I have tried on two different TV's and it still says no signal and it's paring to my phone fine they are all on the same network and I've tried it on a Amazon fire tv and an Android TV the light is steady white I have tried rebooting unplugging and more I have read all the ways to fix the problem and none of them are working
Thanks for reaching out and for being a step ahead of us.
A few questions: is the Chromecast plugged directly into the TV? If not, where is it plugged into? Do you have an Audio-video Receiver (AVR) connected to their TV? Has the Chromecast ever worked with this TV? Is the black screen or no signal an intermittent issue? When does the black screen or no signal appear?
Try these steps and let me know how it goes:
