Before you go ripping stuff apart....try going into diagnostics and do a factory restore. Don't assume because the battery is dead or has been popped out that the system is indeed restored. You need to actually go into diagnostics and hit restore. I've had some real strange stuff magically go away on some Gottliebs with a system restore. I sort of start with this step first on a Gottlieb as I have chased my tail before on strange behavior and this worked. Good luck!
