Defcon 20 Badge question

Yes, DC20. I recently was able to get an older badge from someone, because it wasn't working well. When they put batteries in it, the switching regulator (U7) started to bubble and smoke. from the other main DC20 badge thread (http://forums.parallax.com/showthread.php/141494-Article-Parallax-Propeller-on-DEF-CON-20-Badge-Start-Here!) on post #37, someone else seems to have the same problem, but no response was given. Is there a way to bypass this or replace this chip, if it's not needed?

Thanks!

    It's a manufacturing/design issue with the buck-boost power supply system. It's going to be more practical for me to replace the badge for you. Send it in with your return address:
