I have a cld-d505 which "someone" plugged into the wrong socket and it blew the fuse. I've replaced the fuse and it still blows. After some research it seems that the transient voltage suppressor diode must be replaced as well and then it will operate again as long as nothing else is blown on the board. I don't even know what one of these things is really. Can i buy just any suppressor diode and replace it or do I need a specific one?
