The Hisense EN3G39 is the remote control for the 55N8700UW, 65N8700UWG, and other TVs. I have never seen an option for removing the standby mode from any TV without a change to the firmware. The TV will always return to the standby mode when power is returned. The type of firmware change that you want will not be available from the TV manufacturer. The smart plug is great for reducing your power bill when you aren't watching TV. It won't avoid the turn on step. I wish that I had better news for you. Cindy Wells (I wouldn't recommend trusting a third-party firmware if one exists or was created for your TV. That would void any warranty and could cause problems with the TV.)

THINK REPAIR SHOP LOCALLY

bad horizonal hold board

First make sure that you have the antenna connected to the RF jack. Go to the Home screen of the TV and select the Antenna TV tile on the right hand side of the screen. (If you acquired the TV from a previous owner, they could have hidden this tile. See the steps preceded by Otherwise.) If this is the first time you scanned for channels, just follow the onscreen prompts (including setting your time zone). Otherwise, go to Settings (below Home in the left column on the home screen) > TV Inputs > Antenna TV > Scan again for Channels > Start finding channels. Use the arrow keys to navigate the menus/tiles and press OK to enter. To save, make sure to select Done and press OK. The manual for the Hisense Roku TV (2019), 32HF4030F is available here: https://www.hisense-usa.com/support/models/32H4030F_hd-hisense-roku-tv-2019 . The current link to the manual is https://assets.hisense-usa.com/assets/ProductDownloads/88/c8c9a74079/Roku-User-Manual.pdf . The section for setting up TV channels starts on page 39 of the manual. See the section starting on page 10 for information on using the remote or TV front panel buttons in the menu. I hope this helps. Cindy Wells

Lightning ruins everything electronic, even things you cant see. It is best to replace the whole unit. You could find the part that is bad and replace it but then there will be something else and it is a rabbit hole. By the time you are done, you will have spent more time and money than you would have just buying the whole set.
