Hello everyone!

I followed the archifamous tutorial of how to put an SP frontlight to a Color Game Boy:
http://www.choochoobot.com/builds/gameb … d-001.html

and actually got it to work, but my problem is that although the screen does iluminate, it's impossible to see anything unless there's a light directed to it (just as if there was not a frontlight...). In the dark it's completely impossible to see anything on the screen, although, I repeat, the frontlight DOES light up.
I read that someone had a similar issue and the author of the tutorial suggested to flip the screen. I tried this, but same thing still happens, and actually makes no sense, since I followed the tutorial indications on how to place the screen with the proper facing (although I have not been able yet to figure where is the "Beveled side" that the picture points).

Has anyone had the same issue and found a good solution?
Now that I've written I'll ask something else: The frontlight is quite dirty, not with fingerprints but with residues derived from the unassembly from the SP and a try I gave it with rubbing alcohol. How could I leave it plain clean?

Thank you in advance.
