I just changed my Rytm screen, contrast did not cure the slight fade, and when I opened it what I suspected to be the cause, a slightly warped LCD pcb, turned out to be the case.
Went from this:
To this:
It is supposed to be white on black, but it is more like dark blue, I got it from the ebay seller who has been linked to on the forum before, installation was very easy, but removing the old LCD is very difficult and I would not recommend it to someone without good desoldering skills and all the required tools or you will most likely ruin the main pcb, you need a hot air pencil, electric desoldering iron, some pry tools and a LOT of patience, it took me about 30 minutes to remove the old one, and a minute to fit the new one, but I have a lot of experience of this kind of work. I was thinking of changing my A4 screen as well, but since there is nothing wrong with it and it is difficult to remove the old screen I donât think I will bother. Overall though Iâm happy with the new screen.
