RPi 4 and no video out

  • Hi, I just got my new RPi 4 and the video works fine (sans some green dots, I was blaming the cheap hdmi cable) on a new tv but on my older tv I get no video at all.

    This is my config.txt and distroconfig.txt currently.

    What's commented out in the config.txt I have tried in the past to no avail. I'm using the hdmi port closest to the usbc port.
    Potentially unrelated but I did a restore of a kodi backup from a raspberry pi 3.

  • Sorry, it's a Sony Bravia KDL-32BX330. It's a 720p 32 inch tv.

    EDIT: I'm not sure what else to provide. RP3 plugs and plays just fine btw.

  • Please provide a full debug log.

  • I can't seem to get any video out on any tv or monitor now. I'm thinking it might be a bad micro HDMI to HDMI cable, I'll try to replace it and update them. Until then I can't enable logging via ssh?

  • I have an similar problem.


    After about 2 weeks of running an RB 4 with libeelec 9.1.501 suddenly without an update or another change, the CEC doesn't work.

    After a few tries to fix that and some reboots, I didn't get an Video Signal.

    An RB 3 with the same HDMI-cable works fine, the mirco HDMI to HDMI adapter change had no effect.

    An new install of Kodi change nothing.

    I can reach the RB4 via SSH.

  • If it happens that suddenly, then perhaps we shouldn't rule hardware failure... I hope I'm wrong.

  • Sorry to hear patrik.
    I bought an adaptor instead and everything is working fine! (maybe running a bit hot even in the flirc case)

    Be wary of cheap micro hdmi to hdmi cables on amazon.

    So I got an new RB 4. Same problem.

    But now I tested the output on 3 different devices.

    On LG OLED, the original place of the RB 4 and were that worked 2 weeks, still no signal.

    At my BenQ Pc monitor, signal.

    At my old Samsung also signal.


    I was using diffent cables, same cabels, diffent and same adapters.

    The LG shows that "HDMI x is ready" but I didn't get an signal.


    LG tells me, if other devices works, thats not their failure.


    And idea from you?


    Thanks

  • And the power supply is the original?

    Power supply is very important when it comes to hardware failures.

  • Did you try both hdmi outputs?


    Here only the one near the usb power slot outputs a video.

    Power supply is very important when it comes to hardware failures.

    Power Supply was first an 2 Amps supply, with that ist was running the first 2 weeks and is running with that on the other display.

    I tested an 12Amps supply with the same outcome.

    Yes, both.

    But I testing different things mostly only with the HDMI 0 output near the power supply plug.


    Thanks


    Edit: now with an brand new HDMI-Cable it works with the LG TV ( again).

    I don't get it, but it's ok.
