Does not start up. Shuts down when disconnect
These are the symptoms: the iPhone does not turn on, just only when connect to wall or the computer. Itunes does not see it. Stuck on Apple logo then shuts down. Shuts down when disconnect too.
I have isolated the problem and I guess is the logic, since the dock, battery, headphone and LCD are ok. I can to put in restore mode, but Itunes does not recognize it. Any ideas?

Since you already did all your trouble shooting and looks like you really need a new logic board, try here http://iphonepartspro.com/iphone-3g-16gb...... pretty costly but at least its available. Good Luck

Only other choices are micro soldering once you determine where the break in circuit is. If you've got the time, equipment and skills... Take a look at the bottom right if the board where battery contacts are- I've found quite a few boards with tiny fractures of gold wiring from this area, I'd think people are pretty brutal trying to get the board/antenna out with battery change. If you can see the break try scraping a bit of the "varnish" up to expose the metal and then make a solder jump over the break. I'll see if I can find a link that I found useful.. Looks messy but it worked for me!
You've tested the battery? Is it a new battery ... Might want to try another one as some oem fail to be recognized by iPhone
pollytintop,
macpatagon, I am with pollytintop on that one (and pollytintop knows iPhones) change your battery first. You said you isolated the problem, how did you do that and why do you conclude that it is the logic board? Replace the cheap (battery ) first....:)Good Luck
oldturkey03,
I guess is a logicboard related issue, because I tested it in another iphone and the same issue ocurred. If I put a good Logicboard in the iPhone with the new battery everything works ok.
macpatagon,
Have you connected the new battery to the "old" logic board as well?
