Chromecast 4 caused Sony tv turning on and off repeatedly

Community Member

Chromecast worked for a few days but suddenly not working from yesterday. When I turn on Chromecast, my tv keeps turn on and off for about 3 times, tv then turned off and have red light blinking. I have to unplugged tv so that I can restart tv. I was wondering if it is related to HDMI-CEC, so I turned off Sony Bravia sync but it doesn't work. I also tried to use different HDMI port, changed the USB cable, changed adaptor..but all of this still doesn't fix the issue. Only unplugged chromcast can stop the restarting.

I've checked that my tv works fine and HDMI ports are working fine without chromecast.

Is there anything can help to solve the problems?

Hey there alexislulu,

Thank you for visiting the Chromecast Community! Since this thread hasn't had activity in a while, we're going to close it to keep content fresh. We hope you were able to get the help you need, but if you're still having issues, please make sure that the TV and Chromecast's firmware are up-to-date, then check if the same issue occurs on another TV. If the issue is isolated to the Sony TV, you may need to contact Sony support.

If the issue persists, feel free to create a new thread, and provide as many details as possible so that others can lend a hand. Hope this helps!

Best regards,
