Hello all,
I have this Acer motherboard LA-J871P the issue with this board is that it turns on but does not show any video or post. I measured the voltages of all the coils and all voltages are present except for +VCC_CORE and +VCC_GT. Schematic and board view can be found here at the bottom of the post. This has a dedicated graphics chip on it and that is getting voltage as well.
I checked the driver IC PUZ2, PUZ3, PUZ4, PUZ5 and all have 5V on the ENABLE pin 3. However still no output from +VCC_CORE and +VCC_GT.
Any ideas what the issue might be? Thank you.
