Hey,

I´ve got a problem when tryin to solder in my battery dock connector.

i´tryed to bridge one of the missing connectors to the upper little (resistor) under the metal shiel. While doing this I unfortunatly burn of one of the resistor so there is just to metal connectors left where the connector was sitting.

Is the the telefone damaged or is it anyway to fix this?

Regards,

/ Komeda

Answered! View the answer I have this problem too

Is this a good question?

Could be plenty of SMD components, ie. Resistors, Capacitors, Inductors and plenty more. Unless we see the location of the burned/missing part in relation to the logic board, anything is a guess.

Chosen Solution

Komeda, just tried to make out what you are looking for, but the images are not really giving enough information. this is not an answer to your question, but I am trying to show how to import images into your question. First you got to select "edit" on your original question

Block Image

You should see an orange tab on the bottom left that says "Images"

Block Image

Click on the tab and a small window will open up on the bottom of your screen

Block Image

Now click on the blue "browse files" you should now get another window

Block Image

that shows you the directories. here you select the directory where you keep your images

Block Image

select the images to import and click on "open. the image should now show in the smaller bottom window. Left click and hold the images, drag it into your edit window, the one where you typed your question. This should enable us to see your images and to help you with your problem

Update

Komeda, looks like you are inquiring about the component pointed out by the yellow arrow:

Block Image

that would be the filter FL7_RF 240-OHM-0.2A-0.8-OHM

Block Image

As a replacement, you could use this filter MMZ0603S241C available at Digikey.com part number 445-2144-2-ND

This is of course a SMD component that is 0.6mmX0.3mmX0.3mm in size. One better have the right tools and the right knowledge to replace it. :-) You may get away with using a circuit writer pen and bridging this, but it is the gauge gauge, it may give a bit of trouble with that. Hope this helps, good luck.

2nd UPDATE

Komeda, hope this images will describe it better.

Block Image

No. 1 is FL7_RF 240-OHM-0.2A-0.8-OHM

No. 2 is C20_RF 100PF 5% 25V CERM 201

No. 3 is C12_RF 100PF 5% 25V CERM 201

No. 4 is FL5_RF 240-OHM-0.2A-0.8-OHM

No 2. is also part of the Gas Gauge

No 3. and 4. are part of the NTC connection. NTC circuit is usually related to the thermistor for the temperature sensing, essential the batteries feedback. So anything related to that circuit could essentially be reason for your battery to i.e. overheat or not sensed at all. If you are going through the trouble of replacing, which I would suggest, I'd replace the parts properly. This way there will be no second guessing and you know that it is fixed. It is most certainly difficult and will require the right tools and practice, but it can be done. This is one of those cases where the hiring of someone with the tools and experience may be beneficial. Again, hope this helps, good luck.

Hey,

Thank´s, had I known this i think i mangede to solv ethe the problem but the problem now is that the connector are damged were the filter three and four were sitting. Is it any possible way to get the phone working without it?

by

Komeda, you are referring to filter three and four, by those you mean counting down from the one you shown on your image?

by

Sorry the opposite side I mean, from the picture with the arrow I mean the filter one and two.

by

Sorry I am not exactly sure which component you are referring to :-) may be you can post an image :-)

by

Ahh ok, in your image the yellow arrow shows the component one, and the other nr. two below (of four) are also damaged.

http://guide-images.ifixit.net/igi/mo6DY..., here is a picture that you can maybe point things out a little clearer, I'm understanding you caused some damage soldering, you may be able to use this circuit writer pen to bridge something instead of soldering, it does work well, http://www.amazon.com/CircuitWriterTM-Pr..., good luck, If this answer was helpful please remember to mark it accepted

Hi,

Thanks for your reply,

Is there anyway to attach pictures in the thread? My problem is this one that I´ve tried to bridge.

http://www.google.se/imgres?hl=sv&client...

This scheme in Piont B views the restor that I´ve damaged.

Anyone know any solution to fix it?

by

Its real hard to look at the picture in your google link and give any advise, if you can get a picture of your phone it would be real helpful.

by

The link describes the way to bridge a missing connector. The problem is when I solderd in the bridge the Point B resistor was damaged but under it the two anchor point for the resistor is still there.

I don´t know how to upload a picture?

by

Here´sone more link that shows the solder bridge. The little yellow dots is what I´m talking about
