Hdtv Ultimate 4.0 Not Working

[Marquez Feliciano]

Onetime the ROKU letters were recognized (letters jumping up and down) and then the screen went blank (no program), but I could hear the remote signal sound when hitting any of the remote buttons. Still no screen display though. The remote seemed to sync up with the unit very quickly that time, other times it never syncs.

It sounds like your TV isn't communicating correctly with the Roku about its supported resolutions. The HDMI protocol has what is called a handshake, and the two devices are supposed to understand and agree what each device supports. It sounds like the TV is sending incorrect data to the Roku, most likely that it is capable of 1080p. Unfortunately, there are some of those early HDTVs that had issues like this.

You might be able to press the remote buttons in the correct sequence to manually set the TV to 720p, but I don't have one of those players so can't say for certain what the sequence might be. You could take the Roku to a different TV that it works on and manually set it on 720p. In theory it should remain in 720p when you connect it back to the JVC.

I was able to set the resolution on the ROKU to 720p by hooking it up to my newer smart tv. I then went and connected to my old hdtv. With most attempts the old tv didn't even recognize the ROKU input (thur hdmi cable). But on a few occasions my old tv did connect to the ROKU and my hopes were raised high, success finally, I thought.

Then after moving around through the ROKU menu the connection dropped - "no signal detected." I'm going to try switching the ROKU to 1080i and see if my old tv would recognize and keep this resolution. (At this point I'd accept 480p if it is available on ROKU.)

No Roku player supports 1080i, which is usually where the problem occurs with older sets. The handshake they offer misidentifies the set as 1080, so Roku sends a 1080p (progressive) signal. But the TV will only accept a 1080i (interlaced) signal, so you get that error. Unfortunately, there's little that can be done with TVs that misidentify themselves.

As to why the Roku won't now link to the other TV, I have no good answer. You could try a different HDMI cable, or a different port on the TV. Make sure everything is turned off (TV and Roku) before making the connection.

No, there's no way to change the resolution at the TV itself. The display has a native resolution, and that's all it knows. The internal electronics will convert the incoming signal to the display resolution, within the limits of its hardware and programming.

I was finally able to get my in-laws TV working with an HDMI to Component Converter that also has a scaler. They have an ancient Mitsubishi Rear Projection HDTV that has no HDMI ports and only supports either 480p or 1080i and no 720p all. Make sure the converter/scaler device you get supports 1080i, some don't. I finally got it working on the third product. The scaler is critical too because it's the only way to force a specific resolution. The brand of the converter is EASYCEL and it was $45.

There's no such device with today's media streaming products. HDTVs that don't support either 720p or 1080p have vanished from the market. It's next to impossible to even find Blu Ray players with analog outputs anymore. DVD players are about it, and even some of them use HDMI as well. They've all moved to HDMI for the simplified connection.

I have an HDMI connection on one end and composite on the other end. This is a cable from my playstation 3. With the remote, I can set my resolution on the tv to 720. I am wondering if that would work with Roku as well. Thanks for your reply's.

My arc just stopped sending audio from my Sony tv. It has been working fine for several months. I tried unplugging it from power and hdmi but no luck. It still works with Alexa and through Amazon music in the Sonos app. I checked and the tv software is up to date. Does anyone have an idea of what I can do to solve this issue.

Having this same issue suddenly. Everything was working fine (LG OLED and Arc) but started to experience sound issues when changing input sources on the TV over the last week; and now no sound via Arc today. Unplugging, turning off/on TV worked previously but no longer. Have tried all the troubleshooting - unplugging, resetting TV, resetting Arc, checked all settings on TV. I tried plugging the Arc into the optical port with adapter and still nothing. I swapped the Arc out for my old Playbar connected to the TV via optical - it worked fine. I tried changing HDMI cables to the Arc, no luck. Seems like the Arc input is just not functioning? It cannot detect a signal any longer in TV Setup in the app. Has anyone come across another solution? Thanks!

