If you own a Casio PX-160 piano and are experiencing no sound, you may be wondering what steps to take to fix the issue. In this blog post, we’ll walk you through the process of repairing a PX-160 piano with no sound.
Redeem: The first step in troubleshooting a PX-160 piano with no sound is to check the power source. Make sure that the piano is plugged in and that the outlet is functioning properly. If the power source is fine, move on to the next step. If the power source is working properly, the next step is to check the speakers. Remove the screws from outside body of the piano to access the speakers. Check each speaker individually to see if one or both are not working. If one or more speakers are not working, it may be an issue with the power amplifier board or IC. To check the power amplifier board and IC, you’ll need to locate them within the piano. Once you’ve found them, check to see if the IC is working smoothly and that the voltage readings are correct. If the readings are correct but there’s still no sound, it may be an issue with the transistors. Check the transistors to see if they’re working properly. If you find that they’re not, replace them with new transistors. Once the transistors have been replaced, check the speakers again to see if the problem has been resolved. If you’ve checked all of the above steps and the speakers still aren’t working, it may be time to replace them. Purchase a new speaker and replace the faulty one. Once you’ve replaced the speaker, check the sound again to make sure everything is working properly. If you’re experiencing no sound from your PX-160 piano, it can be a frustrating experience. However, by following the steps outlined above, you can troubleshoot and repair the issue yourself. Remember to check the power source, speakers, power amplifier board and IC, and transistors before considering replacing the speaker. By taking these steps, you can ensure that your piano is functioning properly and producing beautiful music once again.
Redeem:It seems that there was an issue with a burnt carbon line causing it to become completely dry and resulting in no sound. Initially, the solution was to repair all carbon contacts on the PCB. However, upon further investigation, it was discovered that all 4.7V zener diodes had dry soldering, which was causing a lack of signal transmission. Therefore, even though the carbon line was fixed, the connection was still incomplete due to the dry soldering on the zener diode pins. Properly soldering the zener diode pins did resolve the issue of incomplete connection.

We were ready to receive it, but were shocked when he opened his carry bag and revealed that the keyboard was completely burnt and also melted in some places due to overheating. Nevertheless, our technicians tried their best to fix it and were successful in getting it to work properly. The keys were all functioning smoothly and when the client got his keyboard back, he was overjoyed. The keyboard was not just a regular keyboard to him, but also a cherished memory.
