Yamaha PSR-275

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.

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!

Yamaha PSR 275 Keys

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.
