    Yes that is the fault on my Yamaha CPL130 and I agree it is likely to be digital. What is my next step to fix the problem?
    thanks

I think you must also ensure that there are not varies at AC line to power supply.
Utilize power outlets that are on different branch (circuit breaker or fuse) circuits or install AC line filter/s.

Intermittent failure of some of the keys could only mean that you need to clean the keyboard from within. another possible remedy for this is to have it serviced as there may be faulty chips.

Yamaha CLP-130 Clavinova right?

since this is an electric piano, it is prown to electrical surges.

Well..that is caused by one of three things

a. the sound board(really a digital one) could have some glitches on those keys.

b. the tone recognition firmware, which looks for particular 'keys' may need to be revised and updated

c. is it the case that all 'C' and F# are bad, then it's most likely digital and not mechanical..

please confirm actual failure mode..

Casio px-330bk keys pitch sharp top half of keyboard


The problem you're encountering is actually a feature, called stretch tuning. While real pianos are tuned in this way it's meant to sympathise with their natural 'organics' and might sound wrong on a digital instrument. The solution is to turn stretch tuning off. The manual should be able to tell you how.

I just experienced my p85 with a key problem on the F# below middle C. You will need to disassemble the keyboard and usually the keys are groups of 6 - 8 keys. If you remove the group that has the problem you might be able to find the problem visually. Mine just involved removing and reinserting the F# key back into the assembly. Then reinstalling the group of keys. If you can't get the key to work properly, you will probably need to buy the group assembly from Yamaha.

Need to be tuned.


Unless there is damage you should only have to clean them. Do NOT compare pitch to piano since on a piano the high notes are stretched up to 22 cents sharp and at the low end they are about 20 centts flat. If any of the tubes are cracked, it is fatal. Also do not be confused by worn or deteriorated hammers that may appear to be out of tune.

This is a problem with one of the two contacts for that key. The contacts close at different times as the key is depressed and the time it takes between is measured as velocity which is used to control the loudness as in a regular piano. The contacts are conductive rubber pills. After a lot of dis-assembly you can clean them with 99% isoprphyl alcohol and Q Tips. Clean both the pills and the circuit traces on the board they are pressed against. Be very careful of the ribbon cables between the halves of the case.

I would check your fingering... You MAY be late in hitting a particular note and the using auto chord... this can cause the problem. Another thing is if notes are hit with different velocity that can affect the sound. Sometimes certain voices have VELOCITY switching which actually changes the voice depending on the velocity you hit a note.

E5 flat and off pitch


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,

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.

Fredy 2 I am trying to play chords with my fingers, there is no sound, if it is on any other mode the chords work but i need it to be on fingered mode thanks doreen


OK... It wasn't clear from the original.

Sometimes the keyboard has a mode that splits for upper and lower part of the keyboard, usually splitting at the F#/G. Also CERTAIN voices will ONLY sound one note at a time. Piano setting would not have this problem of course.

When you play a single note does that sound? If it doesn't in the fingered mode, then there may be a processor problem in the unit/

If it does, there is probably a problem in the matrix that scans the keyboard electrically. If one of the keys were ELECTRICALLY stuck on, the processor within could not read whole sections of the keyboard.

To troubleshoot the problem, press exactly one key at a time... do they all work for say a piano voice while in the fingered mode.

Next press a key at the high end of the keyboard and try others. See if you can find an octave that fails to work.

The problem is likely imbedded in the electronics and could be anything from a dirty key contact to a cracked circuit board. It is NOT likely you can fix this yourself unless you are experienced in electronics.
