Brilliantly clear and simple to follow. As I suspected it was the inverter board that failed leaving me a totally black screen on my 20 year old 22 inch Cinema display (ADC). Your guide enabled me to restore the monitor to working order, and it’s now paired once again with my Apple cube. Thank you ever so much!
