How do i turn on smart tv mode with 1080p on hisense 55 inch without a remote

To play 1080p movie, just do it. No further move needed, cuz most smart TVs have no problem in playing back 1080p full hd videos. As for 4k Ultra hd video, you'd better downscale it to 1080p if you're not sure about your tv resolution.

There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
To do a factory reset, you should have a remote control.

This is probably very simple in the fact that your button is too sensitive. I have run into this with remotes a few times. Replace the remote and the problem should go away.

Hi,
here's the spec's for the 50" Model, it shows a headphone output and it will certainly be a 3.5 Jack: HISENSE LTDN50K321UWTS 50 inch 4K Ultra HD Smart LED TV Freeview

Some TV,s have a sound delay that you can change. Try getting into the settings of the TV with the remote and look up audio, go into settings and see if there is a delay parameter that you can change.

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
