Remove the T8 Torx screw securing the metal shield to the case.

In order to remove the T8 screw, you must insert the screwdriver through the access hole in the metal shield, located near the PRAM battery.

Remove the T20 screw securing the metal shield to the case, located near the digital audio port.

Lift and remove the metal shield away from the upper case of the Apple TV.

Use a pair of tweezers to pull the IR cable straight away from its socket on the logic board.

Make sure to pull the connector parallel to the face of the logic board, not straight up from its socket.

Lift the left edge of the logic board (nearest the PRAM battery) upwards and slide it out of the case, away from the ports.

Be careful to not damage the ports when sliding the logic board out of case.

Logic board remains.

Carefully peel back the two copper sticky grounding strips near the LED module.

Swing the outer aluminium case up and carefully slide it towards the connector side of the logic board until it comes off. Remove the two Phillips #0 screws securing the LED module.

Carefully unplug the module from the logic board to make it easier to work on, and remove it from the case.

There are two miniature SMD LEDs, one is clear and one is yellow. Unsolder the yellow coloured LED, which is actually the white one - the clear SMD LED is amber when on. Replace with another high intensity SMD LED. I used a blue one to match my other hi-fi components. The anode (+) is marked on the circuit board and is away from the infrared receiver side. Reassemble is a simple reversal being sure to remember to reverse every step.

SMD LEDs are difficult to find as a spare part. I carefully ground down a normal sized LED with a Dremil until it would fit. The only source of SMD LEDs I could find was LED bar lights in various colours such as these: http://www.jaycar.com.au/productView.asp...
