Attached are pics of my monitor. Yes, it's a Pyle, but I had trouble finding an in-dash 4:3 monitor. I can't stand the "squishiness" from a 16:9 monitor, especially when you're playing a video game. Anyway, I can't get the unit to power up. I've attached it to a 12V source (a spliced molex connector from my computer) and I've measured the voltage going to the wires to be 11.98V. I had this problem with the first unit, returned it thinking it was DOA, but then this second unit doesn't power up either, so I'm guessing I'm missing something. Any suggestions would be greatly appreciated. I've tried completing the parking brake circuit as well, but with no luck. Besides, shouldn't I at least get the LCD clock display to power up with or without the green parking brake wire?

Quit messing around with the computer's power supply. Just go out and hook it up to your car's battery to test it.

chop the molex and wire it as the unit says.. just ground the green pk brake wire, it should rifle up fine...

My computer's PS actually puts out a more consistent 12V than a car battery. It's just a convenient way to test the system without having to hack into my car or mess with my car battery terminals. I'm thinking I have another dud. I've already checked everything. I've checked the wires coming toward the near side of the monitor, and they're receiving 12V, so the unit's receiving power, it's just not deciding to do anything with it. May open up the unit to see if there's anything I can do, but I doubt it.

As log as that green is grounded it should go fine, Have you tried putting a video source into it?

auex may have a point, man. The 12V supply on a PC is far below the average current supply you may need for a motorized monitor. I use the 12V PS from a PC to test monitors, and it works fine, but only because the current draw is under .3 A.

You may have to hook it up on your car for a real test.

Does the monitor tell current draw?

Well, it wasn't a current issue. I connected the yellow wire to the red wire and it powered up. Weird. They should make it more clear in the wiring diagram.

I was looking at the diagram again... Back Up may mean backup power source, not backup camera. *smacks head*
