When I turn the system on, it sounds normal, lights flash on the
keyboard, but the monitor remains black. Stop-A does nothing. I even
attached a PC monitor to the D-sub port, but no joy there either. It
seemed like there was some signalling coming from the CPU to the PC
monitor, but after a couple of flickers, it remained black. As I
mentioned, I have a MicorSPARC that I did system maintenance on for a
few years, so I'm pretty familiar with Sun/Solaris. I'm really
stumped about this. Is the CPU I bought on eBay D.O.A.? Any help
would be appreciated.

Did you try connecting a terminal to the console port (serial port
A)? It could have all output forced to the serial console in OBP.
Setting the OBP to defaults would fix that.

Yes, I thought that's what it might be, having read some of the other
threads. I'll give that a try. Thanks.

One other possibility could be that the resolution is set to one
which the monitor will not support. I've had the same problem with A
couple of machines which I have just retired (and thus the
"output-device=" setting was for a resolution which kept our LCD screens
happy, but not the 17" Sun monitor. I got just the same results which
you did -- with the final status being that both the green and amber
LEDs were on on the monitor.

So -- give it the magic keypress which will force the OBP
settings to the defaults (in particular, "Output-Device=screen" without
a resolution on it. The magic keypress is "STOP-N", in case you didn't
know.

If it *does* turn out to be the system board -- you can probably
pick up an Ultra-5 for less money -- and they are the same, just in a
different package -- so you can swap the board to your current box to
take advantage of all the extra room in the Ultra-10 box.

Good Luck,
DoN.
