OK quick update, I pulled out the MPU board and checked it over quickly. It has had some ghetto repairs around U9.
I reseated the chips, now I het the quick flash and then two solid pulses.
Disconnecting the connectors (execpt for J4) gives the same result.
I read throught the manual, but the only pluses it talks about are the 7 on a sucessful startup.
