Hello @Arielavr and @mirkolandia7 

In the simplest case the internal display cable behind the screen is no longer seated correctly. It has come loose slightly.

Recommendation and solution

In your case: Service is required !
- The computer should be disassembled and checked.
- [Always recommended] Thermal paste for CPU GPU and bridges should be renewed
- [Always recommended] The function of the fan(s) must be checked

- The internal display cable that goes from motherboard to screen has to be checked or replaced

- The screen has to checked or replaced

- Short circuit test

- General cleaning ...

HP warranty valid -> Contact HP Support for service repair

HP warranty expired:

If you can't do that, you should have it serviced by a professional notebook (chip level) repair store.

Good luck

Hello @mirkolandia7 and @Arielavr 

This test showed that the GPU (graphics processor unit) is okay.

=> Display cable and/or screen is defective <=

Good luck

it seems more like software problem, because the screen flickering just when its wake up from sleeping mode.

when i turn off the computer and turn on it immediately its ok and there no flickering any more until the next time.

If this is really the case than it's software problem (BIOS <=> graphics / windows / driver )

Good luck
