Chapter 14—Troubleshooting

• Main board troubles
- Check the fuse. If blown, replace with a 5A fuse. If the fuse blows
again when the power is switched on, the power supply is probably
damaged and must be replaced, see Chapter 11.1.
• Cable between main board and console board not connected or dam-
aged.
- Check that the cable is properly connected to CN22 on the main
board and CN1 on the console board and that there is no visible
damage. Replace if necessary.
• Faulty console unit.
- Try connecting the cable to a replacement console board without
actually installing it (mind the risk of electrostatic discharges). If
the trouble seems to be the console board, replace the entire panel
module.
