Bu Teardown'da Kullanılan Aletler

Giriş

I teardown a common DTV converter to see whats in it and debunk the "camera" nonsense. This little box has 16MB of RAM and an unknown speed CPU. Well, lets find out!

Bu teardown bir tamir kılavuzu değildir. Access HD Digital Converter cihazınızı onarmak için, servis kılavuzumuzu kullanın.

Ah, the tiny little box. Reminds me in size of the new Apple TV. Yay for cheapo silver paint. What do you expect for 20 dollars?

  • To open it, you must remove 3 screws. 1 on the back, and 2 on the bottom behind rubber stickies.

  • There is also 1 clip you must undo on the back, it's visible.

  • The device takes OTA digital signals and converts it into analogue 480p. Ironic that it's called Access "HD". Composite or coaxial are your choices here.

Once the cover comes off, you must disconnect the front button cable.

  • The front button board does not have much on it. Buttons, 2 color LED and an IR receiver.

  • The Motherboard only takes up 2/3 of the case. The rest is empty plastic!

  • Unknown CPU with a clock of 100mhz and 16mb of on board RAM. Contains a composite video encoder and some kind of simple video controller capable of 480p resolution.

  • 4mb Flash DRAM which contains an unknown simple menu driven OS. No advanced features whatsoever.

  • Composite video output, Power in jack

  • RF Transceivers

  • Not much to this little device. It works well at picking up free over the air television. It tends to run hot, so the CPU must not be well designed for such a simple task as decoding MPEG4 streams.

Taking the top off a product is not a teardown. :(

I have 2 decoders that have failed,,this is one of them. Seems to have power but doesn't decode. Need to know how to test parts and replace.
