Hi, thank you for reply. Yes, it always covered when not in use. Basically it is used everyday for around 2 hours. So, it was working well, and next day stopped. I have a short video how it works now, which i sent to some technicians but they don't know what is going on))). I didn't try compressor so far.

Hello everyone, I need help with Casio PX 735. It worked perfectly since 2012, but suddenly something went wrong. It starts normally, the Function keys work well, Demo songs play right, but some of piano keys don't do any sound, and some produce randomly loud, quite regardless the pressure. So shortly saying more than half of keys are silent, and very few do sound. Please, let me know if you know solution. I would like to see experts opinion before bringing it to workshop. Thank you
