The deal was for the display model so my bet is you claim the warranty as it's new and you just registered it and your receipt is one week ago. My bet is they'll sell you a new one for the new price.
About a week ago I bought a display model OLED TV from hhgregg specifically the LG 55EF9500. when I got home I noticed the tv had the burn-in of the LG OLED logo. I didn't notice it in the store because the tv was playing dark content which masked the burn-in. I did get the extended warranty since it was a display model, but now I am wondering whether to return it back to the store or use the warranty for a repair/replacement of the TV. I would like to know if I return it to the store will I get a refund for the warranty and/or if they would replace the TV at the same price. I am not sure what to do so any suggestions would be helpful.
Thank You!
