This is a donation of a friend as its not working. Actually this kindle 3 stop working when booting, hence the reason that shows the booting load bar.
I tried to search for onboard blown fuses but every single fuse I found was in good condition. After that I researched over internet and found that has a debug serial port. I tried to attach my usb to serial ttl converter with a little level shifter (kindle serial port works in 1.8v) but had no luck, not even a single character was shown in my Zterm :(
I wanted to install debian to see how the display could work and some few hack I’m thinking of but being the board pretty much dead (only seems to work for its battery charging) I decided to save it for parts as battery, case, metal frame, keyboard and display seems in good working conditions (although I’ve not been able to test them properly). If some generous reader has a kindle 3 with a broken display and he/she is willing to donate it to science I’ll be more than happy to pay the shipping.
