How are the M100¹s powered? AC or battery? The DVI box relies on the +5V from the M100 to enable the interface without that nothing will happen. You might want to check that both M100¹s are providing a good +5V at pins 1 and 40 on the IC Bus socket. Even though the M100¹s are working they can work down to about 4.5V or slightly less.
Do you know if the DVIs boxes were working when they were purchased? The other bad possibility is that both DVI bus interfaces are dead :( It is the weakest link in the chain and they might of both died, on two units it should be very unlikely. However there is an electrolytic cap on the DVI interface board that connects to the +5V from the M100. It could of leaked and now be pulling the +5V down just enough to prevent the DVI interface buffers enabling. The rest of the unit would not be affected at all by this problem. Do you notice any changes on the M100 when it is plugged into the DVI? Sometimes when the +5V is getting loaded you can hear a whine from the on board power transformer as it struggles to supply power - at least on my M100 :-D On 17/2/18, 8:24 AM, "M100 on behalf of Randall Kindig" <[email protected] on behalf of [email protected]> wrote: >Ok, I¹m at my wit¹s end here.
