No Signal Error from HDMI connections
HDMI connections on the back of the Samsung 40" LCD TV LN40B610A5FXZC are not working.
Try this Krystal:
1. Disconnect all HDMI sources from the inputs.
2. Unplug the power from TV/LCD for 10 minutes.
3. Plug the TV/LCD back in.
4. Connect the HDMI cable one device at a time.
5. Turn on the device (ex. PS3).
6. Repeat steps 4-5 for each HDMI port.
Let me know if this doesn't work and we will continue to troubleshoot your issue.
If you hold the exit button for 30 seconds (sometimes not that long), a box will come up asking if you want to set back to factory settings. This works on most Samsung TVs. I found it easier than the mute 182 thing.
If you need to do a Factory Mode reset on your TV you will need to power off the TV and then on your remote control press Mute 182 Power simultaneously. The TV will turn on with a secret menu and all you will have to do is press enter a few times and the TV will do a deep Factoy Mode Reset just like the TV came out of the box new! There is also a way to reset the HDMI ports in that menu as well.
only thing i can think of is restart and unplug for 10 min . because this can be easy fix with right steps
follow all the steps mention in this article Fix-Laptop is not connecting with TV using HDMI Port and i hope this will get you the help and fix the issue .
46" 2010 Samsung Smart TV.
In May 2017 after a power outage, all HDMI ports recognized there was something plugged in but couldn't read the signals from those boxes. So I did a factory reset listed in an earlier post. For my television this worked:
Power off television and unplugged for 10 minutes.
Disconnected the Roku and the Blu-Ray
Pressed Mute, 1, 8, 2, Power (on the remote -- in that order)
Television turned on with Factory Reset screen
Chose "Factory Reset"
The television automatically turned itself off.
Television turned on with the original set-up menu.
Plugged in each of the devices and HDMI ports worked as if it were new.
Ok I am writing this because I had some issue getting this to work, and felt extremely silly when I noticed that atleast some HDMI V.2.0, is one way. Which means that you have to plug them in the right way, source goes in the PC for example. Hope this helps some because I was ripping my hair out. :P
I had no luck with the reset and turning the TV off, I noticed an access panel at the back of the TV near to where my HDMI and cable plugin etc.
It had only one screw so I decided to see what it gave access too, so wearing rubber gloves (you never know) and unplugging the TV (of course) I decided to check inside.
I found several small circuit connectors hooked up to the interface circuit board, I made sure they where securely plugged into their respective sockets and made sure all the wires where seated nicely (pretty much by pushing them further in), I turned the TV back on and it worked like a charm I can now see my media PC again in glorious 1080p, so it was just a loose connection to the interface board, I taped the cables into position to make sure they don't move again with electrical tape, done :)
I have a Panasonic DVR connected to a Samsung UA55JU7500 Smart TV and experiencing long delay (up to 15 mins) for them to connect.
Solved the problem by setting the HDMI output of the Panasonic DVR to 1080i instead of 1080p .
The two now connect almost immediately.
Hpoe this helps
My configuration: Old 42"sumsung TV, Old Vaio Notebook with Nvidia GT8400 chip. I did everything from ound Ic's, one Signatel and one from Nvidia. During initial windows install the Sigmatel IC was enabled.
Disabling sigmatel the computer enebled automaticaly the Nvidia sound output.
That solved the problem
Ok I am at my wits end!
I have a Samsung 55" LCD that worked fine when the guy I bought it from showed it to me.
Some how during the drive home all the HDMI inputs stopped working and I can't get the VGA to work either. Only the component cables (red, white, yellow) are working.
I have tried all the solutions listed in this forum and even manually refreshed the software. NOTHING! Am I doomed to watch TV in non-HD until I can afford another TV? What are the chances that all 4 hdmi & vga blew at the same time?
Also, the hdmi inputs are recognizing the devices I have plugged in i.e Roku & chromecast just "no signal" error. Could it have something to do with HDMI-CEC? Which BTW I have no idea what it is.
PLEASE HELP! !! BEFORE I THROW A BRICK AT THIS THING!
Hi, same happened to me. What I found and did was disconnect everything from the tv. Then unplug the tv and wait 30 minutes. Then turn on with just one thing connected then power up tgat device. Then go to the next after tgat device is connected. Keep doing this until all is connected. Seems like the tv got confused with all connected and you must relearn it.
