Windows 10: Flashing Screen, HP Laptop

I’ve a friend with an HP laptop Windows 10, about 18 months old, with a flashing screen problem that started before Xmas. Can’t see any software installed around that date and running Taskmaster, the flashing continues Internet says this indicates not a software problem.

Opened Device Manager in safe mode, uninstalled the display monitor Intel UHD Graphics 620 and rebooted: loaded a driver and flashing continued. Tried update, it said already latest version. Windows Updates is turned on and up to date but System Restore unfortunately is turned off and Microsoft trouble-shooter hasn’t identified any problem.


Tried Command Prompt as Administrator then the following fixes: -
sfc /scannow
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
but all ran without finding any error.


Screen resolution is set to 1920 x 1080 and 60Hz refresh rate. Tried changing the refresh rate to 40Hz but no improvement.


In Safe Mode/Minimal the flashing stops but Safe Mode/Active Directory Repair and the flashing continues.

Assuming I identify the service or services causing the problem switch off additional services one by one until the flashing stops will I be able to download and replace the service? I’ve had problems in the past with corrupt files in use by the operating system not allowing any changes to be made to them.

I’ve noticed that moving the laptop lid towards the almost closed position increases the flashing.
Are there any other fixes that could perhaps resolve the problem or is it back to factory settings?

Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd

 

Hp laptop screen won’t display except occasionally

- this suggests BIOS corruption or a hardware problem...
Whilst you might try flashing the BIOS (updating it may be necessary to run Win 10- witness your problem above), you also say you have access to it.
Do you hear any beeps or sounds?

Try steps 1,2 here:

Check the version of your BIOS vs that listed on HP's site for your laptop.

I'm also wondering if this might be related to your CMOS battery inside your laptop. (This should be a normal circular battery).
How to replace the CMOS battery
- but that's just a thought.

Worth asking on the HP forum.

================================
Sorry that's not how to create a bootable disk. All that disk is is data storage- as you just copied the files to it.

Please see:
How to Create a Bootable DOS USB Drive
for one way to do it using a free program.

However, given the above, doing that isn't likely to help you I'm afraid.

 

HP Laptop flashing screen

Good day to all.
I have a HP laptop running the uptown date windows 10.
Nine times out of ten then I connect an external drive to the USB port I get a browny colour flash on the screen and also when removing.
Have checked all the latest HP updates from the HP website but no luck.
Does any one know what can cause issue its really annoying.
Thanks
David.
