What Can Cause Pictures to Breakup – Manual Tuning

Picture breaking up after Auto Tuning is carried out on the TV or PVR

This explanation will help those who are experiencing reception issues after carrying out “Auto Tune” to tune TV Channels on a TV or PVR.

On the Sunshine Coast most homes are able to receive signals from multiple transmitters.

When an Auto Tune is carried out on the TV, the TV tuner may select and lock onto a channel from a weaker transmitter tower for which the antenna is not aligned. As a result the TV will no longer lock on to any further signals for that particular channel. The symptom you may see is that 2 or 3 channels are OK and the others are breaking up.

Common signs to look for:

Intermittent glitches at times
Goes intermittently to “No Signal” at certain times of the day or night.
It may only effect some channels.

To overcome this issue a Manual Tune needs to be carried out.

The steps are as follows:

  • Unplug the antenna lead from the TV or PVR
  • Carry out an Auto Tune (this will wipe all stations from the TV’s memory)
  • Plug the antenna lead back into the TV or PVR
  • Determine, by looking at the direction of the antenna, which TV Transmitter Tower the antenna system is designed to pick up (see attached Map)
  • Go to the TV menu and find “Manual Tuning”
  • Using the table below, manually tune each channel for your specific TV Transmitter Tower tower. There are five channels in total.
  • If there are still problems after the manual tune in, it is safe to say that it may be a TV or antenna problem.

Call our office on 07 5479 1999, we can help get to the bottom of the issue.
