Warning Icons on the Yodeck Player based on Raspberry Pi
Two types of warning icons can appear in the right-hand corner of the screen when the Yodeck Player based on Raspberry Pi is not functioning optimally.
Let's have a look at their significance and how you can troubleshoot.
Lightning / Thunderbolt / Thunder Icon
This indicates that the power supply is unstable, the player is underpowered, and this situation could lead to corruption of the SD card and overall instability.
Switching to a new power adapter is best as soon as possible.
Raspberry Pi 2 needs a 5V/2A power adapter
Raspberry Pi 3B and 3B+ needs a 5V/2.5A power adapter
Raspberry Pi 4 needs a 5V/3A power adapter
Temperature / Thermometer Icons
The thermometer icons mean the Player's main chip is hotter than usual.
The half-red thermometer icon means that the Player's chip temperature is between 80 and 85℃, and the Player will throttle the CPU (decreasing performance) in an effort to keep the temperature below 80℃.
The completely red thermometer icon means that the Player's chip temperature is above 85'C and the Player will throttle both the CPU and GPU (decreasing performance even further) in an effort to keep the temperature below 85℃.
Why the overheating?
Most probably, content pushed to players is somehow too "heavy". You might not realize it, but adding too many Playlists or transparent content might put too much of a burden on the Player.
What can you do?
Here are some possible remedies:
Try removing some content, combining multiple Widgets into single Apps, or contacting our support team and asking for help to optimize your Layout or content.
Add a passive heat sink. They are cheap. Note that our Players come pre-installed with an aluminum case, which provides better heat anticipation.
Available Heatsinks
Try using a metal case instead of a plastic one. If using a case with a cover (like the Official Raspberry Pi case we ship over with our Players), try removing the cover to allow the chip to cool.
Place the Player in a well-ventilated space.
How to disable both icons
You can override standard behavior and disable both icons. Make sure that you understand the risks of doing so.
Go to the "Monitors" list and edit the monitor in question.
Click on the "Advanced" tab.
Ensure the "Allow Raspberry config.txt Override" toggle is set to "ON".
In the "Raspberry config.txt Override Directives" text area, you will have to enter the following configuration line:
avoid_warnings=1
After you are finished, click the "Save" button.
The Player will reboot, and you are set to go.
Keep this in mind!
We do not recommend that you remove the warning icons without troubleshooting. You should investigate this and fix the issue rather than ignore the warnings.
