hi all- i have a DMD on a frankenstein that threw a line out some months back-the fault never changed,the same as my WW that still begs for a new DMD when i get round to it....the thing is the display went completely black so i thought it was shot....until i took the DMD off the pin and checked all the plugs and re seated the 5v power plug...which is pretty loose ...powered up again and the line was no more!! switched on and off several times and all was good?? and still is..am i wrong to think that once a DMD has a line out it stays out..how the .... can it make good again? thanks Adam
