I just bought 2 EMu Proteus 2000's on eBay from the same person, and it's like the contrast is turned all the way up on the display, so that the text rectangles for each letter are all the way dark. I can barely read it at any angle. I've tried adjusting the screen view angle, but that doesn't do much. It just helps me barely be able read the screen from a very narrow angle. It's just really strange that both are doing the exact same thing. I don't see a contrast adjustment on here.
If I were able to adjust contrast, that would probably fix the problem. Am I missing something? I also did a factory reset and that did nothing. I opened the top, and I don't see any internal pot to adjust the contrast. Has anyone seen a problem like this before?
