So when I went to turn on my Theremin it started making this horrible noise along with the LCD screen to displaying anything. I've had my theremin for a couple of years and I've never had this happen. I haven't changed anything about my setup so just curious what's going on. If anyone has any helpful suggestions that would be great. I've also included a link to a video I made posted on the r/therimon subreddit to demonstrate the problem.
