Samsung smart tv--by mistake pressed source button, now no cable signal

No signal from the box supplying the signal, or someone pressed the Source button on the remote and you are accessing an HDMI Port that has no plug in it.

Hello rqromero2,

I found this on HP's website. I hope it helps

Picture quality problems (such as lines, fuzzy image, or wrong colors)Check the cables and connections:

1. Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors.
2. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
   Press the CH button to display a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
3. Make sure that the image quality issue is not coming from your source signal.
   For example: if the image quality issues occur while viewing TV, switch the source to a DVD player to see if the image quality problems go away.
   If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and .
   If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
4. Open OSD to adjust the picture:
   Press the Menu button to open the OSD. Select the Picture menu and adjust the image as needed. 
   If you cannot adjust the TV to fix the problem, reset the settings from the OSD to see if the problem goes away.
5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV. If the image quality problems still exists across all types of signal sources, the TV should be serviced.
   

If this dosent solve your problem, letus know and we will find another solution,

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.

TV Says NO SIGNAL - What To Check - How To Fix

https://removeandreplace.com > Cable & Satellite
Jan 14, 2016 - If it is just one TV that is showing the NO SIGNAL... -Be sure your TV is on the correct source or input as your CABLE or SAT BOX. -Press the TV ...

If the TV displays the menu or Smart Hub when you press the button on the remote - the TV is on, it's just displaying a black screen. Change the Source on the TV to another input. See the page on Samsung TV has No Picture for more troubleshooting steps.

Depending on the TV, there will be a Jog Controller or TV Control Stick that will allow you to access the TV menu and change the source. Use the control on the TV to select an option - toggle it left or right to see if anything appears on the TV.
If the control menu appears on the screen, the TV is on but not displaying any input. Check the connections or change the input source on the TV. If the controller button works on the TV, but not the remote, check the batteries in the remote control.

Unplug the TV from the power source and leave it for a minute or two. Reconnect the power cable directly to the wall rather than a surge protector. If the TV Standby light appears - the TV is receiving power. If the Standby light still doesn't appear, please get in touch to organise a service.

seems like he may have pressed the source or input key on the remote however you can do this both ways to get things back in order by pressing the source or input key and the tv should turn back to the source you want (if however no signal still try going into the tv's menu and look for a dish icon (samsung tvs) and change it from air to cable or if cable to air) if the source isnt cable choose HDMI for your set top box (dish network direct TV or spectrum box)

hit the source button again that is for your scat press down to 1 HD should get you back on.

Hey! We have a Samsung so it's prob not exactly like yours, but I thought it may be close enough. When our TV does this it's compliments of our 2.5 yr old.
........so on mine........
*Remote*
Hit [SOURCE]
choose - HDM1 satellite STB

*Side of the TV*
On mine you just press the side there's no "button"
It's SOURCE too. I just press it until the snow goes away.

Hope this some!! =)

Make sure your cable box is on and on a channel that you normally watch so that we know there is video being transmitted to the TV,then useing the remote that came with the TV press the button that is labeled " input" or " source" multiple times until you see a picture back on your TV screen. Good luck and Happy Holidays!

one thing you can do is reset the TV. You can go to menu, setting, then scroll down to the bottom and choose the reset all. The second thing is make sure that the source you have hooked up to the TV has good connection. Best way to test is to use a DVD player using HDMI or component cable.

I had exactly he same problem and it fixed by pressing several times the "source button"
