Topic: test points on my dead Chumby?
Hi. I have limited knowledge in electronics and i could really nedd some help in diagnocing my dead Chumby.
The screen is dead and it does not show up on my wavelan router. I have no jtag cable so i'm not able to look at any boot messages either. The Chumby is now naked and when i put the power plug in all the big hynix ic:s ges warm, the u601 gets very hot and have voltage between Vin and gnd. 5V regulator U501 also have voltge between Vin and gnd.
What's the best way to diagnose what is wrong with my Chumby? I see a lot of test points in the scematics but i don't know how to make use of them.
Since i live in Sweden i got no warranty and i really want it back alive. Can you guys please help me?
