Apple Thunderbolt Display Power Supply Replacement (Buzz Kill)

Il Mio Problema

My Apple Thunderbolt Display was buzzing for a couple of years. At first it was slightly annoying, but lately it got really loud, to the point that my wife noticed it walking outside my home office.

La Mia Riparazione

I ordered the Apple part number 661-6048 power supply (google it, there are lots of vendors), followed ifixit's instructions and in short order I was buzz free.

Il Mio Consiglio

Be very careful with disconnecting the cable inside, use a spudger and squeeze the connectors to release the locking tabs. The locking tabs are hard to see on the circuit boards as they are facing away from your view. Use a right angle or short torx T10 driver to get to the cable connected with a screw.
