Aqua Illumination SOL Blue problem

[newsalt]

I have 3 SOL Blue LED lights over my 180g aquarium. All three purchased around 2008. Starting today, one of the 3 light modules is blinking. The other 2 are fine. All the lights in the unit come on and then go off constantly. All three units are connected to the same controller. The odd thing is that at a certain time, the blinking lights on the one unit stops and then seems fine. I wonder if it has anything to do with the intensity level of the white, blue, and royal blue. Would anyone have any ideas what the problem might be?

Thanks

Given that the lights are 18 years old, I'm guessing it's simply failing with age. @oreo57 might have a better idea/suggestion.

I always start with the power supply.
Since you have 3 try swapping.
Next would be a short (salt corrosion) somewhere causing the power supply to go into limp mode.

Just a guess though. At 18yrs could be anything.
Also output could easily be down 50%.
