Check something, will you? Is the RH side audio also gone from the audio outs and the headphone out? Or is it speakers only..?

If speakers only, it might be something as simple as a wire gone bad, possibly fixable yourself. If ALL audio is gone no matter the output, that might be more cause for concern.

Thanks for the reply`s,the headphone and stereo audio out jacks are also just one channel,I don`t think I`m competent enough
to try the tests that loshk has provided but perhaps they look more complicated to me than they really are.

See "Left" and "Right SPEAKERS" at the top of this picture.
Follow the pattern lines from the speaker to the audio-amplifier (bottom left)
Could be faulty contacts W27 or W28
Could be faulty contacts CN3 or CN5 on the board "BI-power AMP"
(See larger Scheme of Board for Roland E-80 at this link www.roland-arranger.com/index.php/files/miscellaneous-files)

1. Can be in the mixer shifted left panorama (L 63)?
2. If you play a MIDI file, you also have no sound?

(Sorry Terry, I missed the earlier post where you said that)

I think that probably the main thing you could do for yourself, if comfortable opening up the E80, is to re-seat all the ribbon connectors going to the main motherboard, and those going to the output boards. As long as the E80 isn't powered on, you can't really do any damage as long as you are careful disconnecting them and reconnecting them.

You can also do a visual inspection if the E80 is opened, and see if there are any areas that look corroded (perhaps a little water or drink might have dripped inside or condensation) especially around the ribbons and output boards.

We have had stories of people having a few issues that, after re-seating the ribbons, went away (I remember someone with a faulty display that corrected itself after re-seating the ribbons to it). Anything much more than that, I'd leave it to a certified Roland Tech. Including, TBH, doing the diagnostics Loshk posted. After all, if you don't feel comfortable messing with the insides, not really any point doing a diagnostic check that the tech is going to do anyway!

But there is one thing that IS critical at this point... Make sure you have a COMPLETE backup of both the Internal drive and the Card (if you use one). Usually, any diagnostic checks and work on the arranger will possibly wipe the memory (if he's thorough, he'll probably reinstall the OS), so you want to make triply sure that ALL your work is backed up.

I had this same problem it cost me around £80 I can recommend an engineer if you require assistance.
It's a part the controls the sound on the keyboard.
Did you notice a crackling sound when you turn the volume or anything up? because that is a sign of this problem.

Thanks for the reply,when I first had this problem I had it looked at by an engineer who could find nothing wrong but he said it could be
an intermittent fault.It worked perfectly for two days when I got it back but then the fault appeared again.Unfortunately the engineer is on
holiday so I will let him have a look again when he`s back.

hello musicians and friends,
It seems that I've got the same problem concerning a faulty sound output of my E80.
No more sound on both channels (speakers, line and headphone)
I wonder if it will be possible to get a service manual and/or schematics of this keyboard.
I made a lot of search with no result, and before I open it, I prefer to have a schematic in order to understand the analog treatment and way of the sound.
regards

Make sure that the speaker off switch under bottom right of keyboard is ON (no red light).
If this is ok, look up the post from loshk on December 25th 2014,this will give you the schematics.
I`m not sure how to direct you to it.

If no more sound at the same time on both channels (speakers 1, line 3 and headphone 2), i.e. in three areas 1, 2 and 3 (see. below the red numbers 1, 2 and 3), the common point to supply a sound Master volume control (shown red arrow). Perhaps from the shuddering disconnected socket (wires from the contact) of the Master volume control..
