Screen is blank (TV)

Maybe there is an issue with the Cable TV provider, which is being resolved. Firstly, turn off the TV and turn it back on in two minutes. If the screen is still blank, contact their support and report the issue.

A slight nudge can sometimes disrupt the connection between the cables. Check the cables that connect the monitor and the computer by disconnecting and reconnecting them again.

TVs now have a bunch of sources that they can use to feed the display. You can connect your computer, your DVD player, etc. Check if the source being used is the one you need. For example, if you connected your computer to the TV via an HDMI port, make sure that the HDMI port is selected on the TV.

To check this, press the Source button on the TV remote control and cycle through all the options.

You may have reduced the brightness of your screen before and forgot to increase it. For instance, if your computer had to do some processing where the screen was not required (good to save energy).
