starstarstarstarstar 		Ref Yamaha PSR E433 NEW
by: Anonymous

Recently all the E & F keys stopped playing on my keyboard.

Symptons:- If the F Key was held down the E key would not play and visa versa.

The fault was intermittent as sometimes everything was fine.

The keyboard is played in the conservatory in a clean environment so I didn't think that dust would be the problem

I finally came to the conclusion that it may be caused by condensation trapped in the keyboard damping the internal circuits.

I did not wish to open up the keyboard so installed the dehumidifier in the conservatory.

This seems to have solved the problem as everything is now working fine.

I hope this will be of some help to others and thank you for helpful comments by others

starstarstarstarstar 		Shook my keyboard back to working order! NEW
by: Anonymous

Every 6th key of my keyboard was dead. Turning my keyboard upside down and smacking it was not working a whole ton, but picking it up upside-down and shaking/tilting it was releasing a rainstorm of dust and immediately fixed the issue.

If your keyboard is a bit older and is having similar issues, there may be dust on an internal sensor somewhere. Using compressed air may work? However, it's important to actually get the dust out of that thing. That fixed it for me, hopefully it does for you reading this too.

by: Anonymous

I've had this Yamaha P-125b for almost 3 years now. It has performed well until yesterday, the C# key malfunctioned. When I press it normally, it won't make a sound, but when I do it hard, it makes a loud noise. It seems this key lost it's soft touch response and would only work on *forté*. I tried cleaning it, slapping the back of the piano but it still won't work. Please help, thank you

by: jaydouble

Please don't take apart your keyboard apart as Yamaha suggests. Hold the function key down and press G6, which sets the tuning to default*. Sometimes that won't work by itself, so toggle between 1 step down (F#6) and 1 step up (G#6) ending up on G6 (normal tuning).
*I use a P35 and P45.

by: Anonymous

I have a problem with my Yamaha e373. I just bought this keyboard few months ago. Sounds fine, until all of my C# and G keys were all having trouble. These keys lose its touch sensitivity and sometimes doesn't sound especially if you are pressing it multiple times. The problem is also ocassional. Sometimes its fine, other times it's not. I've already cleaned my keyboard, and still the problem persist. Does anyone knows what might cause this problem to occur? And how to solve it permanently?

starstarstarstarstar 		Keys not working on Yamaha keyboard
by: Anonymous

If a few keys on your Yamaha keyboard are not working, it's possible that there may be a problem with the key contacts or the circuit board that controls the keyboard. Here are a few steps you can take to troubleshoot the issue:

1. Check if the keys are physically stuck or damaged. Sometimes dirt, dust, or debris can get lodged in between the keys, preventing them from making proper contact with the circuit board. If this is the case, try cleaning the affected keys with a soft brush or compressed air.

2. Check if the keyboard is in Local Control mode. If the Local Control mode is turned off, the keyboard may not respond to the keys. To check the Local Control setting, refer to the owner's manual of your keyboard.

3. Check if the keyboard is in Split or Dual mode. In these modes, some keys may be assigned to different voices or functions. Try switching to a different mode or resetting the keyboard to its default settings to see if this resolves the issue.

4. If the above steps do not resolve the issue, it may be a problem with the key contacts or circuit board. In this case, I recommend contacting a Yamaha authorized service center in your area for further assistance. They will be able to diagnose and repair the problem for you.

I hope this information helps you to resolve the issue with your Yamaha keyboard. Best of luck!

After I took my keyboard out of storge, where it had been standing on one end, all my B-flats and my E's stopped working, in ever octave.

I saw this technique also on a YouTube video, and it didn't work for me after about three tries.

I googled again the next day and found THIS page, and the comments about people trying several times, plus the advice about smacking it on the back, prompted me to try it again.

