The fault sounds like a PCB failure which would require an engineer visit, as the clicks your hearing are relays, probably the same one but trying to 3 times and failing.
If there are no messages displayed on the LCD when you turn the unit on, my suggestion is you follow the troubleshooting guide outlined on page 101 of the manual found here, this should ensure all the user configurable settings are correct and avoid you getting an engineer out for something you could have fixed yourself.
The only other thing you could check, is to see if any fuses have blown inside. Disconnect the power open up the case by removing the screws on the side and see if the 2 fuses inside have blown by testing them on a multi meter.
