FCB 1010...is it beyond repair?

I wonder if anyone here has had problems with their FCB like I am having. I just picked up a used FCB and I program it with just note messages, on channel 16, however it likes to send other CC messages on channel 1 randomly and also the note messages assigned are working with the wrong pedals! (not the ones I assigned them to)..I did a factory reset, and am quite familiar with programming using the Mountain editor. I have another FCB that I have used for years and it works fine. It seems like a hardware problem. Any information or suggestions you might have are greatly appreciated. Thanks. Oh yes, and it has a stock EPROM chip.
