Rodger, I definitely would start off with [guide|5825|this guide]It is for a 3G but essentially the same procedure. I habitually '''change the battery''' on a liquid immersion. You'll be surprised to find out how many errors a water damaged battery can give you ;-) After that, reevaluate, clean again and see what you get. The order I'd proceed is Clean>new battery>LCD>logic board. ifixit does not sell iPhone Logic boards, so you would have to do some internet scouring to find something close to your location as well as financial situation. You could contact places [http://www.missionrepair.com/iPhone_4_Repair_and_Diagnosis_s/429.htm|like this.] Apparently they do offer board level repair. Hope this helps, good luck.
