📺 Common TV Errors & How to Fix Them — Tommie Kelly Euronics Guide

Your TV is one of the most important pieces of tech in your home — from movie nights to sport finals, it’s central to your entertainment. But sometimes your TV might not behave as expected: no picture, no sound, freezing screens, remote issues and more. Thankfully, many common problems can be fixed quickly with a bit of troubleshooting before calling in a technician.

Below we share the most common TV issues and what you can try at home to fix them — as well as professional repair support we offer at Tommie Kelly Euronics.

How to Approach TV Troubleshooting

Before trying fixes, it’s important to identify what the symptom actually is. Some issues are settings or connection only, while others may be hardware-related. Always start with the simplest solutions and work your way up.

According to manufacturer troubleshooting guides and repair resources:

  • Many issues can be resolved with basic resets and cable checks.
  • Frequently, problems lie not with the TV itself, but with external devices or inputs.
  1. TV Won’t Turn On

If your TV doesn’t power up:

  1. Check the power cable and outlet — make sure the plug is secure.
  2. Try a different wall socket or bypass a power strip.
  3. If there’s still no light, it may be a power supply issue that needs professional attention.

📌 Quick tip: Unplug it completely for 60 seconds, then plug it back in – this often clears minor power glitches.

  1. No Picture or Black Screen

If your TV turns on (standby light, sounds, menu visible) but the screen stays black:

  • Try a soft reset: unplug for ~60 seconds and plug back in.
  • Check HDMI and other cables — loose or damaged cables can block video signals.
  • If you can hear sound but can’t see a picture, it could be a backlight or T-Con board issue inside the TV.

Home tests to try:

  • Use the flashlight test against the screen — if you see a faint image, the backlight isn’t lighting up.

🔊 3. Picture But No Sound

Audio issues are surprisingly common and usually easier than they sound:

  • Check volume and mute settings
  • Make sure any connected speakers or sound systems are powered on and paired correctly
  • Try playing audio from another source or HDMI port

If internal speakers have stopped working, it might be a board or speaker fault — something our technicians can diagnose for you.

📡 4. Remote or Input Issues

Sometimes your TV is working, but the remote doesn’t respond or inputs like HDMI don’t switch:

  • Replace the remote batteries first
  • Confirm the correct input/source is selected
  • Disconnect external devices, then reconnect one at a time

Remote issues can also be due to infrared sensor blockage — clear sightlines help.

🔄 5. Software or Smart TV Glitches

Smart TVs can suffer from app freezes, slow menus or streaming problems. Often:

  • Updating the TV’s firmware solves bugs
  • Restarting the TV clears memory and glitches

🛠 When to Call a Professional

If:

  • You’ve tried basic steps and the problem persists
  • There are signs of internal hardware faults (no picture with sound, flickering, random restart)
  • Your TV has physical damage or persistent error states

❓ TV Troubleshooting FAQs

Q: My TV won’t power on but the standby light is lit — what should I do?
A: Try unplugging for ~60 seconds then restart. If still no response, it might be a power supply fault.

Q: There’s picture but no sound — is it the TV or something else?
A: Try another source or disconnect external audio. If the TV speakers still don’t work, it may need repair.

Q: Why does my TV image flicker or look distorted?
A: Loose HDMI cables or input signal issues are common, but persistent distortion may be a board or panel issue inside.

Q: The remote doesn’t work — what’s the first step?
A: Replace batteries and ensure nothing is blocking the TV’s infrared sensor.
