Tablet Z Right speaker not working

[don320]

I have a Sony "Tablet Z" SGP 311, after I had the screen replaced it came back with one of the speakers not working, (it is possible that the fault started at the same time as the screen got broken). I took it back to the same company, they checked the speakers & the speaker ribbon cable, both of which are not faulty, unfortunately they don't have the ability to check beyond what they have checked already, what would be the most probable cause of my fault.

The system was running Android 4.4 when the fault was first noticed, but is now running 5.01

I have contacted Sony support, but they can't give an idea as to the possible cause or the estimated cost & I have been advised to send it in for repair,  I would like an idea as to what the fault is before sending it to sony.

Hi @don320

I suggest you to first run a backup of the device information like this:

Then try performing a system repair using PC Companion:

I hope can be useful.

I'm at disposal for any question.

Best Regards,
