Question Laptop screen won't stop flickering.

Oct 22, 2019
Okay, so a little bit of background.
I've been having problems with my laptop screen flickering for a while after startup for some time. A bit after it's turned on(specifically the screen) , it would start flickering with a lot of red mirroring of the image on the screen for several seconds, up to a minute or 2, and afterwards, the screen would have a greenish tint in one corner and sort of scanlines over red coloured things on the screen. It has happened a few times, and persisted for weeks, but went to working perfectly normal after this, for months/weeks at a time.
This time however, the scanlines appear immediately upon being turned on, and when the flickering starts, it won't stop, tried leaving it on for a few hours to no avail.
Moving the screen doesn't affect this is any way, nor does it affect another monitor that's plugged in. (though it does ocassionally show a faint different looking flicker, I think this is unrelated)

i'VE tried updating and reinstalling drivers, as well as powering the screen off for a few hours, neither seem to have had much of an effect. Except for the screen powering off stopping the flicker for about a minute or 2.
This started happening on this scale with the latest windows update, but that could be a coincidence.

Here is video of it

Sounds like either your display cable is loose/damaged and needs replacing or the display itself is going bad.

To check for sure if it is them and not your GPU (less likely) try the following...

  1. Turn the laptop off (not sleep or hibernate but off).
  2. Connect an external monitor to the laptop.
  3. Turn on the external monitor.
  4. Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

NOTE: If the laptop is under warranty, don't open it up or use a local tech. Instead contact the manufacturer. If not under warranty, then who does the work is up to you.
