LED Signs Troubleshooting:Power Supply Problem

  Troubleshooting led signs may initially seem quite overwhelming since there are tons of variables that impact how a system works.
  You have to know that one of the leading causes of downtime is a supply power failure. When the LED signs is exhibiting strange or weird issues, there's a huge chance that it is a supply power problem.
  Is the led signs getting enough power? That question should be the first thing you should ask.
  Power issues create different symptoms that are challenging enough to be recognized in an instant. If there are led signs issues that you cannot fix through normal troubleshooting methods, checking the power source is usually your best bet.
  It is always good to recognize common supply power failures that occur. If any of the situations occur below, the power supply should be verified immediately:

       Tips:7 Tips To Choose The Right LED Display Supply Power
led signs
  If led signs goes blank and there is no communication with it
  If led signs is not working after normal troubleshooting procedures
  If led signs is using portable power (like 208 VAC), particularly during special events
  If led signs uses a generator for power
  If led signs is on multiple circuits and some sections remain blank
  System Voltage
  Electrical devices and LED signs devices are configured to work on certain voltage ranges. Most devices work on 120 volts or 230 volts. Some devices can operate within a 10% range, but must remain within that tolerance. This is why you must not run an LED signs on 230 volts that is configured to work on 120 volts. Running a digital signs on a different voltage will cause major component damage and complete signs failure.
  Main Power Source
  Tripped breakers at led signs age or at the building
  The signs is completely blank on both sides without any communication
  Power interruptions also occur from the main power source of led signs age. This is caused either by the power panel in the building or led signs ; or by a break in the line itself.

  Voltage drop
  Great distance of LED signs from the power source
  Components work for a certain period, but fail repeatedly.
  Sign or components drop at random intervals
  Electricity travels through wires. Voltage decreases as the length of the wire increases. The voltage drop is about the gradual diminishing of voltage as electricity travels away from the power source. A voltage decrease causes lower power supplies for led signs  and its components.
  Wire Size
  Lower voltage measured at led signs  than the main power source
  Semi melted or discolored wires/connectors
  Small extension cords not suitable for commercial or heavy duty use
  Wire size is vital in providing safe and adequate power to digital signsage. A smaller wire size will cause damage to led signs  and its electrical components. It will result in voltage drop and will the wire to melt and overheat.
  Loose Connections
  led Sign works in warm weather only
  led Sign flickers on and off or only work some of the time
  Power is measured on the terminal side, but no power register on led signs
  Loose connections occur when the thread that is stitched through the LED becomes too loose.
  All electrical connections must be tightly pressed up for the electricity to flow through the circuit and for led signs age to function in the right way. Loose connections tend to occur during initial installation or during system service work. This can lead to excessive heat.
  Changes in temperature also affect electrical connections, causing led signs  not to work in cold weather.
  Breaker Amperage
  Breakers acts automatically by interrupting the electrical flow in a circuit in case of an overload or short. LED signs pulls a certain amount of amps, based on its configuration. It is important to use breaker size that is sufficient for this amperage. When led signs age exceeds the breaker's amperage rating, the breakers will trip.
  In those instances where you find yourself saying, "This doesn't make sense", then it's time to check led signs  power.
