How Bricked is this unit - SOLVED - bad memory

Hi

I own 5 readynas NV+'s purchased from new, we also have 2100's,NVX's at work. I've taken a risk and purchased a second user 2100. When power is applied the USB and disk 2 lights come on solid and the blue circle light flashes and that's it. If I've a network cable attached, then I get no lights either on the network switch or on the unit itself. Attempting to hold in the sys button during power on results in the same led scenario as previously described, is there any hope?

I've tried looking for a list of led error codes in the documentation, also on this forum and also by googling, the only led codes I can find are those associated with accessing the boot menu and holding in the sys button.

Is there a list of error codes available, is there any other way of gaining assistance, i'm in the UK.

Thanks
