I switched on my SV06 last night and I got a quick blip on the screen and then it powered off.  
I thought it might be the power supply so I hooked up an Allwinner 24v I had laying around and I get the same behavior. Is there a fuse on the mainboard or something I should check?

The is a fuse between the switch & the power plug. Pry off the little cover to get to it.
