This posting is for an ADJ (American DJ) Profile Panel RGB, typically used for wash/stage lighting in live performance settings. It had been purchased new in 2017 and worked flawlessly since then, but had recently developed problems power cycling. The light does not turn on when connected to power, but would "flicker" when tapped on. It's possible there's a loose solder joint somewhere in the electronics. Can include a power cord and user manual upon request.
Please feel free to contact me anytime with questions or interest. Thanks so much for looking!
