Topic: Boot screen on C1 fades to white

I had to powercycle one of my C1s yesterday... and it never came back :-(

I get the circle screen and then I get two wide bands across the screen and it slowly it fades to white.

I've made a video (20 seconds) of the boot sequence: https://sweh.spuddy.org/tmp/nonbooting_chumby.mp4

Any ideas?

Looks like c1 power supply capacitor failures..

Cleaning up any loose bits and bytes.

Re: Boot screen on C1 fades to white

I tried powering it with a different power adapter (from the chumby that's still working) and got similar (but subtly different) results.  So it may be power adapter related and both are marginal...

So I tried it with a generic RadioShack power adapter set for 5V 2.5A (the barrel wasn't quite wide enough and wobbled a little, but it made contact) and got exactly the same results as in my original video.

So I don't think it's the external power adapter at fault...

I've got the same issue now after a power outage. Did anyone find a solution for this problem? Mine boots up the same way with the fading white screen.

The "fade to white" screen is a typical bad power supply symptom.

Thanks Duane! I will do some research to see what can be done to fix this.

This is the definitive thread on C1 power supply issues.

If you don't want to buy one, just find another some other 5V 2A power supply (very common nowadays for micro-USB powered devices like Raspberry Pis, etc), and graft the barrel connector from your existing power supply onto the new one.

It looks like the Chumby Store shows them out of stock, but I'll check to see what we have and adjust accordingly.
