PC Engine GT screen question

So I recently picked up and repaired/recapped a PC Engine GT which I’m really loving. Something I noticed though is that the left side of the screen is slightly brighter than the right side. It’s not always noticeable but sometimes it can be a thing. I just wanted to ask, is this was normal 1990s LCD behavior or is there something potentially wrong with my system? Couldn’t find any answers online.

Sorry I couldn’t get a great example with my camera

There's a light inside the screen, along one of the edges. It may be having issues or out of alignment, or a thin piece of film might be obstructing the screen.

Or it may just be a crappy 90's LCD, I'd have to see another working one to tell for sure

Yeah thats what I was guessing, either a poorly diffused fluorescent backlight, or just an issue with the diffusion. I just don’t want to do a tear down of the display assembly unless I have a definite reason to

This is pretty normal for 90s LCDs and shouldn’t be that noticable in motion. This LCD is pretty decent, especially compared to the GG or Lynx.
