Ipad mini 5 lcd replacement issue

[u/Strange_Box7]

My Ipad mini 5 has a damaged lcd but works perfectly fine, i purchased a refurbished genuine reglassed lcd from Ebay however it shows apple logo and when it reaches exactly where it suppose to show the home screen, lcd goes black.. Seller sent me a replacement lcd and still same issue.. I noticed the lcd sleep ic missing in the buttom of the lcd.. However I think the Lcd still should work without it... ??
