All functions are normal or suddenly turned off. Is something a proble Logic board visual inspection is normal There are no other problems and the CPU temperature is very high. I think the CPU temperature is high. SHORT on CPU side? Where should I check? I checked several component In the sound test mode, the resistance value is measured, but is it normal if no sound is heard?
Your PPVDD_CPU & PPVDD_GPU appear low to me. They should measure 1.1V. If they are measuring lower, then it is indicative of the PMIC (which supplies the those rails) going into current limiting mode. I would insect al of the bypass capacitors on those line to see if there isn’t a problem. Sometimes there are tiny solder balls that can short neighbouring components and cause partial shorts.
