I have a Roland HP 2900G, no sound from the keys, no sound from headphone jacks. I have power to the circuit board that has 4 fuses, all are good.
I cleaned the volume slider with contact spray.
If I take the fuse out next to where the power comes in , and use my tester it has power, it seems the other 3 fuses arent getting power at all.
Also the circuit board that has the vol and brilliance knobs also has some issues. some of the buttons are broken, however the little switches underneath appear to light up.
Im wondering if just changing that board that houses those switches might help?
Also I plugged an electric guitar into the back of the unit, and it works properly, altho the volume on the keyboard did not change the vol on the guitat, only the vol on the guitar did.
Any help would be much appreciated.
THanks in advance
