BV Pulsera starts with Viewing station in standalone

Lost connections from MVS to C-arm Stand. You need IST and BV Scope softwares to reconnect it. 

it's intermittnet.  maybe 1 out of every 10 restarts, it boots normally.  this led me to think it was a connection or some missing signal. 

(having trouble registering IST, so I'm trying to look for any solution that doesn't involve using service mode)

Try flexing the umbilical cable. Also try putting a monitor directly onto the DVI.

it's looking like the cable or connection now.

user reports he can get it to turn on if he "fiddles with it" while pressing ON

The cable isn't horrible to change. Just make sure you get a new one. Otherwise you will be facing the same problem again in the future. There was an FCO fir the cable years ago. Make sure if you do not already have that done that you do that as well. Let me know if I can help.

Error m040

Communication problem between the c-arm and the monitor cart could be still the cable try moving the cable again and see if the error goes away

We think we've isolated it to K4 on Wa1 board.  It's responsible for the STAND ON voltage.  Only thing is, we can't find anywhere in the manual which of those 10 relays is K4.  Anyone have a breakdown of this board?
(it's the newer style with 2 rows of 5, not all of them in line)

I have ever repaired so many times about this problem. Normally, It was lost Serial Number of  DFI or Stands. Somes case come from the software of DFI. Please tell me software for DFI on site.Is It  bellow 1.7.2 or 1.8.1?
