Just bought a brand new 2019 imac I powered it on, I signed in heard a pop and a sizzle and smelled something burnt and the display turned off. Will not power back on. Directly bought from apple brand new never opened and it died in 15 minutes. My question is, is there anything I can do or is it dead completely. ( I'm not bashing apple things happen) thankfully I have the 3 year warranty.
