    Monitor not powering up. Help!

    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. It's a stop-gap measure until Xenarc comes out with their touch screen in-dash. 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?

    well obviously just ground the green wire rather then hooking it up to the parking break (for TESTING purposes). Also, check the fuse on the red wire.

    I believe its used to automatically switch the screen to a rear view camera when you shift into reverse.

    Anybody have any idea what that little rod thing is in the diagram (between the red 12V and the batt)?

    Checked both. Resistance between fuse was less than 0.5 Ohms.

    Ok, a little car stereo info...

    Red is switched power...key on ignition. (I think that is a KEY symbol)
    Yellow is constant 12v. Must have a clock or something to keep powered up.
    Black is ground.
    Green goes to ground to let the unit turn on when the brake is applied.


    To test, connect the black and green to 12v NEGATIVE
    and connect red and yellow to 12v POSITIVE

    i'm having the same problem with my monitor which is a tview t-700ts but mine only has two connectors for power. one black, and one red... i can't get it to power up at all and initially it did power up for me once before but i've tried again and again since then and nothing. what could be the problem? the way i connected it the first time was using the power supply from my pc which i tapped the red and black wires on and it powered up. what could you guys tell me about this? i'm about to give up on it and order a lilliput but i'm down to my last dollar with this project and i'm losing faith fast!
