Thunderbolt Display Repairability Score: 8 out of 10 (10 is easiest to repair)

Only T6 and T10 torx screws hold it together, meaning minimal tooling is required to service.

Minimal use of adhesives means reassembly will be easier and cleaner.

Front glass panel and LCD are easy to remove and major components are exposed upon removal.

You have to use suction cups to remove the front glass, which could end poorly if not done properly.

While disassembly was very straightforward, there are a lot of parts, cables and connectors, making full reassembly not for the faint of heart.
