I don't know which OS you have but there is a power management setting and most likely in their it is set to switch the monitor to sleep mode

There is no power supply. There is a power cable and a data cable.

Possible that the processor sectionhas encountered a fault and since the processor is not working the customer panel controls are not active. Unless the panel is removed and the main board is taken out the processor cannot be checked. Sometimes it can be due to moisture build up, if so use a heater to warm up. Also check the +5 to the processor before we can go further.

What happens after the welcome screen?

the ribbon-cables that connect the panel to the control board were damaged.. try taking it apart and disconnecting the panel and re connectinng it..

hope this helps

That button can be set using the utility on your programs list

It maybe that you accidentally turned it off or set it to do some other task.

Start there first before re-installing the program that sets it.
That is on one of the cds that should have come with it and can be installed by itself.

I would try starting up and go straight into the BIOS. Set up your system and reboot.
