      Try adding hdmi_force_edid_audio=1 in addition to the other commands, this might restore your audio settings. You can also force a specific resolution in the config.txt- see these instructions. It seems your monitor doesn't cooperate very with the Pi HDMI detection, so you might try to set explicitly the resolution via the hdmi_group/hdmi_mode parameters - https://www.raspberrypi.org/documentation/configuration/config-txt/video.md.

        @mitu thank you for the reply, I'll give it a go later. One more thing am I editing this in the right place.

        I press f4 on my keyboard and type
        sudo nano /boot/config.txt

        Thanks again

          If you're asking if this is the right way to edit the config.txt file, then yes.

              @Asha1980 You may also need to disable EDID detection alltogether, as I had to do when my hdmi splitter required that I turn the Pi on, then off, and then on again after the Pi was powered off for more than half an hour or so. You can disable EDID detection by adding this line to your /boot/config.txt:

              hdmi_ignore_edid=0xa5000080
              

              This is also mentioned in the link that @mitu gave you, but it can easily been overlooked.

              edit: just some small corrections in my wording. :)

                        After taking the advice of some rather helpful people on here, here's how i managed to get my Pi3 to turn on once the tv/monitor was powered on.

                        While in Retropie press f4 on your keyboard to force close retropie , which then will bring up the page to where you access the config.txt file which you will need to edit.
                        Type the following sudo nano /boot/config.txt that will the open up the config.txt file, then scroll to the bottom and type the following hdmi_force_hotplug=1 press enter then type hdmi_force_edid_audio=1 and then finally this hdmi_ignore_edid=0xa5000080 save the file and then reboot Pi,

                        I found everything was working perfect.

                        apologies if this doesn't read very well

                        many thanks all

                          Thanks for sharing your solution. As for readability, it helps to put commands etc. in single grave accents (`) to highlight them and use a fixed-width font like this.

                          See the Markdown syntax for more formatting options. It's also linked at the upper right corner of the input area of a new post (the small grey "compose").
