Appreciate this is straying from the console light somewhat but was wondering if I could pick your brain... I picked up a non-working router thinking it was just a NOR flash replacement, but it seems there's a bigger problem on the board somewhere. The NOR chip was indeed toast (unable to read it on or off the board), so I've replaced that but I'm still at a loss as to why it won't power up.
Thinking if the NOR chip was cooked then it might have taken a jolt, but before I call it I was wondering if you could suggest any other avenues for diagnosis. This is the board: https://imgur.com/a/hFUAnxg, I can read 12V at the lower left of the board in the first pic at the socket, diode and at various resistors so I know the board is getting power.
I assume something has shorted to ground, but don't have a clue how to start picking that apart.
Cheers in advance!
You got a multimeter? First thing to check is go either side of the coil in red checking for continuity to ground. Next up have a look at that blue area, the top right pin looks like a cold joint. Not sure what that is for but start there. There is also a fuse (or is it a resistor) on the output of the dc jack, just check there isn't a ton of resistance through that. I can't imagine there would be as being a router id imagine its probably something like 0.5amp or something small If it is a fuse, cant tell as pic is a bit blurry there.
