help, i lost my picture on my monitor

[notaburger]

alright, i was trying to rehook up my arcade vga and i think i wired the breakout cable wrong
i was getting an awful picture that was rolling and i tried to fix it with the knobs and it didn't work
so i unplugged it and rewired it
the second time i accidentally wired the ground to the v/h sync
now i'm getting nothing
it's turning on but no picture at all
i even tried hooking up the old connections to the arcade and nothing
does anyone have a clue what i did and possibly how i could fix it?
i'm hoping it's just a fuse or something
thanks
