I got one of those cables and it was dodgy and the problems lay else where

I think all dmd's are subject to issues at some stage in their life and probably depends on how long they were left on. It's just crap that a whole pin with a big dmd maybe $2k market value and the replacement dmd is $500 after freight = 1/4 of the price of the pin which is just crazy.

Check out the video cavey at the beginning of this thread and that's what the guys are doing with this mod have a monitor to the side / on top with and will be cheaper that a dmd I am sure.
