Try this first with the piano off, run the control from stop to stop rapidly several times. The object is to clean off any dust deposits and shine the contacts inside the pot. If the pot is not damaged beyond repair, then this should fix it.

SOURCE: casio ct 636 e-piano LOW volume on all keys and instruments

Sounds like the built in amplifier is going down. You could put it in to a music shop and have it repaired or buy a small 10 watt amplifier and plug in from you headphone socket to the amplifier. I suppose it depends what is the cheapest way to go and how much you are prepared to spend as the keyboards are pretty cheap nowadays especially on Internet shops.
Good Luck

SOURCE: Scratchy volume potentiometer

Try cleaning your volume potentiomenter with contact cleaner (they come in spray can's), the scratchy sound is audible when you turn your volume control on, the contacts inside your potentiometer accumulated dust or some other particles.

SOURCE: what potentiometer is being used in rbx 374 bass

Yes, active use different value pots than passive. The volume control is LIKELY an "audio taper" which can be either an "A" or a "B" marking as there is confusion about the marking. The resistance is likely around 500K ohms down to as low as 50K ohms. The marking MIGHT be something like 504 B or 503 B or the same with the letter "A".

An A500 pot might be only 50 ohms... That would result in very low output. Again, the marking in the industry is not consistent.

Best bet is to get the part from Yamaha. Go to Yamaha America "parts" dept in California. You can search the phone number with Google.

Beofore you replace it, if it is only scratchy give it a good working by sliding it back and forth a rew dozen times. (if it is a slider type) If you can get some electrical contact cleaner with a thin plastic tube, try squirting that into it and work it again, if that fails, then look at the volume control replacement.

How do i adjust the drum rhythm volume so it is louder than the tone settings


You ay have to edit a rhythm and save it as a "user defined rhythm". During editing the volume of each part can be defined with vol. level ranging from 0-127.

Please read the manual.
Metronome volume can be easily changed by just holding the metronome button.

Tip

Electronics spray cleaner


The most common problem with guitar amplifiers

and other electronics that are making noise or cutting out

or sticking and not working correctly is a simple fix...

I use Radio Shack electronics spray contact cleaner

for most of my basic repairs

in the pictures posted I show the basics you need....

some screw drivers, basic knowledge, paper towels,

electronics spray contact cleaner, and a knife

First I carefully remove the nobs (volume control, tone control, etc...)

I use napkins to mask the area and keep from scratching the surface

Then I carefully spray into the (control} and work in back and forth....

the Best way is to spray directly into the potentiometer

that requires access to the internal chassis

on a quality pot there is a Notch that you want to spray into

on a standard pot just spray....

this will repair any scratchy noise or sound that cuts out

on guitar and bass amplifiers,

also can be applied to many other common basic sound problems



I hope this helps someone out?

2 possibilities: Dirty control/cursor...clean with electronic contact cleaner. NOT WD-40 IT IS A CORROSIVE CLEANER.
Or bad control or connection to control. Get access to the "underside" of the control and check. Hope this helps.

Turns on but there is no volume


If the volume control is analog (meaning it is an old rotary and not digital) - it may just require cleaning.
Pick up a can of electronic switch cleaner.

The volume conrtol knob on my Casio Privia Px-320 doesn't work. The volume won't go up or down and the knob feels loose. Can I fix it at home?


I found an answer at the end of this page: http://music-electronics-forum.com/t31080/ After replacing the potentiometer volume is OK. The original potentiometer has a very delicate axis.

First try spraying a bit of CRC226 (aaaaaa9make sure it is 226 as there are other products with similar numbers there)available at Home Depot in the electrical dept. into the control where the leads go into it. You may need to bend the plastic spout of the spray can at 90 degrees near the end to get it to go up into the control. This has a high probability to solve your problem.

Getting replacement controls that exactly fit are a major headache from anyplace than the original manufacturer.
