So I pulled an old mx-880 out of a drawer to use to replace a failed mx-780. Put a new battery in it, charged it up and put a simple program on it.

When it hits the first variable in a true state the remote hangs. I looked at the program and it looked fine so I put the program on a different mx-880. Works fine, no problems. Put a different program on the questionable mx-880 and still has issues.

So there is definitely an issue with this particular mx-880.

Has anyone seen this before? Is it fixable?
