Hi all
My SEGA virtua Fighter cab with the 29" Flat screen monitor
NANAO AMUSEMENTSCAN 29 Type MS9-29SU is startet to come with an error when i power up the cab

There is a nice clear green screeen with this message.
"Warning the voltage is to low ! Please increase the voltage to 5 volt".
Nothing else happens ?
Any idea where i should start here ?
