16700A: No display on external monitor

I have a 16700A with a screen and keyboard attached.  The bootrom winds up and does the initial tests, and displays the following on the serial port:

Firmware Version  1.0

Duplex Console IO Dependent Code (IODC) revision 1

Memory Test/Initialization Completed


But what it does not display prior to trying to do anything further is the message that reads:

To select a new Graphics Monitor Type press the [TAB] key now, otherwise EXIT by
entering any other key (or will time out in 15 seconds)..."


The video system is putting out synch signals that match the configured mode for the monitor, but nothing is visible on the monitor.   The system also appears unresponsive to the keyboard.
Both the keyboard and monitor are OK.

Does anyone have some thoughts on what might cause this particular set of behaviour?     Or how to find out what the problem is. 

I realise that unless I am lucky I will need to change a board, but at least knowing the likely problem area will help a lot.


PS It won't boot HP_UX in headless mode as the HDD is toast - I got a new disk drive today and am waiting for the Re-Ignite CD to be sent to me.

PPS Was there a CLIP for these analysers?