After the second one, in which I definitely smacked it on the back, everything worked!!

starstarstarstarstar 		Dead Keys Fixed!!!!!
by: Ronbo

Like others who posted here, all of a sudden, all my B and F keys on my EW300 went dead. Everything else was still working flawlessly, but how can one play a single song without 2 of the 12 tones in all octaves?
I was all ready to take the machine apart and try to clean it when I read the, 'slap it on the back solution' that worked for several others. I thought it was plum crazy, but I figured, what could it hurt. Sure enough, a few slaps on it's rump and it is working flawlessly again! That is without a doubt, the fastest, simplest, cheapest and weirdest fix I have ever heard!!
Thanks!!!

starstarstarstarstar 		backrgound why tapping helps
by: Ridje

With the help of service manual I determined how does this thing work; keys are bound in groups of six (so a single octave is made of two such groups), each key has two switches on it; when you press the key, you connect a wire which stands for the group with one of the six wires in a single group. So it is quite common you will see faults in halves of octaves.
This keyboard is not very well protected against the debris entering the guts and this is probably the reason keys stop working - when you tap it, you dislodge the chunk from the PCB where it is causing fault. So it is probably not a very long term solution. Mine was to thoroughly clean all the insides.

I had keys not sounding in a PSR 260, same note names in multiple octaves. "Ah," thought I, noting the pattern, "that must be a software issue." So I did a factory reset. No luck.

So I scraped the bottom of the barrel and ended up here. and when I read that the answer was to 'Hit It', I thought, "You've got, to be joking," but still I tried The Big Slap.

It didn’t work: about 3 or 4 times. I re-read the posts, including one about slapping on the underside. It worked. I can hardly believe it.

But Thanks Guys.

starstarstarstarstar 		Why slapping works
by: Ben K

I recently took apart a P105 with this issue - symptoms were some missing Cs and F#s. I slapped, which fixed some keys and broke others. Inside the case are two thing metal ribbons connecting the keys and panel to a main board. I reattached the ribbons while the keys were out of the case, and lo and behold it works. My guess is that these ribbons somehow get loose over time, and slapping somehow pushes them back in a little bit.

starstarstarstarstar 		Yes, it works
by: Anonymous

The owner of the P-115 said some lower G's were not working. When I looked it over, those keys were working, but some higher keys were not. I took the keyboard apart and cleaned the contacts under the keys. After re-assembling the keyboard, the dead keys were now working, but the two highest C#s and Gs were not working. I found a video that showed this "slapping" technique, and it worked!

I wish someone would reveal what this is actually doing to fix the keyboard.

Four keys on my Yamaha P115 just stopped sounding (regardless of voice style). Keys were C#5, G5, C#6 and G6 a curiously linked set of pairs. Tried switching on and off, re-initialising etc, all to no avail.

Rather sceptically, I felt there was nothing to lose in trying the slap technique described here. Two sharp slaps on the back and underside and everything's working perfectly again.

I opened up my keyboard before reading about the slapping solution. Since I already opened the keyboard up, the only problem I have is taking the keys out, so I can clean the dust from underneath. It seems I have to slide something out, but it's very difficult to do so. If anyone has repaired a PSR-48 before, can you tell me what I have to look for or what I have to do, in order to remove the keys.

by: Anonymous

Electrical contact cleaner and lube will remove dirt and oxidation and the residual lube restores conductivity. The length of time between the 2 contacts when the key is played determines the volume and attack. Very cheap method for "touch sensitive" keyboards. Works if all cantacts are working. It is not rocket science to dissassemble clean and reassemble but there are a LOT of screws and it is rather time consuming. You might just want to buy a new and better quality keyboard. You'll be glad you did.

So I just Plugged in the cord for PSR-E353 and I automatically started to play a song I knew from memory. When I noticed my high E wasn't playing until like 10 seconds after I pressed it. I tried to play all my E's and none of them played.
Please help me!

starstarstarstar 		B# key isn't working on my PSR 320
by: DYW14

The only single b# key isn't working on my PSR 320.
I tried to opened it a few times but couldn't open the part that holds the keys (which says ABS on the black part) and rubber parts together with a lack of tabs on the back to open it to clean the b# key out. Any suggestions of how I can open the
black ABS part so I can play my old keyboard again?

by: island guy

I have a Yamaha P-105 weighted action keyboard. Playing it today I noticed a sudden sharp volume increase, followes by the bottom two G’s going dead. Living on a remote island, I felt screwed! No easy solutions, maybe even time for a new one.
Watched one tutorial showing how to open it up, remove keyboard sections etc. Then I saw this thread of folks solving the problem with some shaking and slapping! Worked like a charm! Thanks eveyone!

