CD Player XLR Output channel difference - 1/4 of volume in 1 channel?

[Loekie1]

Hi Guys,

This weekend I've noticed that the XLR output volume of 1 channel was about 1/4 of what it is in the other channel. It all started when I heard a "pop" sound coming from the player. After that the volume difference occurred.
Does anyone have a good idea what the source of this problem might be?
Many thanks and any suggestions are much appreciated.

I expect one side of the driver has gone down. Either the positive or pin 2 or the negative pin 3. Upsetting any balance.

Pop sound ?? output cap / resistor perhaps

Thank you for the tip! Would you mind elaborating on how I can determine if this is the case?

Thank you for the tip! I've checked the capacitors, and they look fine. There was also no smoke or smell when I heard the pop. Could it still be one of these?
