Hey all. Clients been using this Roku Ultra since June. Now there’s no signal on her TV.

Back story:

The TV (can’t recall which , sorry) and Denon AVR (also can’t remember which but it’s one of the lower non-X series) were installed about 8 years ago with a Bell Expressview HD receiver.

In June I went back to install an Apple TV. Through the AVR the TV received no signal via the AVR. I forced resolutions. Powered up in order starting with the TV and working back. Switched inputs. CEC is all off. No signal. When I connected the Apple TV direct to the TV it worked fine. I called denon support. We did a factory reset and an update. Nothing.

Did some research. Apparently this can be a thing with some combinations of TV and denon AVR/Apple TV.

So I tried a Roku Ultra. Worked perfectly. Done.

She calls me today. Same thing with the Roku. No signal. Over the phone I had her power cycle the system. Unplug and plug in the Roku. Nothing. Plugged the Bell box into that cable. It works fine.

I think it’s a handshake issue. Not sure what to do next. It’s odd that it worked for a while and doesn’t now. Perhaps the Roku did an update and broke something?


The AVR is located about 20 ft from the TV in the basement rack. I have cat6 and conduit. I’d rather not enable ARC. If this is a handshake issue I could put the Rolu behind the TV and run an optical back. That would require some time spent reprogramming the remote. Not a huge deal but I’d rather it just worked where it is.

Are we still using HDMI splitters to solve issues like we did with cable boxes?

Any insight would be appreciated. I’m heading over on Wed but I’m not sure what to do. It should just work…. Buuut we all know how that goes.

Thanks.

Craig.

how long is the cable you are using? I've seen it where the short cables cause more trouble than a 6 footer with certain devices.

Interesting. The cable from the Roku to the AVR is a 3ft. I’ll add swap to a 6ft to the list.

that always our issues w rokus. i have many threads here with this issue. clock stretching still is an issue. a 1x2 switch should work, i forget where it goes before or after the roku. i feel handshakes and edid issue are becoming more common today.

we had one the other day. cable, yammy avr rxa2a, binary 540 extender to a sammy 8k from a few years ago. system has been in for 4 yrs. video stopped. changed extender, worked for 1 month, then same issue. i went box to tv direct worked fine, another cable box worked in same location, also tried another display woked

called yammy tech and we ended up changing a video setting in the receiver. i dont think it will change it, and i feel like i will be back but time will tell

edid is the death off us

A little more info.... you said you have a Cat6 ran, so can I assume an HDMI extender is being used for the 20ft run? Which brand & model?

Can I assume the Bell box can only output 1080p. That had better work or a lot of equipment needs to be replaced/upgraded.

There was a major update to Roku this last week or two (OS 12.5). So a good guess that some video settings got fudged and needs to be redone in the settings. Especially if it was left on auto detect (you should never leave Roku on auto detect).

The cat6 is there for future use. I mentioned it as I have an option to put it to use.

It’s a straight up regular HDMI.

Bell sat is 1080p I believe. It works fine.

I do have the Roku box set to auto. Shame. Shame. Alas it just worked when I plugged it in after a frustrating several hours of trouble shooting so I left it as is. I will remedy this.

Thanks!

Craig

I had an odd one a couple days ago, Blu-ray and dish receiver play fine into a Samsung television, straight 4 m HDMI cables for all.

The Roku sits behind the TV with a 1 m cable and it’s black screen. Unplug the HDMI plug it back in it will go all day. Switch to dish and back to Roku, black screen. tried a few different resolutions out of the Roku. I would say the TV is less than three years old now.

Randomly, I was switching the cables to different inputs of the Samsung and the Roku worked on the one input, I think it was a HDMI2, and I think it was marked MHL.
