Roland HP103 any experience?

[nosaj]

I have s Roland HP103 that on Piano mode pressing the keys kind of moderately makes a overdriven buzzy sound out of the left speaker changing to E-Piano it does not do this (Epiano plays out of the right speaker)

Does anyone have any experience with this keyboard?

Thanks,

I would first verify that the speaker itself is good. Does it have a headphone out or a line out to connect to another amp? If so, see if either of those are also distorted.

I did, I swapped left and right speakers also made sure it wasn't a grill causing the buzziness. Even does it with headphones. Anyone know if Roland is stingy with schematics?

Thanks,
