Topic: Chumby Guts not working

I've been using the Chumby Guts, available on Maker Store, for more than 2 months approx.. I usually keep my chumby powered on and haven't faced any problems.

But, yesterday it just didn't respond after I powered it on. All I have is blank screen. Don't have any idea on how to debug it. Power adapter is working fine. There are no signs of heat or smell in the guts.

Please help! Thanks!!
