I brought home a Defender from Paul (pcolson) and started working on it today. It powered up, made the startup chime, then nothing. First, I replaced a fuse for the -5v. No change. Then, I reflowed all the header pins on the ROM and CPU board as well as reseated all the ROMs. But now, when I turn it on, I get a low buzz (not a chime) and all 4 LEDs on the ROM board are lit. Then, silence.
Did I just kill it somehow?
