Yamaha P250 pedal won't sustain

by micki
(Washington State)

When I press down on my sustain pedal on my Yamaha P250, it doesn't sustain. I've had this problem before and it had to do with the order that I plugged in the keyboard, the pedal and turned the power on. I have tried every thing and it still won't work. Does anyone know the secret? I think the pedal still works, because if I plug everything in a different order, then I get sustain all the time....so confusing..help!

my pedal won't sustain either
by: Anonymous

I have had this same problem over the years and now it has stopped working completely. Will buying a new pedal help or is it an electrical problem?

replacing damaged key - Yamaha p250

by mike
(lisbon iowa usa)

I caught the top of the key on a fingernail while putting the Yamaha p250 in a case. That damaged the key and it is sticking. I opened the case and can see a split in the plastic. What is a procedure for removing and replacing key?

Replacing Damaged Key
by: Alfred

Dear Mike: I am not familiar with your unit, and cannot guide you as to the procedure required to access and replace the key. I suggest you first read my comments re opening keyboards (see Q & A title to the left of this message. and if you disagree, and wish to DIY, you can go to the Yamaha main site where I believe you can seek help from their technical department.

I'm unable to provide the guidance you need, as to do so, one has to be a qualified technician in (all??) Yamaha Keyboards. This Forum is generally for comments related to "non-invasive" (keyboard opening)procedures. You may encounter a member who has the technical experience to come to your aid, but short of that, I recommend you consider my above recommendation. Good luck.

key replacement
by: mike

Thanks for your input... but I met a very
qualified Yamaha piano technician at a local dealer who was filled with the christmas spirit. He offered to repair keyboard through the store ind time frame of 2 weeks. When I explained that I needed it for gigging this weekend he offered the information I needed to replace the key... I must explain that I am an engineer/technician for an aircraft instrumentation company and involved the piano technician in a technically detailed conversation. When he sensed that I could handle the repair he explained the procedure. I had ordered the part overnight and made the repair the following day. Yamaha makes the best electronic grands. thanks

Yamaha P250 - input power supply requirement

by David
(Durban South Africa)

I wish to run my Yamaha P250 off an inverter supplied by a 12V battery. This for street busking.

I need to know the size of the inverter to use.

Ta.

Busking with Yamaha P250
by: Alfred

Dear David: Your question appears to be one not frequently discussed in this Forum. I?ve had no experience with inverters, but in a quick sweep of the Internet I located a site indicating an ample (estimated) 50 WATTS. Maybe this helps. Hopefully some other better-informed member(s) will soon come up with a timely reply. Good luck.

Related Question
by: Anonymous

This seems to relate to mny question about how powerful a step down transformer i would need to run my p-100 in a 220v country. Can I assume that if 50Watts is enough, a transformer handling 250 watts would be more than enough?

P 250 Key Problems
by: Alfred

Dear Sab: Refer to and read Mantius', Dick Rector' and my comments in the Q & A title to the
left of this message, then decide if you know what you are trying to do. I'm guessing (as my records are not complete) that your unit is relatively new, so follow our advice and do ONLY the following: Blow out the spaces around the offending keys, using a can of compressed air, then follow with a STRONG vacuuming. If keys still stick, try VERY MODEST talcum powder dusting (applied to thee same spaces) with a small water color brush). Work the offending keys up and down as you proceed. Finally, be sure you keep your keyboard covered when not in use.
If the above does not cure the problem, seriously consider having a qualified technician repair the unit. Please do the favor of posting a follow-up message in this Forum so other members can profit from your experience. Thanks, and good luck.

keys not working
by: Dick Rector

Hello Sab,

This is NOT an official Yamaha tip but it worked in some cases.
First try a can with compressed air to blow dust, dirt or even foreign objects away.
Get a vacuumcleaner (I think in England you call it a Hoover) carefully on the keys.
Use a drinking straw to blow a little talcum powder (babypowder) around the sticking keys, that works as a dry lubricant. If this doesn't solve the problem you have to take you board to an expert repair-person. Getting new keys is very difficult and replace them for the old ones is NOT a DIY job.
Let us know if the advice worked so others can benefit from it.

Success and regards
Dick

SOLUTION
by: Sab

Hey guys,
thanks for your advice but in the end i called yamaha. After they checked the serial number of my p250 they said that it was part of a large batch of p250 yamahas that had a fault in the key bed. They replaced the keybed FREE of charge and now its like a brand new piano. So id advise anyone with similar problems on their p250 to check their serial number with yamaha.

(Its also worth pointing out that yamaha advises that replacing the keys yourself whilst temporarily fixing the problem wont last for very long, and will keep reoccuring until the keybed is replaced, and they do this replacement reguardless of the unit age).

Hope this feedback helps.
=D
