Dears,
I am a late builder of the X0.2
trying to power up the PSU board, however VFD display does not light up at all.  Have measured the e-cap on the VFD board and get 5v & 26.8v.  seems to me the flat ribbon cable is installed correctly, without circuit diagram to verify.  The MCU is the version of photo100fun.

My questions:
Has the L & R channel board to be connected to PSU board, so the VFD would light up?  I don't see any trace of VFD is laminated.

Appreciate for any advice!
