I'm having trouble being able to select any of my sounds or switch octaves or keys on my Roland RS-50 it seems as if it's stuck.... What do you think I should do

Will probably need to be diassembled and cleaned. Either a sticking key or a compromised contact on the circuit board. Any electronics repair shop should be able to fix this.

How so I fix a stuck piano key

It would depend on why it's sticking. First thing to check is the key bushing felt, then see if the key has swollen and is rubbing the ajascent key. Past that, you'll need a repairman.

How do I get into the keys of my Clavinova 409 - they're sticking

Firstly take a look at the keys that are sticking. Are they leaning slightly to the left? The gap on either side should be equal, you should be able to slide a business card freely into the gap.

If they are leaning to one side it is a sure bet that the key has broken on the fixing under the bank of switches.

You will need to dismantle the keyboard and remove the broken key ( and the bit that has probably broken off ) and replace it.

Replacement keys can be found at www.beckettsmusic.co.uk if required. If you need further assistance contact via the links on the site.

How hard is it to repair a sticking key on the keyboard. I have a new Yamaha MM6 and it's going to cost me all kinds of shipping charges to exchange it. Was wondering if it would be worth it to just...

It kinda depends on if a hammer is broke or key is broke. Or if a foreign object is stuck in there. Typically not hard if you can remove screws and remember how they go back in. TypicAlly the bottom panel comes off keyboards ( start by removing those screws ) or the top case will fold up ( still bottom of keyboard screws ) then multiple screws to realease keyboard assembly. May have to disconnect some wires/ ribbon cables so have a sharpie ready to label to ensure correct reassembly. Then it's all about if they have separate keys or a keytree or sometimes just removing ba key and reseating fixes sticking problems. Get yourself a can of blow off or contact cleaner just in case. Not sure who locally to you sell parts but you can always call manufacturer and ask who does their distribution for parts.

A few of the flat key get stuck on the right hand. On the lower left a few the sound are loud no matter how soft you try a play. Can this be fixed?

I am sure it can be fixed. Who knows what brand or type of instrument this is...

The stuck keys are probably mechanical sticking. The loud keys are probably dirty key contacts that sense velocity.

Take unit in for servicing.

Keys sticking on Yamaha p120 digital piano....how do I open it up

you may not need to open it up.
try using a wax based furniture polish on the keys, it will leave a layer to act as a lubricant between the keys.

Wurlitzer organ, highest key plays note one octave too low.

If this is the kind of organ with the wire sticking out of the key that makes contact with the bus bar to create the note you will have to make sure that key is operating the same as adjacent keys. The busbars have to be clean and the contact wires have to be clean. Sometimes when cleaning the wires they will spring out of place and not make contact with the appropriate bus bars. Check that key against the rest and see what you find. Hope this helps.
