If the power cable of your Toshiba TV is in good condition and is well connected to the power supply, there is a possibility that the HDMI cable that is attached to the TV is either faulty or is not connected well which is resulting in black screen.

This method may help you resolve the issue of the Toshiba TV black screen if the HDMI connection was interrupted. However, if you still have no luck, try replacing the HDMI cable to rule out the possibility of a malfunctioning cable.
