      Hello,

      Here is the story, my Raspberry was working fine on my TV (HDMI) then I went away from home for a week with my Raspberry and I plugged in another TV (HDMI) with another HDMI cable but with the same power supply and it still worked fine.

      Except that the sound wasn't playing so I just went in the RetroPie menu to select "HDMI audio" and everything was ok (the resolution wasn't good but it was an old HDMI TV).

      But then I returned to my home and now it seems that my TV for some reason doesn't detect the Raspberry anymore?

      I tried with 3 different HDMI cables but... still the same result!

      I also tried to make these changes in the config.txt but nothing worked.

      hdmi_force_hotplug=1
      hdmi_drive=2
      

      Or

      hdmi_group=1
      hdmi_mode= 4
      

      And even this

      hdmi_safe=1
      

      Thank you for helping me.

        If you run tvservice -s from the PI, does it output something ? On a connected TV, should say something like

        pi@retropie:~ $  tvservice -s
        state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive

          @mitu Thank you for your answer, this what I get:

          pi@retropie:~ $ tvservice -s
          state 0x12000a [HDMI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive
          

          Maybe this is a clue, the 4:3 must block the signal or something, how do I change this?

            @malixx Actually, I think it's that DMT part that's causing signal issues. Usually, CEA is used for televisions, while DMT is used for computer monitors.

              @supercatfooz Ok I trust you! But what should I do, if there is something I can do about it?

                @malixx Try running something like tvservice -p to start the TV service with preferred settings, then starting emulationstation.

                    @malixx Usually tvservice -p does not take any arguments, I think just tries to get the optimal setting from the monitor and set it. Where do you get this error and what command are you trying ? See Video modes docs on the parameters availble.
                    Alternatively, you could run sudo raspi-config and configure the video output from the RPI configuration utility.

                      @mitu Ok I thought I had to put the everything after tvservice -p(btw it does nothing) so I went in sudo raspi-config and tried to change some settings, but still nothing...

                      Edit: I changed the resolution to 1080p in the sudo raspi-config but when I type tvservice -s these settings are still showing
                      state 0x12000a [HDMI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive

                          @malixx What is the resolution on your TV set ? Is it really '640x480' ? Can you try changing it and see if it's picked up by RP ?

                              have you read through this https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

                              Which values are valid for my monitor?
                              Your HDMI monitor may only support a limited set of formats. To find out which formats are supported, use the following method:

                              Set the output format to VGA 60Hz (hdmi_group=1 and hdmi_mode=1) and boot up your Raspberry Pi
                              Enter the following command to give a list of CEA-supported modes: /opt/vc/bin/tvservice -m CEA
                              Enter the following command to give a list of DMT-supported modes: /opt/vc/bin/tvservice -m DMT
                              Enter the following command to show your current state: /opt/vc/bin/tvservice -s
                              Enter the following commands to dump more detailed information from your monitor: /opt/vc/bin/tvservice -d edid.dat; /opt/vc/bin/edidparser edid.dat

                                Hello @mark1986, thanks for trying to help I got this:

                                I will try to understand and correct the problem with your link, but if you have any solution, I'm all ears!

                                    @malixx If it takes you this much time, isn't it easier to start with a fresh image and copy some of your old configs and roms to your new image?
                                    Also always good practise to backup your image often so you won't have to deal with stuff like this.

                                    I'm not tech savvy so all I can think of is this:
                                    Have you tried both turning the tv on before turning the Pi on and turning the tv on a minute after turning the Pi on? This makes a difference in how the Pi boots up. If your tv is already on then it uses that resolution. If your tv is not on (and hdmi video is forced) then it will use a low resolution.

                                    And have you used your hdmi port with another device to rule out your tv causing the issue?

                                      @bobharris Thanks for the reply, I have another SD Card with a fresh install and it does the same thing.

                                      I also tried both turning the tv on and off!

                                      I tried with different ports and also different cables... same result :(

                                        Might be a hardware problem with your Pi then..

                                            Ok just to be clear, the malfunction was because of my NESPI Case from Retroflag (I have the older version) maybe it drains too much power! Sorry I should have told you about the case, I thought it won't be the problem because it worked on another TV...
