#2262831 - Yesterday at 11:52 PM Yamaha P140 sluggish keys : how to fix?

I bought a second hand Yamaha P140 4 months ago, as my first DP. Now that I gained much more experience at playing piano, it becomes obvious that the keyboard has some significant defects : all the keys are noisy when firmly pressed or released and, most importantly, some of the keys have a slightly more sluggish action than others, making playing on the P140 harder than it should be and very much less satisfying. I assume whatever dampens the key when it is firmly pressed or released (some sort off wool pads, I believe) has hardened, causing the noise, and the sluggish action might be caused by some debris and dust. Would it be advisable to open it up and attempt to clean it or should I just list it on Fleebay and buy a brand new P155? Option #1 might save $500-$600, but I wouldn't want to worsen its condition...

Cheers !

Hi Bambell,

Replacing the felts (there are two of them) by yourself is absolutely possible, provided that you find a place to buy the replacements from. Search the internet for suggestions.

You may for example start from this page and this page to have an idea of how that can be done.

Most Yamahas should be pretty similar.

Good luck,
Paolo

I don't know specifically about Yamahas, but noisy keys can be caused by a number of things, such as parts becoming loose and knocking together. The video linked by Paolo70 is useful if it does look like the felts are the problem. If so, I'd expect the noise to be more pronounced on the commonly-played keys, rather than all of them. The sluggish keys can probably be repaired by cleaning and re-greasing the joints. It may be worth finding out the specifications of the grease used on the joint in question, so that it behaves the same as the other keys.

Go ahead and open it up - it's hard to break anything so long as you take reasonable care (in particular regarding fragile wire connectors between the various parts). Sadly, repair guides are hard to come by if they exist at all, so you're pretty much on your own, but if you do work it out, post details here to help anyone else with the same problem. smile
