I just installed the HA roms on my vs. board. I did remove the 4 caps from the board (C53, 61, 71, 78) and when I turn it on the picture is fine but all you get is a constant hum type sound. I had a Super Mario installed previous to this and it worked fine. Any areas I should be looking at?
 
hook a gun up, or ground the alarm pin and it'll quit humming.
