Has the phone's [link|https://www.samsung.com/us/support/troubleshooting/TSG01001077/|LDI] changed colour to red? If so then there may be more damage than what is obvious to the eye.
Did you disconnect, check (and clean) the display flex cable end and associated systemboard connector in case water got in there? Also the water may have got under any shields that are covering some components. Best cleaned using Isoproyl Alcohol 99%+. Also make sure that when cleaning that the battery is disconnected from the systemboard, until the alcohol has fully evaporated.
Here's the ''No Display'' troubleshooting flowchart from the service manual that may help. Also images (both enlarged and normal size) showing the location of some of the components shown in the flowchart

Here's a [link|https://www.youtube.com/watch?v=_nRe-PYexmk|teardown video] that may help.
It looks like the LDI #1 marked in your image is a spacer of some kind because at 3:00 minutes into the video it is seen and it is the same colour as shown in your image.
As the LDI#2 in your image, near the SIM reader (also seen at 3 minutes into the video), appears to be OK, water didn't enter through that way but this doesn't mean that it didn't get in anywhere else.
The cable ends shown in the other image you posted may be corroded or it could just be the camera angle and the light but looking at 3:39 minutes into the video they seem very bright and silvery.
I would check the cable connector underside (not shown in your image) and also the systemboard connector for the cable to see if the pins look corroded or not.

As for U5002, no doubt you'll need microsoldering experience and tools if you need to replace it. Unfortunately the service manual I have has no parts list so hopefully some info is printed on U5002 to help identify exactly what it is.
