Losing display output after 5 minutes

[danjvd]

I’m have been running into a issue over that past week, were the HDMI connection will drop and the TV will stop displaying. I have check TV setting for a sleep mode, changed out Raspberry Pi’s, updates, and replaced the micro card. I do have the background changing ever 60 sec and still the TV will lose the HDMI signal. Looking for other troubleshooting steps.

@danjvd are you sure it’s the display turning off ?

if you do alt-spacebar does the appenubcome down?

if so, this means the app has crashed, leaving a black screen

@sdetweil I’m able to VNC to the pi, and when I move the mouse the TV will turn back on. It will then stay on for 5 minutes before TV lose HDMI connection. I have also keep the VNC connection open and watch the TV lose signal and the app continue to work.

I have missed with the PI config file to increase the HDMI signal but same outcome.

Also, I did setup CEC, 6 months ago, to control when the TV turns on and off. I was thinking there was an issues with the pi, so I created a con job to turn the TV, then restart the PI. This setting worked for about a week. Now if I do not restart the PI it comes up with no HDMI signal.

I wondering if its an issues with the TV itself?

@danjvd if you stop MagicMirror, does the screen turn off?

[danjvd]

@sdetweil I have not tried that. I will let you know later today of the outcome.

Thanks Sam!

@danjvd It sounds as if your screen saver wasn’t disabled correctly?

@zoltan if u run my install script it will turn off screensavers if u say yes.

also a separate script if u change your mind

we are still waiting to see if it’s mm related or not

[danjvd]

@sdetweil With MM turned off, the Pi keep display HDMI without issues. Are there any error logs that I should look at?

@Zoltan Thanks for the steps. I did complete this when I first created the MM pi over a year ago. It always a good thing to veirfy!

@danjvd ok so this means one of the modules you are using is turning off the display

can you do

grep module: ~/MagicMirror/config/config.js

to show us a list of the modules used

@sdetweil said in Losing display output after 5 minutes:

grep module: ~/MagicMirror/config/config.js

Here are the modules that I have been using for the past 6 months before the issues started. I have not added/removed any modules after this setup, only updates.

  module: "alert",
  module: 'MMM-BackgroundSlideshow',
  module: "updatenotification",
  module: "clock",
  module: 'MMM-CalendarExt2',
  module: "MMM-OpenWeatherMapForecast",
