CPUGT_GLx pins are not connected; so no matters the voltage there.
Pin 12 should have PWM signal; but ONLY when the chip receives that signal.
"Pins 12 on U7410 = 0.08 volts, but when I check pin 12 on U7100 this shows 2.4 volts"
Did you check the continuity?
As you found corrosion signs on graphics area, this should confirm iGPU damage.
You can put quality flux and heat CPU; before trashing the board...Leave a comment:
