Since they are wireless I don't think there is a way you can know that the speakers are OK since you can't use them without the wireless transmitter and receiver that they need.
If the rear speakers can be paired to the side transmitter then you could find out if that transmitter is the problem or the side speakers or the wireless receiver built into them.