I have the same issue. Sonos arc connected to my Samsung Q80t suddenly stopped working. Tried all reasonable troubleshooting steps (switching on and off all devices, disconnecting and reconnecting etc.) but Sonos arc can't get any signal from the TV from eARC port. My Sonos arc is less than a year old and try to return it and never look towards sonos product..so frustating.

Lightning av adapter to HDMI no longer working after IOS16 update. Updated to current iOS 16.0.3 using Apple certified cord, turned off and on, phone is updated and backed up. It work until ios16. Another phone works, but not updated to the iOS16. For example Netflix mirrors from phone to tv and will play the trailer, but once I hit play the screen goes black and says now playing on your tv. But is not playing anything. How can I fix this issue? Thank you.

Not helpful at all. The update to IOS 16 is not compatible with the AV digital lightning plug. We full time RV and do not have WiFi. We depend on the AV plug adapter. We even bought a new one. My wife just purchased the new 14, she had s 6 which worked great. Our iPad worked great until we updated to the 16. Now nothing works. You all need to fix this and quick passing the buck to the other streaming platforms.

I called tech support and got to one of the higher-ups. He actually acknowledged it is an IOS 16 series software issue and that Apple is aware of it. Trouble is, he didn't give any specifics as to when it would be fixed or how. He thought probably through another IOS upgrade. Yikes !! Very maddening.

I am having the same issues with streaming Netflix, Prime Video, HBO Max, etc. I've upgraded to iOS 16.1 as well, without any successful "fix". I am using a certified Apple OEM lightning to HDMI adapter. I've attempted the use of all SIX of my certified Apple OEM lightning to HDMI dongles with zero success of each. Either I have a black screen on my TV with audio or I have no audio and a "stuttering" video display whereby the video plays in slow motion for a second then pauses, plays again in slow-mo for a second then pauses...and so forth. Currently ONE streaming apps worked successfully...Disney+. I find it a sickening shame that I've paid for six lightning to HDMI cables at the cost of nearly $50 each and the so called "much needed" updates fail to accommodate and keep useful purpose with an Apple designed and sold accessory.

My original issue was that the "Lightning Digital AV Adapter" stopped working for one specific iPhone (connecting via HDMI to a TV for screen mirroring and Fitness+ playback). The TV would not recognize any input, the same adapter worked with a different iPhone.

My wife and I sat down this evening to watch a Prime Video we had been looking forward to watching......could not use our lightning to HDMI adaptor since updating our phones to iOS 16.2-----unbelievable. I've spent hard earned money on cables and an official Apple adapter so we can mirror movies to our TV screen in the rural area we live. Everything has worked perfectly the last couple of years until updating our iPhones to the latest software. I've been a loyal Apple customer for over 35 years and this takes the cake. We are so disappointed in how this has been handled by Apple. There should have been an immediate update released to address this issue. Apparently we are one household out of many that are presently dealing with this issue. We also do a lot of traveling in our motor home and will not be able to mirror movies to our tv until this issue is fixed. Highly disappointed.

This is ridiculous advice. Both my adaptors worked perfectly with the equipment I have until I updated to IOS 16 and now neither works! Also tried them on 2 tv's so it is not anything that I can do to fix it. This is a major bug that apple needs to fix.

Holy THANK YOU for that comment. I live remote and have spent many hours and money trying to figure out what is wrong with my phone and/or device and Apple keeps blowing it off with aloof canned suggestions and responses that are totally not helpful but incredibly time taxing.

I have a similar problem...with most of my streaming apps. Using the lightning to HDMI adaptor works fine for screen mirroring, such as using google, or photos, static content, but not for video. I've read recently that there are quite a few people with similar issues. Most of my streaming apps play, but are choppy, and have no audio. It seems this happened after I upgraded to an iPhone 14, and ios16. Everything worked great previously, iPhone 11, ios15.7. Help?

I have had my LG smart tv for about three years now. The sound for it recently stopped working yesterday feb 20th. I looked online for several solutions to solve the issue but nothing seems to work. Model number. 42LB5600-UZ.AUSDLJM.
