mv-1fz consolized display is too dark

[kalice]

Hello, i tried to consolize this board with cmvs-rgb v2; i used av 8 pin connector but on a plasma screen the image is flickering and on a philips consumer crt the image is very dark (by the way on this display also supergun is very dark). I tried also it on an old 32 lcd samsung display but it is completly black.

an amplifier?
wrong way, arcade pcb's put out higher levels than scart/tv standards.
you need to reduce the signals with resistors to prevent overloading the tv - specially with SNK boards, they are the worst for this problem

Agreed. I just got a Chinese MVS and had to check the voltages were below 1v in case it damaged an OSSC.

so only 75ohm resistors on rgb lines and 1k for the sync line.
By the way, what should be the right output voltages on rgbs line for euro scart?

not sure, probably 0.7v
