Defect 3.5mm minijack-connector / how to fix?

[wibroy]

Anyone know how to fix a 3.5mm minijack connector (from a chinese MD3010II).

The jack have newer worked but when I turn a minijack / headphones inside only half the way I hear the sound so I think it can be fixed.. but Im not sure

Is it perhaps possible to change the "chip" that the 3.5mm mount is on? or what is it that make no sound when I put the jack all way in but when I take it only half way and hold it there I can hear sound.. somthing loose connection when I turn it all way in I think.. Can i perhaps twin the cable +- to get sound? Im not an electrician...

Attacted pictures of the chip that connect 3.5mm jack

PS, tryed a mono to stereo jack with no luck also... and several headphones so the problem is the female jack..

Yeah you'll probably need to remove the old jack and solder a new one in there. TV repair place would be able to sort it out for you if its not something you are able to do.

Think I perhaps could replace and solder a new one if I knew what to buy..

Could u help me find a minijack connector or what its called from ebay? that would fit the old one..

Not without seeing it unfortunately. Is it soldered directly to the PCB or is it a panel mount?

Try JayCar Electronics.
Advice could be more effective if we new where in the world you were located.

Likely something like this...

But again, without removing the plug section to look at the solder pads I couldn't say.

Hi!

I removed the plug now and took a cupple of pictures of the solder.. the cables is a bit short so I could not take it compleatly out.. but there is 4 cables connected i see.

one thing..

Can i try to "short-circuit" the solder together with a wire without destroying the unit? to test if I get the "ping" from my headset while I try with the wire around the solder.. or is that risky to destroy the detector?
