My Sceptre TV randomly changes input sources

t's possible that the 5-year-old accidentally changed the input source on the Samsung TV, which is why you can't get the Fire Stick to work. Here are the steps you can follow to switch the input source back to the HDMI port where your Fire Stick is connected:

1. Turn on your Samsung TV and your Amazon Fire Stick.
2. Using your Samsung remote, press the "Input" button.
3. A list of input sources should appear on your screen. Use the arrow keys on your remote to select the HDMI port where your Fire Stick is connected. The HDMI port may be labeled as "HDMI 1," "HDMI 2," or something similar.
4. Press the "Enter" or "OK" button on your remote to select the HDMI input source.
5. Your TV should now switch to the HDMI input where your Fire Stick is connected, and you should see the Fire Stick's home screen on your TV.

If you're still having trouble, try unplugging the Fire Stick and plugging it back in to make sure it's properly connected. Also, make sure the TV and Fire Stick are both updated to their latest software versions.

Input source HDMI3 format is not recognized. Try selecting a different input source or connect a known good HDMI device to the HDMI3 input.

If you normally watch local broadcast TV from an antenna you need to change the "SOURCE" input to ANT (ANTENNA).

Have you tried checking the source/input? On the remote push the source or input button and try changing your source- hdmi 1, hdmi 2, wherever you have your cables hooked up, and make sure that particular source is powered up. On the tv's we've had, the outside antenna source is either called "video" or "tv". A quick clue would be if you push the input button and the little menu doesn't even appear. I'd say the screen is dead!

Assuming the DVD player has an HDMI port, run an HDMI cable from the DVD player to an available HDMI port on the TV. Let's say you have your TV service going to HDMI #1 on the TV, you can run the DVD to HDMI #2. When you want to watch a DVD, you must select the input/source on the TV remote to change it to HDMI 2(or whichever port you used). When ready to watch TV again, use the same button to change back to HDMI 1 (or whichever HDMI port you used for TV service). If you do not have an HDMI port on the DVD player, then you must use whatever type of connection it has and connect to the corresponding port(s) on your tv, Then follow same directions as above regarding choosing the input/source on the TV remote.

Check your buttons on the TV . Sounds like input or source button ( which ever one they call it ) is pushed in & stuck . Only way to make sure would be to disconnect it & see if it still changes inputs .

Is there a HMDI output on your Laptop or a VGA output. Some TV's have a DSUB input source that allows VGA depends on your laptop it could be HDMI if so TV should have an extraz HDMI input on the back and you change the source input on the TV to the HDMI 2 or HDMI 3 source depending on where you plugged in the P.C. . If HDMI you need to buy a HDMI cable.

The TV may not be on the correct source or input.
You can change the source by pressing the source or input on the TV or remote. VIDEO 1, 2,3. COMPONENT 1,2 OR HDMI 1 etc..

This sounds like a basic setup, so correct me if I made any wrong assumptions.

You have 2 "output" devices: a Roku and a cable box. Both have HDMI outputs.

You have 1 "input" device (your TV) that has 2 HDMI inputs available.

So, you need one HDMI cable to connect your cable box to your TV. Remember what HDMI port it's connected to - the back of your TV probably says "HDMI 1" and "HDMI 2" or similar. That's the "input name" of your TV.

Connect your Roku to your TV with another HDMI cable.

Now turn on your TV and use the remote to change between the inputs. Most remotes have a button that says INPUT or SOURCE (or sometimes a dumb little icon with no writing). If you press that it should change inputs. Usually, each time you push the button will cycle to the next input, so sometimes you have to hit it a bunch of times until the on screen menu shows the input you want. Most TVs will automatically switch to the selected input after a few seconds, so you don't have to push any buttons on the remote to tell the TV to change inputs.

If "at the same time", you meant actually watching both Roku movies and your cable at the same time, you are talking about a TV feature usually called "picture in picture". That should be possible, but will depend very much on your TV. I'd suggest checking your TV manual, or calling the company's 1-800 number and asking them to talk you through it.

My sceptre tv just started randomly changing through input modes, sometimes once or twice before stopping and sometimes it continues
