My guess is that the regular flashing shows that it can't go on beyond the front panel hardware selftest routine after it gets turned on . . .
I have a lot of experience with blown up hardware and i'm 99% shure that one of the regulator circuits on the main board has shorted out and turned off some of the main hardware .
As you could see , the display unit gets power and is still working - the front panel and the power supply are working as well - that narrows it down - and i don't think Dave has done something to f*** up this scope
Of course i'd like to know what really went on inside .
FreeThinker pointed to it : Is Agilent going to share this information with us ?
