My plug died today (about 9 months old) - the LEDs don't light up. I opened it up and checked the output of the power supply with a voltmeter and it seems to be delivering about 4.8V fine. So that doesn't seem to be the problem.
Does anyone have any other ideas what it could be, or how I could check?
EDIT: I noticed that when I flick off
the power, the LEDs would light up for a second. When I was checking with the voltmeter, the voltage would die down then spike up to over 5V for the same time, after turning off the power. So it was
the power supply after all. I wired in an old wall wart and the plug lighted up. Phew!
Someone should design a new casing for all of us with dead power supplies. A plug with a plug looks ridiculous!
