Weird Noise

[sanchitjain]

Hello!

My Pa300 is making a weird noise especially after booting up.

I could not find attach option, hence uploading the audio sample on Dropbox- https://www.dropbox.com/s/2ychhg3vla0vy ... e.mp4?dl=1

The sample is recorded via mobile kept over keyboard speaker and no other device was connected to it.

Please check and let me know your thoughts to fix it.

Regards,
Sanchit
