Looks like both your CPS2 and MVS are malfunctioning. The actual monitors look fine on both.
Check 5v on both cabinets, with the PCBs connected, measuring at the Jamma edge. Adjust the PSU getting it close to 5v, I usually go for 5.05v at the edge with a game connected. Whenever you swap out PCBs you should always check this.
Check & clean the cartridge and slot contacts on the MVS.
Reseat the CPS2 A+B boards, making sure you use a little force to fully connect each of the 4 connectors.
