I have tried to look up ways to troubleshoot the problem i have been having but have had no success. Every time i turn on the T.V, cable box, and receiver, it displays that it has no signal on HDMI 1. What could i do about this? if you need anymore info i will be happy to give it to you.
 
When components are connected via HDMI they each look to "handshake" with each other when turned on. In many systems the order in which they are turned on causes problems. If the no signal message is from the TV then I would try to leave the cable box and receiver on then turn on the TV. Also try other combinations. Try a different input on the TV. Does the problem happen if you connect the cable box directly to the TV with the same cable you use from the receiver?

I am having the exact same problem with this TV and a Bell Fibe box. I have replaced the PVR and tried all 3 HDMI ports with new cables, and the problem persists. It started recently and happens all the time now.

I am having the same issue with a Samsung J6300 (just bought on 7/1/2015) and Comcast HD box (not X1 Platform). When I use the Comcast remote to turn on the TV and Cable Box, i get the "HDMI signal weak..." message. If I turn the cable box off and on, the picture comes in. It worked fine until June 17th. Is it possible that new firmware was pushed to the cable box at that time? Does it have anything to do with the timing of when the cable box is turned on in relation to the TV being switched on? The workaround it to leave the cable box on all the time, but I'd still like to find the cause of the issue. Any ideas?

I too have a Samsung J6300 (the 40" model from Best Buy) I purchased back in July 2015, about 4 months ago.
Today all the HDMI ports stopped working, the main one HDMI I use with a cable DVR box.
After trying different HDMI devices, cables, etc and no change I happened to try unplugging the TV power cord for a few seconds and plugging it back in.
After that the HDMI devices worked again but only until I turned the TV off (standby mode) using the TV's remote control.
I can only get the HDMI ports to work again after unplugging the TV's power cord again each time after turning off the TV!
At least thats working as a temporary work around.

I did just read thru internet searches on this issue, that its recommended to try a hard reboot on the TV by leaving its power cord unplugged for 10+minutes while all the HDMI ports are unplugged completely. I'm trying that right now and see if it solves it completely. Another recommended solution is a full factory reset via the TV's service menu, but I'll hold off on that as a last resort since I assume that would erase all my custom settings which would take a long time to set backup manually - I would have to first be sure to write down all my custom settings for white balance, color space, etc. I had to do for each of the inputs.

I am having the exact same issue. It just started 2 days ago and I believe there was a firmware update right before. Basically, the TV works fine. However, when I turn it off and then later turn it back on, all the HDMI inputs say "no signal". The only way to fix it is to unplug the TV for 10-15seconds and then plug back in. Then everything works fine - until the next time the TV is shut off. I'm wondering if the new update had something to do with this issue since our issues seem to have started at exactly the same time.

I have the same issue. However, I did the "factory reset" and the HDMI/TV reset by unplugging for 10 minutes. The factory reset did nothing but wipe out my settings. The "Unplug for 10 minute" reset worked, but only for a few hours. My wife just called and said it was doing the same thing again. She left the house and left the tv on and when she returned, it had the "No Signal" message on it.

I have put in a service request. I have the 60J6300. Purchased on 06/22/2015. This is the first time I have ever had a problem with a Samsung tv. Undoubtedly, this is an issue they have with all their systems. When you search this online, there are a lot of people with this issue.

I contacted Samsung last night and they didn't say anything about a firmware update.. Where did you see that information? I know they did an update on Smarthub, but not the other..

If they did that, I am sure it has something to do with it. I had no issues with my television until last night.

Yep I tried the full factory reset today too but that didn't fix this issue. I had to re setup all my custom settings took a couple hours!
I also got this problem within the last two days like you all, so clearly now it must be a firmware issue to affect us at the same time,
I thought it was an HDMI hardware issue until you all confirmed the same issue at the same time.
I did have auto software updates enabled...

It looks to me like now when the tv goes into standby mode (power off with remote) the HDMI interface chips go into sleep mode and the bug is they aren't waking back up now when the tv comes out of standby. Full power off (unplug power cord) must reset the HDMI chips back to wake up but thats only until you turn off with the remote!

I thought I would need to try to get warranty service for a hardware failure but now it sounds like we need a fixed firmware update!

Yep.. Like you posted, something has changed since then. They have done something. I am going to let the service guy come out any way. I will let you know what happens.

I think I may call Samsung again as well.

You know, come to think about it, when I was on the Chat with Tech services, she said something about not being able to use the tv while doing a firmware update, but that I could use it during the Smarthub update. So undoubtedly, they did something.

Are you having to unplug all your devices (HDMI's) as well? Waiting 10 minutes, etc...?

Just spent 1.5 hours with samsung tech support and spoke to 3 different people. The first 2 seemed pretty clueless and wanted to do a factory reset which I did not agree to. Then they transferred me to a third tech who was going to use remote management to diagnose the TV's issue. When I finally got on the line with her, she told me that this is an issue that Samsung is aware of and they are working on a fix. She said she hoped there would be something in 24-48 hours but all seemed like generic bs so not too convinced that a fix will be forthcoming shortly. She then said that she could use remote management to do a factory reset. Since she indicated that she had been dealing with this problem, I asked her for how many cases did the factory reset resolve the issue - she said one. I then asked how many people did it did not work for - her answer "many." So I said let's hold off on the factory reset for now. So now just waiting and hoping that Samsung will come out with a software fix (the timing and number of complaints all really do point to an update bug) soon.

For now the temporary fix is that I have to unplug the television from the surge protector every time (I leave it unplugged for about 10 seconds - other devices can stay plugged in). Good luck to everybody else and if anybody has better luck with tech support (in terms of an actual solution), please post it.

Thanks for the reply. Did they say whether or not they did an update or what the problem is?
