Troubleshooting MiniPac Shifted Problems

[newoski]

UPDATE: I've somehow solved the problem. I believe this was a freak thing... The inputs that stopped working were shifted functions for Vol Up and Vol Down. I believe the functions stopped working in Windows, and therefore, with the MiniPac. They still don't light up in WinIPAC, but they work just fine in windows...

Hi Guys

Things have been working great with my MiniPac and ServoStiks the last few weeks. Then, out of nowhere, breakdown...

All standard functions still work fine
Most Shifted buttons work fine
(Shifted) P1 Up and P1 Down & P1B1 & P2B2 do not work
The LED diagnostic flashes once on boot and then stays solid

I've also tried swapping out a spare MiniPac -- using the same wired connections -- with no change.

What steps should I take to diagnose?

Thanks,

Owen
