For some reason almost all code blocks contained suddenly html line breaks <br> that I needed to clean away.Well is should be OK now.
Hard shutdown can cause SD card corruption. That was the reason I made this system. The reset button can be used to start system when it have been shut down as long you keep it powered all the time. I am happy to hear that this little hack is useful.
I don't know where those <p> and <br> came from. Probably a copy error since I coped that part originally from my web site. It should be fine now.

It looks like I can't modify the old comment so I added the CEC as additional step to instruction itself and fixed that typo :)Thanks for pointing it out
No problem.Now back to study your code. I am sure there are some tricks I can use myself later :)
The github link seems to be broken.https://github.com/modustrialmaker/Audio-Reactive-LED-Matrix
Now the link is OK. Earlier it was shown as https://github.com/modustrialmaker/Audio-Reactive.... for me. Don't know if it was the browser or somethingThanks anyway :)

I tested another solution with TV that will turn it on and off using CECInstall cec-utils:sudo apt-get intall cec-utilsadd following lines in crontab -e# Turn TV on0 8 * * 1-5 echo "on 0" | cec-client -s# Turn TV off0 16 * * 1-5 echo "standby 0" | cec-client -sThis worked fine with TV
Great to hear.Thanks for sharing the solution
That method should only shut down the hdmi display and restart it. It does not start feh when display is restarted.You could try to use crontab to start feh at the same time hdmi turned on0 7 * * * feh --quiet --fullscreen --borderless --hide-pointer --slideshow-delay 1 /media/usb/ you should be able to replace LXDE-pi/autostart with line below in crontab. @reboot feh --quiet --fullscreen --borderless --hide-pointer --slideshow-delay 1 /media/usb/ But I have not tested crontab reboot :)
I tried method found from here http://dakboard.com/blog/diy-wall-display/ with DAKbord but it didn't worked as expected and I haven't had time to study it further.

I tried that also, but I can't remember now what software I was using :) Instead of feh, fbi (linux framebuffer imageviewer) or FIM (Fbi IMproved) could be used. I needed a simple image viewer which show automatically images from inserted USB drive.

I made similar kind of Pi display couple years ago. In my build feh is started on startup and images are displayed from attached thumb drive.https://tjutzu.kapsi.fi/wp/raspberry-pi-usb-picture-frame/
