3. No power

CAUSE: Make sure that the set top box is receiving power to function.


  • For this, ensure that the power supply in which the device is plugged in is working fine.
  • For this you can use a multimeter and check for its continuity. Continuity testing is basically checking resistance between two points.
  • Take the multimeter and set it in continuity mode and touch the tips of the probes together so that they make a beeping sound.
  • If there is no continuity, then you need to repair or replace the supply.
  • However if there is continuity, then the issue could be with the power cord.
  • Call a professional to check the cord and if it is damaged, then get it repaired or replaced.
  • Check the set top box again.
