Introduction

Well, I found this thing in the recycling. All parts seemed intact, and the first thing that flew through my mind was: tear it apart. I used my trusty set of tools, and my own self-taught mind to rip this thing to its core, even going as far as to remove the laser assembly!

Yours truly,

Jewel Gunderson.

This teardown is not a repair guide. To repair your Samsung Blu-Ray BD-JM57, use our service manual.

  1. This appears to be a run-of-the-mill Samsung Blu-Ray player, capable handling 1080p output with downgrading for DVD's, plus a few smart features. This appears to be a run-of-the-mill Samsung Blu-Ray player, capable handling 1080p output with downgrading for DVD's, plus a few smart features.

  2. Nothing on the bottom or the front that hints at how to crack this #!@$% thing open! (DIY cussing. Let the games begin) Nothing on the bottom or the front that hints at how to crack this #!@$% thing open! (DIY cussing. Let the games begin)

  3. It appears to have HDMI, Ethernet, and Coaxial "Digital Audio Out." And it's also powered by coffee, apparently. Safety first, kiddos!

  4. The positions of the screws: One in the center (Above the coffee), one above the HDMI port, and that's it. Please tell me if there's a third, I can't remember.

  5. Guess it's too late to heed these warnings.

  6. Pry open the two outer edges of the DVD player. Look to the photos for reference. I removed the top plastic casing to make it easier to access. You can leave it on. (If you want to) I removed the top plastic casing to make it easier to access. You can leave it on. (If you want to)

  7. Would ya look at that compactness? It's "amazing"! (I've seen better laptops than this) Y'all are welcome to scan that QR code. It's probably a repair link or something. Y'all are welcome to scan that QR code. It's probably a repair link or something.

  8. Removing the AC wire. (Could've sworn that this thing shuddered when it lost power) Interesting... They didn't use the center pin. Safety reason? (Or just plain weird?)

  11. Well... that wasn't expected. A heatsink, inside a DVD player? Huh.
    • Well... that wasn't expected. A heatsink, inside a DVD player? Huh.

    • Funnily enough, they provide a preinstalled heatsink for this machine, but not for a Raspberry Pi.

  12. Pry out this little tab, to remove the wireless card. There's no wired antenna (It's on the board), so you can literally yank it out. There are a few silver screws holding down the plastic shield. Remove them, then you can unclip the shield. (Should be pretty obvious) There are a few silver screws holding down the plastic shield.

  15. That's a lot of cabling? How does one know where to find what? That laser assembly looks suspicious. Guess I'll be opening it! It'd be awesome if I loaded up a DVD while this thing was running. Imagine the turbulence from the disc...

    • That grey circle thing is the "manual eject" slot. In case your DVD is stuck and you can't remove it. Although if you remove the top, it's easy to push the tray out. Was this once a PC drive?

  16. I decided to pry off the heatsink for 2 reasons: 1) I want to see what kind of CPU it is. 2) Maybe reuse it for my RPi.

  17. Apparently this ain't an Exynos CPU. I'm disappointed. At least it's MediaTek...

    • CPU: MediaTek MT8553 ARM (32bit, 800MHz Single Core)There's also DDR3 RAM, made by Samsung. (Capacity N/A)

  19. That is one TINY power supply. Like, seriously,  I think it may be smaller than a laptop charger! Yup, it's smaller than my Lenovo's charger box. Wow...

    • There's a pinout for this little IC. Huh.

  20. This weird white goop broke off. I assume it's an epoxy of some kind, but why? This weird white goop broke off. I assume it's an epoxy of some kind, but why?

  22. Here's part of the I/O on the front. The USB port is on the other side.  (USB 2.0 type A)

  23. Why didn't they design it like this? I'm a bit stumped.

  24. All the buttons are front press style, but yet the buttons on the PCB are top press? How does this work? Each button is actually a small lever, so when you press it one way, it pivots slightly to push the actual button.

  25. And with that, the entire Blu-Ray player is dead, never to play a movie again. You don't have to tear it down all the way like I did. The tools shown are an example of what I used, you don't have to be as specific. Every single screw I removed. It's gonna be tough trying to put this back together without duct-tape...
