I managed to resolder the caps last night and then get the rest finished up according to the instructions. Initial power test was fine: on/off switch worked, and the LED lit when power was applied.

I then mounted the ICs in their sockets and plugged the thing into a LCD monitor and a USB keyboard with USB to PS2 converter.

Unfortunately, there was no signal to the display. Power at the 5v voltage regulator is fine.

So... tonight I'll try some different displays and if that doesn't work, I'll start checking the board for potential bad solder joints. If that doesn't lead anywhere, I'll go begging for help on the Briel site.

I'll post a picture or three now.
