I bought a second hand first generation nexus 7. Sound from the speakers was working fine, however, one channel of the headphone output was initially broken. To fix this I bought a replacement charger/audio flex and fitted it, and this is where the fun begins.

Headphone out works. The problem is, the speaker audio occasionally drops out, sometimes returning after a while. Having checked the speaker connection, I therorised that perhaps the nexus was thinking that the headphones were plugged in. To confirm this, I installed an app which displays a notification when the headphones are connected. Indeed, when the sound drops out, the tablet thinks the headphones are connected yet they are not. I stuck electrical tape over the edge of the speakers as shown in some youtube videos (the plastic can erode and short out on the case), but this did not fix the issue. I also note that the speaker output is fine if you disconnect the charging/headphone flex.

Having concluded that the replacement flex was broken, I sent it back and ordered a replacement. I put it in and... the same again?!? I can't believe it.

Here is the part I am using:

Is that correct?

Attached is a picture of the original part and the new part side by side. The top one is the original. They are identical in size, but some components differ slightly, e.g. the usb socket and the markings on the flex (e219454 vs. e219454GF).

Anyone know what is going on here? Cheers

For the record, I tried fiddling with the edge connector pins (the ones exposed on the outside of the side of the case) just in case they were not making good contact and shorting something. No joy...

I have the same issue on my 1st gen Nexus 7 after replacing the same I/o assembly. Were you ever able to find a fix?

Thanks in advance
