The solution below covers for Samsung Galaxy S I9000 with display problem cause by water or wet damaged.
This may only works if already tried installing or replacing the whole LCD screen module and calibrating the device ROM but nothing happens.

2. Tried replacing or using another LCD screen, but still no luck.
3. Visually check the LCD pin connector then re-solder it.
4. Replace the Display filter ICs. Problem solved.
See pictures below: The pink encircled components are display filters, if damaged will result to LCD screen display problem of Samsung Galaxy S I9000.
