  • [RPi5 2GB] Scrambled Display on Sony Bravia X90L

    Wait...what?!

    No, you are correct. This is a 2GB. I'm sure I ordered an 8GB because my 2GB Pi4 has been OOM'ing and it was worth the $30 difference to not have to deal with that crud. The invoice says 2GB though.

    ?(

    What a cluster.

    Anyway, I appreciate the help, y'all. I hope this thing will be ok with 2GB because I don't feel like going around and around with Cana on this. Particularly after the SD card reader they shipped with the kit was so unreliable.

    This plus my PiKVM having a hardware failure after only a few months. This might be it for me and Pis. :cursing:

    I guess it's off to Lilliputing to see what other SBC form-factor comes close for power consumption and ecosystem. I keep seeing other ARMs popping up...

    As I've gone through each round of testing I've been doing a run with both stable and nightly. The results have been the same between versions each time. HOWEVER, it looks like the web site sorts ascending by default and I might/probably have been grabbing an old nightly.

    I just flashed and booted to https://test.libreelec.tv/13.0/RPi/RPi5/…-f5bd1a2.img.gz...

    AND IT WORKS!

    So I believe, once we got to using the nightly, this can be attributed to PIBKAC almost exclusively. In my defense, as such, I was bouncing between prepping a motorcycle for a rally, building a greenhouse, and this project depending on how overheated I was at the moment. lol

    I'm so happy this is sorted. I will continue to run the nightlies until the necessary drivers have landed in GA and then I will settle on stable.

    Thanks a ton, y'all. My kid will be happy because it seems like tonight might be a movie night. :D

    Ok, I just wanted to make sure there wasn't something easily grep-able to indicate rez scaling. You just have to look for "GUI format" and "Display" numbers having a factor.

    I dropped the "M" and it didn't make a difference. I'll post another debug log below...

    Also, fwiw, I moved the Pi over to the -- as the kids say -- "mid" Dell 27" monitor with the same results. So I kinda suspect the Bravia is not the root cause here.

    I would say perhaps I have a fault in the vid hardware except that Raspberry Pi OS is able to send X11 desktop output to both the Bravia and Dell w/o difficulties.

    Oh, fwiw, I don't think I mentioned this before...I've put the TV on the network and made sure it is up-to-date for software from Sony. One less variable.

    I made the 30Hz adjustment and rebooted and I'm still in the corrupted state. I'll go through the menus and see if I can find anything about rez upscaling but can I ask where in the debug output you were able to identify that behavior? Both out of curiosity and out of then being able to validate that I have disabled rez scaling.

    Y, too many windows open. I mounted the .img file to do some inspection and accidentally modded it rather than the SD card I had just written and mounted. I have SSH now though.

    After setting the video=... and rebooting I tried both HDMI-4 and HDMI-1 on the Bravia and toggled the Enhanced Format to see if that would resolve. Nothing so far. Same result.

    I'm going to try the Dell monitor next but there's no wired network over there so...

  • [RPi5 2GB] Scrambled Display on Sony Bravia X90L

    Hmm...

    I added the video= line but I'm still getting the same corrupted video.

    I also added "ssh" to the end(?) of config.txt but no sshd running:


    Host is up (0.00026s latency).
    Not shown: 997 closed tcp ports (reset)
    PORT    STATE SERVICE
    111/tcp open  rpcbind
    139/tcp open  netbios-ssn
    445/tcp open  microsoft-ds


    I couldn't find anything on the wiki, SEs, or via LLM that suggested I needed anything fancier than just appending as the last line of the file.

    I plugged the Pi into an low-end Dell 27" monitor just for kicks. Same result. Also swapped cables and tried both the stable and nightly builds. Also same results.

    Seems like there is some sort of problem with Pi5. Or at least *my* Pi5.

    There's a timer on my ability to post so rather than respond to folks with quotes I'll have to roll everything up in a single post...

    HarryH Wow, that was buried in the menus! You must have either a photog memory or a Bravia. :D As it turns, that setting was already enabled.

    chewitt This corruption is happening at first boot. I'll look to see if there is a single user mode or some way to pause the boot loader to see if I can add those troubleshooting options. Thx. Stand by.

    On a related note, I'm not married to the Pi5. There are plenty of things I could do with it other than use it as a media node. Is there another set of kit that works well with LibreELEC and has a similar form factor? I have tons of solar on the house so I'm not super concerned about if another set of kit uses a bit more power. I don't really want to go down the route of a SFF because I'm limited for space in this particular location.

    Quote from HarryH

    Do you use a RPi5 2GiB model? I can remember that you should use a current LE nightly to support that. I think the scrambled picture looks so...


    Mine is actually an 8GB. But perhaps the issue is not a function of amount of memory but something else?

  • [RPi5 2GB] Scrambled Display on Sony Bravia X90L

    The Pi is sitting on a wooden shelf with the only nearby devices being a sound bar and the TV itself. I don't have a great way to test the interference hypothesis but I think it is ruled out by some other tests.

    I wrote RPIOS to the same SD card and booted that attached to the screen. It was able to negotiate a signal with the TV without a problem though I did forget to check if it was 4k. I guess perhaps I will go back and check that later.

    As a final set of steps I wrote LibreELEC to the SD card with two different card readers and in both cases the boot results in the corrupted screen scenario I first posted.

    So not entirely sure how to proceed. I will go check for 4k with RPIOS and I will see if I can any information about how "Deep Color" might translate to the Bravia settings.

    Hey, folks.

    Please be patient with me as I barely pay attention to any of tech around TVs, variants of HDMI, variants of 4K/8K, etc. We are simple folks who just want to watch a digitized collection of our old movies. ;)

    I have a Bravia X90L series (55") and I just picked up a Pi5 CanaKit with all of the bells-and-whistles to double-sided tape a LibreELEC media center to the back of the TV over the fireplace. The version of LibreELEC is recent -- whatever came out of the business end of rpi-imager this afternoon.

    I basically don't get a signal from the Pi5 at any of the HDMI ports with the exception of the highest-end HDMI-4 (4K and a bunch of whiz-bang I don't understand) port. At Pi boot I get the LibreELEC boot splash and then the attached not-quite-right display state. I can use the remote to navigate something as I can hear the UI element audio indications but I cannot see what I'm doing in the UI.

    I've seen some posts about adjusting some display settings (ex: Deep Color) but I'm not finding them buried anywhere in the various menus of the Bravia.

    Perhaps someone could take a look at the picture and point me in a possible direction?

    thx
