Chosen Solution
Hi, I have a dilemma…I bought a second hand Apple thunderbolt display 27" for 300 euros. During the past month the each time i switch the display on it usual trip my electricity and for the past 2 weeks i heard a buzzing sound. Today the display does not switch on. Most probably the issue is with a faulty power supply. I checked that a new power supply cost 120 euros while still not knowing if that is the only faulty part. My dilemma is if it is worth the fix for 120 euros if not more and now knowing that the display is old 6 years? I found another good branded display for 400 euros. I am writing to know your opinion and hopefully make a decision myself :) Thanks btw it is a good useful site :) Jonathan
That got it: Apple Thunderbolt Display 27-Inch Specs Identifiers: Thunderbolt Display - MC914LL/A - A1407 http://www.everymac.com/monitors/apple/t… Looks like this is the power supply you need: http://www.ebay.com/itm/Genuine-Apple-27… Here’s a brand new one: http://www.ebay.com/itm/NEW-614-0510-App…
It’s an internal power supply, so that makes things a bit risky. If you are able to remove the power supply board and inspect it, look for bulging and/or leaking capacitors. If you find any its probable that replacing them will fix the issue. whether I’d go that route at this point is a toss-up. Generally electronics that last for 1 year will last for several, but the failure rate seems, (in my experience) to start trending upwards again at around 10 years.
