The SG doesn't power up after switch on. Power supply is ok.
I looking for information about the diagnostic LED's on the CPU, pn: E8251-60006.
This could probably help. Thanks.

Thanks for pointing that out to me!
For anyone that's reading this post, the service manual can be downloaded from the link below, and you'll find the LED sequence table on page 24 (table 1-3).

Sorry for the delayed reply. I saw no-one had responded to your question yet, so I spoke to one of our support engineers to get his advice.
His recommendation is that the unit be returned for service. He can't provide the info you've requested on the diagnostic LEDs, but if he was to hazard a guess, then it could be a problem with the A3 power switch.
