Dear Sumtiro: Your keyboard was released by Yamaha in 2007, making it relatively new. I suppose the warranty is no longer valid, and I would strongly advise you to check with the store where you bought it to see if they can have it repaired. Above all, do not attempt any repairs yourself. The only actions you can try: Check batteries if you use them in your unit. Weak batteries can sometimes produce low volume and buzzing. If you are using the Power Adaptor to energize your keyboard, have a technician check its OUTPUT and the Jack (where the Adaptor enters the unit) to see if it is dirty. Your keyboard is a complex electronic machine, and I must repeat, DO NOT ATTEMPT TO REPAIR IT YOURSELF.
Good luck.
