Hey Binh, I ended up gluing the whole thing together with double sided carpet's tape so no go on dis-assembling it again as there was not much in way of support for the screen. What I found inside was quite simple. The whole thing is SMD and there are three boards with flat ribbon connectors between each. The problem was a booger type splatter of solder shorting three pins on the FM module. It was pretty easy to scrape it off with a dental pick. It was obviously "wrong" and not supposed to be there. I was surprized just how crappy the solder job was - there are micro globs and little balls everywhere. I wanted to clean it in some Meths with a toothbrush but I was not sure what that would do to the LCD screen so I just blew it out with a can of compressed air. So all good for now. They have a ways to go before they give the Japanese and Koreans any frights with quality control!
