After doing some research, including watching multiple videos from trusted sources, I learned that this kind of flickering is often caused by a loose screen connection or a faulty display cable, rather than a defective screen itself. In some cases, others have reported that RAM issues or a problematic GPU can also lead to similar symptoms.

I believe the issue might be due to an internal hardware connection problem rather than a need for full screen replacement. I’m looking for a proper diagnostic from a trusted or authorized service center to avoid unnecessary costs and ensure the correct issue is addressed.
