TV Has Sound But No Picture — What Could Be Wrong?
TV Has Sound But No Picture — What Could Be Wrong? If your TV turns on and plays sound but shows no picture, you’re not alone. This is one of the most frequent issues TV owners face, especially with LED and Smart TVs. The good news is that most causes are repairable when diagnosed correctly. At Veetechno Electronics, our professional technicians in Hyderabad handle such problems daily. This guide explains why your TV might have sound but no picture, what checks you can safely do at home, and when it’s time to call an expert. Common Reasons Why Your TV Has Sound but No Picture 1. Backlight Failure LED and LCD TVs rely on backlights to illuminate the screen. If the backlight fails, you will hear the sound but see a dark screen. How to check: Turn on the TV in a dark room. Shine a flashlight on the screen from a close distance. If you can see a faint image, your backlight is defective. This issue usually occurs due to burnt LEDs or faulty inverter boards and should be repaired by a qualified technician. 2. Faulty T-CON Board The Timing Control (T-CON) board connects the TV’s main board and display panel. If it malfunctions, the display may go completely blank while the sound continues. Possible signs: No visible image White or grey screen Lines appearing before the screen goes black A T-CON board replacement typically resolves this issue. Our Hyderabad team handles this repair quickly with genuine parts. 3. Loose or Damaged Display Cables If the internal ribbon cables connecting the display are loose, the image won’t appear. This often happens due to physical impact or improper installation after a previous repair. Note: Avoid opening your TV yourself. The display assembly is delicate, and mishandling can permanently damage the panel. 4. Power Supply Board Problems The power supply board provides voltage to the backlight and other display components. A partial power failure can allow sound to play but stop the picture from appearing. Our technicians inspect the board for burnt capacitors, fuse issues, or voltage imbalance, then perform necessary repairs. 5. Display Panel Damage If your TV suffered a fall, screen pressure, or water exposure, the LED panel may be damaged. Unfortunately, a cracked or burnt-out display often requires a full panel replacement. At Veetechno Electronics, we help you identify whether a panel replacement or a board repair is more economical before proceeding. What You Can Safely Check at Home Before scheduling service, perform these safe checks: Ensure your HDMI or cable connection is tight. Try switching to another input (e.g., HDMI2 or AV). Restart your TV by unplugging it for one minute. Check for faint images using a flashlight test. If none of these steps work, it’s time to contact a trusted TV repair service in Hyderabad. When to Call a Professional Technician If you notice any of the following, call a service expert: TV screen is completely black, but sound works. Flashlight reveals faint images.
