Ram tests OK

the display test cycles through everything except those two columns and one line that dont come on

I think something is looses somewhere, but what?

I reseated the ones on the board and the DMD, its the first thing i tried

Firstly, thank yuou for all your input, i apreciate and value it

I reseated everything and now the bottom line works but not the two far right ones, which leads me to think it is indeed a loose something someplace, or the ribbon cable is damaged some how, i recall having a ribbon cable problem back in the day with computers. Any ideas who would sell ribbon cables or would i have to make my own from some old ones i still have sealed for computers

thanks

FYI I redrew these to vector for a keyring
