  If the display on your SMC Networks Controller is turning off or sections are missing, it could be due to several reasons: * The power supply might be incorrect; ensure it's between 21.6 to 26.4 VDC. * Wiring might be faulty; check and correct the wiring. * The lead wire may be broken; replace it if necessary. Also, consider that the product might be in Display OFF mode, and you may need to set up the product again. If none of these steps work, the product may have failed and needs replacing.

If the issue persists, the product may have failed and require replacement.
