Hey guys,
Just noticed my bottom speaker grill is uneven. The right portion of the grill looks slightly caved in. I also noticed what looks like white gunk or glue at the bottom of the speaker.
Does anyone have that too? I never pressed it down, I just tried to remove the gunk with a cloth but it doesnt go away. Even with a fingernail.
Soft bristle brush with light back and forth action.
Toothbrush, painter's brush, or anything else similar to that.

Ok everybody, I have taken my PDA2K apart & fixed the wobbly screen problem, First things first:
1. get a sharp knife & carefully slide it under the VOID sticker moving upwards very slowly,& you should be able to remove the sticker in one peice,I have done 7 units ok so far.
2. remove three black screws from the battery compartment,& the silver countersunk screw from underneath the now removed VOID sticker,
Then the 2 countersunk screws from the top sides of the PDA2K,now the rear cover can be removed.
3.Three screws hold down the main PCB,looking from bottom of unit,one screw very top right corner of PCB.One screw Very top left corner of PCB.
& one screw half way down on right side near the ribbon cable for the key board.Then remove the yellow tape over the keyboard ribbon cable,Then lift the black clamp on the ribbon cable connector upwards,and put a round diameter screwdriver under the ribbon cable & pull outwards in a straight direction.
4. Extend the screen fully open & carfully lift the PCB up from the left side (OPPOSITE) the keyboard ribbon cable connector,& hold it slightly up as you carfully slide a blunt flat Knife under the 2 ribbon cables for the display.They will just pop off with minimal force.
5. Pull out the vibration motor & microphone from their casing slots (NOT PCB CONNECTORS) & place the main PCB in a safe place.
6. Looking at the back of the front section you should see 2 screws through slots in the back casing,& 2 at the top rear of the display.remove these & lift the display up from the bottom,carefully guiding the 2 display ribbon cables through the slot.
7. You will now be able to see the sliding plate edges & the two white peices of plastic at the bottom of the slider,These plastic peices need to come off in order to pull the slider plate up further and off the upper casing.what ever you do DO NOT lever the slider plate up with a screwdriver or the brittle moulded painted clamps will snap.if one does its not the end of the world,the slider plate side can be re-adjusted slighty to compensate.
8. With the slider plate in your hand you need to get a flat (NON SERATED) pair of pliers & carefully & very slightly move the edges of the slider plate outwards on each end so they are not going straight up.ie Looking at the plate from the bottom and flat in your hand the plate will look like a U shape,bend the ends out slightly away from each other so they sit against the slider clamps with more resistance,Be carefull not to over do it or you will end up with a very stiff display,
9. Assembly is a reversal of taking apart but be carefull to guide the display ribbons into the top hole of the slider plate,in its open position,
& make sure to tuck the vibrator motor wiring under the PCB before putting the rear casing on.Also hold the volume slider in the middle position as the rear casing is lowered into position.Remember DON'T FORCE ANYTHING or your beloved device will get damaged .
DONT forget to put the yellow tape on the keyboard ribbon cable & the VOID Sticker back on the silver screw & you will still have your warranty.
I have done this mod on a few units with success every time,& this should have been done in the factory,I find it a shame that comparing this unit to the XDA1 its not got the build quality that the XDA1 has and for £580 its a shame that the hardware is not up to the quality of the software features.
Saying that,I can now hold my PDA2K in my hands without its display moving sideways & it makes me feel im now holding a solid peice of kit worthy of £580.
PS I still have 2 brand new XDA1's for sale & one second hand one ive been using for the last year, 07958031182 Thanks & good luck........... :lol:
hi
any1 who has opened the pda2k .. is the camera soldered onto the mother board or is it only plugged in>???
thanks
Hi the camera is only plugged in,but you have to remove the wifi antenna to remove fom the motherboard.hope this helps.............
Not sure how i pulled it off, but my ear-piece speaker (the one used for calls) is blown. My warranty is expired so I am thinking of attempting to replace it. I searched around the forums and didn't find much on the issue except for replacing the external speaker. I did a little searching on google and found this . My question is: has anyone else tried to replace it? Is it very hard?
It is very simple! Pull the back off the phone, then pull the battery. Pull the 4 screws on the corners, lift a corner of the red back and release the black tabs as you apply pressure then the red back will pop off.
Then pull the yellow stickers off the connectors and release them by lifting the black tabs and pull the wires out. Pull the two silver screws on the top and bottom and then lift the motherboard out and the speaker will be right there on top. Pry it out with a little screwdriver and replace. It really is very simple.
There are plenty of videos on the internet. Just google it.
Hi,
Past few days at high volumes the top speaker voice is shattering. I removed the top grill and cleaned.Even after cleaning the problem persist. So i tried removing the black dust cover over the speaker and speakers were working perfect .
It seems the paste the culprit is the lose black dust cover over speakers.Any idea how I can stick it back properly or which adhesive to use
thanks

Are you sure there's not small metal fragments in that black screen? Metal fragments will do that.
Good morning;
So, my Nexus 7 took a swim. Fortunately it was a quick one and I was able to recover it quickly and it found it's way into a nice dry rice bath following.
There it sat for a few days until it was nice and dry. Power it on and blammo -- tries to boot into recovery or safe mode.
Fast forward to my best understand of what is happening -- it thinks the volume rocker is being pressed 100% of the time.
So, anyone have any thoughts or suggestions on what I may be able to do? I guess I'll have to buy some sort of replacement part -- but presumably it's not a modular component I can simply replace.
Think I can just 'remove' the volume control entirely?

Just to be clear we're not talking about the plastic buttons protruding on the side of the tablet. Inside, barring some short on the circuit itself or fried components(this you can do by inspecting points of contact on the ribbon, the inside of the connector and the soldering traces at its end), the amber ribbon consisting of power, volume and microphone can be removed from the bezel by very slowly scraping the double-sided white tape underneath it from one end to the other (if you use a thin blade, make sure you insert it between the tape and the bezel and not between the tape and the ribbon itself).
Once out, you will notice that contact is made when the thin round metal plates are pressed together. There are 2 layers. If you again carefully peel off the upper layer (transparent mylar or film), you can see if anything is stuck in between (water or vapor), or that one plate is depressed permanently that it would make contact all the time.
The rest is just a matter of pushing it back to the normal position and realign both layers. Usually, there would be enough adhesive left for them to stick together without your having to add more.

Thank you for the reply.
Yes, the rocker buttons do continue to rock like a charm. I'll have to crack it open and have a look. Thank you for your advice.
Hey,
Got some dirt inside top speaker grill, any ideas how to clean it? The holes are too small to use a toothpick or needle
Compressed air.
I thought about that, but this could damage membrane inside, don't really want to destroy speaker.
I have used the canned compressed air. I'm just careful to not point it directly into the grill, but instead I do it at a 45 degree angle and not too close to the grill surface.
did it work? no changes in sound later?
Maybe try a little cleaning slime?
Before it gets really dirty
By rubbing with fiber clothes,
Adsorbed by static electricity, it will be somewhat clean

It works to my satisfaction. I use a soft bristle toothbrush to lightly dislodge any large grime and then run the compressed air at a 45 degree angle. The typical dirt that mine picks up is from placing it in my pocket - so lint and such.
Cleaning slime actually worked. Thanks to all.
I did it too! Thank you so much for the advices!
