5 guides
TV has sound but no picture
Fix a TV with audio but a black screen: run the menu and flashlight tests to tell a failed backlight from a bad input, then check HDMI cables, ports, power resets, and picture settings.
TV says no signal
Fix a TV showing No Signal: the message proves the screen works, so the fault is the input, the source device, the HDMI handshake, or the cable. Includes the built-in cable tests.
TV has no sound
Fix a TV with no audio: run the built-in sound test to tell working speakers from a failed audio board, then check sound output routing, the headphone jack, per-input faults, and ARC or eARC soundbar setups.
TV remote not working
Fix a TV remote that stopped working: the TV’s own button tells you whether you’re fixing a remote or a television, then the phone camera test, a remote reset, and brand-specific re-pairing for Samsung Smart and LG Magic remotes.
TV won’t connect to Wi-Fi
Fix a TV that won’t join Wi-Fi: a phone hotspot proves whether the TV’s radio works, and the built-in network test names the failing step. Covers hidden and 5 GHz networks, password entry, DNS, signal strength and resets.
