I bought a SX-1500TD and the owner said that it it powered up but no sound. Got it home and played it for a while to check it out, with speaker wires stuck in the speaker jacks. I got the left speaker to work but no sound from right speaker. So I did a total deoxit and gold treatment hoping that's all it needs. Finished up and still no sound from right speaker, and no sound at all from headset. Could you help in guiding me in the right direction to start troubleshooting the problem with the right speaker and the headset not working. Eventually I want to do and entire recap, after I get the problems fixed. Here are some pictures.
