Nothing could be more relaxing than sitting in front of your TV watching your favourite movie or shows at the end of a tiring day at work. But this is all ruined if your TV signals aren’t reliable, and you keep seeing blurred, distorted images. It becomes worse when it can’t pick up any signal at all.
Problems with TV antennas are common in Australia. When issues like these occur, calling a professional antenna service company is your best solution. But before that, you need to do the following:
- Check if the cable or satellite menu is visible on your screen. If you see it, this means that your TV is working optimally; otherwise, the problem is with your TV.
- Make sure that the antenna is properly mounted on a pole that goes down the ground.
Local Tasmania TV antenna installation experts have the right experience and tools to make sure that your antenna is configured so your television receives the best reception possible.
But in case you are faced with TV reception problems, here are three issues in troubleshooting TV reception, their possible causes and solutions:
1. TV is not receiving any signal
After the antenna has been installed, change the TV input to “antenna” before running a channel scan. You must be receiving some local channels already. If not, here are possible causes:
The signal is lost in the coaxial cable distribution
Regularly check for loose cable fittings and corrosion. Using a splitter can weaken signal strength as well. So you must disconnect the splitter and connect the cable directly to the TV and run a channel scan. An improved reception implies that a distribution amplifier is the best solution.
An unclear line of sight to the broadcast towers
When buildings and geographic features like trees and hills are in between the antenna and the broadcast towers, the signal might not reach your TV antenna.
The reception can be increased by placing the antenna in a higher location. Investing in pruning or hedging services to remove tree branches that obstruct the line of sight can also be a great solution. The key here is to achieve an unobstructed line of sight towards the broadcast towers.
Long coaxial cable from the tuner to the antenna
About 1/3 of the signal can be lost if the length of the cable is more than 30 metres. A preamplifier is required if you need to use a long cable or a splitter.
2. Picture is unclear
The channel scan or auto program procedure was done incorrectly
Make sure that the TV input or source is set to “air”, “TV”, and “broadcast” instead of “cable”. After verifying this, scan for channels. Remember that every television is unique and various brands have different procedures. To make sure that proper steps are followed, check the TV manual or perhaps contact the manufacturer.
TV does not have a built-in ATSC digital tuner
Digital antennas do not show fuzz or snow on your TV. Oftentimes, this problem is the result of a TV that doesn’t have a built-in ATSC tuner, especially those purchased before the year 2007.
To find out if your TV has this tuner, check the manual or call the manufacturer. If your TV does not have one, you must buy a converter box or an external receiver so your television can receive HDTV broadcasts.
3. TV is receiving channels except for one
The transmitter for that channel may be at a lower elevation or behind another broadcast tower
Obstruction by other towers or lower elevation can cause problems with the line of sight. Consider changing the elevation or location of the antenna to improve the signal strength.
The station broadcasts on a different frequency
Most televisions today transmit on UHF frequency while some use VHF. So it is crucial for you to use an antenna that is optimized to receive both VHF and UHF frequencies.
If your TV antenna is giving you unreliable reception, the best thing you can do is to call TV antenna & aerial specialists as they provide reliable and quick antenna servicing. They will perform a full assessment as well as diagnose reception problems using specialised equipment. With their help, you’ll definitely be sitting comfortably on your couch watching your favourite shows and movies in no time!
