Try unplugging and then re-plugging in each speaker one at a time to see whether you can find out whether it may be a speaker, and/or wiring issue. Ensure all connections are secure and if necessary, replace the wiring.

Still having issues: I would recommend seeking service repair, and/or consulting Sony directly for further assistance.
