No service bars

One of the reason why the signal drops is when the phone accidentally fell on the ground,some components like antenna might be dislocated or some parts might got lose contact,but in my case, before opening the phone,i tried to flash or reprogram the phone first using a gsm gadget(i am a cellphone technician that's why i have this tool),and well it is effective somehow.So it means it can be software problem or hardware problem in a way by dismantling the phone and check some parts like antenna and it's interface.



Thank's for visiting FixYa.

reset your cell phone.
then try

It's simple. In order to install the antenna, you must do the following:

Using a very small "star" type screwdriver, remove three screws from the base of the unit. Remove the base trim piece. The body of the phone is in two pieces (front and back). Use a knife to separate the pieces by first GENTLY lifting the locking tabs on the bottom of the unit so that they will easily unsnap by themselves, just lift them a little bit, not all the way. Insert the blade along the side of the seam and pry gently.

Slowly remove the back. There will be adhesive tape at the top piece, so work slowly. Notice the locking tabs on the sides, they will come apart by themselves, no need to worry about it.

After separating the halves, unscrew the top of the original antenna, screw the new antenna in place, slide the back atenna opening over the new antenna and snap into place, making certain that the side tabs insert properly. Just use your eyes and common sense. Do not force anything, but snapping the halves back together will require a firm force.

Replace the bottom trim piece and three screws, you're done!

just go to tools and see what you did wrong if you don't notice anything strange keep it that way it will proble go away.

The older cell phones used to have external antennas, which got much better reception in some cases than the new internal antennas, depending on the brand of phone. There are small sticky internal antennas that you can buy like at wal mart that i have tried and they do improve your signal by a bar some cases more, it is worth a try.

HI

It seems that your fone was not getting any signals from your network.. Try to switch off the unit and remove the battery and resit the sim on the slot, then try to put back all together and turn ON. Also try inserting another SIM if you still don't have signals, if the problems was still there, this can be a a problem on your network or your phone signal was failing and have to be check and repaired.

Hope this info helps

Basically to take any phone or pda apart, unscrew all screws and look for hidden screws under soft objects or labels etc.

ones all screws are out, use a small flat screwdriver or a case opener tool to carefully open the case of the phone or pda. it should snap open, very likely plastic holders on the corners that keep the case closed, carefully snap them open / off, don't break them.

make sure that the antenna is set to on. then turn your phone off & back on. when it turns back on it should say search and then the bars telling you have service will pop up.

Get a T6 screwdriver, remove the battery cover, battery, and sim. Next, gently pop off the antenna cover at the top of the phone exposing 2 of the 4 screws in the back of the phone. The other two screws are already visible near the bottom of the battery compartment.

After the 4 screws are removed, carefully use your fingernail or small flat tool to seperate the back of the phone (D housing) from the keypad housing (C housing). Once this is seperated, you will see the back of the main motherboard. Lift up on the board gently from the bottom. You will notice that at the top, the main cable plugs into the board. GENTLY unplug this cable. Be very careful not to damage the plug or the channel.

Once the cable is free, the board will pretty much fall out of the phone. On the back of the phone (the one with all the heat shields) - you can pop off the heat shields with a small screwdriver or knive CAREFULLY!!!! Remove them all. Look for any signs of corrosion, especially at the top and top right. This should be right above the battery contact terminals. This is where your RF modulator is.

Brush the entire back of the board with 91% rubbing alcohol and a soft to medium bristled toothbrush.

Also, make sure your phone still has an antenna. Sometimes, if this model phone gets dropped, the antenna cover will pop off and the antenna will go flying (just snaps into the back housing). Many people pick up the cover and snap it back on, not realizing they are missing an antenna. To see what the antenna looks like, go to ebay and search for a Nokia 6102i, or 6103 antenna. If your phone does not have this part, order it, snap it in place so that the little metal contact will touch the main board and you're good.

If you do have this part in place, then continue with the alcohol bath. Also, on the front side of the board, you will notice a white sticker which retains all the surface switches of the phone. You can very carefully peal this off exposing all of the contact surfaces for the switches. Make sure this is clean as well.

Dry the phone with a hairdryer. (Rubbing Alcohol evaporates fast, but it lingers longer under the chipsets so it is good to bring the temperature of the board up to speed up the process). A hair dryer won't get it hot enough to do damage.

Once you are sure all the alcohol in the phone is dry, reassemble the phone in reverse order of the way you took it apart.

Let me know what you find out after performing the above steps. If you find severe corrosion, email me. [email protected]

I posted this solution for someone with the same phone with service issues. Follow the same steps to disassemble and clean. The phone has corrosion from the moisture on the backside of the plug on the bottom. This is fooling the phone into thinking that there is a headset plugged in when there is not. Let me know if this helps. And please don't forget to rate. Feel free to contact me via email if you need additional help. Solution #1 posted on Sep 11, 2008
