Grafix RA-GRX-6 issue

I have a RA-GRX-6 that controls three types of lights in a home theater. It has worked flawlesly for the 13 years I have ben in the house. oday I went down to turn on the lights and I am getting a bad strobing/flickering when i turn the lighst on and when i raise them up and own. Also a slight flicker when they are at max.

Is it toast or can it be saved?

Has anything changed in the system? Different bulbs? New LEDs?

Grafik Eyes only do forward phase dimming. It will be a challenge to find compatible LEDs for units from that ERA.

You could try and turn 1 zone at at time on and see if it is a single zone.
