 |
|
My DMD likes to go down to a single line across the display from time to time. if you knock on the display it will return to normal. any idea where i should start on this? i reseated all the connectors and pushed in the idc connectors on some that seemed not seated as well as they should be.
my next thing is to see if i have some cold solder joints but does anyone know where i should start? what cable would cause the display to go to one line. My first guess is it has to be the data cable since obviously i have power to the display. but does the display info come from just the cpu board?

| Cold solder joints first, especially the big connector. Try a different DMD after that, or a different ribbon cable. |

Lloyd. is that the big ribbon connector from the power driver?

Big connector is prone to the pins coming off the DMD having broken solder joints. Not the ribbon cable.
Sorry for the confusion, I thought by big connector would differentiate it from the ribbon cable. |
