Attempted to do the Ultimarc video amp mod. I have a Ducksan/Samsung style monitor and hooked it up like in the picture. I cut the trace for H/V sync and I get no picture at all. Any ideas? The original cable was actually spliced together with the lines running into the amp and this.
If I tested the correct pin it doesn't look like 5V is coming off it. I'll start there.
Someone must have modified my game along the way because the VGA cable was spliced together with the 6 wires that I fed into the amp from the picture above. On the board connected to the monitor, the pins were labeled H V E R G B. I guess E is ground (earth)?
And I thought it was going to be cake since someone had already provided a convenient way to tap the wires into the amp.
Mine are white, check the manual. Googling that part number took me right to Marcos, listed as white: http://www.marcospecialties.com/pinball-parts/20-10110-5
