Salty smell and flickering image

Hi, Don't know about the cap it looks ok but the component behind it R7G2 (just top left of yellow circle) looks decidedly unhealthy. It looks fried, also Q7G2 next to it, bit hard to tell as it is obscured by yellow circle. and perhaps the component above it don't know if it is missing or was never there R7F8

Don't use the PS3 power cable as that it gives out a different type of energy or voltage. This can cause your Xbox to, heat up or overheat. As well as check of all the cables are in place.
