I tried to take this phone apart once before to try to dry it out after my two year old daughter put it in the toilet but was unable to separate the two halves of the phone. Fortunately after a couple days of sitting with no battery, and some time spent in the oven and under a hair dryer my phone made a full recovery from that incident.
This time I tried some percussive maintenance but was unable to restore the screen. Time to dive in, and this time figure out how to get the thing apart far enough to extract the LCD. If your Samsung slider also needs an LCD replacement then follow along.
