hi guys

Recently I've noticed that my RU990 resets itself occasionally when picked up, I've tried but can't seem to find any pattern to it.

I've tried what Philips support recommended, updating the firmware, resetting the unit and redownloading the PCF but it's still happening. I even tried creating a very simple PCF from scratch to rule out the possibility that imported 'rubbish' was causing a problem.

Is this a known problem? Or is my unit likely to be faulty?
