Question about LG KM900 Arena Cell Phone

2 Answers

My LG's headphone icon stays on even when headphones aren't inserted, I can't hear anything on calls, and no one can hear me. When I insert or remove headphones the phone behaves as though I'd pressed the green call button. I've tried turning it off and back on again, tried removing/switching batteries. What could cause this problem?

Hi the problem is going to be with the part that you plug the head phones into have a good look and make sure nothing is stuck in their as this can cause the problem you are having.

failing that, the chances are the solder holding the socket onto the circuit board has failed and is causing the phone to think the head phones are plugged in, now this could be an easy fix and just need soldering but their is also the chance it could be the firmware on the phone that has got corrupt and is causing the problem you are having.

the problem is their is nothing you can do yourself about this as it will require soldering and getting the phone flashed and the firmware reset, if this is the case and its the firmware then make sure you back everything up as it will be wiped and the phone reset.

now the cheapest place to have this done is one of those smaller independant phone shops the bigger branded ones will send them off and they will then charge you for this service so bare this in mind when taking your phone in for repair.

Im sorry their is no easy fix for your phone but it will either need some solder work doing which will need to be done by machine to prevent over heating to other parts and the firmware can also only be reset and re-flashed at a phone shop, now the smaller phone shops will charge you a lot less compared to the bigger branded phone shops.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

The solution of this problem is plug in and plug out the headphone to your phone several times until it gets normal and then that's it, you will hear again any tones from your Lg phone. Other wise, if this procedure has no effect, then i don't no what to do, just try that procedure.

Speakers not working

Try restoring the ipod or cleaning the ipod jack first. Usually it is caused by the dirt accumulated inside the jack. The ipod thinks there is a headphone inserted even when there is none.

Cd boombox and headphones

HelloWhen a headphone pin is inserted into a headphone socket, it is normal that the internal speaker of the system will cut OFF. It is normal operation, and not a fault. The speakers of such portable sets are wired such that it should cut OFF when headphone pin is inserted into it. We inserts headphone pin to hear the reception or CD music personally. So there is no need for an output from its speakers. Isn't it?

Both speakers on my lg chocolate has stopped working. i can go to my sounds and select play but no sound comes out. during a call i can hear nothing even when i switch it to speaker mode. but when it rings...

I assume you have tried turning the volume up during a call? if so and the volume is all the way up and nothing is coming out, try plugging headphones in to check that there is sound that way. If there is, remove the headphones and that may fix the problem itself as phones can get confused "thinking" there are headphones in when there aren't.

When i insert the head phone in my c5 Nokia mobile, person on the other side can hear me but i am not able to hear anything

Check with another headphone to confirm If the fault stays then it is possible there are problems on the headphone sockets. if not the headphone is defective.
Also if there are same issues with the phone speaker/mic , then it can be related to the circuit. try and open menu - settings and restoring the phone to factory settings.

I cannot hear while making calls. The volume switch does not work either. When I make a call the other person can hear me but I cannot hear anything. The system sounds and ringer volume are turned up....

When making calls, try putting it on speaker phone.
This problem is widespread, and it is due to a problem where the phone does not recognize that the headphone jack has been unplugged. This means that the phone will send data to the headphone jack, and not to the speaker anymore. You can try to 'unstick' it by inserting and removing a jack until it recognizes it, or repeatedly blowing into the phone's headphone port. Both of these solutions have worked for me, but they take quite a bit of effort, so I have just gotten into the habit of using speakerphone. For me it still works, event when the phone is in headphone mode.

I just cooect headphone to VizioP50 HDTV & can't hear anything. is there some step I must do on the remote? Can't seems to find anything about this on the manuel.

You have to check if the headphone is functional and try inserting it 4 times to clear the headphone socket from any obstruction. When the headphone is inserted to the socket there must be no audio output in the speaker of the tv set.
