My PSR 620 is behaving strangely. It is unusable because the tone sweeps up or down randomly for the entire keyboard,the same way tones shift when you use the tone wheel. I don't know if this is a component failure, a loose connection, or some integrated circuit keyboard defect. Can anyone help me out? I am electronically inclined and have done minor repairs, such as changing keypads. Dave
