Xbox 360 Repair - False overheating
Xbox 360 S repair that I did recently. Console was turning on; fans were immediately going to 100% and was red dotting. Upon obtaining the secondary error code of 0012 I went to the Xbox 360 repair wiki on consolemods.org and found that one of the causes for this was failed thermal diode resistors related to the GPU. Checked the resistors which were R4D5 and R4D6. They are both meant to be zero ohms but R4D5 was measuring about 11 ohms. Replaced resistor and now console boots fine. This is quite the common problem with these, but nonetheless I thought I would make a post about it anyway.
