    Xenarc issues

    I recently bought a damaged xenarc unit. The previous owner had broken off the flimsy little video input receptacle. No biggie. I soldered it back onto the board and used ABS hot glue on the edges to keep the thing planted. Everything worked fine. I put it back in the case, threw it in my car and drove around for a couple of hours.

    Today, I take the display out of the case to start molding it into my dash. I get the front bezel molded in and place the monitor into the housing. I plug power and video in and I don't even get the "Portable Display" splash screen anymore. The power LED stays on and none of the buttons tend to function.

    Help! I can't figure it out.

    Can anybody offer ANY help? Even links to places that carry parts for the GAIN boards, schematics to the GAIN boards, ANYTHING at all would be appreciated.

    Is the touchscreen board plugged in? Is the backlight inverter board shorting out on the main board? Is the little ribbon cable between the display and main board plugged in properly?

    Is the touch screen USB? Can you take a picture of the way your touch screen controller is connected to the controller board? The white connector on the touch controller has 5 pins but the little wire cable has 4. They need to be connected in a certain way. Other wise it will do what you're describing. Also another way to test the VGA board is to unplug everything from the controller (VGA) and connect it to 12V. The LED should come one and in a few seconds it will start blinking (stand by mode). If it does that then it should be OK.

    This could also be a more serious problem. I have new controllers but they are not cheap.

    I didn't change ANYTHING as far as connections go. The video input connector may have come loose.

    Armen, the screen does what you said. It'll go into sleep mode just like it's got video on the board. If I hit the source button, it'll stay solid and then go to sleep mode again. If I unplug the touchscreen controller from the main board, what will happen?

    I'll try to take pictures later.

    Armen, if I'm looking at the top of the touchscreen PCB with the black connector at the top, the plug is skipping the left connector in the white plug.

    From your post above it sounds like it is working. When you attach the LCD panel and the inverter it stops working?
