Common TV Aerial Problems and What They Mean

Before diving into fixes, let's identify what type of problem you're experiencing. Different symptoms point to different causes:

No Signal at All

TV shows "No Signal" or blank screen

Likely causes:

  • Disconnected or damaged cables
  • Aerial blown down or severely damaged
  • Transmitter fault in your area
  • TV input set incorrectly
Pixelated or Breaking Up

Picture freezes, pixelates, or has blocks

Likely causes:

  • Weak signal (aerial needs adjustment)
  • Damaged aerial elements
  • Corroded connections
  • Electrical interference
Works Sometimes, Not Others

Signal comes and goes, worse in bad weather

Likely causes:

  • Aerial pointing wrong direction
  • Loose connections
  • Water ingress in cables/connectors
  • Aerial at end of its lifespan
Lost Some Channels

Some channels work, others don't

Likely causes:

  • TV needs retuning
  • Transmitter frequency changes
  • Partial aerial damage
  • Amplifier issues

Step-by-Step Troubleshooting Guide

Follow these steps in order to diagnose your TV aerial problem. Many issues can be fixed without calling an engineer:

1Check All Cable Connections

Loose or damaged cables are the most common cause of aerial problems. Check these connection points:

  • TV aerial socket: Ensure the coaxial cable is firmly screwed into the back of your TV or Freeview box
  • Wall plate: Check the connection at the aerial wall socket - remove and reattach firmly
  • Amplifier (if you have one): Check power is on and cables are secure at both ends
  • Cable condition: Look for kinks, cuts, or damage to the cable itself

Tip: The centre pin of the coaxial connector should be straight and undamaged. Bent pins are a common problem.

2Retune Your TV

Retuning is the most effective fix for lost channels and can resolve many signal issues. The process varies by TV brand:

How to Retune:

  1. Press the Menu button on your remote
  2. Navigate to Settings or Setup
  3. Find Tuning, Channels, or Installation
  4. Select Auto Tune or Full Retune
  5. Wait for the scan to complete (usually 5-10 minutes)
  6. Save the channels when prompted

Important: Choose "Full Retune" or "First Time Installation" rather than "Update" to ensure all channels are found fresh.

3Check for Local Interference

Electrical interference from household devices can disrupt TV signals. Common culprits in Bedford homes include:

Known Interference Sources:

  • LED fairy lights and decorations
  • Cheap LED light bulbs
  • Phone chargers (especially cheap ones)
  • Electric blankets
  • Solar panel inverters
  • Central heating boilers

How to Test:

  • Turn off all unnecessary electronics
  • Unplug devices one at a time
  • Check if TV signal improves
  • Keep interfering device away from TV/cables
  • Replace cheap chargers with quality ones

Bedford-specific tip: We've seen many interference issues from solar panel installations in the area. If problems started after solar panels were fitted, this could be the cause.

4Visually Inspect Your Aerial

From ground level (never climb on your roof), look at your aerial and check for obvious problems:

What to Look For:

  • Direction: Is the aerial pointing the same way as neighbours' aerials? (Bedford area points towards Sandy Heath transmitter)
  • Damage: Are any elements (the horizontal bars) bent, broken, or missing?
  • Mounting: Is the aerial pole secure or wobbling/leaning?
  • Cable: Is the cable attached securely and running down safely?

Safety Warning: Never attempt to climb on your roof or access your aerial yourself. This is extremely dangerous. Professional aerial engineers have proper equipment and insurance for working at height.

5Test with Another Device

This helps determine if the problem is your TV or the aerial/cables:

  1. Connect a different TV or Freeview box to the same aerial point
  2. Retune the second device and check signal quality
  3. If the second device also has problems = aerial/cable fault
  4. If the second device works fine = original TV may be faulty

Tip: If you have multiple aerial points in your home, try connecting to a different room's aerial socket to test if all points are affected.

6Check for Transmitter Issues

Sometimes the problem isn't with your equipment at all. The Bedford area receives signal from Sandy Heath transmitter, which occasionally has planned maintenance or faults:

How to Check:

  • Visit the Freeview website and enter your postcode
  • Check if there are any reported transmitter problems in your area
  • Ask your neighbours if they're also experiencing problems

If there's a transmitter fault, you'll need to wait for it to be fixed. These are usually resolved within hours.

When to Call a Professional Aerial Engineer

If you've tried all the above steps and still have problems, it's time to call in the experts. You should also call immediately if:

Call an Engineer If:

  • Your aerial is visibly damaged, tilted, or fallen
  • Problems started after a storm or high winds
  • You've tried retuning multiple times without success
  • Your aerial is more than 15 years old
  • Multiple TVs in your home are affected
  • You need work done at height or on the roof

Frequently Asked Questions

Why is my TV aerial suddenly not working?

Common causes include storm damage to the aerial, loose cable connections, transmitter issues in your area, electrical interference, or the aerial naturally degrading over time. Try retuning your TV first, then check all cable connections.

Why am I getting no signal on my TV aerial?

No signal usually means the TV cannot receive any signal from the aerial. Check the coaxial cable is securely connected, try a manual retune, and visually inspect your aerial for damage. If problems persist, call a local aerial engineer.

TV aerial repairs in Bedford typically cost from £49 for simple fixes like cable replacement or realignment. More complex repairs or full aerial replacement range from £89-£189. We offer no call-out fee and free quotes.

Can I fix my TV aerial myself?

You can safely check cable connections, retune your TV, and move interfering devices. However, never climb on your roof to inspect or repair the aerial - this is dangerous and should only be done by professionals with proper equipment and insurance.
