Just wondering while I wait for my adapter in the post - I ordered a 40 pin B adapter (Which I assume fixes the issue) and it has a wire coming off it, where do I solder that onto? (I assumed GND but I may be wrong?)
i believe that specified "40 pin B" adapter fixed this issue. and that wire came out is backlight voltage. it works fine even if you don't solder that wire, and if you do it will be brighter than not connect(in my opinion, it is too bright for play long time, but of course it's preference for owner). it should be soldered to one of the leg of "DA1". try search "DA1".
I used a 100k trimpot though, is this a big deal? It seems to work just fine still.
congraturation! thank you for reply. and about the pot, i think it doesn't need to be too much specific. any over 50k will be works fine.
