Screen saver? :P
I have a 10.4 in overhead lcd that i put in my car with a headlight behind it. It works great when the car is off, but about 5 min after i start may car the screen will turn off!!! i can turn it back on but then it turns off again.
I think when i turn the car on the lcd get to much power and turns off.
How do i fix this problem?
Screen saver? :P
that is what i thought at first, but i turned the screen saver off and moved my mouse around changing mp3's and used my gps and it still turned off.
How are you powering it? Car power systems can be notoriously unregulated. You might want to build a voltage regulater to make sure the screen gets the proper coltage all the time.

Yea, what voltage is it? Is it a TFT lcd or a VGA?
I got the power from the body frame and the fuse box (heater)
* the transformer that came with it says 12v 1.5 amps but that will only keep the screen on for a min (like when the car is on)so i think it is to powerfull.
the only time it stays on is when the car is off.
also i took out the fans that came with the lcd so the whole thing would fit in my car.
this is the same kind as the one i have in my car only i took it out of the case, took out the fans and put a light behind it.
A few things to consider. Pulling from the interior fuse box? You're probably getting too much noise that way. Install one of the power line noise suppressors from somewhere like Radio Shack. Or, draw power from your PC's psu off one of the 12V and ground lines..the LCD should be able to handle a .5V difference. Also, that screen may get too hot and overheat...some type of thermal protection...without the fans and depending how/where you mounted it.

How did you mount the LCD overhead? 10.4" right? Can you view it directly from the drivers seat, or is it facing the back? I need some ideas
The lcd is right where the glove box was in a 1994 buick regal it fit perfect after i took out the glove box door the bord for the lcd fits in the box + a head light to light up the lcd.
I'm going to try to put in a resister so the screen stops turing off.
the problem is that u supplying to much voltage in to it. when the car is off the voltage is around 12v and its fine for it to work when u start the car voltage goes above 12v and it makes it to go off you lucky you didnt burn it or something.
Build a flyback regulator using National PartsLM2587 ( it think it was) or run it through your +12 rail from your PC!
