Try a Factory Reset. Try a power reset first. Disconnect from the mains plug for 15 minutes.

Try a master reset to start with.
Turn keyboard off
Turn on whilst holding down highest note on keyboard
Once screen display has complete release key

This will reset to factory settings.
If this doesn't work report back and we can maybe try other solutions.

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.

Is there a pattern to the wrong notes ( eg all up a semitone ? )
If so you could have altered the tuning.

Try a master reset:

Hold down top key whilst turning on. This will reset to factory setup.

See attached for individual reset procedures:

According to the manufacturer, the reset procedure is documented here and on page 42 of the instruction manual:
http://faq.yamaha.com/us/en/article/musical-instruments/keyboards/digitalkeyboards/portable_keyboards/psr500/656/2085/psr500-psr500m_factory_reset_procedure

Turn OFF the Power.

Press and hold the 'Custom' [RECORD/END] and [CLEAR] buttons.

Turn ON the power. The screen will display 'clr'.

Release the 'Custom' [RECORD/END] and [CLEAR] buttons.

Hi, Does the error actual say anything?
Have you tried a factory reset ? Hold down top white key while turning on.

The computer processor in these is NOT subject to the viruses like PC's are.

Do a factory reset on the keyboard to restore factory settings.

I would do a factory reset. Search Google for: factory reset PSR 2100.

It will be holding certain buttons or keys down when powering on.
