I get a loud hum when I turn my keyboard on. This happens whether I'm using the internal speakers or external amp.

PSR 520 Hum
by: Alfred

Dear Kevin: The problem you describe indicates that there is a "Ground" or a "Short" in YOUR KEYBOARD. The external amplifier has nothing to do with the hum. I would counsel you to take the unit to a professional for checkup and repair.

Cartridge not loading
by: Dick Rector

Hi Jock,

Can be a lot more but try to clean the contacts on the cartridge with (don't laugh)a pencil-eraser or stiff toothbrush!!! These copper contacts can get a thin layer of oxidation if not used for some time. The contacts in the keyboard are hard to reach but sometimes when you carefully wiggle the cartridge in it or pull it out and push it back in, it might do it.

Hope this solves your problem but as said it can be a lot more like a broken cartridge or electronics in the keyboard.

Good luck
Dick

No Power - Yamaha PSR520

by Pizzazz
(Baltimore)

I have PSR520 and am getting no response when it is plugged in. I use a 15mA Max adaptor which has worked perfectly in the past. The adaptor still seem to work with other instrument that needs less current. The thing is I have not played my keyboard in a couple of years. now I get no response from this adaptor.

Could I just need a new adaptor or do I need a new keyboard?

Power Yamaha PSR 520
by: Alfred

Dear Pizzazz: Some food for thought:
1) Your 15 mA Adaptor may have a defective Secondary winding, still strong enough to power another keyboard, but no longer good enough for your Unit. 2) The Plug of the Adaptor may need cleaning with Electronic Contact Cleaner. 3) The Jack of your Unit may also need the same treatment. 4) Replacing the Adaptor seems to be the most practical move at this time. 5) Weigh the price of a new keyboard against repair cost(by a qualifieed technician - preferably Yamaha) tnen make a decision which suits your budget.
Hope this helps. Good luck.

Main Screen PSR 520
by: Alfred

Dear Helmut: Refer to my post of Oct, 3 in Q & A at left of this message. You may be "playing with fire" if you try a DIY approach to your problem. Yamaha Displays are (unfortunately) expensive to replace and the work should be done either by Yamaha or an authorized technician.

Main Screen PSR 520
by: Alfred

Dear Helmut: Yhanks for kind words re my 10/3 post. In my haste to dispense advice I overlooked your question concerning replacement of the PSR 520 (released in 1995 by Yamaha). Depending on your budget, you can consider the following approaches. 1)Good store for keyboardsis Kraft Music (ebay@kraftmusic.com or phone 800 7833368) 2) Ebay itsewlf (under Keyboards -new & old units). If you contact Kraft, be sure to indicate your level of expertise and have them guide you as to a choice.If you go the Ebay route, take your time to understand the descriptions given . If new, the keyboard will carry a warranty. If used, be sure you bid on one which is confirmed as being in 100% working condition, comes with a Manual, Adaptor and a Return Option. Good luck.
