@Pete2345: If the problem has persisted after using an alternate HDMI cable for the affected external devices, then please try powering off the TV, unplug it at the wall for 30 seconds, then plug it back in. Now, power on the external devices, then power on the TV and head to Home > Source. Let me know if this helps.
I have the same problem with my new QN90B
every morning have to unplug/plug in sky Q box 🤦🏻♂️ , not impressed.
does turning off input signal plus for the sky box take away from picture quality? If so that disappointing
Good to know, I’ll turn it off 🤞
I purchased my 65" QN90B TV along with a new TIVO 4K Edge in October 2022 and not long after started having problems getting "No Signal" when I turn on the TV set to the TIVO's HDMI. I would have to unplug the TIVO's power cord or HDMI cable and plug it in. It would detect it and I would then see the picture. The rest of the day when the tv was turned on it would be ok. Issue started happening every morning. I used a new 4k HDMI cable, switched to a different HDMI port and had the problem. I made calls to TIVO support and went through troubleshooting to the point I got them to send me another brand new replacement. Issue started happening with it. I then called Samsung support, went through their troubleshooting even doing a factory reset. They then referred it for a technician to come out. They made some system changes (not sure what). Worked for a few days and issue started occurring again. I called Samsung again and awaiting them to refer it to a technician again. I read this thread and disabled the Input Signal Plus for this HDMI port, but still had the problem. Again, unplugging the HDMI cable or powering off and then on the input source device then it starts working.
Shortly after this post, I stopped having the problem. Unfortunately, I don’t know what changed.
I am having the same problem with a Formuler Z11 box. It does not affect my Apple TV or (soon to go) cable box. Input Signal Plus was on (just playing around) and I turned it off and rebooted the TV. I still have the same problem. I really don't want to have to unplug my Z11 box every day!
