When it comes to digital outputs, numerous factors are involved. So the chances of interruptions are also high. A digital TV can lose signals frequently for many reasons including broken cables, damaged antennas, destitute wealthy connections, and secluded broadcasting towers.
Why Does Digital TV Keep Losing Signal
Imagine watching your favorite show and suddenly your TV keeps losing reception. You’ll feel irritated and frustrated at the same time, aren’t you? This is actually a very common problem and each person who owns a digital TV may have faced the issue. Here are the reasons behind it.
Acute Weather Conditions
Whenever the weather gets severe, there are high chances that you may not be satisfied watching the TV. It’s because the condition disrupts the signal from the transmission station.
Heavy rain, strong winds, or snowstorms can mess up the alignment of your cables. Also, tree debris or any other shattered structure overlapping the cables due to heavy weather conditions can disrupt the signal.
Wrong Signal Strength
Signal losses are often the result of poor reception strength. But it can be the result of too much reception strength as well. You have to troubleshoot this problem by checking the connection and the signal strength.
Presence of Obstacles Within Your Area
These interferences can be the electrical appliances or tall trees, sometimes buildings as well. If it comes in the way of your signal, it can disrupt it. Hence the total installation has to be accurately planned and calculated.
Another major reason for lost signals is damaged wires or cables. There can be issues in the hardware and the software as well. You can think that owning a terrestrial TV will save you from the damaged wires. But in reality, it is said that broadcasting signals over the air are not as trustworthy as the wires because interference occurs more in that case.
There are some other issues such as radio wave disturbance, static electricity, electromagnetic interference, overloaded TV transmitter, etc that results in lost signals.
An amplifier usually tries to clear up low strength channels’ frequencies. If some of your channels are out of signal and some are clear, this can be the result of the faulty amplifier.
How to Fix ‘No Signal’ Issues
If your TV suddenly starts losing signal, there are a few things you can do to solve the issue.
Examine The HDMI Cable
Wears and bends in the HDMI cable can cause the error. Don’t wiggle the connector. Just adjust the cable carefully. Try to straighten it out a little bit and see if that works. If that doesn’t work, take another HDMI cable and test with it. Also, check if your TV is on the correct HDMI source.
Check The Set-up Box
When you use an HD or SD box, the provider may deliver a new firmware and amend it in the background. It means new satellite settings have been transferred but the device may not be fully integrated with the modifications.
If you see the ‘no signal’ error just unplug the power cable and insert it after about 30 seconds again. Before that ensure if the TV is switched off or not. Also, pull out the viewing card. Give the box enough time to be cooled out. insert the card again properly and gently. This surprisingly solves the issue most of the time.
If your set-up box is connected through a coaxial cable. Check the cable and tighten it. it should be kept tight and strong. The coaxial F-connectors in your home may also need alternates. For replacement, you should call the cable company. You can’t replace it on your own.
HDCP Faults Check
High-Bandwidth Digital Content Protection (HDCP) error is not a common one. Almost all digital TVs of today are bound to be HDCP-compliant. However, if you’re trying to connect any offending device due to this error signal will be lost. To restore the connection just remove that additional device.
Other than these checks, your TV may need to be on a separate base channel as well. So, change the default settings sometimes to see if it works. You can reverse the sequence of the starting wire box and TV as well. However, if none of the above ways works, it’s better to call up for additional assistance.
How to Upgrade TV Antenna’s Signal
Most of us fail to be precisely concerned about the TV antenna. But it is very important to check on your antenna and keep some things in mind if you own a digital TV.
Remember you can use amplifiers to only passive and unamplified antennas. As mentioned before, too much reception is also possible and it often happens if you live very near the transmission tower. In this case, try to place the antenna as far as possible from the tower location in your house.
Except for this situation, place your antenna as high as possible and near the window. Usually, 30 feet from the ground level is considered the best height to place the antenna. Face it towards the broadcast tower whose signal you want to heighten.
Ensure your antenna is not blocked by the TV or hidden somewhere enclosed. Also, don’t forget to scan your channels whenever you’ll move the antenna or add or remove any amplifier.
Q: Does aluminum foil help in boosting antenna signals?
Ans: Yes. When you wrap an aluminum foil around your antenna, it will increase the surface area as well as the conductivity of it. Thus the signals that your TV is receiving will be boosted.
Q: Can Wifi interfere with the TV signal?
Ans: It’s not a common or likely case. However, the chances are there only if your TV antenna is placed right beside the wifi transmitter.
Q: Do I need a signal booster for my digital TV?
Ans: There are good reasons why digital antenna installation doesn’t come with a built-in amplifier. It creates a chance of too much reception. So unless your TV is having issues, there’s no need for a signal booster.
Q: What is a good signal?
Ans: A good signal is regarded to have a signal strength of 50%+ and a signal quality of 100%.
Nothing can be more unwanted than losing the signal while resting and exploring the channels. However, most of the time quick fixes solve the problem. It is always suggested to ground your device. It may not help in boosting the signal strength but it’s very important to secure the antenna. Hopefully, this article will help you to get rid of the irritation as soon as possible.
