buzzing of digital piano

[aewanko]

some keys in the middle part are creating a buzzing sound. what do i do? is it time to buy another piano?

What is happening is that some of the keys in the middle are causing something to resonate either inside or outside the keyboard. Generally, a decent electric piano would be designed so that no resonance would occur due to the instrument, but it is possible that a build up of dust or a loose mechanical part inside the instrument is causing a bit of gip.
There are any number of things that could cause this - do you keep anything on top of the piano? - is the stand correctly attached? - are the pedals in good order? etc.

If it the piano itself that is buzzing, I would give it a clean and, if you can, open up the casing and check/clean any mechanical joints. I suppose you could try moving it to another part of the room and see what happens then also.

ok i'll try but i hope this fixes it.

It could be a glass of water, tea cup etc somewhere in the room aswell. Sound is a strange thing.

nope. it was very hard to disassemble and little or no dust. buzzing still happens once in a while

How irritating.

Perhaps it is something in the room then causing the buzzing. I remember once going around everywhere and changing the position of each object individually until I eliminated the source of buzzing. It is a quite tedious process though and again, no guarantees of success. Do you still get the buzzing with headphones on? Have you tried moving the piano to another position in the room, or indeed another room?

Sorry that there is no quick fix answer, but there are hundreds of possible causes to this and it is always specific to an individual case.

Good luck,

Hi, I'm new to forum...  nice topics and discussions.
If the piano has internal speakers (not a good idea, IMHO, they are never good enough) then you will have to seek out where it is resonating, may well be inside the unit.
I play a GEM PRO-1 keyboard (no speakers, of course) feeding a large stereo amplifier (about 40 wpc) and large Hi-Fi speakers than can nearly reproduce low-A (27.5 Hz.)  It used to be in the basement (now moved upstairs) and I've had one or two resonances to debug over the years.  In every case it was in either the suspended ceiling or the wood panels.  The solution was to bang around the room in a "scientific manner" <g> until the buzz stopped.
Since moving it all to the sitting room (normal paster wall/ceiling construction) I've not had any buzzing to fix at any playing level.   
Good luck.
Cheers,
Roger
