Question about Yamaha Full-Size Keyboard
My YPG 625 seems to have the sustain pedal working opposite. When the sustain is pressed it cuts off the sustain and vice-versa. Are there more than one solution to this problem?
I found that if I plug in the sustain pedal BEFORE turning the power on, it works fine. If I plug in the sustain pedal AFTER turning the power on, then it works in the opposite way. Probably just the design. So I would try playing with that before doing anything drastic.

No , there is only one solution, open the pedal and fix it.
Teh sustain pedal has a circuit that can work in two ways:
Sustain from compressor: This will create sustain by using a series of compressor (device that compress the wave and cause the sound to sustain, Black Sabbath's Tony Yommy loved this effect). The compressor is built with a small IC or with a series of capacitors and oscillators.
Sustain from digital effect:
This uses an IC similar to the one used by Digital Delay pedals.
In either case, if the sustain is well connected, and it keeps it cutting the sound, that means that there is an internal fault.
Check first all your cables and connection, with particular attention to the pedal input cable.Also remove batteries from pedal to reset it.
If the pedal keeps cutting the sound, then there is a blown component or a broken solder joint inside, it must be opened , tested and fixed.
Check connections first, and do battery reset.
