Try placing your ear on the speakers, adjust the volume control up and down several times, you should hear a humming sound that goes up and down. if not problem with the stage before the amplifier, that is the sound processor. if you dont hear the hum. problem with the amplifier and speakers, including the sound ports or jack. dissassemble the unit. look for loose connections from speakers to amplifier.

Psr 290. Where can I get a manual?


Yamaha has the Owner's Manual for the PSR-290 portable keyboard on the product page: http://usa.yamaha.com/products/musical-instruments/keyboards/digitalkeyboards/portable_keyboards/psr-290/ . Click on the Support tab and look the Downloads heading. If you want the English version of the manual, just click on the second link. If you would like the manual in another language, click on the More Downloads link.

The current link to the English version of the manual is http://download.yamaha.com/api/asset/file/?language=en&site=usa.yamaha.com&asset_id=2381 . This is a PDF so you will need Adobe Reader DC or a similar program.

I hope this helps.

I have a yamaha PSR 240 and one of the keys (E) won't make a sound. Everything else works perfectly except for that. I could not find a category for yamaha keyboards or musical instruments.


Yep, a key contact has got contaminated... You have to disassemble the unit to expose the keys.

You have to remove the offending key which is OFTEN tied to a bunch of keys. Under the keys you will find strips of silicon rubber with little domes sticking up. Under the domes are two contacts, either two black conductive rubber or sometimes a ring with a pill in the middle. These contact circuit traces with a black coating on the board under the keys. Clean the pills AND the circuit traces GENTLY with ONLY 99% isoprophyl alcohol. Reassemble the keys and the unit.

Be very careful handling, especially the ribbon cables between teh upper and lower halves of the unit.

Note there are TWO contacts per key which one closes before the other and that is how the key velocity is measured by the processor.

Yamaha PSR-510 Keyboard


There is no need for a manual. It is so easy to operate because it is designed for easy opeating. If you need a manual to operate the PSR-510 then you really won't be able to operate it even after studying the manual. But here it is just in case you can by some miracle!
