TV has sound but no picture? Check the menu, input, cables, and power reset

Sound with a black screen can come from the selected input, an external device, a loose or damaged cable, a picture-off setting, or an internal display fault.

Short answer: First stop for smoke, sparks, a burning odor, liquid damage, a cracked screen, unusual heat, or a damaged plug, cord, adapter, outlet, or One Connect cable. Otherwise, press Home, Menu, Settings, or Volume once. If the TV displays its own menu or volume bar, the screen can produce an image and the problem is more likely the selected source, external device, or cable. Confirm the correct input, make sure the source device is on, and—with everything powered off—reconnect one visible HDMI or manufacturer-supplied connection at a time. Check the manual for a Picture Off, Screen Off, or audio-only setting. Disconnect external devices and perform one model-approved power reset. If the TV’s own menu never appears, the picture flashes and disappears, the standby light blinks repeatedly, or the screen remains black after the safe checks, request qualified service. Never remove the rear cover, press on the panel, or test a backlight, power board, capacitor, or any energized circuit.

Why it matters

Samsung says that when a TV produces sound but shows a black screen, pressing Home or Menu helps separate a TV display problem from a wrong source or missing external-device signal. If the menu appears, Samsung recommends confirming the matching source, reconnecting undamaged cables while the equipment is off, and testing another device or input before requesting service. LG likewise uses the TV’s volume bar or on-screen “No Signal” message to distinguish a cable or external-device problem from a TV that needs professional diagnosis. A persistently blank screen can involve internal backlighting, display, control, or power components that store dangerous electrical energy and are not appropriate homeowner repairs. CPSC electrical-safety guidance treats damaged, loose, hot, or overloaded cords, plugs, and outlets as fire or shock hazards rather than troubleshooting opportunities.

Safe checks, step by step

1
Check for danger before touching the TV or connected equipment. Stop for smoke, sparks, popping, a burning-plastic or electrical odor, liquid near the screen or power connection, melted material, a cracked panel, loose glass, an unstable stand or mount, or a plug, cord, adapter, power strip, outlet, or One Connect cable that is hot, pinched, cut, burned, or visibly damaged. Do not unplug a wet or sparking connection; move away and call emergency services or a qualified electrician if necessary.
2
Confirm the exact symptom without moving the TV. Note whether sound comes from a live program, an app, or an external device; whether the screen glows faintly; whether a logo or picture appears briefly; and whether the standby light is steady or blinking. Press Home, Menu, Settings, or Volume once. If the TV’s own menu, volume bar, or “No Signal” message appears, the screen is working and the source path should be checked next.
3
Confirm the selected source and the connected device. Use the normal remote control to select the HDMI, antenna, live-TV, or app source actually being used, and verify that the cable box, streaming player, game console, or receiver is powered on. Test a built-in app or another known source if available. Do not repeatedly switch the TV on and off if it clicks, flashes, buzzes, or immediately shuts down.
4
Turn the TV and every external device off before handling signal cables. Inspect only visible, accessible HDMI and manufacturer-supplied connections for looseness, sharp bends, pinching, or damage. Reconnect one cable at a time at both ends, or test one known-compatible cable or another HDMI input if the manuals allow it. Never move a large or wall-mounted TV alone, force a connector, substitute an unapproved power or One Connect cable, or reach behind an unstable set.
5
If the TV menu is visible, review the exact model manual for Picture Off, Screen Off, Audio Only, energy-saving, brightness, or accessibility settings. Restore the normal picture mode only through the on-screen controls described by the manufacturer. Do not use a hidden service menu, factory reset the TV without first understanding what accounts and settings will be erased, or change unrelated calibration values.
6
Perform one safe reset if there are no hazard signs. Turn the TV and connected devices off, unplug the TV by holding the plug rather than pulling the cord, disconnect external HDMI and USB devices, and wait for the period specified by the owner’s manual. Reconnect the TV’s normal power connection directly, turn it on once, and check for its own menu before reconnecting devices individually. If the menu never appears or the black screen returns with every source disconnected, record the model, standby-light pattern, sounds, and test results for a technician.

Stop and call a professional if

There is smoke, sparking, popping, scorching, melted material, a burning-electrical odor, or unusual heat—disconnect power only if it is safe and call emergency services for active smoke or fire
Liquid entered the TV, adapter, power strip, outlet, or external connection, or the screen is cracked, glass is loose, or the TV or wall mount is unstable
A plug, cord, adapter, outlet, power strip, HDMI cable, or One Connect cable is cut, frayed, crushed, pinched, burned, buzzing, loose, discolored, or unusually hot
The TV’s own Home menu, settings, volume bar, logo, or “No Signal” message never appears even with external devices disconnected and after one model-approved reset
The picture flashes briefly and disappears, the standby light repeatedly blinks, the TV clicks or cycles, vertical lines or a large dark area appear, or the screen responds only intermittently
Diagnosis would require removing the rear cover, moving a large or wall-mounted TV without help, testing energized circuits, touching a power board or capacitor, replacing backlights or internal boards, bypassing protection, or pressing, heating, or disassembling the display panel
