob only need video, power, and ground if the sound will come from your speakers. For the same display on either monitor run to first position then link the 2 monitors.
It could be that the monitor was installed upside-down; other than that, check the settings on whatever device your feeding video to the screen with- a PC, a DVD player? It might have rotation settings.
