Predator PH315-51 Screen lines flickering, how to fix it or how/where do i replace the screen?

AlohaBoom

Hi community,

My Predator PH315-51 laptop is having the issue shown in the video, it started a few months back and was no big deal at the moment because these sort of flickering (don't really know how to even call it) was just taking the bottom part of the screen almost unnoticeable, but now it is eating the entire task bar and seems to expand every week, there wasn't any event when this started, i just remember upgrading from windows 10 to 11 but can't tell if that triggered this issue. Any ideas on why this happened? A way to fix it? or some guidance to get the screen replacement or the part that's causing the issue? Besides this screen problem that laptop works perfect, if i plug other monitors there is no problem in them, is just the laptop screen.

We need to determine whether it is a hardware or software issue..  Turn off the computer.  Tap f2 key while turning on the computer.  It will go to bios.  Please stay on the bios screen for 30 mins.  If the display is looking good on bios then it is a software issue.  If the display is not looking good on the bios screen then it is a hardware issue.  

 

If it is a software issue try the following the steps..

Try windows x 

go to device manager 

expand display adapter

right click on display driver - uninstall 

Restart the computer 

It should work fine.. 

If it is still not working 

Uninstall the display adapter from device manager 

Dont restart the computer. 

Go to support.acer.com 

chose your country 

type snid or chose your model 

go to drivers 

Install the display driver 

It should work fine..

If it is still not working then we have to do a refresh and reset

If you dont wish to do a reset you can go back to windows 10.

If you wish to do a reset ..

click on start - settings - update and security - recovery - reset this pc - get started 

or 

on start - type here to search - type reset this pc - click on reset this pc on the top - click on get started 

It will show you keep my files and remove everything

chose keep my files 

chose the account - type the password - click on local reinstall - click on reset 

It will be in progress.. 

login to computer and start using the computer. 

If it is still not working 

click on start - settings - update and security - recovery - reset this pc - get started 

chose remove everything 

click on local reinstall - just remove my files - click on reset

It will be in progress

Note:

If you do refresh ( keep my files ) - all your personal files like pictures, music , documents , videos will still be intact.  Only the applications will be lost

If you do reset ( remove everything ) - you are doing a factory default.  It will become like a day one computer.  It will wipe out everything and take your computer to day one like a new computer. 

You can also do the recovery in an alternative way..

There are two alt keys on the keyboard. If you look at the bottom row of keyboard you can see the one on the left side of space bar and the other on the right side of space bar. The alt key on the right side will be looking like alt, alt gr or alt car. Turn off the computer. Hold the alt key on the left and tap f10 continuously.  It will go to repair mode. It will show you chose an option, continue, troubleshoot.  If it is not going to repair mode, turn off the computer. Turn on the computer. Hold the right alt key ( alt gr or alt car or alt ) and then tap f10 continuously. It will go to chose an option continue and troubleshoot..

It will show you chose an option, continue, troubleshoot

Go to troubleshoot - click on reset this pc

click on keep my files ( only applications will be lost )  chose your account and type your password  - click on local reinstall - click on reset

It will be in progress 

If the keep my files option is not working 

Go to troubleshoot - click on reset this pc – click on remove everything – click on local reinstall – just remove my files – click on reset 

It will reinstall windows. 

If the just remove my files is not working.. 

Go to troubleshoot - click on reset this pc – click on remove everything – click on local reinstall – Fully clean the drive – click on reset 

It will reinstall windows. 

Note: You can also go to chose an option , continue , troubleshoot by holding the alt key + tapping f10 or alt gr + tapping f10 on the keyboard while turning on the computer.  Once you see the troubleshoot option, you can stop tapping the f10 and stop holding the alt key.  Then you can try the keep my files and remove everything ( just remove by files and fully clean the drive ) by following the steps which was mentioned above. 

If it is still not working after reinstalling windows then you have to go back to windows 10.

Thanks for your help, as per your first suggestion i checked in the bios, it seems it is a hardware issues, do you have any guidance on how to proceed in this case?

It looks like a hardware issue since the display is not looking good in bios.

Just to double check the issue, let us do two more steps.

It might also be the issue with battery, charger or power outlet.  Try to use the charger in a different room on a different power outlet. Try to bypass the surge protector and connect it directly to power outlet.  Try to use an alternative charger if possible.  Try to turn on the computer without the charger and check it ( as long as the battery is not drained out )  

Try to check it in bios again.. If the display is not looking good in bios then it is a hardware issue.

I am really sorry for the inconvenience..  Let us do the basic steps first..

Doing the power drain and bios defaults will really help. Kindly follow the steps given below:

Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down. On the bottom of the laptop, you can find a pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and – sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer. Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.

If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery. Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down. On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door. Just below that you can find a latch. If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 

 

If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop.  Hold the power button for 1 minute. After releasing the button you should wait a while before plugging in power. Just because the button has been pressed doesn’t bleed off all the residual electricity on the motherboard. Wait 15-30 minutes before plugging in power. Then once power is connected wait for a full battery indication before turning the system on. That allows the battery to fully reset it’s internal statistics.

Connect all the cables back and restart the computer.  

While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear. Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.  

 

Turn off the comptuer.

Try to check it in bios again.. If the display is not looking good in bios then it is a hardware issue.
