Ok, so the power and and the memory are fine (or we can assume). Maybe your earth isn't very good. Maybe try another place.

I had the same problem when I bought a 450 PS 60mm Apexi power meter Gauge 2 years ago. Now this is an old and rare gauge and it would be a novelty in a Supe.

 

Due to its age, I found that I had to strip the whole thing and re-solder it as it was built a few years ago when they didn't 'dip' the gauges in to soldering solution to make a permanent contact for the circuit board.

 

It's working now but it may be an internal connection problem in your case if you have already tried the other points that the boys have mentioned so far.

 

If nothing else works then I would suggest that you take the back off and ensure that the +ve and -ve circuit points that connect the main power leads to the circuit board are intact
