Hmm... he problem seems worse in safe mode... Has me wondering about RAM - and is it either failing, or at least requires RAM edge connectors cleaning. Or they (if two present) may even be slightly dislodged from their sockets on the motherboard.

Remove all power - battery included.

Open the base of the laptop where the RAM sticks are located.

Remove both sticks (if there are two) - carefully. Clean the edge connectors with a soft pencil style eraser and wipe the edges afterwards with a soft lintless cloth (or even a "soft" tissue). Use nothing even remotely abrasive.

Replace the first stick firmly; then remove it and wipe the edge connector again as above with a soft lintless cloth or tissue..

Re-insert firmly and remove and wipe the edge connector again.

Remove, wipe edge connector as before, and then re-insert the stick firmly and leave it there.

If there is only one stick in the laptop, replace cover and restore power (battery installed too).

Boot up and see if the problem persists. If it does then at least we know within reason that it's not likely an issue with the single stick of RAM being dislodged or having dirty/oxidised edge connectors or similar in its socket. It doesn't rule out RAM fully as it could still be a failing stick.

If there are two sticks, then start with one only as above and do the test as above.

If the problem persists, then having cleaned the second stick as above, remove the first stick and re-insert the second in place of the first. Repeat the re-insertion routine three times (as above).

Restore power and boot up to see if problem persists or not.

If the problem is still present with a second stick in place of the first, (i.e. only that second stick inserted) then likely it's not edge connector issues etc. as mentioned above. If it persists with both sticks it does tend nonetheless to rule out RAM failing; as the chance of both sticks failing at the same time is somewhat remote.

If the problem is present with one of the two sticks inserted and not the other (presuming there are two of course), then one that gives the problem is possibly suspect?

If the problem goes after the first stick (of two) has been cleaned; then re-insert (as above three times) the second one in its slot; reboot etc. and see that all is well.

Again ensure you have removed "all power" when going inside the case.- battery included.

Why the re-insert/remove etc.? To clean the on-board sedge connector sockets. They can oxidise slightly; and sometimes the RAM sticks can dislodge too very slightly. The inert/remove/re-insert routine ensure the sockets are given a reasonably decent clean; and ensures that when you insert the stick(s) you do so firmly.

Again- ensure that all power - battery included - is removed each time yoi go insde the laptop and remove or re-insert RAM sticks.

Hope the above makes sense... OftenRAM contacts can cause all manner of intermittent problems; and display is amongst them... Laptop usually share RAM for display purposes (though some of course have dedicated, separate RAM too), so if there is an issue with RAM then the display may well be affected.

Could be the ribbon cable connectors have loosened a little at one end or other; or that the ribbon cable itself has a break within it.

Gently close the lid to nearly full while watching it. If there is any change on the screen when moving it up and down it is one of the things mentioned in #1 above, most likely the cable itself which fails where the movement takes place.

Always pop back and let us know the outcome - thanks

Moving the screen up and down dose not change anything, only closing the screen for at lest 2 sec.

Long shot...

What happens if you boot into safe mode? Does the problem persist even then?

Can you clarify your #6 a little more please.

What doesn’t come back as you say in your #6?

When in safe mode, if the screen turns white, the only way to get to a usable screen is to reboot.
