Yellow LCD tint

I have an issue where the top right hand of the LCD has a yellow tint to it:

I searched on the forum and there was another report that was answered by saying that there are through connections on the PCB which haven't been trimmed down. I have dismantled but I can see any on the ethernet port that seem to be massively high:

Does anything on this screen seem like it needs trimming down? There is only one pin on the ethernet connector that looks slightly high and then some on the USB ports.

Thanks in advance for your advice.

You can try to trim more the pins that seems the highest. Also check the USB pins too. The big plastic pins can also be trimmed.

Also you can maybe try to replace the small black foam with one that is less thick. The main point of that foam is to insulate so that the pins do not contact on LCD metal case.

Another thing to check is that the LCD is correctly fitted inside it's cavity. Make sure it's well in place.
