Hello all, I have big problems with my Gamebuino screen, I don't know if others had them and managed to fix them.
First off, I need to say that I carefully read the wiki (getting started, and troubleshooting) but to no avail.
The physical connection of my screen to the pcb is originally very bad: I have to operate the Gamebuino without the back case, and with a sim-card acting as a lever in the top left opening where the screen is snapped to be able to see anything.
Not doing that, my screen is 100% blank all the time in all screens (bootloader title, game grid, or in any game).
Doing that though is sometimes not enough, and that's the purpose of my question:
Most fixed screens, typically title screens (bootloader or games), have a good contrast and display perfectly. But as soon as there is an animation, some horizontal lines appear lighter than the rest, and a little flickering, in other words they look like painted in the third (gray) color I read in some topics of this forum.
But that's not the worse: in screens full of text with zero animation (e.g. my gamebook engine) using font5x7 the display is as perfect as the title screen: I can see deeply contrasted black pixels. Using font3x5 it is still readable, but the contrast is not so good: there's a little flickering and the whole text on screen looks grayish...
Finally using font3x3 the whole screen is totally unreadable! tilting the Gamebuino so that my eyes do an angle of a few degrees with the screen plan, I can hardly see that the screen is filled with (almost white) characters, but in normal reading conditions the screen appears empty >_<
Do these symptoms ring a bell to anyone ? Is the problem known and fixable ?
Few final words: I also tried to change the contrast / backlight settings but that didn't change anything. I also thought the light sensor could be the cause of the blank display so I tried different configurations: covered, in shadow, under deep light but alas again to no avail. And I also thought the battery was causing trouble so I recharged it at 100% (until the most right led was on), all for the same results.
Thanks for any feedback !
