Hey chipmusic forum, I'm hoping you guys could help me out on a problem I'm having with my Gameboy DMG. I couldn't find any other place to get a public input. I figured since everyone here is very knowledgeable on the subject I would get the best help.
So anyway, I just recently did the backlight biversion mod on my old Gameboy with the kit and inversion chip on this site, http://www.handheldlegend.com/.(sorry if they may be a competitor, I have no clue who's associated with who). I made sure to be extra careful with everything and it worked out beautifully. I put in the white backlight and inverting the display twice made it so much better.
Recently I've noticed that when I'm playing a game that if I play with the contrast and make it lighter I can see horizontal very very faint dark lines. When playing a game you really don't notice it one bit unless you try your hardest to see them. I figured out that these lines are caused by powering on and off the system. You usually see 1 bright line across the screen. This also would happen without ever modding the handheld on everyones. It seems like in this case it's burning it into the screen?
So my biggest question is that if this is a normal occurrence and if I shouldn't worry? Do I have screen and power issues? I did everything by the book correctly. I noticed this morning that a lot of the lines from last night disappeared, but some still remained. Wondering if the screen just needs some rest to disappear.
BTW, I'm also playing one of those Chinese bootleg multi carts with all the Pokemon games on it. Any thoughts if that is somehow affecting the situation?
Thank you in advance for your help. It is much appreciated.
