Had a power outage now no longer even picks up the chromecast and when I change the tv to hdmi1 which it is plugged into it just keeps making a repeated sound every 3 or so seconds. No picture. Have tried to reset it I even did factory reset on my tv but nothing working
Thanks for reaching out and for being a step ahead of us. Let's sort this out.
A few questions: what type of Chromecast device do you have? What's the LED status on your Chromecast? How is the Chromecast receiving power? Did you use a power cable or USB port?
Give these steps a try:
Let me know how it goes.
