I have a machine here with 30k hours, pulled for a BP module that was not working properly. When I turned it on this morning, it is a completely black screen, but I can hear the UI/MICS board fan working. I have changed out the UI board and Function board, reseated all connections and exchanged out the wire connecting the function board to the UI board. Any other ideas here? Been working through the TS manual for a while and made zero progress because my problem doesn't really exist in the book. Thanks in advance

Did you work on the machine yesterday? I assume the machine made it through heat disinfect OK.
I would try a new power logic board. The black screen section of the troubleshooting guide is very lengthy.

This is going to sound crazy, but when I removed the blood pressure wires from the back of the machine, all the problems went away and it booted up fine. Thank you so much for your time and suggestion.

I came across the same situation. I disconnected the blood pressure wire also replaced all the boards and still nothing. Any other suggestions?
