I've had my tiny TV for a while and have had no issues whatsoever. Lately tho the there is a buzzing noise after a few minutes of play. This isn't the retro audio effect but a new and somewhat annoying sound. The buzzing gradually gets louder on its own and seems to peak after a few minutes - the volume up or down has no effect on the buzzing noise. If I have the volume down all the way the noise is very obvious and with the audio to the max the noise isn't as noticeable since the regular audio covers it. It doesn't appear to be any interference that I can't find. I've attached a recording of it. Thanks for any suggestions.
