Hi,
Working on a Spy Hunter MCR stack. Received the A7 A8 errors and after confirming the ROMs and RAM were OK, replaced those 3 IC sockets, capped all three PCB's and replaced the ribbon cables, was starting to go over my work and my 8 yr old son comes down to help..........
Long story short, I did not in fact get to check my work and after powering up the rack and getting no voltage reading on the DMM, pulled it only to find that on one of the ribbon cables, I was off by one!
Well, I correctly installed that cable and now just get a bunch of blocks on the display so I fried something. I tried the test switch but that did nothing to change the display
I checked all three boards and cannot see any physical damage so there must be some IC damage, AFAIK.
Can anyone shed some light on this issue which I created for myself??
Thanks in advance
Jeff
