I had the same problem after a flight from UK to Malta, but my SDA read a constant depth of 1.1 metres and unable to access any other functions.
Tried running the battery down and re-booting, but that didn't work.
Washed the depth sensor a lot (constant running water for several hours) didn't appear to correct the problem, but might have helped.
Took it on some Tec dives to 'exercise' the sensor (I used another dive computer and tables - didn't rely on the SDA), after the third dive it started working - showing a 0.9 metre deeper reading than the other computer - As this was less than 1 metre it meant that the SDA zeroed on surfacing and the other functions were once again accessible.
On the fourth dive this dropped to 0.3 metre deeper than the other computer.
Fifth dive saw the SDA agreeing with the other computer plus or minus 0.1 metre.
It now seems to be working just fine.
