回答“Why is the LCD screen not working?”Provided it is not that EVF is selected, or lens cover is on, it could be: (1) screen broken (2) screen connector malfunction In the first case it could be caused by a drop or similar. You should see evidences of broken screen on glass. In this case it should be replaced. You should disassemble the LCD. Follow disassembly guide but just step 18, no need to teardown the whole camera. On the second case it could be caused by humidity or water, or even a drop that has moved flex cable from its connector. You should disassemble the LCD and inspect it. Follow disassembly guide but just step 18, no need to teardown the whole camera in the first place. Remove LCD and adhesive tape. Clean every connector and component with isopropyl alcohol and a toothbrush. I managed to revive my LCD that was only showing white light and some stripes. With LCD in place, test voltage on slim power connector/flex cable. On my camera it registers some 15.30V If voltage is ok and LCD is not lighting up (some white light) it should be re...
回答“How do I fix a camera that has been dropped in water?”I bought a Fujifilm X30 with some problems: many buttons not working, powering on but not off, EVF not working correctly,...

As water lets some white calcium and salts residues over metal contacts. Then I cleaned every component and connector with isopropyl alcohol and a toothbrush several times. Even CCD and lens. I'll had to insist hard on connectors, trying to reach every inner pin. If water has entered camera lens, I think would have to replace it. Finally I managed to get everything working! I even disassembled the EVF lenses to clean them (see my EVF lens teardown). Although I could not fully clear humidity traces on lenses, EVF vision was much better.
