Suntronics Training & Support

Know Your Screen.
Run It With Confidence.

From first power-up to game day, Sunday morning, or a busy retail schedule, Suntronics helps customers understand how to operate, maintain and troubleshoot their LED display systems.

Start Strong

Getting Started With Your LED Display.

Most display issues are easier to solve when the basic signal path is understood. Think of the system as four pieces: power, content source, control hardware and the LED display itself.

Power & Startup

Confirm power is present at the display, controller and source device before changing software settings. If multiple components are powered separately, verify each one is on and has completed its normal startup cycle.

Know The Signal Path

Identify what sends content to the display: a media player, Windows PC, Mac, scoreboard computer or dedicated controller. Then verify how that signal reaches the LED processor — HDMI, network, fiber or another transport method.

Connectivity

Suntronics systems may use cellular, Ethernet, wireless network bridge or fiber. If a display is offline, check link lights, cabling, switch or bridge power and whether the control device still has network access.

Resolution Matters

The source resolution should match the LED canvas or processor configuration. A mismatch can create black borders, stretched images, cropping or an image that appears only on part of the display.

Check The Entire Screen

Before an event or campaign goes live, inspect the complete display for dead areas, color differences, loose cabinet connections or content that is being clipped at the edges.

Save A Known-Good Setup

Once the system is running correctly, document the working resolution, cabling, software settings and controller configuration. A known-good baseline makes future troubleshooting much faster.

Make It Look Right

Content & Software Best Practices.

LED displays reward simple, readable content. The farther away the audience is, the more important contrast, type size and message duration become.

Content Checklist

Design At The Correct Aspect RatioCreate graphics and video to match the actual LED canvas whenever possible.
Use Strong ContrastBright text against a dark background or dark text against a bright background reads best at distance.
Keep Messages ShortFor roadside or high-motion audiences, limit the amount of information presented at once.
Use Large TypeThin fonts and small text can disappear when viewed from across a gym, parking lot or highway.
Test Before The EventRun the actual playlist, scoreboard feed or presentation before doors open or traffic arrives.

Game Day / Presentation Workflow

Confirm Extended Display ModeFor presentation computers, verify the LED output is an extended desktop rather than an unintended mirror.
Preload MediaKeep videos, sponsor ads and graphics local to the presentation computer when possible to avoid network buffering.
Build A Repeatable PlaylistUse labeled folders or playlists for pregame, live action, breaks, sponsors and postgame content.
Separate Audio From Video TroubleshootingIf the picture is working but audio is not, treat the sound path as a separate system instead of changing LED settings.
Arrive EarlyGive yourself time to reboot or reconnect equipment before the audience arrives.
Protect The Investment

Routine Maintenance That Matters.

LED displays are built for long service life, but regular inspection helps catch small issues before they become event-day problems.

Visual Inspection

Periodically inspect cabinets, modules, mounting hardware, seals and cable entry points. Look for obvious impact damage, corrosion, loose fasteners or water intrusion.

Airflow & Cleanliness

Keep ventilation areas free of leaves, dust buildup and debris. Electronics last longer when cooling paths are not blocked.

Weather Awareness

After major storms, inspect outdoor equipment for physical damage, water intrusion or power-related problems before assuming a software issue.

Cables & Connectors

Loose or damaged HDMI, Ethernet, power and data connections are common causes of intermittent issues. Reseat connections only when it is safe to do so.

Periodic Test

If the display is seasonal, power it up and run content periodically instead of waiting until opening night to discover an issue.

Document Changes

Record network, controller, resolution or software changes. When someone modifies the system later, the support team can understand what changed and when.

Troubleshooting

Check The Simple Stuff First.

Most display problems can be narrowed down quickly by identifying whether the issue is power, signal, network, source resolution or the display hardware itself.

Start with power. Verify the display, controller or processor, and the source computer or player are all powered on. Then verify the source device is actually outputting video and that the correct input is selected on the controller. If possible, test the source on another monitor to confirm the source is producing an image.
Check the signal path from the source device to the LED processor. Confirm HDMI, adapter, extender or fiber devices are powered and connected. If using a laptop or Mac, confirm the second display is enabled and that the computer recognizes it.
This usually points to a resolution or scaling mismatch. Check the computer output resolution, LED processor input settings and the configured LED canvas size. Avoid changing multiple settings at once; make one change, test it and document the result.
If only part of the display is affected, the source signal may still be good. Note exactly which cabinet or area is affected and whether the problem is black, frozen, discolored or intermittent. That information is very useful when contacting Suntronics support.
Verify the controller has power and check the communication path. For Ethernet or wireless systems, confirm network equipment is powered and link indicators are present. For cellular systems, verify the controller has service and has not recently been moved or reconfigured.
Contact support when troubleshooting would require opening energized equipment, climbing, accessing internal electrical components, changing processor configuration you are not comfortable with, or when the problem persists after basic power, signal and connectivity checks.
Still Need Help?

Talk To Suntronics Support.

If the quick checks above do not solve the issue, have your display location, source device, controller information and a photo or short video of the problem ready. That gives the support team a much faster starting point.
