I had a mostly working eMate that needed a hinge repair and was not recognizing touch events. I rebuilt the hinges and replaced the screen cable. Everything is back to working order -- except that I hear a hum when I turn on the backlight. I don't recall hearing it before.
Does anyone have an idea of what it may be? I think the re-soldering was good but maybe it's something I did?
