Hey guys,

So my neighbor just got a new TV but he paid for a Roku TV and didn't know about it. Since he has Verizon, we wanted to hook up the HDMI from the VZ box to the television. Instant TV right? WRONG.

I went through the setup, got it going but when selecting HDMI, there's a black screen. We tried the antenna but the picture is awful. What else is there to do?

His tenant is a VZ copper only guy and just recently switched/trained to fiber. He went to take a look at it and this is what happened (don't quote me on this because I didn't see it myself). The tenant put in RCA jack to the video and audio. Then the TV now has HD television?!??! WTF? I didn't understand but didn't see it myself.

Anyone else have this issue? Thanks

HDMI handshake issues? Was the Verizon box already powered on prior to turning on the Roku TV or setting the TV to the HDMI input? Maybe have your neighbor power everything off. Then, start the Roku TV completely, and set to the HDMI input. Finally, power on the Verizon box.

Hmm...we have a Toshiba Roku TV that had an inital issue with it not defaulting to the cable box and not remembering that you were last watching cable and staying there the next time you started the TV. Toshiba fixed that with fw update that allowed changing a setting so that it remembered where you were when you turned the TV off instead of defaulting whatever the default was.

Sorry, but probably not the same issue for Hisense.

Black screen on hdmi is usually the source being pre-set to a signal that is not compatible with the TV/Monitor. Usually - a forced setting (on the source) of 4K of some sort, going to an HDMI port on the TV that is not HDCP 2.2 compatible.

IF this is the case (not sure) - two possible ways to go:

- Hope that at least one of the hdmi ports on the TV are hdcp 2.2 compatible. Could be none of them is, could be just one of them is. So try plugging the hdmi cable in every hdmi port on the tv.

- If it works - while there is image, go to the cable's box menu and see if there are any settings to force the video signal to be auto-detect rather than 4K (if it's already on autodetect - tough luck, the box falsely detects the TV's port as being 4K, sends a 4K signal and nothing happens. I such is the case - manually set it to the next lower setting rather than autodetect).

- Or, reach that menu on the cable box while viewing the image through the RCA jacks.

- If none of the TV's ports work - again, get to the display menu on the cable box and force set it (NOT Autodetect) to something BELOW 4K).

It could also be something else, as usually when there's an hdcp 2.2 issue you'd get a warning message on the screen. But well. Could be old hdmi cables as well (not hdmi 2).

To add to the joys - hdmi 2 cables and hdcp 2.2 compatible cables are different things. You could have a hdmi 2 cable which is only compatible with hdcp 1.4 me think. I could be wrong.

Good luck

To be clear, the TV is the only thing that changed? Same FIOS box, same HDMI cable, everything known working, just swapped out TVs?

Correct, but the TV is a ROKU tv

so i run this setup at my gf’s place. she has a different brand tv but its roku and connected to verizon thru thru hdmi slot and once i select hdmi1 everything works fine.

i would try a different hdmi cable and check the settings on the verizon box (connect it to an old tv). also be sure its plugged in the correct hdmi port on the verizon box, some have a few.

That part doesn’t matter at all. They’ve just used Roku to make the TV a “smart” TV if he wants to use the apps. If he doesn’t want or need smart TV capabilities he can ignore it entirely, as it has nothing to do with the blank screen.

You didn’t share the model number, but I’m betting the TV’s included manual has a troubleshooting section. I’d see what it says. You may need to reboot or even do a reset on the FIOS box. Unless something got torn/pinched in the cable, if it worked before it should probably work now.

Sure thing.
Ditto on Deacon's advice. Being a Roku TV doesn't matter at all (other than Roku channels WILL be 4K when available without extra settings needed).

While you're on it - start here (from some Hisense Roku TV manual) :

"...Setting the HDMI® mode (4K models only):

On 4K (UHD) TVs, you can independently configure each HDMI® input to match the capabilities of the connected device.

From the Home screen menu, navigate to Settings > TV inputs, and then select an enabled HDMI® input.

Next, select HDMI mode and then select one of the following settings:

 Auto – Let the TV determine the best setting. Use this option unless your HDMI® device does not correctly communicate its HDMI® version compatibility.

 HDMI 1.4 – Configure the input for compatibility with HDMI® version 1.4, which supports a maximum refresh rate of 30 Hz at full UHD resolution. Most HDMI® devices will work correctly with the TV in this mode.

HDMI 2.0 – Configure the input for compatibility with HDMI® version 2.0, which supports a maximum refresh rate of 60 Hz at full UHD resolution. You must use this mode to view HDR content from the device connected to this HDMI® input. However, note that many older HDMI® devices do not work correctly when the TV’s HDMI® input is set to this mode...
"

Turns out you can set any hdmi port to any mode (which is good).
Set this to AUTO if it's set to anything else.

Could be the port that is being tried is set to force 4K - especially if it was a display unit somewhere (unlikely but you never know).

Also keep in mind that getting an image via hdmi will be only half the the job done. If both source device and TV are set to auto - they will be able to negociate an image that will be the lowest common denominator. If the hdmi is old/cheap for example.

Once you get an image, you'll have to go to the source box' settings (if there are any) that control the quality of the signal, and start trying higher and higher settings till it stops working again, then revert to the last working one. Then you'll have to figure out what is the bottleneck (I don't know what boxes Verizon has nowadays, I'd suspect they are 4K but hey. It's Verizon).

Sick of here...
Reset the tv to defaults using the menu on the TV.

This will wipe any hard forced 4K hdmi ports.
