basic_user Posted May 21, 2023 Share Posted May 21, 2023 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! Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted May 23, 2023 Share Posted May 23, 2023 It is not possible to do that. What does it sound like? Quote Link to comment Share on other sites More sharing options...

Brad Saucier Posted May 28, 2023 Share Posted May 28, 2023 Unfortunately the only solution I'm aware of is replacement of the main board. Quote Link to comment Share on other sites More sharing options...
basic_user Posted May 29, 2023 Author Share Posted May 29, 2023 Do you know if I buy a ‘MDA1 PCB ASSY/MAIN’, it will come flashed with the right FW? Can I ask on this forum for a link where I can buy such part? Also I see that px130 and px135 have same build. Anyone knows if there is any difference between the main boards?
