Why Your Digital TV Keeps Pixelating: Common Causes and Fixes in Melbourne

Blocky pictures, frozen frames and channels that vanish halfway through a show are annoying, and they rarely fix themselves. The good news is that most reception problems have a clear cause. Here is what the technicians at Auztech Security check first on a digital TV antenna call-out.

Common Causes of Pixelation

  • Weather and atmospheric conditions: reception can dip during storms or unusual conditions
  • Ageing or damaged antenna: sun, wind and years on the roof take their toll
  • Water in the cable or connectors: moisture quietly degrades the signal
  • Tree growth: new leaves can block a path that used to be clear
  • Too many splitters: each split weakens the signal to every TV
  • Faulty amplifier or wall plate: a failing part can cause drop-outs
  • Interference: some areas have interference from mobile networks and electronics

Quick Checks You Can Try

  1. Run a fresh channel scan on the TV
  2. Check that all cable connections are tight
  3. Try another TV or input to see if the fault follows the signal
  4. Remove any unnecessary splitter or extension cable

If the problem comes back, it's time for a proper test with a signal meter.

When to Call a Professional

Roof work is dangerous, and guessing at the problem wastes money. A licensed installer measures signal strength, checks cables and repositions or replaces the antenna as needed. Our digital TV antenna installation service includes testing every TV outlet before we leave.

Upgrade While We're There

Good reception depends on good cabling. If you're building or renovating, pre-wiring provides clean, hidden runs to every room.

They rank cameras by spec sheet. We install these systems in Melbourne homes every week, then get called back when something doesn’t work — which teaches you very different things about which cameras are actually good. This is a straight comparison of the four brands we install: Dahua , Hikvision , HiLook and Uniview . We stock all of them. We have no reason to push you toward one. First: The Thing Nobody Tells You The brand matters less than the install. A $2,000 camera system mounted at the wrong height, aimed at the wrong angle, with the recorder sitting in plain sight by the front door, is worse than an $800 system installed properly. The three things that actually determine whether your cameras identify an intruder: Height and angle. Cameras mounted too high see the top of a head. 2.5-3...
