Replacing the Logic Board of your iPod

When your iPod was young, did life seem so wonderful? A
miracle? Was it beautiful? Magical? That’s because the logic
board was working perfectly. But logic boards are components
like any other, and they go bad from time to time. If yours is
making you clinical, cynical, or fanatical because it’s not so
logical or dependable (in fact, it’s a vegetable), replacing the
logic board is the cure, as we show in this chapter. The cure
to Supertramp, however, we have not yet discovered.

Check the Signs of a Bad Logic Board
The logic board is the brain of your iPod. No joke—your iPod is a miniature
computer. The logic board contains the microprocessor as well as the connections
to the various other components and systems: the battery, the hard drive or flash
memory, the display, the audio, the data ports, and so on. If something goes
wrong with your logic board, it’s not unlike massive head trauma in a human.
A bad logic board reveals itself in different ways. Your iPod might not turn on,
even when you plug it into a charger. If the iPod does turn on, it might show the
sad face or the folder icon, or it might freeze on the Apple logo.
It’s hard to diagnose a bad logic board from the symptoms alone, because
they’re the same symptoms that you get from other problems. Before you
decide that the logic board is bad, be sure to rule out other possible causes.
For instance, if the iPod doesn’t turn on, check out the battery, or if you get
the folder icon, you might want to look into the hard drive or the software.
Restoring your iPod in iTunes might do the trick.
When you’re reasonably convinced that the other components are in good
working order, the logic board looks more and more like the culprit.
