Hi all, Today, I found a 19V power supply plugged into canevas. Canevas is designed for 12V, so I plugged in the 12V supply (which was lying next to the 19V supply - they have identical plugs). Perhaps unsurprisingly canevas now refuses to turn on. I have left it on the project bench, in hopes that someone with electronics skill feels like looking at it. [DJA]
