I picked up this monitor also in a Tekken Tag machine and it seems the fuse is blown.
I went to my local Radio shack and got some Slow-Blow Fuses. 250 vold 1 1/4 x 1/4 MDL, 3SB, 313, MDC and they blew right away. Part #270-1023.
Since these are the wrong fuses I was hoping that someone could recommend the correct fuse I require.
Thanks, -
