Very few things are more frustrating than turning on your Digital Tv to watch your favorite show after a long day at school, work, or just during your relaxation time, only to get that “no signal” prompt. Now, let’s Find out more about Digital Tv Losing Signal.
You might be tempted to lose your cool and just start pulling random wires or fiddling with your cable box, but most times there is an easy fix.
How a Digital Tv Works
Before the advent of digital broadcasting, the world used analog TVs and while for the most part, they were functional, certain irreconcilable shortcomings eventually led the technology to become obsolete.
is the quality of the Signal declined the further away the receiver(user) was?
Digital TVs didn’t experience this as signals were transmitted in binary packets, worked with smaller bandwidths, and were able to transmit signals in HD format.
The effect was increased reach, better quality programming, and reduced interference among other advantages. In receiving signals for Digital Tv, users utilize antennas, digital cable, and satellite.
However, while it is a qualitative step up from the analog Tv, there are certain instances where a digital Tv would also experience signal interference hence losing the signal.
When this happens, you’re unable to access the channels at all, as it’ll only be showing a blank space with the “no signal” prompt. We will be diving into more details on what exactly causes Signal loss in digital TVs and ways they can be resolved personally and when to get a technician involved.
Causes of Signal Loss
1. Poor Weather: many times poor weather conditions cause signal interference. This is especially so when you’re using a satellite and receive signals through an antenna. The bad weather leads to interference causing sketchy video and audio reception.
2. Obstruction: the antennas that receive digital broadcast are usually placed in places of high elevation to allow line of sight between them and the broadcast towers, this is to prevent obstruction from things like buildings, trees, and elevated platforms. However, sometimes they get in the way and cause interference.
However, there are two types of obstructions, viable and non-visible. Examples of visible obstacles have been earlier mentioned, non-visible obstructions on the other hand arise out of radio frequency interference or reflection of the signals. Some causes of this obstruction are power lines, and cell towers amongst others.
3. Faulty/Damaged receivers: if the receiving equipment is damaged, it will most likely lead to a weakened or total lack of signal. This could be due to external factors, perhaps the weather, wear, and tear, etc. at other times it results from the purchase of substandard equipment, which is why there is a need to ensure that you buy receiving equipment that is in line with the standard specifications.
4. General Reception Outages: this is rarely the case- however, there are instances where the fault lies with the service provider, usually all subscribers are affected, and most likely, efforts are already being made to rectify the situation in which case all you can do is wait.
How to Fix a Signal Loss
1. Check Signal Strength: before doing anything else, there’s a need to check just how strong the signal you’re receiving is. This would give you an indication as to whether you’re receiving a weak connection or experiencing a total loss of signal.
In the case of the former, it might be a case of obstruction, weather problems, or improper connection. As for the latter, your cable is most likely disconnected, or the problem originated from the service provider. This helps to know where to look, or if you’ll require a technician to diagnose the problem.
2. Check your cable connection: sometimes the set-up- the box might be disconnected, or perhaps a bolt lose, you might have a frayed wire. These are issues that can be effortlessly resolved and might not need an expert technician.
3. Check for obstruction of your receiver: check the location of your receiver and if there are any visible obstructions in your vicinity, if there are, you might need to reposition your antenna, in case there is no noticeable obstacle you can check for equipment of instrument nearby that could cause possible interference with your receiver.
If this doesn’t work, you might need to invite a service technician or you can check if there are professionals who carry out interference inspections in your area.
4. Wait out the bad weather: If the signal loss is an outcome of interference from the weather, the best course of action is to wait it out until the weather clears. Most likely unless there’s damage to your receiver, the signal will automatically pick up after a while.
5. Reboot your Tv and set up the box: sometimes it might be a glitch or an issue with your settings that’s causing signal loss. Turn off the devices and restart to check the effect on your connection.
6. Lodging an interference complaint: most times digital Tv interference is the result of issues particular to the user in question and not from the broadcasting company itself. In this case, it can be easily fixed by checking your connection, or for complex problems, contact a technician. However, if you’ve considered all these and the issue still isn’t discovered, then there is a need to contact your service provider. They usually have a hotline for customers to lodge complaints.
Conclusion
Digital TV has proven to be a more efficient and effective means of broadcasting channels and programs that are popularly adopted, while they might also have a few kinks to work out, most times effortlessly remedied allowing you to go back to enjoying the best of the broadcasting world has to offer in a flash.