by: Don

Most of the e's on my Yamaha keyboard stopped working or would work intermittently. I unplugged it, turned it over and slapped the back cover several times, shaking the keyboard vigorously at the same time. The e's started back working. Hallelujah!

starstarstarstarstar 		PSR 520 rubber membrane replacement
by: Walter

I cleaned the contract strip on my PSR 520 but see that the orange rubber membrane for the contact of the low E is worn and broken -- specifically, the ring around the "nipple" for that low E key. The key played again for a while but I guess the nipple (with the contact for the contract strip) got squished out of alignment again. So now the E is dead again. I would like to buy a new membrane strip but don't see parts for the 520. Does anyone know if the rubber membranes for other models of the PSR would fit in the 520. Maybe the models just before or after the 520?

by: Champ

We have a PSR-275 and last week it stopped playing every G key.
Today we found this thread and it mentioned rapping on it. So we took one of the kids large dragon toys and just wailed on it a few times. Now it works just fine. Problem solved. Thanks!

by: Larry F

Hi all,
I was given one of these keyboards for my 9yo Daughter. It had a few keys that did not work.
I am an electronics tech and the first thing I did was remove the rubber keypad membrane and give the little "black" buttons attached to the rubber membrane a firm quick rub with a cloth with alcohol(or methylated spirits will do). I also wiped over the PCB contacts gently with the alcohol and cloth. allow a few minutes to dry and reassemble taking care to carefully lay the rubber membrane back into position correctly. Make sure all the membrane sits flat(very important). Use this opportunity to clean out dust and fluff from the area. These type of rubber black buttons are found in TV remotes, cordless phones etc and the remedy is the same. The rubber is impregnated with a conductive material, but after time the rubber deteriorates and the conductive material is no longer effective. Giving the button a rub with a cloth and alcohol rubs away the perished rubber and exposes fresh conductive material. Problem solved.
cheers
all

starstarstarstarstar 		easy to fix
by: Anonymous

I also have a 275 keyboard. didn't use it for a while; more than 6 months. 5 keys stopped working. Removed all screws on the bottom including the2 long ones in the battery compartment, really lifted up on the white plastic tabs on the battery wire, disconnected that wire, lifted up on the white tabs that attach the keyboard to the processor, situated those 2 flat cables (be careful not to bend the tips of the wires), then there are 2 contact boards under the keys. Don't have to remove any more screws at this point. There are large black clips and small black clips holding the board in place. I only had 1 go out, it was the upper register. Gently push in on the small black plastic clips starting at the outside and move in while gently lifting up on the board. It will easily come out. Be careful with it. I used a Qtip and acetone free mail polish remover and cleaned all the little rubber contacts and also the black pads on the board. I took the wires off the board before I took it out btw. Assembly is the opposite of above. Very simple. Only need a Phillips screw driver to perform this. All keys worked perfect afterwards. Good

starstarstarstarstar 		Fixed this same problem for myself
by: Sully

I had this same issue with all of my F# and G keys. I was able to fix it pretty easily. I unscrewed all of the screws on the bottom (don't forget the two inside the battery compartment). The case opens easily and then you can disconnect the cable that connects the battery compartment to the main board (this just lets you operate a little bit easier).

I then cleaned a lot of white residue off the piece where the key presses against the belt - I was shocked at how much build-up there was in there. I used a screwdriver wrapped in a soft cloth to wipe each key down then blew the whole thing out with compressed air. After doing this, the keys all started working again. Hope this helps!

Dear Stuart: I own a PSR 273 which is the same as your PSR 275. Apart from that, I believe your unit has deteriorating rubber underlay pads, and would recommend you contact.....................
Puretech Solutions, UK ? (Yamaha-approved Tech. Svce. www.puretechsolutions.co.uk ..............

Have Model and Serial number at hand, and explain your problem. Hopefully they can help. If there is any charge(s)for any repair(s), it should be well worth the investment, so that you can continue enjoying your keyboard. Good luck.
