The New TV: Strike 2

I got the replacement TV. It turns on, but it also shuts itself off within 45-90 minutes after it's turned on. (No, sleep isn't on. I am at least that tech savvy.)

It was only dragged up 5 stairs on a dolly. I suppose that's why it only slightly malfunctions. How many TVs need to be delivered to get one that works? Seriously, nothing should be this hard. Sigh.

(It's lovely though. I just wish it worked properly.)
