Sreen lights up but shows nothing

I transferred the logic board of my IPhone 8Plus and all of its components into a new housing, and after wards when rebooting the phone i found that the phone would still technically work as in you can still touch it to do things like answer calls buuut you could not see a thing its really just huge guessing game of what you’re pressing when the phone is on. I took the phone to best buy where the examined everything and told me the logic board was fine so they would attempt to replace the screen, sadly 10 minutes later the man returns to me with the news that the screen replacement didn’t change anything. what should i be looking for in terms of repair here? Another screen is obvious seeing as i more than likely damaged the other on in the transfer process but is there anything else i should look for to be sure it will work the way it is supposed to?

It’s very important to always disconnect the battery before disconnecting/reconnecting the screen assembly. The issue is that the LCD connector has pins that have high voltages (i.e. the backlight is ~20V) and ground in very close proximity. When you fumble around trying to line up the connector plug to the receptacle, you can short out the voltage rail and cause damage to the components in the backlight circuit. If you’re lucky, then only a backlight filter is damaged but other times, the entire circuit could be affected. Either way, this type of repair requires micro-soldering and isn’t really a DIY repair.

To test for this, plug your device into a charger or an iTunes enabled computer. Then shine a bright flashlight on the screen. If you can see a dim image, then the backlight circuit has been damaged. If you can’t see an image at all, then it may be the LCD circuit that is damaged.

You can connect the original, cracked screen to confirm this. If the original screen has the backlight on, then the replacement screen has an issue. If the original screen also doesn't show the backlight, then the backlight circuit is blown.

I think the logic board is the problem here. Specifically the connector for the screen. I would examine the connector on the logic board for visible damage, also check for lint or any type of debris on the connector. I think the logic board is the problem because you have two screens exibiting the same exact issue. Someone probably knows better than me though
