One of the major complaints of Smart TV users is that ‘my smart TV makes a cracking noise’. To put it with more clarity, the smart TV makes cracking noise as is its parts are moving. This would happen more frequently when the TV is switched off. And, this behavior may have made you wonder if you got a faulty television. While cracking noise from a television is a common issue, it remains to be troubleshooted to see if it has a technical problem or a random and normalized TV behavior.
First try to figure out if the cracking noise comes out when the TV is off? Or, is the TV on. If you are hearing cracking noise when the TV is off or immediately after being switched-off, then this is a normal process that happens due to contract of TV parts. When you are watching TV, there is thermal expansion of TV components and when you switch it off, the components would cool off and contract. This process of contraction may generate cracking noise that is audible and irritating.
There is also a chance that you may hear popping noise from the TV during the evening or night as the temperature if lower during the evenings or the nights, thus making the metal chassis cooler than during the day time. Subsequent contraction may cause the popping noise to annoy you and your loved family members.
Also, if you hear persistent noise from a switched off television, do make sure that the TV’s rear screws are good and tight.

My Smart TV makes the Internet slow?
If you watch a lot of Netflix or use Amazon’s firestick, there are chances that you will encounter slow internet at some point of time. You will experience buffering while playing on-demand content. This would make you wonder if your Internet is good or if your Internet speed is sufficient for online streaming of content from these on-demand platforms.
The first thing to check is if your TV is wired to the Internet or if you are using a wireless connection between your Smart TV and the internet device. In most cases, you would be using an Internet connection over a wireless network between the TV and the model or internet gateway. Wifi data transfer speeds can never match the wired data speeds; this is a fact that one must keep in mind. When you connect your TV to the modem or router through a wireless network, you will need to thing about optimal distance between the TV and the internet device. If both devices are distant, you will experience slow data transfer between the Television and your Internet device. Higher the distance between your TV and the wifi gateway, lesser the data transfer speed.
If you are on Wifi, do find out if your TV and the Internet device support higher frequency such as the 5 Hz frequency. If you are capable of connecting the smart TV to the Internet device over 5 Hz, it will ensure a higher data transfer speed between the two connected devices. Otherwise, you would have to do good with a 2.4 Hz connection between your TV and the Internet device.
Another thing worth checking is to see if your TV and the Internet device are using the latest firmware. Both devices need to make use of the latest firmware so that the software on both devices is optimally configured at all times. You could easily check on the manufacturer’s website and try to patch your TV and the modem or router with the latest firmware patch. Remember, firmware upgrades are very useful in terms of device performance and security.
Besides these generic checks, it always makes sense to opt for higher priced and higher speed Internet connections from your service provider. It, almost always, ensures that your TV and other Internet capable devices are always geared up to make the most of on-demand content.
