Clean Samsung Rugby II after water damage?
I fell into fresh lake water with my Samsung Rugby II SGH-A847 in my pocket. I imediately took out the battery and dried it off with a towel and set it in a hot truck to dry more. Samsung says this model is water resistant to 1 meter immersion. After several days drying it turned on displays the normal screen, but displays "searching" for the 3G network contimously. If you try and make a call it displays "emergency calls only". I took it to my dealer and he checked it with another SIM and said it is not the SIM.
Should I take it apart and spray it off with isopropyl alcohol to clean it. One circuit (short between two surface mount chip contacts?) seems to be shorted and causing it to not function. efertthing else seems to work.
Thanks much if anyone has any ideas.
P.S. Where do I get a manual for dissassembly directions?
