I have a Pam 090 power reserve. Worked great for a couple months, now it doesn't work. The power reserve is still up but the seconds do not work. Had someone look at it and they said it was missing a screw and he couldn't get it? Is there anybody in the Cincinnati, Ohio area who knows Pam's who may be able to look at it or if anybody knows of any reputable person? Thanks guys, look forward to hearing from you!
