Cant hear when others call neither i can hear when i call but they can hear


Hello,the problem you are experiencing could be caused by two things,
1.Bad ear piece:this could be fixed by replacing the bad ear piece,you can get it fixed either by getting the ear piece parts from any phone accessories stores and fix it your self,or you visit a mobile phone engineer to fix it for you and your phone would work perfectly.
2.ear piece volume low:this could be fixed by dialling a number on your phone screen,then tap on the botton on the right side of your phone,ensure you tap the upper arrow to your desired volume level.
wish you good luck,
take care.

Will not work with turtle beach x11 head set no mic...


take your cell phone ear piece and mic attached cable and clamp the mic part with the clamp that is on the cable to the end of the turtle beach mic piece just before the foam cover with the cell phone mike facting toward you. plug in the cell phone ear piece to your left ear and then put the tuttle beach head set on just a normal. the cell pone ear piece is so small that you will not even know it is there when you cover it with the turtle beach head set. plug in the cable from the cell phone into the port in the rear of your turbo fire two controler and away you go. you can enjoy the great sound of the turtle beach head set and at the same time chat with the cell phone mike. you can adjust the sound level on the head set but you will not be able to adjust the volume on the cell phone mike. but it works fine just place the head set mike boom real close to your mount so your friends can hear you well. I use it in two worlds two in the marshlands while leveling up on x box live. you can find me a DeepReserve which is my game tag.

best,

EAR PIECE REPLACEMENT


How to check and correct a bad Ear Piece

Equipments Needed
Digital and Analog Meter

Procedures to Follow
Step 1: Check and read your ear piece to see if it's good
Step 2: Check if the terminal is connected on the board interface.
Step 3: If it is not connected, clean well and make it connect.
Step 4: Read the board interface to see if it is reading continually, if it isn't, loop for sound.
Step 5: If it's a flip up phone and the phone interface is not reading, you have to replace the flex to obtain sound.

Left earphone keeps dying out and comes back. Also the red light on the mic keeps coming on which blocks me from talking online.

I fixed mine by removing the soft ear cup then the two screws under this cup then carefully pry that top piece off the next lower piece. It will come but it is stuck with some soft glue.
Next, unsolder the two wires on the back of the speaker taking note of the polarity. These wires are what are broken. Undo the screw in the center. With a small screwdriver carefully pry the pivoting cup off the ear piece. It is snapped onto a small ball joint under the screw.
Now remove the four screws and remove the top of the ear piece.
Remove the two screws from the small printed circuit board and unsolder the two speaker wires. You will need to find some new wire that is flexible and not much bigger in diameter. I used some that was too large and had trouble getting the last cap that holds the soft ear cup back on. I also reamed out the holes in the cap and the cup that the wires go through to give them more movement.
Replace everything and solder the wires to the speaker in the same order as removing.
You will need a good small tipped soldering iron.

Good luck

I have an older triple head Tycos Stethoscope that has a metal spring-like bridge at the bas of the ear tubes, and which holds the ear tubes separate. This broke near the connection with one of the ear...


If it's less than ten years old, it may be under warrantee. When mine broke, 15 years ago, I had to replace the whole Binaural/Spring Assembly piece- the metal ear tubes and the spring are all one piece.
Major med equip suppliers- Schein, Darby, etc., stock the parts. WA has them, probably for sl more-plus $10 extra charge for orders under $100.
I found them here:

I have a set with one ear piece working


I don't have one, but are you sure the ear piece itself is bad? Usually, the problem is in the plug, cord, or termination at the ear piece. Troubleshoot with an ohmmeter (pocket DMM has one) and repair with a soldering iron.

No call volume om samsung e250


This because in your handset there will be 2 speakers
1 is loud speaker and 2 nd one is ear piece speaker....

so the loud speaker is working fine ...
There may be some loose contact in the ear piece speaker or the speaker might have got damaged ...

so if you are good at opening then just open your handset and check if there is any loose contact in the ear piece speaker .. is so fit it correctly ..
or you replace the ear piece speaker with the new one ...

if you are not good at opening then just contact the technician ...
he will do it ...
The ear piece speaker is very cheap so no problem .. just buy the ear piece speaker which is compatible to your handset in the shop if you are doing it by your self ...

the technician might take the service charge for this that s all but the ear piece speaker is too much cheap ..

any doubts reply me
i am always here to assist you
thank you
bye ...

Nothing on screen


ltd1991 - take the phone to either a mobile tech or mobile service center close to you and have them replaced either you flexcable or LCD screen.

mk_rodgers74 - you need to have the ear-piece replaced but you will also have to get the lcd change at the same time seeing that the lcd and ear-piece are both connected to the board or they meaning the mobile tech or mobile service center could unsolder the old ear-piece and resolder the new one back to the lcd board.
