Seems like my eTrex Vista Cx kicked the bucket, but I thought I might see if anyone has ideas on maybe getting it running again.

I used it about a month ago with no issues, then went to use it yesterday and found that it wouldn't turn on. Multiple sets of batteries and multiple USB power cables with no luck. Dead. Would not respond to master reset button combination either.

I thought it might be a bad power micro switch, so I pulled the unit apart and probed the micro switch. It appears to be functioning fine. I also checked the voltage of the button cell battery and it was 1.5V so it seems to be fine...I'm not sure a dead button cell would cause this issue or not.

Any other ideas?
