Hi Koriza, I’m having the exact same trouble with my tv not turning on. Could you also check my serial number for any resolutions? My S/N is: 65G2018CKH02754. There’s a bar code and the date May 23, 2020.
As I mentioned in an earlier post, I’ve tried everything, and there is no power button under, on or behind the tv. Nothing. Any thoughts much appreciated!
