Roland FR3s speaker issue

[kimric]

I have a Roland FR3s in my shop and the onboard speakers stopped working. I went through the manual and can't find anything about turning the speakers on or off other than plugging in something like a headphone jack. Trying to figure out if someone pushed the wrong series of buttons and somehow turned them off. The FR3X does have a speaker on/off function.

Hello,
A possibility would be that the Midi In/Out setting is changed to "Midi In" (see page 48 of the english User Manual).
in this case, you would not be able to play a note from the FR3s keyboard, and would get a "---" display ....

(assuming of course the output still works through an external amp)

the dummy plug into the headphone jack is a hack
that was commonly used to mute the internal speakers,
yes, and it works because of the complex wiring scheme of
the 3 output jacks on the bottom of the grille..

in other words the output signal is routed around according to
the positions of internal switches built into the jacks

occasionally, when a plug is pulled back out an internal
switch" may not make good contact as the steel flexible arm
springs back into resting position.. whether due to fatigue
of the springiness, or contact point oxidation, the normal
signal flow for the internal speakers is THROUGH the headphone
jack wiring/switch

occasionally, firmly and repeatedly plugging into
the headphone jack "cleans" the contact point up
and it will again make good contact at rest

the wiring also relies on switches in the left/right
jacks as well, it routes stereo or monio, so it is also
possible a weak contact point in either of those
can also be the problem, so work them a bit too
flipping the grill open can give access to the jacks
to follow the wiring and "jump" the switch or
replace it if necessary

i have never seen or even heard of an FR3 amp section failing
so i cannot offer anything about testing further

ciao

I was thinking along the line of a jack causing the issue, since it works with an amp plugged in. I was not sure if it switched off the speakers mechanically or electronically. It makes sense if the switch was mechanical that there would not be a menu option to turn them off. Thanks.
