After Screen replace ment, screen blank, backlight on

What Happened: I was replacing a cracked iPad Mini screen following multiple instructions I had found online. None of which had stated to disconnect the battery unfortunately. After which when I power up the unit the screen remains blank. I can confirm that the back light is on, so it doesn't sound like the same fuse as the people who've lost their back light.

Tried: I tried reattaching the old cracked screen to see if it was a problem caused by the new screen. I tried leaving the battery disconnected for an extended period of time and then reconnecting everything. Neither worked for me.

My Experience: I'm just a hobbyist in these repairs, I haven't worked on an iPad before, but have replaced iPhone screens and worked on other devices. So if it's something too intricate, and someone wants to quote me a price to fix this. Please do.

Thanks in advance for your help.

You're right that the image circuit is separate from the backlight circuit. Most likely causes here are:

Some slight pry damage near the connectors---look at the board under magnification.

or

Damage to a component that is very near the EMI shield bracket --I've seen before where someone poked around investigating the backlight fuse and shorted this component. With the battery disconnected, remove the EMI shield that covers the backlight fuse area and look for any burned or damaged components.

Sorry it took me so long to get back to this. So i pulled off the EMI shield and looked at everything through a x5 magnification. The fuses and the connector. I even looked at the connector on the screen. I saw no signs of anything blown or damaged. Do you think I should try a new LCD?

Yes, you do need to rule out bad LCD. Make sure to pull the black sticker from around the connectors in your search for damage
