Left speaker popping sound and right is good

[rockmontejo]

My casio ctk810in had a popping sound in the left speaker... I swapped the right speaker to the left and the left to the right. When i power on, still the left speaker (w/c is from the right) popping. I cant see burn parts in the M708-PSA1A pcb card. The left speaker channel can cause popping... Asking on how to find the trouble.. Thank you.
