Why is there no picture only sound

Here are some troubleshooting steps you can take to help determine the actual issue with your TV. Let me know if you have any questions.

Software Troubleshooting:

• Hard Power Reset: Unplug TV, Hold physical power button on TV for 30 seconds, leave unplugged for 10 minutes, plug directly into a wall (not power strip), turn on.
  • If this works it was likely a firmware file corruption
• Try a Blind Reset: With the TV on, hold the reset button with a paperclip for 15-20 seconds (this is a pinhole near the HDMI ports), keep holding until you hear restart sounds.
  • This will force a firmware reset, a video reset, and an HDMI

Hardware Troubleshooting:

• Flashlight Test: Make the room very dark, turn the TV on, use your phone flashlight or a real flashlight at an angle against the screen and look very chiseler while pressing Home on the Roku remote.
  • You’re looking for faint menus, dim movement, shadows/images.
  • If you can see anything, the LCD panel is working but the backlight is likely failing - the most common issue on large TCL TVs
  • If the flashlight test shows an image, it’s might be worth repair if you can find someone with good pricing (LED strips: $40-$120 + Labor: $250-$500). DIY is possible but 75” panels are extremely fragile and removing LCD panels is risky.
  • If the issue is backlight, DIY repair or finding a repair shop can be an economical solution and could feasibly extend the life of the TV another 2-5 years.
• If there is no response to the Flashlight Test and there are the following symptoms: no image, strange flashes or lines before the screen went black, the TV cycles/restarts - then the LCD panel has failed and replacing the TV is the most economical option.
