My metronome time signature has no sound although it is working and can see that on the screen. Have turned it upside down, slapped it but still no audio sound. Any recommendations?

Another alternative fix ?
by: Anonymous

If it helps anyone. I had a dead key on my Yamaha keyboard E363. After slapping which did not work I grabbed the failed black key at its fulcrum point and pulled it gently upwards whilst giving it a wiggle and it started working ok.

I have a fixxxx!!
by: Robbi

Hey guys!! If you are like me and have been scrolling through here for hours trying to find an answer, please do not take apart your keyboard yet! None of my E keys were working in any active, here’s the fix! What you want to do, is turn your keyboard completely off and then this might sound weird, but slap the back of your keyboard twice, and if it doesn’t work do the same to the top by the controls. It should work well!! I have a pretty old Yamaha. It is a YPT-300 :) hope you can get it working!!

Slap Technique Failed????
by: Scott

My son and I have a P-125 had some liquid in it. After unscrewing the top and removing condensation with a paper towel, we attempted the slap technique and the c and f# keys still do not work properly...when we press these keys they play once and then takes a long time to fade out, preventing us from playing the key again. I would appreciate any advice!

Scott

Hi all, I have had similar problems. To fix is easy enough if you have the confidence with a screw driver. Take off the top cover and use an alcohol wipe to clean the keybd contacts by lightly wiping them. reassemble and you should be good to go.

PSR-48 Repair Help
by: Anonymous

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.
Note: I've unscrewed the entire keyboard (At least, all that I could find).

Clean contacts and finish with contact cleaner
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.

Bottom 2 octaves, F# and G# stop working. Top 3 octaves, A stops working. Turning it over and slapping it works sometimes, but very random and am afraid to damage the rest of the keyboard due to repeated slapping. Keyboard has been dissasembled and cleaned multiple multiple times and no such luck. Sometimes all keys will work fine, but back to being broken after about a day. Any ideas?

Yamaha PSRE363 F# AND C
by: Jeoff

F# and C on my psre363 stopped working, on every single octave. They will play after a while and stop after a while. I had the same problem with Eb and A but I haven't had it for a few weeks now. I tried the slapping methods and hair dryer methods. Slapping didn't work and the hair dryer melted some keys together so I had to swap them with another keyboard I had laying around. Any other methods before I open up or replace my keyboard?

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?

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!

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?

Yamaha PSR-275
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

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

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.
