What to do if there are intermittent or missing signals on all outputs of Miranda NV8144 Switch?

  Margaret JonesJul 25, 2025
  If all outputs on your Miranda Switch have intermittent or missing signals, begin by inspecting the control card responsible for processing sync references. Try switching to the backup control card to see if this resolves the issue. Also, check the PS8100 power supply module for potential low voltage at the test points. If low voltage is detected, replace the PS8100 power supply module.

What to do if some cards or PS8100 power supply modules are not powering up on Miranda Switch?

  If one or more cards or PS8100 power supply modules in your Miranda Switch are not powering up or operating correctly, ensure the card or module is fully seated in the frame. Try resetting the card or module by reseating it. Check that all five green LEDs on the front of the PS8100 power supply modules are lit. If an LED is not lit, it indicates a branch circuit may be faulty, which could affect only certain modules in the frame. Replace the PS8100 power supply module.
