My Yamaha pf 80 is an 88-key electronic piano. It

My Yamaha pf 80 is an 88-key electronic piano. It sometimes unexpectedly turns itself off completely. If I leave the switch on, it may come back on an hour later. Where can I take it in the Cleveland, Ohio area to have it repaired? Or where should I ship it to have a bona fide expert fix it?

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: Yamaha P-200 electric piano does not have any

Plug in your ear phones to see if you can hear the sound that way. If not you are experiencing some internal failure in your integrated amp output.

In that case you will need to get authorised service.

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: how to remove key from yamaha p80 electronic piano

This pertains to the white keys. If you need to take out a black one, you MUST remove the white ones alongside the black one first.

You push the back end of the key forward (takes a little bit of force) and then lift the back a bit to dis-engage it from the back rail. There is a flat spring under the key. Note how it sets in place.

When re-installing make SURE you get the front of the key engaged with the little lever before attempting to push it forward and down to re-engage the back in the rail.

Yamaha pf85 14 keys not working & two of the three circuit boards look damaged.


The PF-85 action works by having the hammers strike the contact strip, which in turn connects the trace patterns on the circuit boards you're looking at together.

Any dirt between the contact strip and the circuit board will cause the keys to not function correctly. You can remove dirt with rubbing alcohol (iso-propanol) and a cotton swab. The only thing on these boards is traces, contacts, and diodes so they are safe to handle...just don't get finger prints on the contacts.

You should also make sure that the white wires are plugged in all the way on the back of these boards. A loose connection will cause the problem you've described. As would missing screws!

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.

Although the keys have a weighted feel, this is not because of a system involving connection t hammers as in an acoustic piano. This is done mechanically, however, which would indicate a need for cleaning. If you have an authorized Yamaha service center in you area they would need to do the cleaning.

Yamaha Electronic Piano- certain notes malfunctioning


Either the first or second closure matrix line for the "A" keys is bad.

This may be a cracked or shorted circuit board.

A bank of diodes is used to prevent sneak electrical path if more than one octave has notes pressed.

First thing is to clean ALL the key contact areas and the conductive rubber pills with 99% isoprophyl alcohol.

This involves dis-assembly of the key area. If you are not competent in electronics, best left to a pro shop.

The keys are scanned in a matrix, two contacts per key and all the individual notes are in common (all the "A;s", "B's"...) And each octave is strobed for the first set of contacts and then for the second set of contacts. an the whole octave is read in parallel.

The reason for two contacts is one closes first and then the other as a key is lowered. The time between these is measured and is the note VELOCITY which for a piano controls the loadness of the note. IF ONE of the two fail, the loudness will vary as yours does.

Some keys damage and piano frezzy up


If you have keys that are stuck down at startup this MAY cause the unit to freeze. The parts are probably availablle to repair the unit. It is likely you will have to take it to a repair facility unless you are experienced at electronics.
