SOURCE: Yamaha digital piano clp 170

This is a common problem with Yamaha keyboards. The problem is caused by worn-out rubber contacts in the keyboard assembly. In my old Clavinova CLP-500, there was one long rubber contact strip under the keys with two parallel strips of semiconductor material. The Clavinova circuitry determines key velocity by measuring the timing between when the key hits the first and second strips of semiconductor material. The harder you play a key, the less time it takes the key to hit the second semiconductor strip after hitting the first.
After years of playing the keyboard, the keys eventually cause tears in the semiconductor material and this messes up the timing measurement for key velocity. The only solution is to take the keyboard apart and replace the rubber contact strip with a new one.
I got rid of my CLP-500 four or five years ago and got a new CLP-170. The CLP-170 is now having exactly the same problem that the CLP-500 had. Yamaha has re-designed the rubber contacts in the CLP-170 so that there are now eight individual contact strips instead of one long one. The problem is essentially the same, though. You have to take the keyboard apart and replace the worn out rubber contacts.
Here are the part numbers for the rubber contacts that need to be replaced in the CLP-170: V8286600 Rubber Contact, 12 keys, D-C#   Qty. 6 V8286800 Rubber Contact, 11 keys, A-C#   Qty. 1 V8286700 Rubber Contact, 5 keys, D-C   Qty. 1
I suggest you also get a copy of the CLP-170 service manual, part number 001677. It has descriptions of all the steps necessary to take the thing apart and put it back together again. You'll also need a "rod" (which is just a long dowel), part number TX000670. Before you take the circuit boards off the keyboard assembly, you have to insert the dowel between the keys and the frame to keep the keys from falling back and getting in your way. A 5-foot long 1/4-inch dowel will probably work. (I haven't yet taken apart my CLP-170, and I don't have Yamaha's "rod," so I'm not sure if 1/4 inch is the right size or not. I'll report back here if it's not.)
Good luck, Howard

SOURCE: I need a service manual for Roland FP8 piano, or..

Did you ever get hold of an FP-8 service manual? The weight replacement is relatively simple: The case opens by removal of eight screws, four at each end on the underside. The top then hinges up. Keyboard assembly is removed by first unplugging the two white ribbon connectors at the center, then removing the screws at the front edge (underneath) and the screws (gold) at the back of the assembly (accessible from the top). Keys pop out by spreading the two "wings" at the pivot point, and then the weights (Roland calls them "hammers") lift out. Roland will sell you new ones, but I have no idea whether the replacements are any better than the originals. I've done two of these pianos so far, and have a third waiting to be worked on. I do have a service manual, but I think I downloaded it freebee somewhere.
The other failure mode on this piano is the electolytic coupling caps on the output board - I've replaced all of them on both pianos - don't remember the value offhand.

Check if it might be dragging on the edge of the case. The restoring force for some of these comes from a silicone rubber dome that is oart of the contact. SOMETIMES the dome fails.

SOURCE: Digital Piano has sticking key

Typically LOTS of screws... concentrate on those around the edge. USE GREAT care and force nothing when removing the cover...and great care of cables between the cover and the base. Mark the cables so you remember the direction they attach.

When you get edge screws out, then gentle lift and see where it seems to be held...

Some of these synths have 50 to take out to get apart. MOST are in plastic bosses and keep track of the size and length as you can put too long a one in the wrong place and crack the boss.

I use a compartmented plastic tray to keep the screws in order.

We bought this upright piano for our daughter to learn on but I can't seem to find any info on it. Serial number 23930. Any info would be fabulous. Thank you.


Remove the front of the piano. Remove the middle C key complete from it mounting pin. You may find the production date and its full service history written in pencil on the side of that key. A piano tuner told me this after I told him that I had removed all the keys to clean them and I was surprised to see the whole history. It said it was standard practice.

Here is some other information.

How do I fix a stuck piano key on a upright home piano


You'll likely need to try removing the keys, so you can see if something is stuck underneath it. That would be my first move.
In order to do this, follow these steps:

The front panel and the keyboard fall are designed to be easily removed for tuning purposes anyway.

To check it out....The front panel likely has a little clip either side near the top on the inside. Just undo these clips and lift the panel out. The keyboard fall should then be easy to lift out too.

There may be a long wooden rail which you need to take out also. Once inside, the keys themselves can be carefully lifted off the central spikes on which they sit.

Remember how you did this so you can get them back in again.

Since your piano is so old and worn, Often times, the wooden rail in front of the keys (just above your knees when you are playing) bows inwards a little due to age and temperature/humidity fluctuations. This then causes the little white front bit of the keys to jam against the wood and you have to physically lift the keys back up to return them.
If this is the problem you will need to take out the keys and shave some wood off the inside of this rail to allow the keys to move up and down freely again.
Or sometimes you may find you have a small object caught under a key or two. Much simpler to remove and free up your keys, if this is your problem..
Hopefully, this is all you will find wrong with your piano.
If all else fails...
I wouldn't attempt to tune your piano by yourself. I would seek out an experienced piano tuner for that.
But it is worth attempting to repair it first before you go that far.
Good luck !!

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.

Old reply so hopefully it's fixed. Dust or hair can get through the gaps and land on or near the contacts of the electronic key sensors. To be on the safe side (rather than doing a diy) take it in to the technicians. They'll have it fixed in a jiffy

Sustain pedal does not work


Yamaha FC4 and FC5 sustain pedals are normally closed, sorry Fred. Roland is opposite. I suspect the P120 just needs to be reinitialized. Hold down top white key (C) while turning on power. Wait 3 seconds and then release white key. Should now be reset to factory spec. Always plug the pedal in before you turn it on. If it still doesn't work check it with a meter.

Yamaha CP 300 broken headphone jack


Some keyboards use the amp output sockets for headphone use.
You might need some adapters for your headphones.
If it fell in, you would see an empty hole. This would be unlikely because it is held on by two screws. If all fails, buy an amp with a headphone jack input. Plug the keyboard into the amp and use the amps jack.

My yamaha ydp-160 sounds like my pedal is stuck down. All keys are sustaining all notes. Is there an easy fix?


On SOME Yamaha pianos, there is an electrolytic capacitor 1mfd/50v that becomes leaky and causes this. On those with the particular main board the capcitor is at location C94. On other pianos there are other caps that bypass the wire from the pedals that are ceramic. Likely one of these has shorted. There is also a possibility that the pedal contact has shorted. Test for this by unplugging the pedal cable. If it still sustains, then problem is internal. Unless you are adept at electronics this is NOT a DIY repair.
