Amiga 4000:  Repairing Extremely Dim Video (http://"https://youtu.be/O4BfnvdcFYc")

My Amiga 4000 developed a VERY dim display during the recording of my recent video on the Fastlane Z3 SCSI/Memory card.
A day after that video dropped, my Amiga 4000s display was down to maybe 5% of its normal brightness and HAD to be fixed.

Follow me, as I work through all of the candidates that could cause the problem. Was it simply a monitor on its way out? Or the LISA graphics chip?
Maybe resistors between the video DAC or the DAC itself is where the problem lay?Watch and see how things shake out.
