It could be either the processor or piece of RAM failing or more commonly a crack/break with a solder ball(s) used for electrically connecting the many contacts to the PCB.
You could try heating the area with a hairdryer to see if it makes any difference to the image.

If after using the hairdryer you see a positive change then you can go for a reflow with the heat gun, add flux around the processor and raise the heat to about 230c over about 3 minutes. Going over about 250c will cause permanent damage.

Someone may yet chime in here with a good reason why it's one board/component or the other but I won't be able to help you further in that regard.
