**privia px-850 making odd noise on left speaker**

[lana]

Hello all,

 

I turn on my privia one fine morning and it started making these noise like my video below.

hoping anyone with such experience could share on what’s the matter 😭😭 thanks much in advance!

Hi Lana, unfortunately that sounds like something a technician will need to look at.  I would contact a local repair shop and inquire about it.

Lana, what a terrible noise! I hope you can get it fixed. I have a different problem with a popping sound with my PX 850 as best shown in this Youtube that I found. https://www.youtube.com/watch?v=5lSEspHauEo . As you will see, they illustrate the problem but unfortunately, don’t give a solution and imply that the problem is with the way that the processor tries to synthesise the frequency and that therefore, it is inherent with the DP. I have seen other entries into this and other forums describing what I think is a similar problem with this and previous Casio models but no solutions forthcoming except warranty which does not apply to my 2^nd hand older unit. Although it is a different problem, perhaps my fixes may fix your problem too?

I should say that I am not a musician. I bought this DP on Gumtree because I have just begun piano lessons to help me with learning my part for the choir that I am in. So, I don’t need all the bells and whistles that this DP provides for good musicianship. However, this popping is not conducive to practice! I have two keys which produce the popping particularly when I use the damper pedal. My two keys are B5 and C5, so not the same as the keys shown in the video which were A5 and Ab5". The noise was sometimes v. loud and gave me a fright.  

I believe that I have alleviated the problem (at least for my use) in that the loud popping has not returned. I figured that the problem may have had something to do with reverberation. So, I looked at the manual and I have done several things mainly around reverberation.

1.    I did what the trouble shooting said to do with "sounds and/or effects sound strange" (4th problem in troubleshooting). I think it helped but didn't fix it;

2.    I adjusted the String Resonance per the instructions on page E7 of the manual. I adjusted it to Option 1 = Suppressed. This definitely made a difference. Of course, this means you are stuck with a suppressed string resonance when you may want more reverberation. Being a piano newbie, those subtleties don’t apply to me;

3.    I adjusted the hammer response per the instructions on page E7 of the manual. I adjusted it to Option 1 = Fast. (not sure if this made a difference);

4.    I adjusted the Reverb per the instructions on page E8 of the manual. I adjusted it to Option 1 = Off. This definitely made a difference;

5.    I adjusted the Chorus per the instructions on page E8 of the manual. I adjusted it to Option 1 = Off (not sure if this made a difference);

6.    I adjusted the Touch Response per the indications on page E24 of the manual. I adjusted it to setting 3 (Function + Ab6). This definitely made a difference. In fact, if you set it at touch response = off (Control + F6) the pop could be heard in another country! Counterintuitive I thought, but hey I am no muso.

So, the combination of these adjustments means that although a faint tapping sound can be heard from the left speaker(s) when striking my two problem keys especially when using the damper pedal, the tap cannot be heard above the music unlike the former pop which even for a complete amateur was very off-putting.

Of course, I am guessing if you disconnected the left hand speakers, the problem would be solved too but that would definitely compromise the DPs performance. I hope this means that you can solve your problem too. Good luck.
