maigre Posted January 17, 2016 Report Share Posted January 17, 2016 Hi ! I am almost done bulding the MB-6582 but i am stuck on LCD wiring and connection. I followed the LCD wiring guide from here: http://www.midibox.org/users/jim_henry/building_a_midibox_lcd_cable.pdf I had a first problem with my initial LCD: the Backlight wiring was not classic and i think i bricked the LCD. So i started with another one, i double-ckecked the pinouts but it still doesn't work: i have weird characters appearing on screen (see attached picture).. Any clue to help me troubleshoot this ? I am trying to resurect an old CORE8 Module to test the LCD, but without success (i posted another thread about this issue). So for now i don't have other to check if it is an LCD issue or MB-6582 issue... Thanks ! Best Regards, Thomas Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted January 17, 2016 Report Share Posted January 17, 2016 Hola! Which LCD model is it? Do you have a link to the datasheet? Imho, it might be an accidentally swapped data wire... you could try rebuilding a new cable, following these instructions: (they are not better than Jin Henrys, just a different approach, maybe it will work like this?) Many greets! Peter Quote Link to comment Share on other sites More sharing options...
maigre Posted June 5, 2016 Author Report Share Posted June 5, 2016 Hi! I bought a new one (a cheap one from Aliexpress, waited loooong time to receive it but it was 2$ + free shipping...) And following your attached guide, i finally worked it thru ! I will replace with a better looking one later, but i am really thrilled it finally display something ! Last step now: link front and back boards.. never been so close ;) Thanks for pointing out the wiring guide ! Best, Thomas 1 Quote Link to comment Share on other sites More sharing options...
