Separate the display, playback app, source device, HDMI path, account, and network before resetting or replacing hardware.
AirPods connected but no sound? First select AirPods as the active audio output and raise the device volume. Then confirm both earbuds are charging, test each side, and re-pair or reset only if those basic checks fail.
If Netflix has sound but the screen is black, Netflix says the problem usually comes from the playback device or the video connection. Restart the device first; on TV-connected devices, test the HDMI cable, port, receiver path, and direct connection before reinstalling apps or resetting the whole device.
The Netflix app may fail because of a temporary service issue, stale app state, TV software, network trouble, account state, or an unsupported device version.
The Switch may be deeply discharged, using an incompatible adapter, have debris or damage in the USB-C port, be frozen, or have a battery or charging-circuit fault.
A wrong input, software freeze, backlight failure, loose source connection, or display hardware fault can leave audio working with a dark screen.
The TV is on an HDMI input but does not detect usable video. A wrong input, sleeping source, cable fault, port issue, resolution mismatch, receiver, or handshake problem can cause the message.
A weak power supply, storage problem, failed update, accessory conflict, or software corruption can keep Fire TV on its startup logo.
The phone and Chromecast may be on different networks, local-network permission may be blocked, isolation may be enabled, or the Chromecast may not be in setup mode.
Unstable bandwidth, Wi-Fi interference, congestion, device performance, VPN routing, or service-side trouble can interrupt Netflix playback even when a speed test looks acceptable.
The controller may be paired to another device, discharged, using a charge-only cable, or unable to complete Bluetooth pairing.
The console may output an unsupported resolution, fail the HDMI handshake, use a damaged cable or port, or start without completing normal video output.
Roku has joined the local wireless network, but the router, DNS path, captive portal, provider, or Roku network session is not reaching the internet.
The progress bar can move while audio is routed to another device, muted by the system or app mixer, controlled by Spotify Connect, or blocked by an audio driver or app state.
The YouTube TV app can fail because of stale app data, a TV software problem, account state, network trouble, incorrect time, or an unsupported platform version.
Video can remain black because of connection trouble, an app or browser rendering fault, DRM, an extension, hardware acceleration, casting state, or an unavailable video.
