System not booting up (or partially booting)
1. If the Touch Panel has no video, re-seat the USB cable on the J100 of the
BEP. If there is still no video after 1 minute, power down the system. Open the
upper OP Panel and re-seat all cables on the back of the Touch Panel, and re-
seat all cables on the bulkhead board (small circuit board behind Touch Panel).
Inspect all cables for pinching and/or damage. Replace anything damaged.
Rule out the Touch Panel video port, J100 (See BEP Door Label.), as a
problem by plugging in a mouse. If the mouse works, then troubleshoot the
upper OP Panel and cables.
If the Touch Panel video does not display, replace the Touch Panel and the
main cable harness. Reload any drivers.
2. If the LCD monitor has no video and the fans are running high, attempt to
reset the BIOS as described in Section
Memory" on page
Step 3.
3. If the LCD moni t or has no video, power down the system. Re-seat the Video
Card and flex cable in the BEP, on the motherboard and the I/O Board. If the
system has a DVR Card, disconnect the flex cable from the DVR and connect
it to the Video Card. If video returns, replace the DVR Card.
If video is still not present, re-seat the video cable connector underneath the
upper OP Panel and inspect the cable for any damage.
If video is still not present after trying the above procedure, then plug a monitor
into the rear DVI port on the BEP. Use a DVI or VGA monitor with an adapter.
If video is present on the separate monitor, replace the flex cable. If video does
not return, order a new flex cable, I/O Board, and BEP. Try the flex cable and
I/O Board first to determine if they are the cause. Resort to replacing the BEP
last.
1. The known causes of this noise is a blown fuse in the BEP EPS or the EPS
battery cable is not fully seated in the connector.
Check the fuse in the EPS on the BEP. Replace the fuse if it is blown. If the fuse
is not blown, re-seat the battery cable on the EPS circuit board. If the noise
does not go away, order a new battery pack assembly with cable.
2. Replace the I/O Board.
