What is this component (please login to see attached picture) ? It might come from an LCD screen or a printer. I can't find any reference on the Web. It has four pins in a row. One is "+", another one is "-".

Full wave bridge rectifier to be more precise.
I found something like this in a friend's dead meat slicer. Nice thing to have if you just want to run a small DC motor off AC input. But it ended up being the fuse holder broke and the fuse fell out. After bypassing the fuse the slicer was revived!
