My speakers just stopped working.

The speakers on my Ellipsis 7 literally just cut out on me mid-song. Have rebooted it multiple times. There is no water damage to this tablet. I can pair my Bluetooth headphones to the tablet and they work fine, so it is the speakers themselves, it seems. Does anyone have a soft fix for this, or am I going to have to open up my device? I love this thing, it's barely ever had a problem and I protect it well, so I don't understand why this is happening.

Hi,

Have you tried using wired headphones to see if there is audio available at the headphone socket to prove whether it is an audio controller, earphone socket or main speaker problem?

Jayeff, sorry for the delay. Wired headphones work just fine, I tried it.

1. Nothing. Not a thing. I used to use it mostly for streaming, but it's a way to play my game faster than on a laptop. I changed nothing. I let it rest for a few days? I mean...I don't know.

2. ...Now that is WEIRD. I was doing what you said, and then...I bumped the tablet just a little with my hand...And now the sound is all gone. Get it fine in the headphones.

3. Nope. Downloaded Puffin myself...It runs Flash, it's the only way to get Flash on Android.

4. Battery seems irrelevant. But I think we have a winner judging from #2...Something must be wrong with the speakers themselves, yes? I should indeed open it up and have a peek?

Hi,

You could try a hard reset to see if this resolves the problem, in case it is corrupted software that is the cause.

Here is a link that shows how to do it.

Before you perform the hard reset, ''backup the tablet using the tablet's backup feature as a hard reset will erase all your data and downloaded apps. It will restore the tablet to its' factory default condition. Also, remove the external SD Card (if any installed) and ensure that the battery is fully charged and that the charger is not connected when performing the hard reset.

https://www.verizonwireless.com/support/...

When the reset is completed, (be patient it takes a little while), test the speakers to see if they now work.

If they still don't work it seems as though you have no option other than to open the tablet and inspect the speakers etc.

Here is a link to the Ifixit repair guide for the speakers in the tablet.

Verizon Ellipsis 7 Speaker Replacement

If they work then restore the tablet using the tablet's restore feature using the backup that you made before.

When it is restored, test the speakers again.

If they still work then the reset has fixed the problem.

If they stop working again, then perhaps a downloaded app is the cause of the problem. The trick is to find out which one. You will have to uninstall each downloaded app, one by one, and test the speakers between each uninstall to see which one is the cause.

Hard reset has not fixed the issue. The thing with the Guide is it only tells me how to take the speakers out, not how to test them after I remove them. I'd like to go further with this but it isn't a complete answer. I also assume I have to figure out where to buy replacement speakers as well--iFixit used to give us these links but that was years ago...(Edit: Have them on order, will have them next week.)

Hi,

To test it you will have to make a 'portable' test speaker.

Find an old small speaker, (from an old desktop pc perhaps or old headphones where you can either cut the cable to access the wires or use an adapter that converts the plug into wires that you can bare,to connect into the motherboard speaker terminals.

Open the tablet and remove the speaker connector from the motherboard. Insert the two wires from your test speaker into the red and black connection points on the board. Play music and hear if it works. If it does try the wires in the black and white terminals and hear if it works. If both work at this point then the speakers are faulty. If neither work then there is a problem on the motherboard.

If the speakers are the problem, here is a link for a replacement part.

Thank you! It will be about a week before I can get back to you and let you know for sure, but here's hoping there's no issue with the motherboard.

Hi,

Forgot to mention it could also be a problem with the earphone socket. When you plug in headphones, there is an internal contact in the headphone socket itself (or sets of contacts depending on which method they use) that disconnects the audio from the main speakers and connects it to the headphone socket.

If it is the one contact method, a signal is sent from the earphone socket to the audio controller that the headphones have been inserted and the 'swap' is electronic. If they use the two contact method when the earphone plug is inserted the 'swap' is mechanical changeover of circuit from main speakers to earphone socket in the earphone socket itself. You will need to view the number of connections that the earphone socket has onto the motherboard and an Ohmmeter to determine what method is used and if the headphone socket is OK or not. If you have to test the socket using an Ohmmeter do it with the battery disconnected from the tablet's motherboard.

jayeff さんによる2017年2月19日

Okay. I am going to take it to a savvy friend's house to be supervised while I actually work on it and make sure I don't brick it or burn down the house. I am sure they have an Ohmmeter.
