I've been doing the Soft Resets and still have the same problem. Should I do a Hard Reset?

Could this be another power supply issue? I don't want to change the power supply for a new one only to have the same thing happen. Was wondering if anyone's seen their Monoprice converter develop this symptom.
Swapping the wall warts between BR & LR ought to tell you if it's a PS problem, if they're both 5V 1.0A, which is typical for these.

I don't remember if any of my converters ever had symptoms like you see, but I have had multiple wall warts go belly up. I successfully fixed at least two, at least one of which did come from Monoprice. Those wall warts are made with junk brand caps that can be expected not to last in continuous use. I also bought a replacement wall wart from Mouser in December 2014 that still works. Caps for repair came from Mouser and/or Digi-Key. I used 470uF 16V 5mm or 470uF 16V 3.5mm from Mouser in at least two of those I fixed.

How I got them apart I don't remember any more. I may have found some instructions on badcaps.net. I used rubber bands to super glue them back together after testing to see the repairs worked, but tie wraps should work well enough too.
