How to Fix a Dead Key on a Yamaha PSR-280 Piano Keyboard

Introdução

If you need to replace a key on your Yamaha PSR-280, follow this guide. This fix deals with a contact pad. A contact pad is what the piano key hits that sends a signal to the speakers to make that certain note play. When the keyboard is not stored properly, dust can accumulate between the key and the contact pad making the key not work.

This is a good pictorial guide to how the keyboard works and how to service it, I used electronic switch cleaner {aerosol} on a cloth to clean the contacts and it was successful leaving all the keys working.
