Signal Issues in Perth? What to Do When Your TV Is Pixelating

Author: TV King Perth

If your TV picture keeps breaking up, freezing, or flashing blocks on the screen, you’re not alone. Signal issues are one of the most common problems we see in Perth homes, especially across suburbs like Bibra Lake, Coogee, Spearwood, Hamilton Hill and Munster.

Many customers call us asking the same questions:
“My TV is pixelating, do I need a new antenna?”
“Do I need a new aerial or can this be fixed?”
“Can antennas be repaired or do they always need replacing?”

Let’s break it down.

Why Is My TV Pixelating?

Pixelation usually means your TV isn’t receiving a strong or stable signal. This can happen for a few reasons:

An aging or damaged antenna
Corroded cabling (very common in coastal suburbs)
Loose connections in the ceiling or wall
Antennas knocked out of alignment by wind or storms
Old antennas not designed for today’s digital signals

In suburbs close to the coast like Coogee and Munster, salt air can speed up antenna corrosion, while areas like Bibra Lake and Spearwood often experience cabling issues in older homes.

Do I Need a New Antenna?

Not always.

One of the biggest misconceptions is that pixelation automatically means a full replacement.

Sometimes the answer is no.

A professional antenna check allows us to determine whether the issue is:

A simple cable repair
A connection problem
A signal alignment issue
Or whether the antenna has reached the end of its lifespan

That’s why we always diagnose before recommending a replacement.

Do I Need a New Aerial or Can Antennas Be Fixed?

If you’re asking “do I need a new aerial?”, the honest answer is: it depends on the condition of your current setup.

Antenna set ups can often be fixed if:

The issue is caused by damaged cabling
Connections have loosened over time
The antenna has shifted position

However, replacement is usually the best option if:

The antenna is rusted or cracked
It’s more than 10–15 years old
Signal problems keep returning
You’ve lost multiple Free-to-Air channels

In coastal areas like Hamilton Hill and Coogee, replacing an old antenna with a modern, weather-resistant model often provides a long-term solution and prevents repeated call-outs.

Why Signal Issues Shouldn’t Be Ignored

Signal problems rarely fix themselves. In fact, they usually get worse over time.

Ignoring pixelation can lead to:

Complete signal loss
Missing channels
Interference during weather changes
Frustration every time you turn the TV on

With summer and Christmas approaching, now is the best time to get your antenna checked so you’re not dealing with issues when family and guests are over.
