and checking that the channels change. If the software is OK you most likely
have a problem with the firmware/PANCPU or with the power supply to the
lower module. Open the console and check the power LED on the PANCPU
to check the status of the power. Otherwise refer to section 17 to try and
debug a PANCPU/firmware issue.
Q. My console appears to have power but does not appear to boot.
A. There are a number of possible causes. There may be a problem with the
HDD not being detected by the motherboard (see section 21), a problem /
corruption with the Windows disk image (see section 22) or a PSU failure (see
section 19). It could also be a problem with the display. If you wait a minute
or 2 and you see the LEDs on the fader section of the console behave as you
would expect (mutes can be toggles On/Off, etc) then the console is booting
OK and the problem is most likely only with the display. Section 23 details
the various stages of start-up which may also be useful.
Q. There is a funny fan noise coming from my console.
A. The console contains a high quality, super quiet fan on the internal CPU.
Under normal conditions you should not be able to hear the fan. If you hear
fan noise the fan may have been damaged or something may be fouling the
fan blades such as an internal cable or other component.
