Q: How to degauss Apple Thunderbolt Display

Hi everyone,

I have sold my Apple Thunderbolt Display and it was shipped via DHL to its new owner.

He claims now, that the Display is broken. He sent me two pictures where a thin partly green and violet line can be seen around the display.

After doing some research, I found this degaussing issue and I wonder if that's the reason for the problem as the monitor was absolutely fine before I packed it for the shipping.

Here are the photos he sent me

Thanks everyone for your feedback in advance. It's much appreciated !!!

Greetings,
Melanie
