Hi! I dont have a tech background, so please pardon if I make a mistake. I have a Ipad pro 9.7 inch 2016 model A1673 which just stopped working one day. It wont turn on, I tried many tricks ( other than opening up the Ipad) that was recommended by online forums but nothing worked. I dont have any apple care or any other plan on it. Is it worth taking it to a local repair shop ( apple said they will charge 799$ to replace it). Is the life of an ipad 4-5 years only? Thanks for your advice.
