I have bought a replacement adaptor but when I turn it on there’s just a continuous loop of a sound coming from the speakers and nothing works. Any help would be much appreciated

@justmustard this does not sound like a power adapter issue but just for completion sake let us know why you replaced the adapter. Your Yamaha PSR-175 needs a Yamaha PA-3C or PA-3B AC (12V DC 700mA)power adapter. Make sure you remove any old batteries and check the contacts on those.
It is possible that you have a stuck key/bad keyboard matrix or have an issue with your keyboard circuit board. I’d disassemble the keyboard and take a look at the PCB’s first to check for any obvious damage.
Post some images of those with your question so that we can see what you see. Aggiungere immagini ad una domanda
