Got an iMac that thunderbolt is not working. Opened up iMac and discovered a noticeable burn in the thunderbolt IC U2800. The part number is DSL3510L and I have this same IC on a donor 820-3437 MBA L2013. My question is, is it even possible to replace the Thunderbolt IC, or is the firmware paired to the CPU somehow since it uses PCIe lane.
I have attached an image of the burn in the thunderbolt IC.
