Retronaut: Repairing Extremely Dim Amiga 4000 Video

129

Retronaut’s Amiga 4000 developed a very dim display during the recording of his recent video on the Fastlane Z3 SCSI/Memory card. A day after the video was released, the Amiga 4000’s display brightness dropped to approximately 5% of its normal level and required immediate attention.

Follow Retronaut as he investigates the potential causes of the issue. Could it be a failing monitor, a problem with the LISA graphics chip, faulty resistors between the video DAC, or the DAC itself? Watch to see how the troubleshooting unfolds.
