Xumo box not working

Xumo box worked and then I leave for a few hours - and I come home the box is off and when I powercycle the unit it turns on, I get the "Hello" screen, it changes to the Xumo logo spalsh screen and then immediately shuts itself off again. Now I can't make it work at all! If I remove the power supply and plug it back in, the box works for a few seconds then the power light begins to flash, then it shuts off. I tried moving it to different outlets, I reset my cable modem just for fun, but the behavior continues. I’ve tried new HDMI cords, changed outlets everything.. most I get is the Hello Hola screen.. the Xumo Play logo.. and then.. signal goes off on TV and I get the smart tv notice to check connection because there's no signal coming from the xumo box to the tv. I am beyond frustrated. I also spoke with Xfinity support (that's 3 hours of my life that I'll never get back) they went through some basic troubleshooting but couldn't resolve the issue. So now I have an appointment scheduled for a grade 2 tech to come to my home and troubleshoot and bring my 7th xumo box. Not high hopes for a resolution. I even tried the trick of holding the home button on the remote while pushing the two arrows on the back side of the Box trick and it didn't work because I'm not using Wi-Fi I'm using direct Wired from my modem so that didn't help and now the remote doesn't work at all. I tried resyncing it with my TV but that doesn't work if you can't get to the settings of the xumo box because the xumo box won't stay on. I am seriously ready to throw this xumo box in the trash and forget it. None of the xfinity customer service agents ever help all they do is laugh at you, lie to you and then want to change your services all around or try to get you to order there mobile services. Useless waste of my time.
