I’m guessing that based upon some previous posts that is the lcd gets past the ‘connecting’ prompt that the Ethernet controller has initialized? Sooooo maybe something wrong with the clock signal? hehe
That’s correct. If it can get past the ‘connecting’ screen, that means the Ethernet controller can initialize successfully. The LEDs on the Ethernet jack not lighting up is definitely an issue — the green light should light up, and the orange light should blink occasionally.
About the continuity testing: the RJ45 jack is an isolated type (it has internal transformers): that means the PCB pins are not connected directly to the Ethernet cable wires.
Any new findings? I’ve seen one previous case where the 25MHz crystal (for Ethernet controller) is defective. This is very rare, but it’s a non-zero chance.
