“How long is the refurbished product covered under your warranty. I have had this TV for a little over a month and when I came into my office this morning, it wouldn't turn on, even after unplugging and changing batterys in the remote and trying the side control panel, it won't turn on. Normally refurbished products aren't a bad idea because you replace the weak or failed componets. In the event that it does fail again, how long do I have to return it for an exchange, service or like product?”
