If you have no Blue LED, that means the server is not on. First things to check are that the power switch on the computer box inside the DL is on, and that the IEC power cable is connected to the computer (both of these will require opening up the unit, and taking the computer unit at least partially out). My guess is one or the other got overlooked when the unit was serviced.
Other things to look at are: - Can you acess the units' menu directly? - If you disconnect power and then re-apply does the issue persist?
