Default Disassembly Guide: Samsung P3

This will cover taking apart a Samsung P3, model used is a Samsung P3 32GB Black from BH Photo Video.

Tools used:
Electronics screw driver set

This guide should only be used if you do not care about the product warranty or your device's warranty has elapsed. Onto the guide then.














The screw cover is between the power/hold and the minus volume button. you can use a flat head screwdriver from the electronics screw

driver set. Or you can pick at it with a fingernail. You can pick at it from the screen side and it will come out.

Once the cover is out, it will show the only screw. It is a VERY short screw which can be lost if your not careful.




Once the screw is out, place the P3 screen down. Push and slide the metal backing in the direction of the buttons. It will look like

this:




Once you take the back cover off you can see the insides.







At this point, you can seperate the PCB by disconnecting the 2 connectors and use the screw driver to remove the 2 screws. Angle the

board and slide it out slowly. The LCD screen molex is attached to the underside, once disconnected you can flip the board over.







The battery is connected by the underside. You will need a small spatula to remove the battery from the metal frame.

To disconnect the LCD, you will need to disconnect the metal frame from from the chrome plastic. There are 5 screws on each side.







There is 1 screw that will be very difficult to remove, it will be located on the left side. The screw is partially covered by the

rumble/speaker assembly. You can shave some of the black plastic to get at the screw or you will need to seperate the assembly with a

small spatula.

Once all the screws are removed, you can detach the LCD from the chome plastic. At that point you can clean the LCD.

I didn't get around to removing the last screw. So there isn't any pictures of the LCD and inside of the glass touch screen.

It is relatively a short guide. This ends the guide.


Notes:

Nand ID guide to identify the Nands used:
http://www.samsung.com/global/busine...Nand_Flash.pdf

The 8GB and 16GB use single NAND modules located on the underside of the PCB.

The board is by assumption, that it is capable of 2 32GB NAND modules with a total 64GB possible.

The boards are also dated with the production date. The board in this P3 has a date of 2008.10.06.



CPU identified:
Telechips TCC7901 : click here

DRAM identified:
EOREX EM48AM3284LBA-75F : click here

NAND identified:
K9PDG08U5M-LCB0 (There are 2 16GB NAND in the 32GB P3) : click here

Bluetooth and FM identified:
BCM2048 : click here

Unidentified chips:
8819AE TI920 NTAE
WM1800G 8BCDPLS (most likely the sound processor, visible wave pattern printed on top of chip)

Battery identified:
610mAh 3.7V Polymer Lithium Ion battery : click here
(There is no visible power circuit attached to the battery)

The glass screen's senors can be seen as dots and 4 rows of diagonal lines connecting them.
From what I can see there are 6 columns and 10 rows


Thanks goes to logik for finding the where the screw was hidden.

The only difficult parts of it is the 1 screw and reconnecting the LCD molex to the back of the board. The ribbon cable is short enough to make it slightly difficult, other than that it is pretty straight forward taking it apart and puting it back together.

All the screws are short, a magnitized tip would be a preferred.

The WM1800G chip search only came up with suppliers and no data on it. Wolfson didn't list it when I checked either.

maybe Samsung made their own sound chip for their fancy DNSe 3.0... just an idea...

anyway, nice work! I always wondered what that "blank button" was for

edit: btw, I look at wolfson's numbering system, and I noticed that all of their products start with WM, as does the chip name in the P3....

Wow, the p3 has a weaker battery than my p2. My p2's battery is at 1200mAh or something near that.

If they removed the speaker/rumble assembly and put in the smaller rumble unit, the battery space would be much bigger. I could live without a speaker.

I wonder how long it takes a mod to sticky this one.

On a side note, I found out some interesting things about the emodio software which I will post in the subsection in a few more days once I finish documenting it.

Perhaps Moderators have a lot to do, maybe they use their free time for testing mp3 players for the Samsung community, maybe they don't have time to read every single post and thread on a forum, maybe english is not their mother tongue and it may be an effort to read long posts in english, maybe you should let moderators do their job.
If you knew all what I do and already did for the Samsung Community, you would understand why it takes long to stick your thread...And as far as I know, I have the choice to stick it or not....Thank you.

That is ironical, isn't it?
You did a good job, your tutorial is good. But the way you asked a moderator to stick it is really unbelievable.
I'm currently reviewing the R1 for gmp3 and it takes me several hours and days. Please take that in consideration. Don't be egocentric. Everybody is trying to do his best here. And I hadn't seen your thread before.
Now it is sticked. That's it.

If you got one of those radio shack screw driver sets, use the No.0 to get at the screw.

Picture below if you need to know what type of screw driver set I am refering to.

So Samsung potentially could have included a camera and TV-out? (from the Telechips page)
Too bad they didn't... Maybe a camera wouldn't work with the OS backend?

Default Memory Upgrade

How is the second nand soldered on the pcb? Is it possible to double the memory by putting the second nand upon the other? Or is it possible to replace the nand from 8GB to 16GB or from 32GB to 64GB?

Edit: Oh, i see, the first is on one side, the second is on the other side of the PCB. Which ones missing when there is only one nand? Do you think it is possible to upgrade the memory manually?

Nope, the P2's battery is quite a bit larger (squarer) and will not fit the longer skinnier P3 compartment.

If you are having battery issues just buy a new one off ebay, they're only 15 bucks or so.
