Question Does dead laptop battery affects lcd screen?

[kenth villa]

My laptop battery is dead and not charging for a couple of months and I know its dead, so I leave it attached because it is not detachable. But after a couple of months it charge again but slowly make my lcd screen blinking, but the blinking will fade and lcd display normal again. But weeks after the battery charging again the whole lcd display white screen even in booting, but it will display in external monitor so graphics card is ok. My question is ,does the battery is the cause of the lcd display failure?Because, I'm planning to replace the lcd and I want to know first if the battery is the cause of the display failure to prevent the new lcd to be affected again.
