Welcome to part 2 of our two part blog series regarding video wall troubleshooting. If you missed part one, you can click here to get caught up on how Auto-Condition Reporting can help you troubleshoot your video wall.

This week, we’re focusing on multiple methods of video wall troubleshooting; and how GPO Display is able to help you ensure a quick resolution to any troubleshooting issues.

Video Wall Kits

Our video wall kits, such as the Replaceable Electronics Kit (REK)(See Fig. 1) and Replaceable Controller Kit (RCK) (See Fig. 2), eliminate the need to remove panels during video wall servicing. These kits contain: either the input/controller board (RCK) or power board & input/controller board (REK) in an easily removable slide track. By keeping the boards at the rear of the display, this design eliminates run distance issues associated with other (rack-mounted) approaches to making controllers and power supplies readily accessible.

In the event of a board failure, move the mounted display into its service position. From there, the Replaceable Electronics Kit (REK) may be removed from the rear of the panel by loosening two thumbscrews and pulling downward from the rear/bottom of the LCD panel. The Replaceable Controller Kit (RCK) works in a similar fashion but is located at the right side of the display. Once the kit has been removed, a replacement kit can then be inserted and the thumbscrews re-tightened. This entire operation can be done in 5-10 minutes without removal of a single LCD panel. This reduces the amount of technicians required for servicing, and greatly reduces the cost of labor associated with the vast majority of service operations.

Onsite visits during installation

GPO Display also offers onsite supervision and final commissioning for every video wall installation. We assist with color matching/calibration, fine-tune alignment and configuration of your new video wall. We can either guide you through every step of the installation or arrive after displays/mounts are hung for touch-up and a factory stamp of approval. This also helps us build a profile of the installation for better troubleshooting should an issue arise. In some cases, potential issues are caught before they pose a problem, such as: potential ventilation issues, unforeseen hazardous environmental conditions and problematic implementation of system design.

If Auto-Condition Reporting (ACR) is being implemented for the first time, final commissioning is strongly recommended to ensure proper setup and function of the ACR for first-time buyers.
