  • With the screw removed and the display and touchscreen controller disconnected, you can begin lifting the PCB away from the NOOKcolor's display assembly. But, don't pull too hard. The Wi-Fi antenna cable is still attached to the assembly. The antenna wire runs under two thin metal plates. You can either disconnect the antenna wire and pull it out from under the plates, or bend the plates up slightly and pull the wire out. I opted for the latter.

  • "Display connector chips"

    "Display connector chips" - well it looks more like a switching power supply. Device marked "100" is an inductor connected from Q1 to rectifier D1, and note the bank of 3 capacitors C18,47, 48. Likely MOSFET Q1, and likely controller UC1. What is VR1 for? Did you try it? It would be cool to have a real close up and see the part markings on those semiconductor items.

    All that and no look at the processor.

    • RE: NOOKcolor Teardown

      @Ostracus, process of elimination says it's the "unknown Texas Instruments chip". This makes sense, given the chip's proximity to the RAM, and the fact that TI makes the OMAP ARM chip known to drive the NOOKcolor.

    Personally, I think there are better eReaders on the market. I bought my eReader after reading this fast and simple eReader report from theebookreport.net

      @dxg19, lol do you work for Amazon? ;) jk...

      I think the Nook Color and Kindle are really for two different markets. I have a Nook Color and I love it. I read mostly non-fiction and I appreciate seeing color charts/data and reading other ancillary docs (PDF and Office). I do occasionally pop over to the web for further reference on topics. So to me it's a great, integrated reading and casual study tool. I only miss being able to annotate Office docs.

      @Ostracus, I agree! :)
      My wife has a Kindle and she loves it. She reads novels, exclusively.

  • RE: NOOKcolor Teardown

    Despite the manual.. it -will- charge from a computer.. the nook color just has to be off (i.e. turn it off while it's hooked up) and it'll charge, I did this last night (wasn't trying to charge it on purpose), but it did charge. The reason why they say this, is that the 'automount' that it does of the internal storage/sd card, overrides the charging driver..

  • There appear to have been changes

    The Nook Color on which i am typing this reply (purchased August 2012, rooted shortly thereafter) has a plastic outer edge (already cracked on three sides) rather than metal.

    I wonder if there changes that are not simply cosmetic.
