any vid with fan not working? mine is not switching on, did replace the fan with a Noctua but light just doesn't turn on or new, did test the fan and it works with just on off but not in the light.. Kessil A360W is the model
Overheating would be the first suspect (clogged heatsink, fan not at full speed, etc.). From there: many potential problems. LED channel circuit failing, power circuit failing, etc.
