So my chaotic desk bit me pretty hard in the back side yesterday. I was testing a custom ribbon cable adapter to run my own LCD from the FW eDP output - it was the third iteration (after two stupid design mistakes) and it worked, yay!
Then the computer stopped booting. Proceeded to begin unplugging everything but couldn't get it going. Fans not spinning up. Post codes reports fans not responding and CPU not reaching power state 0. I do get power to connected USB devices, and I do get lights.
I then find a small bit of unused solder under the mainboard, and then I find a small scorch mark next to a (I think) capacitor on the board - so I'm guessing I caused a short.
I have a ticket open with FW at the moment to see what they think, but I have no idea if they do board-level repair.
So really just opening up a topic here to see how much I screwed the pooch on this one. Is there any chance the damage is going to be localised to the components where it looks like the damage was done? I have had a look over the rest of the board and cant see anything that immediately looks 'bad'. Or is it pretty likely this has fried something further down the line?
If by any chance replacing the cap in question might fix it I could have a crack at this myself (assuming I have an otherwise dead board). I could have a look for someone with more expertise than myself to take a look at it or I can just accept the loss, sell it on eBay for parts and replace.
Here is an image of the region near the solder piece I found, showing the potentially damaged cap (if it is indeed a cap, I'm far from an expert)
