1. Introduction

Encountering flickering signs can be frustrating, and understanding the underlying issue is crucial for swift resolution. Flickering is often indicative of problems within the internal systems, such as a failed controller or a broken connection between components. This article provides a detailed guide to help users troubleshoot and potentially resolve flickering sign issues, based on common symptoms like flickering on both sides of the sign.

2. Identifying the Issue:

If you notice your sign is flickering on both sides, it’s plausible that you’re dealing with a failed controller or a broken connection from the first video card to the controller. Accurate identification of the issue allows for more effective troubleshooting and, subsequently, resolution.

3. Troubleshooting Steps:

Follow the outlined steps below to troubleshoot and possibly resolve the flickering issue:

3.1. Disconnecting the Controller Connection to the Video Card:

• Initially, locate and disconnect the controller connection from the first video card.

3.2. Initiating the Video Card Test:

• After successfully disconnecting, press the test button on the video cards.
• This action will enable the video cards to display various colors and patterns, providing insights into the operational status of the video cards.
• Important: The controller must be disconnected for this test to work correctly.

3.3. Observation and Assessment:

• Carefully observe whether the screen continues to display a full image or pattern without any intermittent outages.
• If the screen displays correctly after disconnecting the controller, the next step is to replace the Ethernet cable between the controller and the first video card.

3.4. Ethernet Cable Replacement:

• If the flickering issue continues after changing the Ethernet cable, it is highly probable that the control card has failed and will need replacement.

4. Scheduling a Support Session

Should the issue persist after following the above-mentioned troubleshooting steps, or if guided assistance is preferred, scheduling a support session with technical experts is highly recommended. Expert guidance can help ensure each step is executed correctly, and any required replacements are accurately identified.
