hey there i`m not an electronics expert but i have some brains. so if someone can help me that would be great.
whenever i play the F key anywhere on the keyboard it gives me an E is this the F card broken or just a bad connection? when i touch the tuning coil in the back the pitch changes.
many thanks

Hi There Beerwolf,
I can think of a few posobilities:
Get a PLASTIC screwdriver and see if you can tune the F oscillator coil up to the F. It may just need tuning.
If you shake the keyboard and the pitch changes,
you might have a cold solder joint in the F oscillator circuit.
Are all the F's the same tone? Or are they divided down the keyboard?
Good Luck
-Karl

Good Luck -Karl all the f`s are the same as the E that is right beside it. and when i use a plastic screwdriver nothing happens. thanks for your response! |

Do you mean that when you turn the tuning pot nothing happens? No pitch change?

Hi Beerwolf,
Well, looks like you are gonna have to open it up.
Turn it off
Unplug it
Open It up to access the electronics.
Don't touch anything with a bare finger just yet.
See if you can find the F oscillator circuit. A lot of the time these are marked on the circuit board with the note letter. Gently push on the parts in that circuit with a pencil (eraser end) Look for loose parts and loose wires connected to that area. If loose - resolder. If you do not find anything like that. Look at the keyboard key contacts and give them a good cleaning. ( check out the keyboard cleaning thread in tech support for details).
If you are still having problems yell back and we will go throught it with a voltmeter.
Best Regards
- Karl
