We have a Agilent 8453 uv spec that died after a power outage. It would not turn on. The power supply was checked to be ok. We replaced the G1103-66502 board that controls the lamps as we could see damange on a chip. Once replaced the instrument and lamps can turn on but we are getting a digital signal processor error and it seems to be no communication to the SDA board. When I go to the instrument information there is no information for the SDA board. Am I missing something with installing a new board? is there a hardware diagnostics to troubleshoot possible errors?
Could my main board be the issue even though everything turns on fine?
Thanks for any advice,
