I have a PA800 that has distorded sound from styles and tones , I already reset the OS.
when I put something from audio input it comes out of speakers clear but if I play anything from the keyboard itself it sound cracking with some background noise and distortion kind of sound.

I was told its the sound board but if its the sound board its should have issue with playing something from input as well.

if anyone has any suggestion plz let me know.
Thanks

Well i don't like it but its the CPU board causing the problem.
The ram part gone faulty.The reason you hear the mic/line input ok its because it never reaches the sampled ram chips..It is played back directly after processing...
IF only ram sounds are distorted, then it may only be the ram module.If factory sounds are distorted too, you need to find a working cpu board or get yours fixed if possible.
