Here I have this board (E59670) it was in an old monitor I have, it already noticed a swollen capacitor and I am going to replace it, but I also noticed that there is a part of the board that is kinda darker than the whole board, what is it?

It might be due to heat spreading from the large silver heat sink, especially if its position affects the darkening. This could simply be a sign of overheating.

I understand the concern about heat discoloration, though I think it might not be caused by the heatsink below given its position. The presence of jumpers suggests a single-layer PCB. Could you check if anything is visible on the opposite side of the PCB in that spot?
