We did try this. We found that out of five HDMI connections only 2 work, with one signal taking over another connection. My husband is going to try a factory reset. With the busy Easter weekend, we haven't tried this,yet. I will keep you informed if it works. Thanks for the quick reply. :)

Worked like a charm on Samsung led tv 40" thank you

Worked like a charm for me too. I was a little concerned as all of my HDMI ports stopped working, but a simple reset and it was all working again!

by

OMG I can't believe this actually worked!! Spent the last 5 hours trying to get our Samsung Series 7 LED TV hooked up to a new AV reciever (worked just fine on old reciever) and all HDMI ports were saying "no signal" to our PVR. The 10 minute trick worked a treat - unbeliveable.

by

Thank you! My 51" F8500 started having the same problem after working perfectly for a week. Unplugging fixed everything.

It worked once but now again it's the same problem.

It says No signal. Connecting my Xbox btw.

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.

Wished I had seen this earlier - a fast fix to a problem we had been attributing to the cable box

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.

Did it work? Cuz i'm trying to connect my led with desktop through hdmi port but no signals so far. :(

I've done a factory mode reset on customers TV's and it has fixed the problem. Sometimes it doesn't fix it though. I would also try a different HDMI cable that you know works and see if it works as well. You also should change the name of the HDMI source yoiur using on your TV for the computer to PC or PC/DVI for better resolution on the TV.

by

Mute 182 Power simultaneously?

Don't have enough fingers to do that.

Could you please rephrase that?>

by

press the buttons sequentially, not simultaneously.

by

Thanks Gary!

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 "Option"

Chose "Factory Reset"

The television automatically turned itself off.

Pressed "Power"

Television turned on with the original set-up menu.

Plugged in each of the devices and HDMI ports worked as if it were new.

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.

Good Luck!

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

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.

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

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.
