Hello all, just received the Meter module and I'm very happy with it, but there's something about it that I do not understand. Sometimes, when I power on my system, the upper half of the screen remains dark. The lower half the screen will work, but the upper half is just blank. This has happened a few times, and usually if I power cycle the system the module will activate and work properly. However, I'm worried that there is something faulty with the unit, and that over time the situation will deteriorate. Do I have a faulty unit? Is there anything I should do?
