S4C+ M2000 will not boot up.

Hi all,
S4C+ M2000 will not boot up.

Teach pendant reads:
Wait!
Startup in progress.

and counts up indefinitely with out ever fully booting. 

I don’t have another teach pendant to try but it seems ok.

I’ve cycled the power several times. 

The robot has not been powered up in approx 2 years.

Here are my LED's

Can anyone please advise? 

Thank you.
