    Xenarc screen doesnt work.

    So my setup is finally finished. Went to turn on the screen and nothing. Took back inside the house nothing there either. Tested the system and it worked fined inside the house. Nothing comes on at all. Anyone have an idea whats going on? The instruction manual said the the wire with the lettering is the +battery and thats what I did. I cant send it back either because i custom molded it to the dash. Any ideas, help?

    Can you get at the circuitry of the LCD? If so, smell it. Does anything smell burnt? (like an OLD television) Sometimes you have to get your nose in real close to smell it. If it smells like ozone or burnt circuitry that's very bad. If it smells, chances are really good that it'll take a professional to fix it, if it can be fixed.

    If it doesn't smell check it over for fuses. You may have burnt one out. Those aren't too hard to replace.

    Then double, triple, quadruple check your wiring. Use a meter and check where you wired it up. How many volts are you getting there? Amps? Is it what you expected? Is the polarity what you expected?

    If all else fails, leave the screen sit unconnected to anything overnight. It may act normal in the morning.

    Past that, I dunno. Good luck!

    Nothing smells burnt. Ive installed systems in cars for years now so I know what im doing. I dont smell anything. I tried it in the house with the original power supply and nothing still. I worked on this so hard for months. And now...450 down the drain. I cant even return it because i custom molded it to the dashboard. I dont know, maybe ill sell it on ebay for parts. Its just so frustrating.

    are you telling us you molded the screen into your dash before you even tested it?
    Mine needs to be updated.

    Of course not. The screen worked fine when I got. Worked fine after I molded it to the dash. Today I put my pc in the trunk. The only step that was left was to connect the +B to the monitor. Did that, and nothing. Took the dash out of the car, brought it inside the house. Used to original power supply...and still nothing. I have no idea what could possibly be wrong. I dont see/smell anything burned. I followed the installation directions perfectly. Does the monitor have some internal fuses I dont know about? I dont know what to do anymore.

    As I recall, Xenarc's power cord with writing on it is neg. I triple checked my polarities with a multi meter before I did any wiring.

    If you still have the original power adapter, use a multi meter and check the polarity on it and voltage. Then power up the LCD accordingly. You probablly just fried the onboard PSU. Xenarc charge $60 to replace it.

    Yeah I checked it, sure enough i did switch the polarity. Like I said though, i went by their instructions. When they said to check the wiring with a multimeter, I thought they meant on the car. I got the screen from dscustoms. I wrote them an email, and well see what happens.

    One has to assume that if you've been doing installs as long as you claim then you would have used a fuse on the power line to the screen. Obviously you checked the fuse then? Fuses are used for good reasons. Good luck.
