So I install the latest image of retropie, and boot it up on my rpi3. Plug it into my hdmi arcade cab, connect to wifi, add games from pc via wifi, force audio to 3.5 or I'd have no sound, restart, play roms just fine, then here is when I have the issue... I shut it down. It doesn't matter how. But after I do I have nothing when I try to restart. I thought corrupt sd card but it happens on all that I try on. For days I have had to reimage and go through all this over and over again.

I finally realized it's booting, but just not displaying. I can connect to it via wifi and even add roms. I'm not a bash or Linux guy but I'm tired of reimaging. What can I do to force this to display on my hdmi after rebooting?

Without a display, I'm not sure how to diagnose/fix this issue. I can tell you I'm for sure over reimaging though so if anything can be done please help!

Assuming the RPi is booting as stated in your question


  • You can force the RPi to display through HDMI even if no HDMI screen is detected. this can be achieved by appending
    hdmi_force_hotplug=1
    at the end of config.txt


    It is not necessary but you should also append
    hdmi_drive=2
    this fixes certain sound problems

  • If you still dont have any HDMI output then

    You should append
    hdmi_safe=1
    According to the documentation, this line is equivalent to setting up the following settings:


hdmi_force_hotplug=1
hdmi_ignore_edid=0xa5000080
config_hdmi_boost=4
hdmi_group=2
hdmi_mode=4
disable_overscan=0
overscan_left=24
overscan_right=24
overscan_top=24 
overscan_bottom=24

  • Insufficient power supply

    If despite all your attempts the Raspberry Pi still not display anything on HDMI, it can come from a simple power supply problem.
    In other words, the power delivered by your power supply is enough to run your Raspberry Pi, but not to power the HDMI connection.
    So switch to a power supply of 5V, 2.5A .


  • Conclusion

    if your RPi still doesn't show the rainbow screen then it's a hardware problem not software, good luck finding the problem.


Hope this helped
