Power-on problems
If the system fails to boot after you have applied power, check the
following factors that might have caused the boot failure.
• The external power cord may be loosely connected.
Check the power cord connection from the power outlet to the
power cord socket on the rear panel. Make sure that the cord is
properly connected to the power outlet and to the power cord
socket.
• No power comes from the grounded power outlet.
Have an electrician check your power outlet.
• Loosely 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.
