Hisense tv worked yesterday with antenna reception, today it continulaly asks to run channel auto scan, which i have done repeatedly, antenna is not broke, tested it on another tv

This will be a main board issue, replace the board and the set will work like it's supposed to. I would take another TV and run a channel scan and be sure your antenna is picking up the channels before ordering a main

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.

Check if the antenna plug at back of tv is plugged in right. Otherwise it wont make good contact

If it is asking for zip code you have not told it to scan for over the air or antenna channels when it asks air or cable

Try using the TV's on-screen menu to manually add the channels or run another auto-scan. If done manually and the TV has no reception on these channels, the best you can do is to purchase a digital antenna which will provide more channels to a poor built-in antenna.

hello are you using a digital antenna, cable or satelite reception? you need to run your "set up" and scan for channels either automatically scan or manual scan, recomend a auto scan for all channels both digital and anolog, these tv will scan and save or store the channels but you need to run a channel scan first,
(even if your using a cable box or sat box)
back when we had the older anolog sets you could just plug it in and watch but with these new digital circuts need to scan and store the channels in before you can watch the broadcasts,, try that let me know what happens. hope this helps

have your tuner check for any cold solder on pins.

I notice that on mine, the positioning of the included tv antenna is very, very, very finicky. I also don't know how to "add" a new channel other than to hook it to the big house antenna and pick "re-scan" (or auto-scan or whatever it's called).

So I think your best bet is to pick a better antenna or know that even the tiniest fiddling with the antenna makes a diff. Sometimes, I even have the antenna horizontal (using the magnet) to get the good reception on a given channel. Seems like a hassle except that what should I expect from a tiny antenna....

check the setting the of your antenna poor reception will not lock the tuner to it.
