Troubleshooting


Lights

  • Electrical
    • Light not working (LED)
    • Check fuses
    • Check voltage at top of VST if none check if none check wall control.
    • Check voltage at top of VST if present check before and after circuit board.
    • If Voltage is not present after board but is before replace board.
    • If voltage is present after board check electrical connections after board and on LEDs.
  • Light not working (halogen)
    • Check Fuses
    • Check input and output voltages on wall control
    • Check connections inside light head
    • If voltage is good on output of wall control check continuity throughout fixture.
  • Camera not working (tvII)
    • Ensure light is on
    • Make sure intensity is turned up (will not work under certain voltage)
    • Check fuses in camera controller.
    • Check for damage on camera, and slip ring. (swap if possible)
    • Check continuity throughout fixture (black wire is camera signal)
    • Swap camera controller if possible.
    • Check slip ring alignment
    • Possible bad camera board
  • Camera not working (tvIII)
    • Ensure light is on
    • Check fuses on wall control
    • Check camera for damage and loose slip ring
    • If camera works but doesn’t rotate and lights are on on controller check motor.
    • If camera works but has no control Check yellow wire (pin 7 on db9)
    • If missing a color check cores of the green, blue and red wires.
    • If camera is flickering and you can stop it by changing intensity on wall control it is possible that 5A board is bad or you have a resistance issue in the fixture itself.
    • If no image check continuity from controller to db9 inside light head.
    • Replace camera board.
  • Light not working partial or full (Nautilus LED)
    • If not fully working check wall control input should be 120. Output should be 18.
    • Check voltage before and after rheostat.
    • If rheostat is good replace power supply
    • If nautilus is partially lit remove top and look for broken wires and loose connections.
  • Mechanical
    • BOM grinding or chattering during movement
      • Inspect bearings under white rubber covers for rust and wear.
      • Inspect shaft that goes into knuckle and re lube bushing inside (spray lube)
      • Remove Support tube clean inside of tube, clean and lube nylon bushing and spring.
      • Any repairs to BOM that require removal of spring need to be sent into Skytron for repair.
  • Radial arm not moving smoothly
    • Inspect Brake screw for damage and tightness.
    • Bearings and races inside of radial arm need replacing
    • Any articulation point not moving smoothly
    • Inspect bearings
    • Look for incorrect hardware (too long) binding bearings
  • Light will not balance.
    • If it is a camera light make sure weight or camera is in light head.
    • Ask if any recent work has been done, make sure BOMs or tops have not been mistakenly been placed on wrong light.
    • If light will not stay up recommend removing small amounts of weight until it will.
    • Recommend replacing spring.
    • If light drifts up and down, remove weight, if that doesn’t work replaces spring.
  • Camera light will not focus with center focus.
    • Ensure user is not trying to use camera to focus light
    • Pin inside light head possibly sheared off
  • User error
    • Rubber cap keeps falling off radial arm
    • Inspect ring under cap and make sure it’s not badly bent.
    • Recommend replacing with nylon cap part number B2-210-58-4
  • Diffusee becoming cloudy or cracking
    • Refer to light cleaners pdf located on skynet in the new lights section under the training and reference heading. You can also refer them to the dispatch cleaner pdf. Located under the same heading.
