Check that the TV is turned on. The power light should be illuminated.
Ensure all cables connecting the TV to power, antenna/cable, and external devices are firmly plugged in. Unplug and re-plug each cable.
Check the remote control battery level. Replace batteries if needed.
Try pressing the power button on the TV itself in case the remote is not working properly.
Make sure the correct TV input source is selected. Press the input or source button on the remote and select the input the TV is connected to.

Fixing Steps of Samsung TV Sound But No Picture

Adjust Picture Settings

If the basic steps above don’t restore the picture, the issue may be due to incorrect picture settings. Try adjusting these settings using the menus on the TV:

Increase the backlight/brightness setting. The picture may just be dimmed too much.
Adjust contrast, which controls white levels. Too little contrast can cause a blank screen.
Check that color and tint settings are at or near their halfway points.
Ensure sharpness is not set too high, which can cause a black screen.
Disable any energy-saving picture modes like Dynamic Contrast, which can interfere with picture display.
Reset picture settings to factory defaults in case of incorrect adjustments.

Faulty Connections and Devices

Check the connections from the TV to input sources like a cable box, streaming stick, Blu-ray player, or game console. Issues with cables, ports, or source devices can prevent a picture from displaying:

Try using different video cables that you know work properly. Cables may be faulty.
Bypass any AV receivers, switches, or wall connections between sources and the TV to isolate the issue.
Connect sources directly to the TV inputs using HDMI cables where possible for best signal quality.
Test different input ports on the TV itself in case one port has failed.
Power cycle source devices while connected to rule out device hangups.
Use alternate sources like a streaming stick or DVD player to help narrow down the source of the problem.
Update source devices with any new firmware. Incompatible versions can cause connectivity issues.

Check TV Settings

Dive into the TV system settings menus to verify the correct configurations needed to view the picture:

The TV tuner mode should match the TV signal – antenna or cable. Check tuner settings.
Input assignments for each port may be incorrect. Match up TV inputs to your sources.
Ensure HDMI ports are enabled if using those inputs. The main menu > System > HDMI may have HDMI disabled.
TV system software can get corrupted. A factory reset may resolve software glitches. Note you’ll lose all custom settings.
Enable CEC device control, allowing devices to communicate and control each other better.

Hardware Issues

With older TVs, hardware problems like failed capacitors on internal boards can result in sound but no picture. Some steps to check for hardware faults:

Examine boards for leaking, bulging, or burst capacitors. These are common fail points.
Inspect cables inside the TV for any that are loose or damaged. This can interrupt the signal.
Check for damaged ports where cables plug in. Bent or broken pins prevent connections.
Thermal issues may cause board failures. Ensure good ventilation and operating temperatures.
Previous repair attempts may have left hardware assembled incorrectly. Look for any obvious issues.
Professional repair may be needed in the case of extensive hardware failure beyond DIY fixes.

TV Tuner and Video Processor

The TV tuner, which handles antenna/cable signals, and the video processor, which generates the picture, can malfunction and need resetting to restore the picture:

Issues in the TV’s tuner may prevent display for antenna or cable sources. Power reset the tuner.
Factory reset options often reset tuner settings to default.
If faulty, the video processor board may need to be reseated or firmware updated.
Problem processor boards may need professional repair or replacement.

Backlight or Screen Failure

The backlight LEDs provide the illumination for the TV display. The LCD/LED screen itself can also suffer failure in some cases:

Restart the TV and try altering the backlight settings. Backlights may fail to activate.
LED backlights often use many zones or strips. One zone could have failed.
Screen polarizers, filters, and layers can stop functioning properly. Usually requires screen replacement.
Physical damage like cracks or dents on screens can block display. Physical repair or replacement is needed.
Professional technicians have specialized tools to diagnose backlight issues and screen failures.
