It's just dead. Very little heat.
So this was my xbox that I used almost every day before it broke. It said e74, so I reflowed HANA. didn't work, reflowed gpu. It worked. So I put thermal paste and put heatsink a back on, shows 0020, fixed that, then 0031. Reflowed southbridge and now it is dead. I only get a tiny bit of heat from the standby mosfets, they are giving normal voltages. What should I test?
