  • Apple TV completely disassembled

    iTunes users rejoice. Gone are the days when you had to watch that "Lost" episode you missed on a puny 19" computer monitor. The Apple TV lets you experience your favorite iTunes music, movies, pictures, and shows on your widescreen television.

    The Apple TV is an extremely thin, set-top media player designed to link your computer running iTunes 7.1 or later and your television. The media box offers component and HDMI outputs only--no s-video or composite. You'll need an enhanced-definition (ED) or high-definition (HD) widescreen TV capable of 1080i, 720p, 576p, or 480p.

    But what makes Apple's latest creation tick? How did Apple fit everything into the Apple TV's skinny case? Come along as we crack open the Apple TV and find out what lurks inside.

    Note: This gallery was originally published on April 6, 2007. I am resurfacing it as part of our coverage of the 2nd generation Apple TV--released in September 2010.

  • Rubber pad covers Apple TV's base

    The Apple TV's entire base is covered with a rubber pad. You must remove this pad to access the case and hard drive screws.

  • Peel back and remove the rubber base pad

    To remove the rubber base pad, use a flat head screwdriver or similar device to gently pry up on one of the corners. Then, gently pull the pad away from the metal base plate. You can separate the pad from the plate without damaging either part.

  • Rubber pad removed - Base plate exposed

    Removing the rubber pad will expose the Apple TV's metal base plate. The base plate's main surface and edges are vented. I assume this is to improve airflow through the unit and assist with heat dissipation. As the rubber pad covers the entire base plate, I'm not sure these vent holes actually do any good. I guess that's a question for Apple's design engineers. Perhaps the holes are just there to reduce the base plate's weight.

    Most of the adhesive used to secure the rubber pad will remain on the metal base plate. You could clean the sticky substance off, but I recommend just leaving it alone. It will help hold the rubber pad in place when you reassemble the Apple TV.

    If you do decide to clean off the adhesive, wait until the unit is completely disassembled. It's probably not a good idea to spill solvent on the Apple TV's internal hardware.

  • Case and hard drive screws

    The metal base plate contain eight T8 screws. Using a Torx bit, remove the four outer, case screws.

    We will remove the four inner, hard drive screws once we have separated the base plate from the Apple TV.

  • Two long and two short case screws

    There are two 10 mm and two 15 mm T8 Torx screws holding the base plate in place. The longer screws are located at the front of the Apple TV and the shorter screws near the back.

  • Carefully lift the base plate

    After removing the four case screws, gently lift up on the base plate. The hard drive is still attached to the base plate, and you must disconnect the drive ATA cable before completely removing the plate and drive.

  • Disconnect the hard drive cable from the main printed circuit board (PCB)

    Gently, but firmly, pull up on the hard drive cable's blue pull tab to disconnect the cable from the drive. This tab is a handy feature I wish all hard drive cables had.

  • Apple TV internal hardware and hard drive exposed

    With the hard drive cable disconnected, we can remove and set aside the base plate. You can see the hard drive and cable are still connected to the plate.

  • Hard drive still mounted to the base plate

    We can now remove the hard drive and cable from the base plate.

  • Remove the four hard drive mounting screws

    First, flip the base plate over and rest the drive against a flat surface or hold the drive in your hand. Remove the four T8 screws that secure the hard drive to the base plate. Then, disconnect the ATA drive cable.

    According to Apple Web site, the Apple TV's 40GB hard drive will store "up to 50 hours" of video.

  • Protective hard drive pad

    The Apple TV's hard drive is separated from the metal base plate with a sticky, green pad. I assume the pad serves to dampen vibration from the drive and absorb any external shock.

  • Peel away the hard drive pad

    To remove the pad, gently lift it away from the drive. If you ever replace the Apple TV's hard drive, you'll want to reuse the pad.

  • Apple TV with the hard drive removed

    Removing the base plate gives us our first look at the Apple TV's internal hardware. You can clearly see the main PCB, power supply, cooling fan, system battery, Wi-Fi card, IR receiver and status light PCB, ports, and hard drive interface.

  • Yellow tape holds wires in place

    Several pieces of yellow tape are used to hold internal wires in place. To fully disassemble the Apple, you must remove this tape. I was able to gently remove the tape and reuse it during reassembly.

  • Power supply unit (PSU) - Still inside the Apple TV

    The Apple TV uses a Delta Electronics Switching Power Supply (Model: ADP-36BF A). The unit converts 100-240V ~1.0A AC to 5V 7.2A DC. The unit is wrapped in flexible, white plastic (held on with yellow tape), but the ends are exposed. Watch your fingers!

  • Delta Electronics cooling fan (Model: BFB0605LB)

    The cooling fan was next on my list of components to remove. The Apple TV's Delta Electronics cooling fan (Model: BFB0605LB) is held in place by three rubber posts and a piece of yellow tape. You do not actually need to disconnect and remove the cooling fan to remove the main PCB from the case, but I wanted to see what was under the fan.

  • Remove the brace screw and case screw post

    Remove the brace screw/case screw post from the end of the bracing bar. This post uses a slightly larger Torx bit than external case screws. I believe it requires a T10 bit.

  • Remove the hidden brace screw

    Another T8 screw hold the other end of the brace to the case. You can access this screw using the small hold in the brace directly above the screw's head.

  • Apple TV top cover metal plate - Thermal paste

    A metal plate is attached to the inside of the top cover. The main PCB and other internal components mount directly to this plate. The Apple TV's CPU and GPU use this metal plate as a heatsink. This photo show the thermal paste that remained on the plate after lifting away the main PCB.

    Unless you can replace it prior to reassembling the Apple TV, do not remove this paste.

    According to various reports, the Apple TV's Broadcom Wi-Fi card is the same wireless card Apple uses in the Mac Pro. According to Broadcom's Web site, "The BCM94321MC reference design enables manufacturers to incorporate draft-802.11n Wi-Fi capabilities into notebook PCs and other devices that support the new PCI Express bus architecture. The reference design integrates Broadcom's new Intensi-fi solutions, including the Broadcom's best-performing 802.11 radio (the BCM2055), and 2.4/5 GHz baseband and media access controller (the BCM4321)."

  • Intel CPU

    Hidden under all this thermal paste is the Apple TV's Intel CPU. Unfortunately, neither Apple nor Intel has publicly announced the exact CPU used in the Apple TV. Various Internet reports speculate that the CPU is a an Ultra Low Voltage Pentium M based on the Dothan core, a Core 2 Duo Mobile variant, or a Pentium M-based "Crofton" CPU, based on SSE2 Dothan model 7645A966 0159.
