So a few months ago I got a steal on a Thunderbolt monitor, around $600, refurbished, from eBay. The seller had a good rep so I wasn't worried. However...a few months later I'm realizing why it may have been so cheap. I've started encountering a few issues Issue 1: After listening to music for a few minutes, the audio will suddenly start to get muffled and become more and more muffled. The only fix is unplugging the thunderbolt cable and replugging it in. Issue 2: The monitor will often not charge my computer. There's really no fix to this, I just have to hope that it will start charing when I plug my Mac in. Any ideas on a potential fix or culprit? It was refurbished from eBay, I highly doubt there's any Applecare left on it. Thanks!!!
