I've been trying a couple of the different images as well, on two different boards, using different SD cards from different manufacturers, and things seem to be the same so far :/ One thing I've noticed is that it apparently does _something_, because it will wake up my LCD monitor occasionally, but then the monitor complains of no signal. The TV doesn't do anything though.
Also thought it might have been the power supply I was using, so I've also tried the super beefy one from my S5, and it didn't make a difference either. Also doesn't matter if the keyboard or network are plugged in or unplugged, etc.
Also tried the standard Linux xwindows shortcuts -- ctrl+alt+backspace to try to restart the GUI, ctrl+shift+f1 through f10 to switch to a console, etc., but nothing :/ Even tried a USB to serial adapter, since my odroid will only output video when it's got a serial terminal connected (due to the settings I put on it to save power.) But that didn't do anything either.
I'm starting to wonder if maybe the design was a dud or something, which I guess would explain why they're going for $5 on eBay and why the moderators don't seem to be active on this forum. Which, in reality, if that is the case, I guess that's ok because they would make ok headless server boards, but it would have just been nice knowing that at the time instead of hoping to be able to read sensors or use them as serial dataloggers, etc...
Also, I'd love to get a Debian or openSuSE image for the boards. But I'm not holding my breath on that one... Maybe I'll try my luck at doing a custom image eventually.
I am curious though -- Did people like Mike actually get a display to work with their pcd8? If so, what image are they using, and did they have to do anything special? If it makes any difference, my boards are listed as revision 1, mfg in Sep 2015.
