Power-on problems
If the system does not boot after you have applied power, check the
following factors that might have caused the boot failure.
• The external power cable may be loosely connected.
Check the power cable connection from the power source to the
power cable socket on the rear panel. Make sure that the cable is
properly connected to the power source and to the power cable
socket.
• No power comes from the grounded power outlet.
Have an electrician check your power outlet.
• Loose or improperly connected internal power cables.
Check the internal cable connections. If you are not confident to
perform this step, ask a qualified technician to assist you.
Warning! Make sure all power cords are disconnected from the
electrical outlet before performing this task.
Note: If you have gone through the preceding actions and the
system still fails to boot, ask your dealer or a qualified technician
for assistance.
