TROUBLESHOOTING
There are no user serviceable components inside the LC8700. Service should be performed
only by Bematech or qualified personnel certified by Bematech. The following guide lines will
help in identifying the source of a problem:
VGA monitor display is blank
1. If the power LED on the monitor is off, check that the monitor is properly connected to its
power supply and the power supply is properly plugged into a functioning AC outlet.
2. Adjust the contrast controls on the monitor display.
3. Check that the VGA cable is plugged in properly on both the monitor and the LC8700.
4. If the power LED on LC8700 is off, check that the LC8700 is properly connected to its
power supply adapter and the power adapter is properly plugged into a functioning AC
outlet.
5. If the LC8700 is connected to a power supply but the power LED is off, press the power
button to turn on the unit. If it does not turn on, try replacing the power supply.
6. Replace the LC8700 if necessary.
VGA monitor display is blue or frozen
1. Reset the LC8700 and check the system information on the screen during boot up.
2. If unit reboots correctly, try running application again. If same problem occurs, try
reinstalling the application software.
3. If unit cannot reboot correctly, try replacing the hard disk drive (or compact flash).
Station is not communicating with server Application
1. Check that the LC8700 s' IP addresses are correct and unique (no conflict) and the port
number matches application software setup.
2. Check the Ethernet cable connections at the problem LC8700 s and at the Ethernet hub or
switch.
3. Check that host server IP address matches the LC8700 IP address group. Try pinging one
of the LC8700 IP address from the host.
4. Check host server application software setup. Restart software if necessary and test
again.
5. Reboot the host server and test again.
6. Replace Ethernet hub or switch and test again.
LC8700 does not respond to keyboard commands
1. Check the keyboard cable connections at both the keyboard and the LC8700. Unplug the
cable and re-insert fully. Check whether it snaps in correctly. Note that its necessary
to hold the back end of the PS2 connector near the cable exit and push in hard to get
the locking connector into place.
2. Test with known good keyboard and cable. If it works, replace the cable and/or keyboard.
