So ive had my ipad mini for like may be 3 years and now the screen is flickering quite bad every 2 secs. it flickers for 1 secs and stops for 2 secs and continue agian. if i turn off my ipad mini for 1 hour. After i turn it on nothing happend but after 2mins into the usage it starts to flicker again. i think it has something to do with the main board being overheated or something wrong liao. can fix this and how much would it cost?
