No sound will come out from the internal speakers

Hi, I’m having problems with my Toshiba Satellite A50. No sound will come out from the internal speaker. But when I use the headset, I can hear a sound. I’ve checked everything and everything is set to play sounds, just not with the speakers alone.
I want to disassemble this speaker and see if there some dust or whatever, how can I do that?

If you want to replace speakers on Toshiba Satellite A50 notebook, you have to remove the top cover assembly. I haven’t created a complete laptop disassembly guide for this model yet.

I think that cleaning up the speakers will not help a lot. If you can hear the sound from the headset but not from speakers, then I would suspect that the speakers are bad, the speakers are unplugged or some sound circuit on the system board is damaged. Try to reconnect the speakers first. The speakers are connected directly to the system board through 2 little connectors located below the keyboard connector. You can see these connectors on the step 6; they are hidden under the white tape.
