Hi,
Having trouble with a second ICS64 build. The board keeps failing during the diagnostic sound test (586220 diagnostic cartridge). It stalls sounding one tone. All the chips work when placed in the the first build. The OLED display works fine and I can change to different OS systems loaded in the kernal chip. Sometimes after turning on the board, without a diagnostic cartridge, the screen hick-ups and freezes with a fast blinking prompt. The board passes the dead test.
I'm wondering if I could have cooked some SMD components the backside. Any suggestions?
Thanks
