I just bought Samsung UHD TV SERIES7 no where manual shows how to set sleep timer

The sleep timer is accessed through the Menu under System > Time. You may need to set the TV time first which is in the same sub-menu area. For the sleep timer using the smart control, press Menu/123. Use the pointer button to steer to Menu then press the Pointer. Repeat this to select System. Select Time. Then select Sleep Timer and choose your time (up to three hours) when you want the TV to turn off. From the regular remote, press Menu. Use the arrow keys and press OK to move through the above menu steps. You can also do this from the Menu button on the Control Stick (joystick type control) on the back of the TV (lower left-hand side).

See page 126 (page 132 of the PDF) of the e-manual for the JU7000 series TVs for additional information or the section on setting the TV time. The e-manual is available online or through the TV. To read this manual, press the e-manual button on the regular remote. If you have the smart control, press Menu/123. Then select the e-manual from the on-screen remote. Alternatively, press Menu and then select Support > e-manual. The quick guide does not have the information on setting the timer. See https://www.samsung.com/uk/support/model/UE40JU7000TXXU/ under the Download Manual section. You may need to expand the list.

I hope this helps.
