My supersonic led tv has to run the auto channel scan, regardless of what i do. it wont do anything, but show me that message, even after i run it

Impossible to answer without 'Make and Model', but we can guess.

Scan for what? Scan for new channels?

How to Scan (or Rescan) For Channels on Your TV

How-To Geek https://www.howtogeek.com > how-to-scan-or-rescan-...
Jun 19, 2019 - Find and select the "Channel Scan" option in your TV's menu. This option is sometimes labeled "Rescan," "Tune," or "Auto-tune."

That's because there is no signal :>D

Unless you are using an outdoor aerial on the roof and the signal via a aerial cable, your signal is not provided by 'Channel Scan'. In most homes, your television comes from a Cable Box or a Satellite box. The signal from those is fed to the television via an HDMI cable. On your remote, find the Source Button and scroll though the HDMI socket inputs.

Please read all of this before you do anything since my last suggestion may be the place to start.

This means it "needs" to do this in order to find the OTA (over the air) TV channels which have recently changed. Go through the menu system & possibly Tools to find the auto channel scan and let it do that.

I don't know why it would ask you to do this unless you also have the TV attached to the Internet, then it would know it needs this new channel scan, but I have four TVs in the house and none of them told me they needed a new scan. I knew this because I keep track of what is going on with OTA TV channels.

So, let's assume you've done the scan again, you also say you don't know how to get it back to monitoring your camera.

Once the channel scan is done it may be happy and simply find your camera again. If not, your camera probably came with instructions on how to set it up in the first place, find those and find how how to attach it to the TV again.

If you've lost those instructions look up the make & model of the camera on the Internet to see if you can now download the pdf version of the user's manual and/or setup instructions.

LAST: You may want to try this first: Most remotes have a button called "Input" or "Source" look for that button. With the TV on & pointing it towards the TV press the remote "Source" button, look at all the input sources it has & go through them one at a time and then wait for something or nothing to come up. One of these sources may be your camera.

Set the TV to channel 3

If when You scan, and you don't get at least one channel, it will keep showing You this message! look at screen it will show new channels! if no new channels check to make sure your coax is hooked up good, also make sure you are using right setting if outside antenna, select antenna, if cable select cable for your source!

To Get free broadcasts you will need to 1) have an antenna and 2) run the Channel Scan or Auto-TUne program. Any antenna will work - Rabbit ears etc. Once connected you need to go to setup and run the channel scan - it will find the digital channels in your area and load them into the database. You can get an antenna at Radio Shack, Meijer, Kmart etc. any place they sell TV's. Like I said even the old Rabbit Ear antennas work fine for Digital TV.

I have run the auto scan many times and it never finds any channel. I found that you have to put it on the HDTV, PC, AUDIO channels in order to watch or connect anything on the TV. Try doing that.

yes file for repair as everything you would have to do to fix this means opening it. and likely voiding the warranty.
