Hello, I just purchased a TCL roku tv, and I hooked it up to Verizon fios via an HDMI cable. When switching channels, there is a high pitch noise every time. Please help.
@Lv913 Thanks for reaching out!
We might suggest changing the HDMI cable, or HDMI input that the device is connected to. If that isn't doing the trick and you need more help with your Roku TV, please reach out to your Roku TV manufacturer.
