Re: Yamaha Electric Piano CLP550 no keyboard output
If, as it appears, your ROMs have rotted over time, then there is hardly any point trying to pull them and read the codes. That's what I did; sent them off to an enthusiast in the UK who read them and confirmed they were corrupt. Unless someone manages to get a good read of all three ROMs you (and anyone else with the same issue) have no chance to get things going again. With the correct ROM code it is simply a matter of burning to compatible EPROMs. But we need the good code first.
Sorry my friend, but you have gone up the same dry gulch as many before.
