  9. I expected to have to heat up the screen and deal with a display adhered in. I'm super happy to announce that is not the case here!
  10. The screen assembly is held in with clips! No heat, no adhesive.
    11. Step image Step image Step image
  11. Once all the clips are free, the screen opens like a book the the left.
  12. The lower flex cable for the display is on the upper left.

  13. Replacing a cracked screen requires you to remove the frame on the broken screen and using two way tape to attach it to the new screen.

  29. Can't find any reference to this Chip, ITE is all I can seem to read.
  30. SEC 946 B620 KMDV60010A GHGF689P RAM
  31. MEDIATEK ARM MT8183V 1932-ZAMAH CTPNUN82-A the CPU
    32. Step image Step image Step image
  32. MTK MT6370P 1945-ABSH ATFPX203 I believe this is a MediaTek WiFi chip of some type?
  33. MEDIATEK MT6358W 1926-ANAH CCMJ2NPS OT1342 Some sort of power IC
  34. QUALCOM ATHEROS ModelL QCNFA324 WiFi Chip

  38. Looks like some little pull tabs keep the battery in. I guess we can't have everything. But I'm happy for pull tabs and not just some adhesive I'd have to dissolve and slowly pry at. I'm going to keep this part in, since this tablet still works 100%, and I will be reassembling.
  39. The model reads L16D2P31 It is a 7000mAh
    40. Step image Step image
  40. The little pins the keyboard connects too is held by 3 little screws and looks pretty easy to replace.
    41. Step image Step image
  41. The power and volume buttons aren't even connected to the board, they use the little surface connectors.
    42. Step image Step image
  42. While I'm not office iFixt it, I'd say, in my experience I'd give this a 8 out of 10, for repairabily.
  43. On the up side, the screen is held in with clips, meaning no adhsive or heating to open the tablet, unlike what seems every other tablet I work on these days. Lets hope repalcemt parts come in the frame, not require we move the plastic frame over to the new screen. Most of the parts are modular, including the charging port and buttons.
  44. Also on the upside, all the screws are the same size, which makes for easy reassembly. The speakers are also pretty easy replace.
  45. on the down side, the battery is adhered in, and some parts, like the WiFi chip are soldered on. However, looking at this from a Tablet perspective, and not a PC, that's to be expected. It does look like it might be replaceable, even if it is soldered.
  46. I hope to provide updates on this device once I see what replacement parts are like, as well as cost.
