So, I just ran into the exact same problem that you described early on. Powering on my ICS64S board doesn't even "flash" the monitor. Nothing happens at all. I pulled the monitor cable from the ICS64S board while the power was on and I had a IEC connector touch the board at the same time (I have the ICS64S board sitting by itself with no case). Normally this is not a problem, but in this case it shorted out the video port, which has power on it. That caused the fuse to blow. Once I replaced the fuse, I got the typical "flash" the instant power is turn on, and then normal video. Check your fuse.
