Grey dotted lines and other problems after F/W upgrade on Philips 65OLED854/12

Hi!

Not able to contact tech support for the next 2 days, so just checking in here if any one of you seen anything alike: https://www.youtube.com/watch?v=TcW1AVORRtQ

This happened after I updated to the latest update and now all things are haywire. This grey dot flickering (not static but dynamic), ambilight has turned off and the TV just feels slow and sluggish. I've tried "Reinstall TV" but it doesn't fix anything. Also plugged in/out the power cord few times.

Does anyone have any experience downgrading F/W on any recent Philips models or a way to do an even harder reset of it?

Try downgrading to the previous build, use the usb update function. Visit the support page on philips.com to download the zip file.

Update: if anyone else comes across this post, a service technician had to be sent out to fix it
