Please find the attached video link, I don't know why it is flickering intermediately. Did anybody faced this issue ?
I have checked with external screen but I can't see flickering in the external monitor but the internal one is flickering.

Forgot to tell, I was changed the battery, did I screwed the display because of pressure on it?

Looks like screen problem.

It is not happening always, it's happening when I keep it long time in cupboard. Something related to temperature I think. Will display performance impact depends on temperature? Yesterday whole night laptop was outside and it was ON. Today I don't see this flickering anymore
