So, I tested the MOSFETs according to this post on this forum:

Q53, the one with solder under it, measured the following:

Pin 1-2 = 16.2 ohms
Pin 1-3 = 14.6 ohms
Pin 2-3 = 1.8 ohms

Q54 next to it:

Pin 1-2 = 27.5 ohms
Pin 1-3 = 3.6 ohms
Pin 2-3 = 24.9 ohms

According to the MOSFET testing post, these are shorted. I tested identical MOSFETs on other parts of the board and they measured in the Mega Ohms with one pin combo measuring around 30 ohms. So am I safe to assume that these two things absolutely need to be replaced? And am I safe to assume that they are the root cause of the system instability and heat?
