Chromecast with google tv not waking up screen

[brongracz]

Last January (2023, about a year now) after update of chromecast our device stopped waking up itself corectly. We have an "offline" LG screen. It always used to wake-up with the chromecast and then it stopped. It's for sure not screen update as I say it's offline: it doesn't update no wifi or other network on the screen. No matter the cec and remote settings its always the same after you power up the devices (the mains): they turn on normally. Then when you power down chromecast with it's remote the screen go to sleep with it. Then when you power chromecast again up with the remote the screen wakes up but says no signal and goes to sleep again and continues cycling like this but you never get the picture. Cycling continues until you power off be it mains or power button on chromecast remote. Screen has no IR so it only relies on signal from hdmi. It does wake up from say a laptop. Disabling cec features in chromecast  doesn't help. Playing with cec setting for the remote buttons also doesn't help. It seems like you've changed something to hdmi with that update last year. I find plenty of complaints online after that date with similar symptoms and no real solutions. And no turning off electricity for 15 minutes doesn't fix it. Turning TV after chromecast etc also not. Screen is LG 27UK600-w

Hi brongracz,

Thanks for posting here in the Google Nest Community. We’re sorry for the trouble, and this is not the experience that we wanted you to have. Yes, this was one of the recognized bugs, and this issue did come and go until an intended patch fix was sent and completed around October 2023, although there are still a few users reporting this. We tend to think that the previous patch file may have been overlapping or that there are missing files from the data library due to the consecutive patches. I suggest you do a full clean-up by performing a factory reset one last time, then setting it up from scratch to remove any corrupted files or data. If it persists after this, then let us know so we can forward this to our support team.

Thanks,

Kimy
