Sorry, but once again to confirm:
The D8B console lights up normally for maybe 20-30 seconds and the faders respond, before all the lights turn off and only the Rude Solo light stays on?
If so, it's getting more and more likely that it's a power supply issue, as suggested by RJH_MUSIC.
Before that, though - to still eliminate possible other causes, I'd try this next:
Shut the D8B down, and remove all I/O cards and all DSP cards. Re-seat the clock card and the even the Digital I/O card (with the S/PDIF I/O on it).
Try to power the D8B on again after that (with only the clock card and the S/PDIF+AES card installed).
Does it still lock up after a few seconds after bootup?
Depending on how you routed audio into the console before, you won't have audio in this configuration... but it would be good to know if the faders on the console still control the faders in the GUI after the time it usually takes for the console to freeze up.
If it still freezes up like that, I'd try to re-seat the Com1 and Com2 cables inside of the rack unit (the cables that connect to the "Console Data" connector on the outside of the rack). If it's STILL a problem after that, then I'd unplug the power put the power switch to the ON position (to help dissipate power from components), wait for at least 15 minutes (to let all the power drain), and then carefully look inside the power supply side of the rack unit, if any cables came loose etc.
If not, and everything looks like it should, then I think it's time to go with RJM_MUSIC's advise for replacing hardware components that may have gone bad.
I personally don't have much experience with power supply hardware, so I won't be much help with that, sorry! (In fact, I'm asking a power supply related question in another thread right now, myself).
