Re: Acer e5-473 no display

I have already asked you what voltages are missing?

Re: Acer e5-473 no display

i dont know where to check because in the schematic i have there is no PL1202,1203 and pu1201

[JaroTech]

Re: Acer e5-473 no display

On page 5, you have all the important voltages. PU1201 and all components for the VGA@ are not on the motherboard because you don't have the Nvidia GPU.

Re: Acer e5-473 no display

thanks for the response jarotech for the pu801 all votages is ok but for pu601 pin1 0v pin2 4.4v pin 345 have 19v and pin 17 has 0v

Re: Acer e5-473 no display

When you measure the voltages, you have to press the power button and then read the voltages, for the PU601 chip, the pins 2,3,4,5 are connected together, you have 4,4V on pin 2? Measure all the pins.
