Guys, could do with some info here. My dumbarse fool of a brother decided to throw the phone towards me and being such a gay throw it dropped and slid along the floor. Now, the external speaker doesn't work.
Anyone had a similar experience and can shed some light? I'm just about to look for some dissasembly instructions now.
Thanks
Popolou

did you take out 'phone insurance?
I dropped mine yesterday and it bounced down a set of concrete steps. Theres a couple of scratches on the flip, so I guess I got off lightly compared to you. Make sure that you kick the s**t out of your brother!

Kicking the shit out of him is always on the cards.
Anyways, couldn't find a site with the tear down details so went ahead anyway. The thing is in pieces and i think i found the problem.
Will let you know if it springs back to life....

Success!
After taking the thing apart and understanding how it's put together i noticed that the speaker is connected via spring terminals like pretty much the other off-board components such as the vibrator.
Removing the rear cover and battery, there are two small silver torx screws at the top of the compartment. These screws hold the mainboard to the external components tight making the connections via the spring terminals.
I noticed when disassembling that these screws had been worked loose and therefore not creating sufficient compression between the components (in this case, the speaker).
I'll attach some pictures i took (just in case) since this may prove useful to others undertaking the same.

What a pain it was to Bluetooth them from a Nokia N73 to the P990 then save them to a folder whereby i can access them via the USB.....!
Ok, you'll have to excuse a few of the pics; my digital camera wasn't expecting this and nor was i really!
^ The hidden screws that need removing prior to splitting the case.
^ The screws that hold the internal components firmly against the PCB. This is vital for the speaker to operate.
^ Simple shot of the PCB backside. Note the flash (at the top of the pic) was sperated and held back. Be careful as these ribbon cables are very fragile.
^ Close-up of the speaker terminals to the left.
^ Sim holder and connections - the screen connector is the brown one while the white is for the keyboard.
^ Topside of the PCB. Note the vibrator terminals on the left.
^ Screen and keyboard. Note the rubber membrane is still attached.
^ Connections for the screen (brown) and keyboard. Note the camera button in the foreground albeit out of focus.
^ Close-up of the antenna and casing. The case was glued and sealed shut using tabs so was not easy to split open.
^ Another shot of the case. The white seal doesn't show too well unfortunately.
^ The screen/keyboard unit offered up to the PCB. Note the screen and keyboard connections.
^ The rubber membrane is fitted into the trim fascia and sits snugly in place. Note the alignment tabs at the bottom of the fascia piece.
^ The PCB and screen/keyboard units sitting within the front fascia. Note the flash is now in its final resting position.
Well, i hope the pics may come in useful for anyone else undertaking a similar job. I wasn't really expecting for all this to happen tbh, but all's well that ends well i guess

One important note, the small white blobs under the flash support look like thermal conducting foam - don't loose them or the flash will overheat!
Great set of photos though!

Props on the bravery of taking the phone apart and great pics. Is it all back together and functional?

@tsh:
I somehow doubt that, the heat doesn't have anywhere to go... Also, the P990 flash is a LED one. They don't dissipate that much heat.
