WTB: WMS BB2 Backplane 6779-006672-04-00

Looking for a fully working backplane (Blue) for my BB2E 6779-006672-04-00.  Serial communication must be working, as that is the only issue with mine, I can't use my TITO.

Thanks

Thanks again to NLG member Eddiie for helping me figure out the issue with my Tito, I was using a USB port on the CPU unit to power the Tito, that was causing the five volt regulated power circuit to disable itself.

Sorry if this has already been discussed in the forums, but for Serial Comm to work, you need the 5Vi  line working.   Make sure the LED is lit on the backplane.
Lower right corner of the backplane..  Further down from the other power LEDs..  A little lower..

Yup, I posted about my issue in the Williams forum, but haven't had any responses.  My Unregulated 5v led is lit UNTIL I plug in the Tito, then the light goes out (unplug it and light turns back on).   The power supply is supplying the correct voltage, and I even ran 5v direct from a switching power supply, same result.  I can't find anything online regarding this issue so I'm basically hoping a new backplane solves the issue.
