Will receiving the text message affect the recording?

I will only talk about the three most likely aspects.

First of all, when you watch TV, you receive a certain frequency signal from TV.

This kind of interference will occur if the signal frequency of some other TV stations or radio stations is just close to the frequency of the TV program you watch.

Second, high-power electrical appliances will be used in nearby construction sites. The electromagnetic waves emitted by general electrical appliances are just received by TV and disturbed.

Third, it may be a problem with the TV itself, such as loose wires or a change in the modem inside the TV. You can judge this by reconnecting the wired interface or twisting the antenna. If it still exists, change the channel (it is best to judge that there is no construction in the nearby construction site)

Pay attention to electric shock in the above operation! !
