My tv screen went blank but the sound is working perfectly well. Whenever I point a flashlight to it, i can see some movement and a little picture. I've switched off and on but it's still blank and the sound is still working. Please how can I fix this. It's a Logik television.

Your backlight is not functioning.
Give us the model off the TV, and we can determine if parts are available, and cost. Typically when the backlight stops working, the power supply for the back light has failed. There may also be one or more LED strips that are bad.
If you are handy with a screwdriver, this is possible to repair, again assuming parts are available. The power supply for a Logik LCD looks like this:

A part number or model of the TV will help a lot. It is probably the back lighting with can be the actual light or the board controlling the light. Thanks.
