Hi CDCh, Thank you for sharing your review of the TU7000 Crystal UHD TV. We value your feedback regarding the included Sleep Timer and will share it with our teams. While the TV does not have a dedicated sleep timer button, you can still access this setting through the interface on the TV. Using your TV remote, navigate to Settings > General > System Manager > Time > Sleep Timer, and then select the amount of time you would like the TV to stay on before powering itself off. You can set the sleep timer up to 180 minutes, after which the TV will turn off.
