best to post in the merit/JVL touchscreen sub for maximum exposure...
http://forum.arcadecontrols.com/index.php/board,54.0.htmlthe battery on the board has likely died. the motherboard BIOS is normally set to come on after the power is lost, but by default it stays off. pull the board and change the button cell battery on the actual motherboard (CR2032)
connect a keyboard and then you can then jumpstart the board by jumping the 2 power switch connectors on the board. On the force boards the header is located in the very corner of the board. if you where to hold the board with the board components facing you and the monitor/keyboard/usb connectors to the top it would be on the bottom left side. it will have a black connector overtop of all the pins with 1 or 2/3 black/white wires (depends on version) on it. just pull the block connector off and jump the power switch pins. I don't recall exactly which 2 pins...it's at the end of the block of pins.
once you have the board going press delete to enter the bios and change the "On AC power loss" to "on"
if the board refuses to power up, may have a bigger issue.
