Follow instructions to step 8 (with thanks to Anny for posting it) http://www.annystudio.com/misc/ipaq4700/ With the motherboard removed, you will see the back of the speaker pictured in step 10. I seem to recall that the 'official' replacement loudspeaker (17 UKPounds) looked identical to one taken out of an old Nokia mobile telephone I had lying around. I didn't try it - so I don't know if it would work but the DC resistance across the terminals were about the same. The loudspeaker in the hx4700 is notoriously unreliable and can apparently be damaged by some software titles. I recall that HP published a firmware patch some years ago. I have also found that it is easy to miss the stylus receptical in the top of the device and it is possible to inadvertantly jam the stylus into the earphone socket. This can cause damage to the switch contacts in the jack socket that disconnects the loudspeaker when headphones are used giving the false impression that the loudspeaker itself has failed. I checked this with a multimeter before changing the speaker. In my case the contacts were OK but I doubt that I would have been able to repair the switch contacts without some serious soldering iron weilding. A final note. The ribbon connector for the screen is VERY fragile. Be ultra careful when removing it. Hope it helps. Steve

If the phone does not do so even in the location where there is good signal strength then the trans-receiver section had failed. If you have tools to remove , open and clean the terminals, of the main board, clean the suspected areas of any moisture , dry and set back. This is a highly embedded unit and so the chances of have it done is very little , The option to have it checked,confirmed and estimated is the best way than to tamper with limitations.
It's best to replace your ringer (speaker). After replacing the speaker, you'll know the root of the problem. If it's only with the speaker, there'll be no more problem, but if it's with the ic (small black chip), you'll need to go to a servicing shop to get it checked. As an alternative, you can use your headset for the time being. Good luck.
more than likely the connection inside the phone for the speaker has broken or become loose. I would recommend taking to your cell phone provider and seeing if they have any means of fixing or replacing the phone.
I have the above hair trimmer and batteries no longer hold charge. Take off the trimmer mechanism, that is the two large screws. Then unscrew the screw under plastic button, get flat bladed screwdriver and prise apart the two sections, they just clip together with plastic lugs at ai sides of the case. battery replacement, ehen you open you will see three batteries that have been soldered together. Have not found any easy way of replacing batteries at moment, still working on that one. Good luck Tony B
U must have the right tool 2 open ur o2. Then u can start opening ur o2. Once uve opened up ur o2 u can see the speaker at the top. U can see 2 pin at the speaker, u gently pull the pin upwards but dont pull to hard u might break the pin. When both of the pin is pull up u can close back ur o2 . Then u can test whether theres sound coming out of the speaker. If there is sounds that mean uve succeeded repairing ur o2. Bravo........
i think the firmware files which are needed to detect those formats have got corrupted this may be due to some virus attack ... so try giving restore factory settings .... this will solve your problem ...
check whether you are getting sound like ringtones from the speakers
are not if not then there may be problem with your speaker or there may
be some loose contact in speakers....
hearing the call voice is from the different dont get confused with this ....
to solve problem you must replace the speakers ...
