Screen gone blank, only a few vertical lines visible
I got this laptop repaired a few months ago. It was working fine, the repair changed pair of fans, thermal system and lcd. After a few months suddenly the screen got blank and only a few vertical lines are visible while turning it on, which eventually goes away. Can someone help fix it
