Where could one find such a power supply for the 4th generation Apple TV. Sadly this one went out without even a years worth of light use.

Lewis,

If its under a year just have apple replace it. I just replaced the powersupply with one I aquired on ebay. It didn’t power on when I was done with the fix. I didn’t go all inspector gadget on it, but with the plethora of heatsinks on this thing I bet some circuitry fried due to a heat issue.

This instructions were perfect. Found power supply, replaced in about 15mins. Apple TV powers up again. Saved me from buying another.

THANK YOU
