HDMI problems: No Signal. Check the external input or select another input using the INPUT buttons

Roots2018 — Tue, 07 Mar 2017 16:40:38 GMT

I couple of months ago, I upgraded and replaced my old perfectly working TV with a smart TV: Sony TV KD-55XD8577 bought as brand new. I plugged in Sky HD+ box into HDMI 1, Xbox One into HDMI 2 and external audio system into HDMI 4(ARC). Everything works perfectly well except that the HDMI continues to give me endless headaches. The problem is that I constantly receive the ‘No Signal. Check the external input or select another input using the INPUT buttons’ comment at the bottom right hand corner of the TV. It is annoying because I cannot watch anything using HDMI without first having to physically turn off TV, unplug and reconnect TV from the mains before it starts working again. The TV works fine for Netflix, YouTube or Amazon that do not require HDMI connection. The TV does recognize everything plugged into the HDMI ports but just does not work without disconnecting from the mains before watching something. I have made countless phone calls Sony customer support, I have tried everything but the issue remains unresolved. I have twice done factory resetting after updating and installing the latest software and firmware for the TV. I have tested the cables with the old TV and they worked perfectly fine, leaving me to suspect that the problem could be with Sony Bravia HDMI software. I asked Sony people to tell me if anyone has complained about this issue before but I might as well water a rock and expect it to answer. I have scoured the internet and online forums hoping to find something but still no luck. If anyone has any idea about how I can solve this problem (or are experiencing the same issue) please do let me know via the comments below, thanks.

Go and buy a bunch of cheapest HDMI cables, one will work always. I had the same with my AVR. And on the TV before with my SAT box. And cable that didn't work on previous TV with SAT box works perfectly on this one with AVR. HDMI is just a very poor standard because apparently every manufacturer can implement it in their own way.

Hi there

Try turning off 'Control for HDMI' or HDMI-CEC features to the Xbox and SkyHD+ and see if it helps with the issue.

Cheers

Hi there

Try going through the advanced steps in this thread:

https://community.sony.co.uk/t5/android-tv/hdmi-problems-troubleshooting-steps/td-p/2141941

Basically it involves breaking up your system and taking it back to its most basic setup. Then slowly add each device individually - eventually you will probably come to the problem device that is causing interference.

A good tip also is to separate the HDMI cables as far as possible away from the power and aerial cables - reducing the likelyhood of EM interference too.

Cheers

I am having the same issue on a 75 Sony Bravia 4k tv purchased last year (Nov 2016) with Verizon FIOS. When the TV is turned off for a while (4 hrs or more) I get the No Signal error. As soon as I reboot the Set top box, it will start working. Initially I thought the problem was the box from Verizon. I requested for a new box but got the same error message each morning. I connected the same box to another location with a Panasonic plasma TV and the problem is gone.

I am now convinced that the problem is with the Sony TV. Could be the Android software that keeps updating on my TV. I have another 55 Sony Bravia 4k TV that has the same exact problem.

I have a KD55XD8599 5/5/17, got it to replace my KDL46HX823. Today, No Input display? Checked all HDMI inputs, same response, No Input! Unplugged KD55, plugged in KDL46 & everything worked fine. Plugged back KD55, no Input on any HDMI. Replugged KDL46, everything works fine, must be a fault with the KD55. Have contacted Richer Sounds (Shop) awaiting response. 5 years warranty remaining.

I have had a KD55A1 for about a year now, connected to a Sky Q box. I have started to get this message recently and it is becoming more frequent. I need to turn everything off for 5 minutes and power up again to solve the problem each time. Very annoying. Going back to Curry's to see what they say.

Same issue here. I had the problem initially on the TV when I first purchased. Then it went away for almost 4-5 months! I was switching between HDMI inputs with no problem.

Now all of sudden I’m not able to use HDMI 2 unless I unplug everything, shutdown and wait. Even then it’s now hit or miss.

It’s frustrating because the TV does see there’s a device plugged in, it just won’t accept the signal.

Very similar issue here.

Had my Bravia about a year. Only has 2 HDMI inputs so I use HDMI ARC for my soundbar and then plug my Chromecast into that. HDMI 2 is my PS4 which works fine.

It's been somewhat tempremental for a long time with the chromecast, sometimes needing me to turn the TV off and on before picture shows instead of the "no signal" message but it's now constant. It lists the input as Chromecast so obviously recognises it's plugged in, but won't take the input from it.

Add to that Netflix won't load for the first few minutes after I turn on the TV either, seems to me there's probably been a dodgy firmware update which has nerfed some of the working functions.

I just purchased a Sony X930e TV and I Love the TV except I am having these exact same issues with using it as a display from my computer. I have swapped cables, displays and everything and it appears the problem is on the Sony TV side. 😞 I've used it for about a week and somedays it works amazingly well and then other days it will give me a huge headache by giving the "No signal. Check the..." message. I then can usually somehow get it to work after turning things off and on and plugging into multiple inputs etc. As mentioned by other people, it does show that it has an input, it just says that there is no signal when I know there is.

Any solutions would be greatly appreciated. Otherwise, I'll probably be returning it. 😞

I recently downloaded a new Sony update (to my two year old Bravia 4K OLED) and ever since have ben having the same problem: the tv doesn't recognize anything from any of the inputs. I don't even get a No signal message. I have tried different inputs, devices and HDMI cables, and comcast came out and upgraded my cable box, but still nothing. Also, a large percentage of the buttons on the remote stoped working. I can go "back", but I can't directly go "home". So perhaps the remote is part of the problem if the tv isn't getting the instruction to change inputs. Its like Sony decided to cut the cord with Comcast for me, as all my smart tv apps seems to work fine--just no inputs. All input welcome on this--Sony is being no help at all, despite their update causing the problem.

Sounds like I also have a similar issue.

I have a KD-49XF9005 connected to my soundbar. Sky Q to soundbar (arc) and TV to the other hdmi. I'm constantly losing signal and my TV is going blank. It's like the signal has disappeared between sky and TV because it's passing through the soundbar.

If I change the configuration and have TV to Sky Q and TV connected to Arc I get massive lip sync issues.

I'm getting frustrated with the setup and quality of these Sony products.

I have been having the same issue with an Apple TV 4K for some time already. Every other day, the BRAVIA wouldn't detect the input and show the mentioned message. The TV has to be rebooted in such case.

I have also tried several HDMI cables including Premium certified ones.

Long-pressing the power button.
