LED TVs these days come with a plethora of features and services like internet connectivity, recording live TV and more. All these features also increase the likelihood of malfunction or error in TV.
For example, a smart TV will face issues such as poor connection to the wifi or low signal on one platform compared to others. Similarly a TV that allows you to record live TV might face storage issues and interrupted recording etc.
Some of these errors are simple enough that you can solve them yourself while others might require expert help. In this article, we will discuss some of the common problems that an LED TV faces and what can you do to resolve them.
Stay till the end to find out if the problem faced by your TV is serious or just a temporary glitch.
Let us go through the problems and solutions one by one;
LED Tv Screen Goes Blank:
If your TV is switched on but the screen is black, blue or green. This is because your TV is not getting any signal. This might be due to loose wiring. Check behind your TV to see if all the wiring is attached properly. The problem could also be with the connection of the cable, satellite box or any other device your TV is connected with. Check to see if your satellite box is switched on.
Additionally, check the input of the TV, if you are on the wrong HDMI channel, then also the TV will go blank. If the problem persists then you could have two problems; the first one being that the video cable is damaged and the second one is that there is a glitch in your network provider i.e cable or satellite box. In both cases, you need to talk to a professional. You need to first check which problem you might have as both problems have different technical support that you need to call. To check;
- Try changing the HDMI to something else or if you are watching live TV try switching to streaming services on your TV, if the screen shows normal visuals then the problem lies with the network provider. If the problem persists then the issue lies with the video cable.
Horizontal Lines in LED TV:
Colorful horizontal lines on the screen might also result from a poor signal. This is common when you are watching something live like sports or award functions. If this happens only when you watch something live then it is not your TV’s problem but is a reception glitch. If this happens often, then you might want to switch to a higher input strength network like an HD set-top box.
Before switching to a higher strength set-top box, make sure you consult a specialist to rule out any other reasons that might be causing this glitch. This problem also occurs when the TV is an older model and the set-top box is a newer and latest model. This is because the TV has a lower input strength than the set-top box. You need to match the input strength of the TV with the set-top box.
The TV Has No Volume:
This could be due to internal or external speaker failures. You can check whether your external speakers are working or not and can easily figure out whether the problem lies in your internal or external speaker. Follow the instruction below to check the external speakers;
- Turn off the alternating current(AC) supply to your TV.
- Press the power button on the TV control panel(not on the remote control) for 10 seconds
- Now turn the AC power back on and press the power button once
- Now check the sound, to do this you can connect the TV to a set of speakers.
- If the speakers work perfectly then the problem lies in the internal audio system of the TV. If the speaker does not work then the problem lies with the audio IC
- You need to replace the audio IC to get back the sound. Both, to replace the audio IC and to correct the internal audio system, you need to call a specialist.
The Tv is Not Connecting To the Wifi:
Most newer modelled LED TVs also have Smart TV functions. And in order to function as a smart TV, it needs a smooth and uninterrupted supply to the wifi. If your TV is not connecting to the wifi then you need to first find out where the problem lies, is it the router or the TV? Connect your mobile to the wifi, if it is working smoothly then the router is not the issue. Now you can check behind the TV to see if the port which connects the wifi to the TV is not loose. If it is attached properly then you can factory reset the router.
You can also check the signal strength to ensure that your TV is getting a strong signal. If your TV is not getting the proper signal then you can use a wifi extender to increase the network coverage of your router. This will not only extend the network area but also make your network signal stronger which will help your TV get enough signal to work properly.
Grainy or Low Screen Quality:
This could be because of a few reasons. Let’s look at each one separately;
- Your display sharpness is too high, go to the settings and reduce the sharpness all the way to zero and see if the quality gets better. This is generally the case with new TVs as the settings are done to be most suitable for store lighting.
- Similarly, check the display setting to find out if your TV is in Vivid settings. If yes, then change it to the movie/cinema setting. This will bring down the contrast and make it more appealing to home lighting as opposed to store lighting.
- If you are facing display issues with some channels or platforms such as YouTube, then this might be because that particular channel or video is not 4K/HD supported. In this case, the bad display has nothing to do with your TV but the service provider.
- You can also ensure that if you have a 4K/HD TV then your set-top box is also 4K/HD compatible to get the best display quality.
We hope this article helped you understand the problem that your LED TV might be facing. If your TV is more than a couple of years old then you might want to get it checked with a technician to ensure that everything is functioning properly.
