Unfortunately Olevia doesn't have a good customer service reputation. We had a warranty that guaranteed onsite repair. (We had one that the sound went bad at about 8 months.) They were impossible to get on the phone and when we did after long wait times, they would tell us to call back.
We weren't the only ones, if you look at the reviews on Olevia's on Amazon, you'll see this is common.
Anyway, we purchased the TV at Meijers and they found out for us that our particular model was recalled and agreed to let us exchange for another brand. I would never buy another olevia personally.
Hope this helps.
