duncanflight Posted July 10, 2012 Share Posted July 10, 2012 One of my JB A7 zoom LED fixtures doesnt want to power up. You used to have to remove and replace the fuse to start it up but now nothing happens. Thanks Duncan Link to comment Share on other sites More sharing options...

duncanflight Posted July 10, 2012 Author Share Posted July 10, 2012 I have a fairly good understanding of electronics and wiring. I'm used to fixing sound gear and generic / intelligent lighting fixtures. Can solder and have a well stocked workshop. But moving LED fixtures are new to me? Any suggestions!

Brian Posted July 10, 2012 Share Posted July 10, 2012 First thought, given the stated history, is a duff fuseholder. Link to comment Share on other sites More sharing options...
timsabre Posted July 10, 2012 Share Posted July 10, 2012 First thought, given the stated history, is a duff fuseholder. Or it could be a failed internal fuse on the switch mode power module, or the thermistor on the module which limits the inrush, if the input supply fuseholder has been intermittent.
