    Another job done - rotten DMD connector replacement... Corrosion has travelled up the wire, notice the blackened copper. Wire cut back a few inches to reveal some half-decent copper to crimp onto: Brand new crimps and housing:

    It turned out that the power supply was causing RAM corruption on power-down so I replaced all of the electrolytics and the IEC mains filter... Old vs new mains filters. An exploded Rifa hiding inside the old filter!! Old electrolytics. New electrolytics. Panasonic and nichicon, no penny pinching here! All done! No more RAM corruption! For now, anyway...🤞
