Funny, mine just quit working a few weeks ago too, they must be in kahoots! Mine doesn't power up at all. It's getting power at the board and that's as far as I've had time to go. To take it apart, there are two screws in the battery compartment, and one more under the little blue label on the back. You don't need to remove the larger black label on the back. With those three screws out the main case should come apart. There are more screws and stand-offs inside on the circuit boards.
