Logic Board issue - what’s the damage?

I’ve inherited a not -working MacBook Pro, Retina, early 2015. The previous owner claimed the keyboard didn’t work so the laptop wouldn’t turn on but I’m pretty confident it’s a logic board issue.

I’ve tried disconnecting the battery and connecting to power and I get an orange light on the MagSafe connector with no power on.

Battery charges as it should.

I’ve removed the logic board to check for signs of damage but I’m not overly sure what I’m looking for! I’ve found the attached is the only sign I can see of something out of place. I just wanted to confirm if this would cause the issue of the Mac not powering on and if it’s worth a repair vs replacement?