Our cable guy fixed ours…you need an hdmi 2 cable or 4DK cable for newer Samsung tvs
Well, I finally had success the next day, getting back to being able to view our regular cable programming channels. After live chatting with a samsung tech support guy for half hour late Friday night, and he saying I needed a samsung remote (which I had lost in a move two yrs ago), so I could use the "SOURCE" button to go between cable and HDMI, etc. So I called Best Buy the next morning (Saturday) to see if they had it they only told me they have "universal" remotes. I went there in the evening. Store guy said I had to get the programmable remote but then he showed me the buttons on the back of the samsung tv's in their store that work also as a "source" button! I had never seen a power button or any other button on the back or along the bottom of our tv, so I bought the $76 remote and on the way home, my spouse says "lets look at the user manual again to see if there are buttons somewhere we couldn't see. We figured out that the front of the tv at the bottom right there has nothing written there, just the sleek black frame around the flat screen, but we began pushing on the front in different places and, voila, the "source" choices showed up on the tv screen and then we had cable back again!! Going to return the remote we just bought and never opened. Such a relief. But why the Samsung tech support person didn't give me this info is what I couldn't understand and then I get the solution from a guy my age (61) at a Best Buy! Anyway, thought some of you might be interested in this info and update. Oh, and I then chatted with another samsung person and she said the guy I had previously chatted with needed additional training and she would tell her manager about him.
I have a US Smart TV and have been having power and video issues for awhile since I moved to Germany. Found out that the power here uses 50HZ instead of 60Hz. Anyway I have been unplugging my TV when it is not in use and it hasn't acted up since. I also made sure to update the systems firmware. Maybe this suggestion can fix some issues.
With Verizon I was getting no signal HDMI messages and eventually just unplugged everything and then untangled the wires so that they weren't touching anything especially each other. This seems to have solved the problem.
Select the source you want to fix (i.e hdmi) then goto info /menu/ mute/power through remote then try toggling the options until it says "success" or until you see the screen
I fixed my problem with hdmi out my motherboard ga ma 78gm us2h with built in graphic card ati radeon hd 3200 after 10 days i was no sleep by those steps:-
1- make Bois vga out on (D-sup / HDMI) or (vga /HDMI).
2-unplug all cables inside motherboard i mean power supply cables, data and sata, front panel cables and try with minimum cables inside motherboard may be something conflict with other like me
3- Try another HDMI cable
I hope it is works with you guys last thing i found that ccc version is not important because hdmi out work like vga (d-sup) thats what i noticed in final
I also had this problem. Brought a brand new Samsung 40" LED TV and tried connecting two different Samsung laptops. The screens would just go dark for a few minutes and then I'd get a "No Signal". By trial and error I found that the issue was with the cable not connecting to the laptop. If you push the cable all the way into the HDMI port on the laptop it won't work. Try to pull out the cable a little bit. Not sure if the cable is faulty or there is some issue with the laptop's ports. The cable in question came with an STB and works well with it.
I have a UE46C6000RK I have tried everything in this post and I am thinking it is the main board aka the T2 board, T-Con or main board as some people call it basically the board we’re all the HMDI connections live on? Has anyone had any luck replacing this? Or getting it repaired?
Right click on main screen, click on personalize, click on project to a second screen or change display settings.
This is most of the case with HDMI cable connections. I had a PC with NVIDIA GeForce 210 graphics card. It had a DVI, HDMI port. I connected it to a Sanyo (Panasonic) 49” Ultra HD Smart TV. I was using Windows 10 64 bit. But the signal simply refused to come in. I had the same error. But when I connected my Acer Laptop with Windows 7 32 bit, it was working perfectly. I also tried the Wireless display mode in Windows 10 but it didnt work.
Then I connected my desktop using Windows 7 64 bit OS. The HDMI handshake was successful, but the signal was hanging with bizzary time of in/out video coming in. So I felt that the graphics card also has a part in HDMI connection. My PC is a assembled one, while my laptop is a branded one.
Also there can be several reasons why HDMI AV connection may not work.
Hello guys I have a Samsung TV 32he4000 and I tried connecting my ps3 through hdmi port 2 since the hdmi port is bad but each time I press and hold for 5 seconds and a message pops up like mode not support I have done everything I was asked to do yet no solution… please help me I'm loosing it any other solution to fix this problem.
Switch on your receiver make sure your tv is switched off from the switch…let your receiver load and let it be done loading and start working (I suggest 5 miniutes at least)then switch on your tv(make sure all these while your HDMI cable is connected to both the tv and the receiver ,it should work because it worked for me..reply if it worked for you
I have a 2 year old Samsung Smart TV, connected to a receiver (thus I can have the TV sound on better speakers etc). The set top box connected via HDMI to the TV.
My problem is that I get the “No Cable Connected” message BUT I do hear the TV show via the receiver’s speakers which means that the TV does get the signal from the set top box.
I tried resetting the TV, STB etc - what am I missing?
It worked, but only on one port. The other 2 ports are not working…..suggestions??
