I have a Suzuki HP-97 electronic piano and the keys stick. What should I do to get them unstuck?

Question edited for clarity.
Question moved from Hewlett Packard HP Computers.

Only one place by the look of it.

Have a look at this online manual! https://www.manualslib.com/manual/615241/Suzuki-Digital-Piano.html?page=21

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.

I had an issue with my Suzuki GP-3 and I did a research and found a company called VMI Electronics (619)244-0006 they found me a technician in my area also there is a repair kit called Key Mod that fixes issues with the keys hanging low, here is the link to order it on ebay: http://www.ebay.com/itm/Key-Mod-Piano-Rod-Replacement-Kit-/190822310728?pt=LH_DefaultDomain_0&hash=item2c6de56348

It's very difficult. I advise reading through these instructions all the way to decide if you really want to engage.

First, unplug the piano. Then take the large body lid off the piano. Slide out the 2 pins on which the lid pivots on the left side.

As you start the unscrewing phase, I advise carefully labelling the origin of all the screws (in small dishes perhaps) or it will be very tough to put back together.

Unscrew the ~8 screws holding the fabric cover over the speakers. Two of these screws are triangular head so you'll need a special screw driver. Lift the fabric covered wood inner cover carefully - there's a fabric tab on the left side to give you a start. There are two speakers attached to the underside of the inner cover. Unplug two speaker wires from each speaker by pulling the connection points out and away from the speaker.

Next, take off the keyboard lid. There are 2 screws holding it on each side to the main frame box. Lift it straight up since it rests on 2 wooden pivots.

Release the display panel. There is 1 screw on each side into the frame, and 4 sets of 2 screws along its back edge. Once freed, lift it back carefully and out of the way - there are a lot of wires attached to the display panel and it's best if you don't tamper with any of them. The play in the wires should let you rest it on the main piano box.

Next remove the end blocks beside the keys. There are two screws holding each end block to the floor of the cabinet. Once unscrewed, slide the blocks toward the back about 1 cm to free and lift out of place. The left block has the power wires attached so handle it gently and fold back onto the sound box to get it out of the way without disconnecting it.

Next you must remove the front panel and key box. The front panel faces outward just below (and in front of) the keys. The key box contains the keys, the weighted levers beneath the keys, the contact points and the key electronics - all contained or sitting on a metal box.

There are several steps to remove it. The easiest way may be to leave the front panel attached to the key box - and separate them later.

First, unscrew the ~8 screws holding the back of the key box to the floor of the cabinet. (This will also detach the ground wire.) Then trace the wire ribbon emerging from the back of the key box and detach it from the motherboard - you may need to snip a plastic zip tying the ribbon to other ribbons.

Underneath the piano detach the input jack box on the left side (6 screws) and detach the disk player box on the right side (6 screws). Unfortunately these two boxes block some of the screws you must access.

Next, remove the two rows of ~8 screws along the front underside edge. The first row is ~2 cm from the front edge and the second row is about 5 cm from the edge.

You can now remove the key box and front panel. They should slide forward out of the front of the piano.

You can detach the front panel from the key box by releasing two screws on each side.

Set the key box on a work table. To free the keys, remove one of the plates holding the keys from the back. Each plate holds about 8 keys and has 4 screws to remove. The ones on the ends have less. Next, pry up the black plastic strip anchoring the backs of the keys.

Individual keys may now be removed. To remove a key push it straight backwards from it's normal resting position about 3-4 mm. With a little wiggling, the back of the key should pop out of its restraint. With the back released, slide the front forward and lift it off the key box. A key can also be removed by lifting the front clear of the lip holding it, and then sliding the back portion backwards 3-4 mm - although this requires a lot of wiggling. Use the first method if possible. It may be frustrating to get the first one, but it is possible.

You should be able to see the metal cantilevers beneath the keys. These are what stick. The cantilevers pivot on plastic bushings around two metal axles - the ends of which are visible from the end of the key box (once a small plastic cover on each end is removed - one screw each).

The bushings become worn or swell and stick to each other and their surroundings. You can try blasting them out with air and then adding a few drops of lubricating oil.

When this did not work for me, I toyed briefly with removing the two metal axles, This would allow cleaning all the plastic bushings individually by hand and replacing any defective ones. But there would still be little guarantee that sticking would not reoccur at any time, especially since the instrument is now old/compromised. Furthermore, removing the axles would necessitate taking off all the keys, and all the tiny screws along the top of the plates, and removing all the electronics from the key box.

Removing the axles would mean that to re-insert them each key would have to be threaded, (from the edges in). An enormous task.

I decided to call it quits. I'm now looking for either a new key box I can purchase intact, or another piano, not a Suzuki!!

The contacts probably just need cleaning. Often they are conductive rubber "pills" in silicon domes that the key presses down against a circuit board under the keys. Clean the pills AND the circuit traces they press down on with ONLY 99% isoprophyl alcohol and Qtips. Be gentle in cleaning. Most of the work is accessing the contacts. Note these contacts do NOT for a low resistance contact as the electronics doesn't need a good contact. There are two per key to implement sensing key velocity. Sometimes the contacts are coencentric with a pill inside a ring of conductive rubber. The conductive rubber is always black.

Inspect for damage, especially hairline cracks. Also inspect for contamination or dirt that will change the resonant frequency. AND VERIFY the tuner you are using is accurate. Do not compare to a piano which MAY be out of tune... in fact, pianos are STRETCH tuned, that is the higher notes are SHARPED and the LOW notes are FLATTED deliberately. Comparing your chimes to a piano, the E5 would appear flat. Use a good electronic tuner to verify the pitch, not a piano,

If you have cubic dollars to spend "B?sendorfer" makes a 92 and 97 key piano... These are NOT electronic but are stage Grand Pianos.

It's not really for the faint of heart, but generally this is caused by gunk getting into the key circutry. Underlying the 3000's keyboard is a silicone pad with 2 contacts on it, the measurement between each being hit is the issue usually but yours just sounds like there's something in there causing a physical or contact obstruction.

What you really want to do is to remove the keys and clean everything but this isn't easy... You could try using 99% alcohol (from a pharmacy) to clean inside it which may well help you.

There's a good thread on a similar issue at:

http://www.electronicspoint.com/roland-hp-3000s-digital-piano-dodgy-note-t18946.html

Which may help you work out how to do the disassembly if you are brave, but I would start with pouring some alcohol in and poking it and hoping for the best 1st. It sounds crude, but it works amazingly well with some things.

have you tried using the can of air. you can get it at almost any drug store walmart or kmart. just spray the can of air between the keys and they should become unstuck.
