I am a little baffled by my EK - the boards are original, repinned, and "bulletproofed". The cables connecting to the boards were repinned. , and NVRam installed. When I turn it on, everything goes through the normal sequence - 7 flashes, the displays show zeros, etc., then right after the chimes are done sounding, the displays go blank, and nothing works. All of the power test points on the MPU are rock solid, even during the chimes sounding. This started happening a few days ago - before that, everything was fine.
I'm not sure where to start - Any ideas?
