Hello,

I've never had this problem prior to moving into a newer (old) home. The first couple weeks, I have had no issues at all. But all of a sudden, these last couple days, have been terrible. I have one plp2000 in the my gaming room, no problem at all in there. The one I am having a problem with is in my living room. It randomly turns off, acting like it isn't getting any power, no LEDs, nothing. Nor will the extra outlet feature work. I'll unplug it, plug it back in, nothing. Do it again, nothing. And so on until it turns on. Then it works fine for about 20 minutes to a few hours, then just turns off. I've tried the only both of the only convenient outlets in my living and room and it's the same thing. 

It worked perfectly for two years in my old house (Besides the occasional reset). Then acted perfectly fine for the first couple weeks here! All of a sudden it has started doing this thing where it acts like it isn't getting powered. Like I said, no problems with the other one. We got a new couch recently and moved some devices around, but I'm not sure what's causing it to do this. Maybe it's shot and I need a new one?

Has anyone experienced this? Or any ideas what could cause this?
