Recently picked up a firestick 4k and installed into the hdmi replacing a ps3. Wanted disney+. Anyhow audio works but video does not until numerous changing of inputs . Then itll stay on but flickering until a selection is made then it stays on.. any ideas whats happening or do i have a defective firestick. Thanks
