Nikon F4 DP-20 Standard Prism Viewfinder Problem

[S_Ples.]

Hello there. I am Spiros from Greece and I own since December 2015 a Nikon F4 analog camera. A couple of days ago I realised that I had a weird spot inside my viewfinder display. It seems to be a spot at the LCD illumination window (finder side) and as you see in the picture attached it is between the shutter speed indicator and the over&under exposure level indicator. Is anyone familiar with this problem and if so can you provide me with information concerning the repair. Thank you in advance!

It's LCD bleed. Apparently, it's common on F4 cameras. The same thing appeared recently in the frame counter LCD window on my F4S.

Thank you! As I found out after some web research about LCD bleeds on F4 cameras it is indeed a common problem.
