Skyworth 32 LCD TV has a sound when it is turned on, and the back is very bright, but it seems that there is nothing wrong.

First, it may be caused by the channel failure of TV video. Second, it may be because the TV signal is not received, which leads to the inability to appear images. Third, it may be that the TV screen is damaged and the image cannot be played. Fourth, it may be that the cable connecting the video inside the TV is broken. Generally speaking, the TV image is not displayed because there is a problem in connecting the power supply. You can check whether the connected power supply is normal. If there is no problem with the connection, try switching to another channel. Maybe the TV station is repairing, or connecting the TV and checking the network set-top box, so as to know if there is any problem with the power connection. It is also possible that there is something wrong with the hardware or display system of the TV set. In this case, you need to find a professional to repair the TV. Because there is something wrong with the TV motherboard, you can't repair it yourself. Blind maintenance will only damage the TV.
