Yamaha Psr sx700 touchscreen and speaker problems.
I've bought an x700 arranged keyboard, and about a year later, the touchscreen started to glitch, sometimes working and sometimes not.
Regarding my built in speakers, if there was ever a lot of bass or sometimes even on its loudest volume, the speakers would become full of static, even though it wasn't too extreme.
I always treated my piano very well, and nothing that I know of has ever happened to cause any of these issues.
I don't know if people can comment, but if yes, does anyone have suggestions? Please write it yes.
