I had checked the connectors and pins before I wrote, and I was even going to check for continuity on each pin but that's going to take a while and be error prone with 40 pins. The connector on the underside of the DVI has the snap-in latches which are engaging. I can't push any further and I haven't bent any pins. The cable is new from Gregory (Arcade Shopper), so I don't have a lot of reason to suspect it.
Besides trying two different 102s I've also tried batteries and wall power for the 102s, and I even upgraded one to max out the RAM just in case I was missing a memory requirement. The DVI unit itself was pristine on the inside when I first looked at it. I'll have another peek inside to check the connector; perhaps it experienced some trauma and there are broken traces on it. But I really don't want to look for problems where they are unlikely or fix things that are not broken .. I've learned that every time I disturb something there is risk involved. Is there anybody in the Seattle area (northern suburbs) with a known good cable? If I can eliminate the cable as a possibility then there is only the DVI connector, as the rest of it seems to function normally. -Mike On Mon, Nov 18, 2024 at 7:10 AM Royce Taft <[email protected]> wrote: > When I had this issue, it turns out I hadn’t snapped the connector in > fully on the underside of my M100.
