My Tyros 4 Speaker TRS MS404 speaker system is not producing sound in the right monitor speaker. Ive swapped the speakers and cables everything working in the left monitor. Head phone socket is working fine with both channels. Any help greatly appreciated.
Hi musicalmemoriesuk,
the LEFT speaker signal comes out from the Cinch (RCA) jack, labelled with "TO KEYBOARD
L", on the back of the TRS-MS04 Subwoofer.
When you
disconnect this Cinch / RCA plug (or the corresponding 6.3 mm Phone plug on the other side of the cable, directly on the Tyros4), then the LEFT speaker should stop working (for testing purposes only).
The RIGHT speaker signal, however, runs through the Multipin cable. You can only disconnect the 8pin connectors (on the back of the Subwoofer and on the back of the Tyros4), check if possibly a Pin is
bent or
broken and re-connect the Multipin connectors then.
Please check also the short cable that goes to the LEFT Speaker. You can check the
other short cable (from the RIGHT speaker) with the LEFT speaker. If the LEFT is
working then, the other CABLE is defective.
Otherwise, the left SPEAKER could be defective. For testing this, exchange the two speakers against each other. (But leave the short CABLES in place.) If the LEFT speaker is working now, the other SPEAKER is defective.
If this does not solve the problem, you should contact a technician.
Best regards,
Chris