WOW, years after this fix first posted and it still works! I was totally surprised. And I just saved mucho bucks to repair or replace my plasma 3D Samung tv. Thank you!
I have the same issue, I did all of this except take it apart and check the connections. Still not fixed. All my ports are not working except the ethernet.
I was having the same problem. I reset the TV to factory and no solution. I had 3 different HDMI Cables and not a single one worked. I had to go out and buy a new one. It seems that sometimes the cables burn out or the pins somehow get bent.
its just a problem of HDMI cable type.. HDMI 4K CABLE is the solution…
Hi, I am having a similar problem with my Samsung series 7 4K TV. However something is very strange.
The Samsung TV is recognizing with no issues HDMI cablesa from a nintendo and from an PC windows 10 (old PC with basic Graphic Card). directely connected to TVor via the Denon AV receiver there are no issues.
I have another PC( a GAME PC) with Windows 7 that I used to connect to the Denon or to other TVs or PC screens and I never had an issue. however….this time when I connect this PC, the Samsung is recognizing the HDMI( it knows something is connected) but the screen is showing NO SIGNAL and it states to turn on the device ( which it is ON). Also If I use the Denon , the TV still not Showing no signal for this PC. I plugged the different devised to all kind of ports to see if that wqas the problem but the only device I cannot get the video is the game PC
Another info the Game PC has a output( on Graphic Card EVGA Gforce GTX 260) DVI-I and input ( to the TV) HDMI, but this should not create an issue as we are talking of a video signal that should work. Never had a problem in other Smart TV’s.
Thank you for your help
ps= I also tried the 10 min options in previous posts
There are a number of issues that can cause this problem, but essentially it happens when the HDMI handshake fails. The handshake happens so that a connection between the source and your TV can be established, and a channel for the communication of you signal can form… ie you can see the picture from your film player, service provider or picture source.
In my experience this is most often cable related. For example! You may have had a HDMI 1.4 (or lower) cable which worked perfectly with your older HD 1080 TV but you’ve now got a UHD TV which requires an HDMI 2.0 compatible cable (higher bandwidth for the most part) but you’ve not changed the cable. Now it may even be that the old cable actually worked perfectly for ten minutes, an hour, or even a day, then suddenly it stopped working, and you think waahh it was working fine its not the cable, but in fact it is.
Without going in depth into why this happens, suffice it to say it just does. Minute variances in tolerance will cause the connection to fail when it falls below a tolerable level. The handshake is unsuccessful either initially, or when it is re-checked after channel has already been established (ie your in the middle of your favourite soap or newscast). Yes, it does this re-check to ensure compatibility and suitability is maintained for better transmission standards, capabilities and robustness.
Always remember, if something has changed the likelihood is that this change is the cause or a contributing factor to the problem, so don’t just dismiss the new setup as ‘fine and dandy’ because it worked for the ten minute test you did when you unboxed the new TV. If you have changed TV particularly if you’ve changed to a higher resolution 2160 device after having had your standard HD for a while then UPGRADE THE CABLE. If you had a the old TV for a few years at least you probably did not have an HDMI 2.0 cable to start with and you may not even have had an HDMI 1.4, it may have only been a 1.1
Generally it is best to start the TV first, then your Blu-ray player or other source device which will initiate the handshake. It Generally isn’t necessary to turn off a device for 15 minutes as suggested in some posts, as turning off merely restarts or repeats the handshake procedure. Going to the settings and removing the enhanced HDMI features may help as it removes some additional data for HDR etc (requires higher bandwidth) which your TV either may not support or may be causing the handshake process to fail. Some TVs can have different Name for this and indeed have different data sent ‘down the wire’ for additional services such as HDMI CEC which allows you to control other devices from a single remote. This can also cause problems in some circumstances, so all are best disabled at least initially till you establish the cause of the problem.
Also check your source. Some devices (older ones mostly) don’t initiate handshaking at all, (though it is mandatory in all US HDMI compatible equipment) and some have configurable options which may be preventing your handshake from succeeding. (my graphics card can disable HDCP a setting which my new 2160 TV refuses to accept though my prior HD TV didn’t seem to care about).
I know my post complicates matters somewhat, but all problems I have encountered with the “no signal’ error, regardless how stubborn, I’ve managed to solve. It does mean that there is no ‘one size fits all solution’ as some posts here imply, and sometimes if you’ve done the essentials (like the cable change) you may still need to be patient and try a few configuration combinations till you succeed. Also, avoid particularly long cables if you can help it, and if you have to go over 5 or 6 metres, make sure it is high quality cable.
Hope this helps
I have a samsung UHD 4K tv UE50NU7020 SMART WIFI.
