Casio PX-135 help needed

[basic_user]

Hi.

I have a 10 years old Casio PX-135. I have some issues with distorted sound coming from build in speakers and headphones. In debug/diagnostic mode the sound seems to be ok.
I think I need to re-flash the ROM with the original sounds. Where can I find rom files and a flashing utility for my piano? I don’t have anymore the original CD.

Thanks!

Not helpful. I checked their support page, downloads, etc. and nothing useful yet.
google.com is also covered, btw.

I think Casio does most of its support through facebook these days.
