Yamaha has the manual for the PSR-270 keyboard on the product site: http://usa.yamaha.com/products/musical-instruments/keyboards/digitalkeyboards/portable_keyboards/psr270/ . Click on the support tab. The direct link to the manual (in English) shows in my history as: http://download.yamaha.com/api/asset/file/?language=en&site=usa.yamaha.com&asset_id=35052 .

I hope this helps.

Hi
I'm not sure I completely understand your problem but......it sounds like you might be in "Fingered On Bass" mode. This means if you play a chord like F using the notes FAC- if you play them in 2nd inversion (so the order is CFA) the psr-1000 will make the note "C" the bass note. In this mode if you played ACF then "A" would be in the bass part. Change to "Fingered Chord"-this will enable you to play any chord with the tonic (the name of the chord) F whether you play FAC, ACF or CFA in the bass part. I don't have access to a psr-1000 but often with Yamaha instruments this can be changed by pressing and holding the "Auto Accompaniment" button. I hope this helps.

Dead keys on Yamaha PSR e413 keyboard: Flip keyboard upside down, remove cover screws (use marked cardboard template to remember where they came out), spray suspect key-contacts with fast-drying contact cleaner, (usually a PCB with a matrix of contacts under keys), re-assemble base cover, wiggle faulty keys as far as possible to 'scrub' any dirt or oxidization. If this cleaning trick doesn't work, get a pro to check it.

Hi, i think you can. You can go to any of the Yamaha companies around you area and explain to them the problem of the keyboard. They will give you good and quality replacement part for your Keyboard.

Make sure you go to only Yamaha company to avoid getting a wrong part for your Keyboard.Avoid road siderepairsforissue like this,it's more complicated to handle

I guess that will do.

Thanks for using fixya...
