Yamaha PSR-510 Keyboard

It's difficult to say exactly what could be causing the lines on the display of your Yamaha PSR S550B without more information. Here are a few things you can try that may help resolve the issue:

1. Restart the keyboard by turning it off and then back on again.
2. Check the connection between the keyboard and any external devices (such as a computer or amplifier) to make sure it is secure.
3. Check for any visible damage to the keyboard or the display.
4. Try pressing the "Reset" button (if your keyboard has one) to reset the internal settings.
5. Check the owner's manual for any troubleshooting tips specific to your keyboard model.

If the issue persists after trying these steps, it may be a good idea to contact Yamaha customer support for further assistance. They will be able to provide you with more specific troubleshooting steps based on your particular keyboard model.

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.
