Currently, the new generation of Smart TVs have integrated the function of using a mouse and keyboard to assist users in operating the TV more easily. However, during use sometimes Smart TV does not receive keyboard and mouse signal. So how to fix this situation, let's learn through this article with WebTech360 .

Because it is just one support feature attached, so during using it will generate some errors
Device not compatible with USB is also one of the reasons that the mouse and keyboard can not work on Smart TV. On the TV we usually will have 2 USB ports, so if this port does not work, you should try to plug in the other USB port, maybe that will fix the situation, or you can clean the USB port for clean the dirt before plugging it in again.

During the process of using the mouse or keyboard to control, if there is a feature that works on one TV but it does not work on another, it is completely not an error, but a possibility. device compatibility with the operating system. Each TV's operating system will have different compatibility.
Currently, the operating system of LG Smart TVs or Smart TVs TCL is doing quite well this job. Meanwhile, Samsung TVs or Sony TVs still do not support very well when they are only used for surfing the web.
After all the above methods but the mouse and keyboard still do not work, we should turn off the whole TV, unplug it or restore to factory settings of the TV to fix the error. If the situation still cannot be overcome, we should bring our TV to the genuine warranty center to be checked and advised by the technical staff.
