4k Chromecast causes TV to hum when displayed

Dual_Boot — Mon, 30 Dec 2024 12:17:44 GMT

Hi everyone I'm having a strange issue with my 4k CC, on my 75" 4k TV, when the device displays on the TV the is a low grade hum, no other device does this or causes it (AV amp, 4k BR player or laptop connected to the TV). It's ruining the experience of using it. Has anyone else experienced this and found a resolution. The TV is a Quantec which I've had no issues with with anything else, only the 4K CC.

Thanks 🙂
