HDMI cables can fail, it is unusual however we have seen it. As mentioned, please first ensure your current HDMI cable is fully plugged in and connected. If it still will not connect, please get yourself a high quality (not necessarily expensive) HDMI cable, something like:
Try that does not work please unplug the TV from it's power source for 2-3 minutes and then re-plug in and also it is important that you keep the TV's firmware up-to-date. You will need to consult your TV's manual for instructions.
Then also unplug the Apple TV from its power source and re-boot it and keep TV OS up-to-date too.

You likely need to tell your TV to take input from the HDMI port to which the Apple TV box is connected. If you did that already, and you still are not getting any picture, then try the troubleshooting as listed on:

If this particular Apple TV box has been connected to a different TV before, then the ‘Check video resolution’ paragraph may provide the solution.
Try disconnecting the HDMI cord(s) on both sides, then reconnect. This should reset the HDMI connection.
Else restart all devices in the HDMI chain.
Else try a different HDMI cable.
This apple tv has been connected to this same tv before. There was no problem last time . I have turned on the tv and it says no signal. Nothing has changed . I feel maybe the HDMI cord is faulty?
