Today we'll discuss a very common problem - the device doesn't charge when connected to the power supply. The reason is probably a broken micro USB port.

ASUS Google Nexus 7 is a really cool tablet. As soon as it was announced, immediately everyone wanted to buy it. But I'm not part of a consumer society, because blood of an engineer flows in my veins ;) and the rush to buy it did not flush upon me. I decided to wait for all the defects to show up.

Six months later, when I got hold of my first Nexus 7, I was pleasantly surprised. The thing had a very high quality assembly (nothing squeaky or loose). A customer brought the tablet to repair the following problem - the device didn't charge. I saw immediately that micro USB port was damaged and after reading the documentation it turned out that I needed to change the DC USB/Power/Audio/Jack Dual Board.

Disassembly

Use guitar pick to open the back cover. Gently press around the cover.

Inside most of the space is taken up by the battery.

The battery must be disconnected in the first place.

Now unscrews the speakers, then remove them.

Unscrew the DC USB/Power/Audio/Jack Dual Board and disconnect it.

And that's how the replacement is done. Now replace with a new board and repeat the procedure in the reverse order.

Conclusion

I really like how this model is designed and not just outside. You can easily replace almost anything in it. May the power supply be with you!

Important notice: do not repair or modify this device if it still has warranty.

I have to do this exact replacement - my micro USB port is damaged. Looks straightforward. But where can you buy the part?

Ted, after I posted my question I found some on ebay but they were $50!
My husband is wondering if he can just solder on a new UBS port onto the board instead of replacing the audio portion too. He can probably take one off an old phone. Worth a try since my son's tablet is useless right now.

The DC USB/Power/Audio/Jack Dual Board can be purchased on ebay, just try to search by
Google Asus Nexus 7 I/O Assembly board audio Headphone jack & USB charger OEM.

About a broken micro USB port, I have never found it as a separate part. So, only possible way is to find a donor (the broken device) where you can unsolder this part.

i'm looking for one myself.
The one that will probably fit is ZX62M-B-5P(02) which is 8mm length body+ 2mm contacts.

No stock on those in NA

If anybody knows one that pin to pin compatible and available in catalog distributors' inventory ... post will be appreciated.

I managed to find just the socket from a seller on Amazon UK.

Its actually better than the original as the metal is stronger and has been joined together better. Took me about 10 minutes to solder and fitted perfectly. Cost about a quarter the cost of the whole board too! Win :)
