ASUS TUF Gaming A16 Advantage FA617NTR-N3010W – Powers up, no display.

Hi everyone, my first post here.

When pressing the power button, laptop starts, fans spin at fast speed, keyboard backlight illuminates but have no display on screen, no screen backlight. Laptop restarts after exactly 1 minute. Stays on for exactly 1 minute then shuts down for 15 seconds, then powers up and stays on. Nothing on screen. Caps lock light does not illuminate when pressed. Keyboard seems to be unresponsive, other than the power button. Have to hold power button down to force shutdown. Connect external monitor via HDMI, no display. The issues occur whether charger is connected or not. Disconnected battery, removed RAM and SSD, but same issue.

Have checked coil voltages and resistance to ground, see attached image. All of the coils which are in a row above the CPU and GPU have a voltage which is fluctuating between 0 and 0.02V.


Identification number on motherboard is FA617-PMV-GBM 6050A3460902-MB-A02.

Would like to check the VRM controller to see if it is getting a VR_ON signal from the EC chip, but can’t find a datasheet anywhere.
The chip just above and to the right of the CPU is numbered MPS2328 MP2845A R5602798X. The chip just above and to the left of the GPU is numbered ISL69247 IRZ W348B2U. Photo’s of both chips are attached.



Any help and advice you can give would be greatly appreciated.

Hello. I would try to reprogram BIOS. You can prepare it yourself using the EZ Flash file on Asus site or try to use dump from the internet. Do not forget to save the original dump, as this is crucial to copying DMI data from original BIOS to the one You will program. Also post the motherboard marking as it is missing.

Measure the voltages on all the coils when the laptop is left on for a longer period of time.

Hello. The BIOS chip (Winbond 25R256JWEQ) on this board is a WSON-8 8x6mm size. Unfortunately, I don't have an adapter for this type of chip. I have ordered one, just waiting for it to arrive. As soon as I get the adapter, I will de-solder the chip and try to reprogram.
There is another Winbond chip on this board, it is a 25Q16JVSIQ. I'm not sure what this is, maybe a second BIOS? I've attached a photo showing both chips.

The marking of the motherboard is in the first post.

I have measured the coil voltages after the laptop has been on for 30 minutes. There is no change. I have discovered that the voltage fluctuation on the CPU and GPU coils was my fault. I wasn't making a good contact with the multimeter probe. They all measure exactly 0V.
