They are usually a R&R unit (remove and replace) but I have heard of guys fixing small problems in them. You really have to be an electronics guru to figure out what is wrong and if you are not one you would be money ahead to just buy a new/used one. To pay someone to figure out what is wrong with it will cost a quite a bit. If someone out there is fixing them for cheap I also have a dead one.
Well where are the electrical guru's? The one i have is a spare,spare. I picked it up in a trade but it does not work. So who wants to try to figure it out?
Hmmmm, I just cut my spare(working) IDM open to check out modding it, there looks like alot of complicated stuff in there, maybe try spaying it with electrical parts cleaner? Look really careful for anything that looks burnt or melted.
