HP Notebook 15s-fq1003na uncontrollable screen flicker on start up. Reboot solves it.

[Ian-A-24]

Hi

To me a loose cable does not seem likely for these two reasons

- it always behaves perfectly once it starts up correctly. 

- the restart or hard reset always corrects it. 100% so far in 3 weeks of use since the problem arose.

In either of these cases a loose cable would surely manifest itself at some point other than start up.

This is not a laptop that has a hard life either - it pretty much stays in the same position on a desk all the time.

Are there any other suggestions please?

I've seen another thread for someone with the same laptop and the same issue
