Dear sylvain
I checked on your website you gave some other way of doing filter rework.
I checked tried to check problem n checked possible shorts. but multi meter shows all part are shorted. also checked each components but it shows that there is direct connection in between all points of baluns.
i would like to try other way for same
Hi.
i would like to try other way for same
I did it several times with a soldering iron. I have twisted a wire around the iron to get a second, much sharper tip. I also sharpend the end of the wire. With a soldering iron tuned like that i soldered the components under a stereo lens basically like normal components. I know this method is a bit extreme but i am not familiar with hot air ;-)
You also should use flux. I have liquid one that sucks itself under the components. Its called FL 88 FLUXI. I am very happy with that.
A multimeter is not the right tool for testing for shorts. It sends a current through the parts. As the parts are soldered into a circuit you can not really distinguish between low impedance components and real shorts and depending on the multimeter quality you might ruin parts. You have no AVR here, its a very sensitive HF circuit, don't forget that. I think you better inspect it visually using a stereo lens.
Don't worry if you ruin some phones, thats normal. I think i ruined two phones before i could do it properly. You also should be familiar with SMD hand-soldering otherwise you won't have a chance.
After the mod do not use the phone for transmitting anymore as you might ruin the receiver then.

hello guys
does anyone know about this The 'hacked up' way with just capswhat value of caps are used in this one ??
