Check and adjust the sound balance in sound properties will resolve your problem.

Hi.
Ensure that you have already disconnected the unit from power for ten minutes. Ensure that the problem is not the source, or connector to input source, that is common cause of this problem.
Check well the speaker connection. if you have no sound on one channel, then the amp is faulty.
You may have blown the amp final right channel. I do not know if this system uses amps or ICs.
Soldering joints to speaker wiring and components must be tested.
In any case, if the problem is not the speaker or the cable, there is an internal failure, and the unit must be disassembled and tested at component level.
try calling Yamaha at the number listed on the manual and see what cover they can offer for this problem.
Here also a service manual with schematics:
POWERED MULTIMEDIA SPEAKERS
What has probably blown is that upc4570ha in the picture below, taken from page 6 in service manual.
That is a dual low noise amplifier built by Nec. Test for continuity those couple of resistors, eventually replace the capacitor, usually you need to replace the chip if any of them had blown.
For safety reasons all testing and repair must be done by trained personal.
Well, I gave the service manual for free, and the big speaker is called Woofer, not Buffer. If you told us before leaving bad feedback, I could have helped more.
Now that you have received your refund, please change the negative rating given!!
That is only bad for us that have wasted our free time and effort trying to help you.
Goodbye and thanks.

I have checked with more volume and the buffer and the right speaker have very low sound, which is telling me that both are Ok.
Is this new situation gives you more information for a more secure veredict ?
None of the possible solutions is acceptable because you are forgetting that the problem is not just for one unit the problem is for both the right speaker and the buffer. Both have the same problem. ONLY the left speaker works perfect.
The system in the picture above has 3 units 2 speakers and the buffer.
