Really interesting thread but what amazes me is some of you were waiting until your warranty runs out .. surely Casio should be fixing this for you under its warranty and in some cases they fit a totally new keyboard frame. It has to be cost effective to do this by taking it back to where you bought it (if not long distant posting - which could have damaged the assembly set up even before you started using it from new) .. lets face it - it arrives in a large cardboard box and the key parts are only taped down not bubble wrapped but the inners are not extra packed at all. Normal long distant handling and trasport shake can do quite some damage and we would not even know. Cushioning strip parts are available from Casio although the largest one of the 4 is quite expensive (about $25) the next largest around $10 .. the smaller 2 are about $1 then comes tax and posting. In my case in the Uk it was around £35. Personally I think the Casio research team should be doing more to make their keyboard system more reliable or if not - make it in a way that it can be easily repaired without a lengthy timeframe .. it is one or the other if they want market share against the likes of Roland and keyboard leader by far - Yamaha I had a quote from a casio engineer recently and they want £150 call out min plus parts but didnt say how many hours that included in the deal or if it includes the return when replacement parts are known and ordered for 2nd fix. It's a recipe for customers to be conned for sure. I have a PX-850 which has noisy key syndrome on some keys which I would love to get fixed and all this information is helping me decide to try do it myself. I also have a PX-760 which is still working fine and no key noise .. obviously the 760 is younger by a couple of years but they both have the same keyboard set up and frame as confirmed by Casio UK although the part numbers are different. My wife uses both pianos in 2 local schools for Covid distance teaching by using 2 pianos which she will continue to use as the children are used to having their own piano. Both the other pianos are Roland HP's since 15-16 years and are still playing nice and no key noise. That has to say something. Hp's are not that more expensive that the top PX Casios yet they seem to last far longer. One word of warning from a call to an engineer - it seems Roland will not be stocking parts for DP's over 10 years old or so he says ... I cannot believe this so have pinged off an email to their HQ to find out if true and wait to see thier response - thats assuming they will be honest to a customer. Amazing how Casio Roland and Yamaha are all Japanese yet they have such a different quality build level between them. Seems Casio are great until they have noisy key syndrome and are destined for the plastic dump because it is too hard to repair them with any ease. hats off to all of you that have tried and suceeded.

Thks Duinsel ... even today your thread helps even me today on my purchased PX-850 as I need to sort out some rattling keys after a recent 2nd hand purchase for our local school. One thing may I point out is your last video picture ... the bottom left cushioning strip seems to be on the wrong side of the plastic shelf as per the Casio parts service manual .. your video shows the strip as being under the plastic shelf when it should be on the top (look closely at the bottom left of your vid capture on pause) .. it may be just the way the vid was taken ? There are 4 cushioning strips on the Privia keyboard main frame ... 2 top (back and front) and 2 bottom (back and front) part number 66 front bottom (thin) cushions the larger downward fin of the white key (back of the U shape) 67 front top (thin) ... this one looks like it is in the wrong position but it should cushion the front bottom lip (front of the U shape) 68 rear top (medium) looks like a white licorice allsort strip just at the back top of the key action ... and 69 front bottom (large) cushions the rear of the hammer action I am waiting for the parts to arrive but have also bought some draught strip, some furniture cushioning strip and extra 3m double tape off Amazon just in case I can do same with that. Time will tell. Luckily i also have a PX-760 in my other school where we teach and the parts are exactly the same and the whole keyboard layout is also the same but the part numbers are different .. nrs 56/57/58/59. This is worth knowing as the PX-760 is still being sold whereas the PX-850 is discontinued. Hope this helps
