Why doesn't my SDA screen power up after restarting the unit?
The SDA screen includes built-in safety mechanisms designed to extend its lifespan and protect it from damage caused by sudden power fluctuations.
One of these features is a cooldown period that activates when the unit experiences a brief power interruption—such as being powered off and then quickly turned back on. If the screen loses and regains power within a few seconds, the system may prevent it from powering up to ensure the cooldown process is completed properly.
To resolve this issue:
- Power down the SDA unit completely.
- Wait at least 10 seconds before turning it back on.
- This allows the screen to complete its cooldown cycle and ensures safe reactivation.
- If the screen still does not power up after following these steps, please contact technical support for further assistance.
