my yamaha keyboard has worked fine until now. when i went to turn it on, there was a brief light & then dark again. sometimes i don't even get a blip. does the same thing on other outlets. how can i tell if it's the adaptor or keyboard & how can i fix it? thanks

I had the same problem. I tried to switch it on and then a brief light and noise from the speaker, then it went dead. I found another 12v adaptor plugged it in and the Keyboard sprung into life! Brilliant!

My cord is fine. I tried more than one. It is the connection inside the keyboard that is loose. When I wiggle the cord, the power will come on. The little connector box inside is not study. Oh my god, my husband is going to sauder the thing to stable it. I hope he don't ruin it. This is my problem. I wanted to take it to be fixed.

What is the make and model number of your keyboard? It may be that there is a replacement part available which will make it easier to replace the power socket in the keyboard than to attempt a repair on one that may be broken.

arch, I would do this be exclusion. Use a multimeter and measure the voltage on your adapter. The inside of the barrel is positive and the outside negative. Set your voltmeter to DC voltage and see what you get. A lot of times the wire around the barrel breaks and you may have to wiggle the wire a bit. Should your voltage be as required, it is safe to say your adapter is working as designed. Then you have a keyboard issue.

Thank you old turkey, I don't have a multimeter. Is there some other way to test the adaptor? when you say "wiggle the wire", do you mean the cord or do I need to strip something away? If a wire is actually broken, how do I access it to reconnect or is there something else I can do to fix the adaptor or is my only option to replace it? Thanks, again

DC CONNECTOR SIZE - 2.1mm The DC output connector plug should be wired as a Positive Centre Tip type connection. An adapter power supply with a positive tip indicates that the centre (tip) of the output plug is positive (+) and the barrel of the output plug is negative (-). Here is an image which shows what to look for to ensure that the adapter's DC Output plug is a Centre positive tip. This picture is usually stamped on to the body of the unit or within the owners manual.

I just plugged my keyboard this morning and it makes one sound I'm not familiar with,then the sound stop and ,and again once I plugged the adapter it turns on automatically without pressing the power button

I had the same problem but with the E353. When Yamaha sold me this keyboard it came with an unregulated power supply (not fixed at 12V) so I changed to one fixed at 12Vdc (regulated) and was the end of the problem.

Took out 14 screws on back and undid 2 leads carefully to separate base assembly from top. On rear of power connector soldered small piece of flexible wire from J503 link wire to adjacent pin. (Connects to the centre pin). As added mechanical support glued connector to the PCB. Re-connect 2 leads making sure to support the PCB while pressing the connectors. All OK now!
