Hi, I have the well-known issue whereby the internal screen doesn't turn on. No acer/predator logo either.

Laptop Model:
Acer Predator Helios 300 PH317-51-50K2
i5-7300HQ, 8gb ram, GTX 1050 ti

- It does work fine on an external HDMI screen
- Internal screen doesn't seem to turn on at all, no predator logo, no bios access (doesnt seem to work externally), no backlight turns on
- re-flashed the bios (v1.21)
- keyboard does light up when turning it on
- Tried re-inserting ram
- Tried pressing the battery pin on the bottom, no effect
- Reset windows, stays the same
- checked screen cable, everything seems to be fine internally

What can I do?

Hope someone knows a solution to this

Thanks

  • Have you tried to press fn + f5 and fn + f6? Also, when you use a flashlight on the display, do the windows icons appear? Have you checked the edp cable on the motherboard and monitor?

    I did try fn+f5 (win+p) and fn+f6, no result.
    I tried with my phone's flashlight to see if there's any icons, as far as I can tell it's completely black, no image appears.

    The cable on the motherboard has been checked, its attached properly.
    The other end in the screen is untouched.
  • Is your notebook under warranty?

    Not anymore.
    I also opened up the laptop completely (including the screen bezel) and checked if everything was connected firmly; and it was.
    For now, we're using it with an external screen but it's still a bummer.
  • Do you have how to test the display and the edp cable on another computer?
