Hi,
I've got at front of me Lenovo IdeaPad 500S-14ISK
Motherboard: BIV3S LA-D061P REV: 1.0
The issue is that it powers on but has no picture either on the screen or either through HDMI port.
At first glance there is no visual damage on the motherboard, so I've tried flashing bios. That didn't help same result.
Upon closer inspection I have found that I am missing voltage on coils PLI3 & PLI4 near CPU.
So far I've located that voltage does disappear on the PUI2 and it is not shorted to the ground
PIN1=4.94V
PIN2=1.99V
PIN3=4.86V
PIN4=5.065V
Then PIN: 5,6,7,8 = 0V
But I cannot locate any diagrams online, therefore I don't know what it is and what readings we should have there. I will probably put another topic in schematics request.
I hope maybe you will be able to help.
