A blank display with the Ethernet cable connected is caused by the tracker being powered on with the cable already plugged in. This is a known software issue, not a hardware fault, and it does not damage the unit. Begin by checking when the cable was connected, as this confirms the cause. ## First, check when the Ethernet cable was connected **Connected before the tracker was powered on:** this is the cause. Continue below. **Connected after wwwOK appeared on the display:** this article does not apply. Contact us using the details below. When the cable is connected at power up, the tracker does not complete its normal startup. The display stays blank and the Tracker Setup page cannot be reached, so the unit appears frozen. ## Next, select the option that describes your situation **The display stayed blank after power up** 1. Power off the tracker. 2. Disconnect the Ethernet cable. 3. Power the tracker back on. 4. Wait until the display shows normal startup information. 5. Reconnect the Ethernet cable. The Tracker Setup page should now be reachable as normal. **The display is active, but the Tracker Setup page will not load** The tracker has started normally, so the issue is with the connection to your laptop. Confirm that your laptop shows a new network before opening the browser, and that Wi-Fi and Bluetooth are disabled. On the first connection, the page can take up to 5 minutes to load while it downloads its style sheet from the tracker. To avoid this in future, always power on the tracker before connecting the Ethernet cable, and connect only once **wwwOK** appears on the display. Do not power cycle the tracker with the cable connected. ## If the issue remains unresolved Email [support@skytrac.ca](mailto:support@skytrac.ca) or call [+1 (250) 765-2393](tel:+12507652393) with the following: - Unit serial number and aircraft registration - When the Ethernet cable was connected - What the display shows at power up, if anything - Whether the display remained blank after a restart without the cable - Whether the tracker is still reporting on your tracking platform Most of these details will be available from the checks above.   - [Flight Following and Account Management](https://go.skytrac.ca/knowledge/flight-following-and-account-management#main-content) - [TrooTrax](https://go.skytrac.ca/knowledge/flight-following-and-account-management#trootrax) - [SkyWeb](https://go.skytrac.ca/knowledge/flight-following-and-account-management#skyweb) - [WebSentinel](https://go.skytrac.ca/knowledge/flight-following-and-account-management#websentinel) - [Asset Manager](https://go.skytrac.ca/knowledge/flight-following-and-account-management#asset-manager) - [Transceivers and Hardware](https://go.skytrac.ca/knowledge/transceivers-and-hardware#main-content) - [ISAT-200A](https://go.skytrac.ca/knowledge/transceivers-and-hardware#isat-200a) - [SkyNode S100 and S200](https://go.skytrac.ca/knowledge/transceivers-and-hardware#skynode-s100-and-s200) - [DZMx](https://go.skytrac.ca/knowledge/transceivers-and-hardware#dzmx) - [RockAIR](https://go.skytrac.ca/knowledge/transceivers-and-hardware#rockair) - [Sky Connect Trackers](https://go.skytrac.ca/knowledge/transceivers-and-hardware#sky-connect-trackers) - [DLS-140](https://go.skytrac.ca/knowledge/transceivers-and-hardware#dls-140) - [IONode](https://go.skytrac.ca/knowledge/transceivers-and-hardware#ionode) - [SKYTRAC Mobile](https://go.skytrac.ca/knowledge/skytrac-mobile) - [General Troubleshooting & FAQ](https://go.skytrac.ca/knowledge/general-troubleshooting-faq) - [Activation and Deactivation](https://go.skytrac.ca/knowledge/activation-and-deactivation) - [Installation Manuals](https://go.skytrac.ca/knowledge/installation-manuals) - [Cockpit dialers and displays](https://go.skytrac.ca/knowledge/cockpit-dialers-and-displays#main-content) - [CDP-300 and DVI-300](https://go.skytrac.ca/knowledge/cockpit-dialers-and-displays#cdp-300-and-dvi-300) - [MMU-II](https://go.skytrac.ca/knowledge/cockpit-dialers-and-displays#mmu-ii) - [Contacting SKYTRAC](https://go.skytrac.ca/knowledge/contacting-skytrac#main-content) - [Technical Support](https://go.skytrac.ca/knowledge/contacting-skytrac#technical-support) - [Sales](https://go.skytrac.ca/knowledge/contacting-skytrac#sales) - [Billing](https://go.skytrac.ca/knowledge/contacting-skytrac#billing) - [Aftermarket](https://go.skytrac.ca/knowledge/contacting-skytrac#aftermarket) [![SKYTRAC Logo-White](https://go.skytrac.ca/hs-fs/hubfs/SKYTRAC%20Logo-White.png?width=170&height=31&name=SKYTRAC%20Logo-White.png "SKYTRAC Logo-White")](https://www.skytrac.ca) Technical Support [support@skytrac.ca](mailto:support@skytrac.ca) [+1 250 765 2393](tel:+12507652393) Answered 24/7 Aftermarket and RMAs [aftermarket@skytrac.ca](mailto:aftermarket@skytrac.ca) Repairs and warranty Billing [ar@skytrac.ca](mailto:ar@skytrac.ca) Invoices and payments Sales [sales@skytrac.ca](mailto:sales@skytrac.ca) Quotes and orders Popular Topics [Flight following](https://go.skytrac.ca/knowledge/flight-following-and-account-management) [Hardware](https://go.skytrac.ca/knowledge/transceivers-and-hardware) [Activations](https://go.skytrac.ca/knowledge/activation-and-deactivation) [SKYTRAC Mobile](https://go.skytrac.ca/knowledge/skytrac-mobile) Resources [Documentation Center](https://www.skytrac.ca/resources/documents/) [Videos](https://www.skytrac.ca/resources/videos/) [Webinars](https://www.skytrac.ca/resources/webinars/) [Certifications](https://www.skytrac.ca/company/certifications/) News and Media [Press releases](https://www.skytrac.ca/resources/press/) [Case studies](https://www.skytrac.ca/resources/case-studies/) [White papers](https://www.skytrac.ca/resources/white-papers/) [Magazine](https://www.skytrac.ca/resources/magazine/) Connect [LinkedIn](https://ca.linkedin.com/company/skytracsystems) [Facebook](https://www.facebook.com/SKYTRAC-Systems-Ltd-344178569011082/) [X](https://twitter.com/skytracsystems) [YouTube](https://www.youtube.com/channel/UCQedmJEZf8TvepEuDm9W3tQ) Copyright © 2026 SKYTRAC Systems Ltd.
