During my annual service the SC tech noticed that my MCU had the "yellowing" issue. Frankly I had not noticed but they said they would replace it and its on backorder. Question, I'm wondering if now the factory have switched to the new Intel MCU v2, that they will just replace this with an updated version? Or do they just replace the screen? During the factory tour I noticed a whole pile of MCUs and it looked like the screen and CPU components were pretty much one unit. Anyone had this replaced recently?
