Chosen Solution
Dear experts, I have an A1502 board from a MBP retina early-2015 with the U2800 chip completely removed by a repair shop that couldn’t fix the issue. PCIe U2800 chip details (written on the chip): i MC 13 Z636TA341 The issue was artifects on screen for a few days and ultimately no life at all (no fan spin, just green light). This doesn’t seem to be a normal soldering chip and rather difficult with BGA/reballing? Thanks for the help, Nick
