A problem has developed when my two TVs are tuned to the same channel. For example, if the living room TV is tuned to Channel 7 (ABC) and the den TV is tuned to Channel 9 (CBS), there is no problem. However, if I then change the den TV to Channel 7, the feed to both TVs is lost. Similarly, if I change the living room TV to Channel 9 when the den TV is already tuned to Channel 9, the feed to both TVs is lost.
It does not matter what channel the two TVs are tuned to -- if they are each tuned to the same channel, the feed to both TVs is lost. Does anyone know what the problem is?
Thanks -- I have already called Verizon, and they are planning to send out a technician on Monday, but I am hoping to avoid that.

It sounds like one of the 6 tuners in the VMS isn't working properly. The mini has no internal tuners, it tells the VMS what to send it, then the VMS uses one of its tuners to send the correct station. I would get Verizon to send you a New VMS box and see if the problem goes away. You shouldn't have to watch an SD station on one set while watching an HD version on another.

What kind of boxes from Verizon are you using? Did you check all coax connections? Did you try replacing the splitter? Have you tried removing power to all the boxes then plugging them in one at a time?
I have used Arris boxes since July 2019, when I became a Fios customer. This problem began only two weeks ago.
Whoops, I did not initially see the rest of the post. The coax connections are okay, but I have not replaced the splitter nor tried turning on the boxes one at a time. What would be the reason doing the latter two things would resolve the problem? I'm trying to understand the basic problem here. Thanks.
Unplugging all of the STBs, waiting for a few moments and then plugging them back in is like a soft reset. Something may have gotten messed up, and a reset might clear the trouble.
If I were to reset all of the STBs in our house, I would power down the minis first and the VMS (the main unit) last....and then plug them back in in reverse order...but that is just me.
Coaxial cable splitters can go bad. While not a common occurrence, it does happen. Also, Verizon uses splitters that are MoCA 2.0 compatible. Older splitters may not be, and those should be replaced.
Open/unterminated ports on splitters are bad news. If there are any, purchasing a few 75 ohm termination plugs and using them to fill the open ports is recommended.
I also like to suggest inspecting coaxial cable terminations. Often coaxial cables are found to be poorly prepped before connectors are applied. Some DiY videos on YouTube that show how to terminate coaxial cable should be renamed how NOT to terminate coaxial cable.
Because the television service has operated properly for years, that would discount a cable problem, but it is still good to inspect once in a blue moon...even to check for loose connections.
Thanks, dexman. By the way, this is actually the same problem I reported a few days ago about the Fox News Channel going out, but I did not understand then that the problem was caused by the two TVs being tuned to the same channel at the same time. It seems to me as if one of the STBs is blocking the other STB from using a channel when the first STB is using that channel.
To have both STBs lock up like that when set to the same channel just seems so weird. 🤔
If you tune one box to the SD channel, and the other to the HD channel, do they crash again? 🤔
No, and so I guess the simple solution is to use the regular channel on one TV and the HD channel on the other TV. Of course, some channels do not have an HD version, but I can live with that.
Thanks again for your assistance.
I'm curious as to what the technician finds. Please post what the solution is. 🙂
I cancelled today's service appointment because there is no problem with my Fios setup as long as each of my two TVs are not tuned to the same channel at the same time. It's a weird technical problem, but one I can live with. However, if anyone here figures out how it came about, I would appreciate hearing what the solution is. Thanks for offering various suggestions.
It could be a problem with one of the STBs...most likely the main unit (the VMS). 🤔
The only way to know for sure would be to first try a factory reset of all of the STBs, and if that doesn't clear the trouble, replace one or all of the STBs. 🤔
Thanks for your further response. If one of the STBs is the problem, shouldn't Verizon be able to detect that remotely?
Unlike the ONTs and routers, I'm not aware of any error or alarm logging capabilities of the Arris STBs. They may exist, but that would be a guess on my part.
Usually it is trial & error that works. 🙂
Thanks for those educational comments. Verizon did try a number of remote fixes and none worked.
