Hello everyone,
I am reading temperatures above 105C (221F) on mosfets PQL8104 and PQL8103 and the board is operating fine until it goes above 105C and then it shuts down. Cpu is ok.
So can't figure it out. Attached is photo of motherboard, the schematic section showing the culprit mosfets and the whole motherboard schematic. I changed PL8101 thinking it may be bad, same results. I tested out of circuit caps PC8117 and PC8118 and they measure fine.
So I am at a loss to know what else to check to try and identify the source of the problem
Any help would be appreciated.
Many thanks!
