New post old problem. I have a arrow 750 with a acramatic 2100 control. Startup shows shows "internal error SEV_SYSTEM_FAIL_CHANNEL_ID the error is 0x80016. I also get a system fail 4000f. My DV5 board shows fault. Bridge board lEDs come on and go off like it should. No software loads. Windows NT loads. WS CPU is 3-424-2290a02,
RT is 3-424-2171a01. I replaced batteries in both boards. Voltages were around 2.5 on each. Any help is appreciated.
