Hello Chromforum,

Recently after performing a cleaning of my inlet and detector our 456 GC locks up upon powering on. It sticks on a black screen with the Bruker emblem. Previously, within the last week, we had an issue where our log file became corrupted, and were able to reset it using a connection from the computer it is connected to, but now it won’t get to the point where the computer can establish a connection.

I had read about this issue being caused by the mainboard battery, but upon testing it was at 3V. Out of an abundance of caution I replaced it with a new battery anyway, unfortunately it didn’t resolve the issue.

Anyone who has had a similar experience, or has any knowledge about how to fix this problem would be greatly appreciated.

Thanks,
G
