My Treo 650 cellular phone cannot turn on.

Same thing happened to me about a month and a half ago. I own a 680. I had to open the unit to try to dry where water leaked in. A cellphone technician advised me to try a vaccum cleaner to **** the water. But I didnt do it. I used paper towels. Next get a Ziploc bag and fill it with about 1/3 cup of rice. Leave it sealed for a week. Rice absorbs any remaining humidity inside the cell. Then, try to assemble it partially to test it. If nothing happens leave it another week. I used a hair dryer, at some point to make sure it was dry, but dont overdo it cause extreme heat can damage components. Be careful at opening, I disconnected the LCD data ribbon and its been difficult to stick it back together. Now today, finally I was able to turn it on and everything works fine with the exception of the LCD light. I can see whats on the screen but I need an external light source, maybe replacing the LCD screen will fix it. Good luck with the repair.
