    Okay first off I dropped my Droid 2 in the toilet and quickly pulled it out and took out the battery. I've had it in rice for around 40 hours so I plugged it in. It charges, vibrates, receives calls, texts, has sound so I know it's on. When I touch the buttons and the screen it vibrates as if I'm unlocking it. I just can't see the screen, it's black with nothing like it's off. Has anyone has this happen? Maybe a cable is loose or needs to dry longer?? At worst I'm willing to buy a replacement LCD and put it in but if I were to replace it and then have a bunch of other phone problems with the phone that would suck. So if any one has any suggestions that would be great. Thanks.

    I'm assuming you don't have insurance. You could replace the screen and hope thats the problem. I have repaired many phones and water damage is the hardest thing to work with. The water could have done damage to the board or it could just have damaged the screen. If it were me I would replace the screen and hope for the best. Just be sure to only get the LCD and not the digitizer as that doesn't seem to be your issue, unless you can get both cheap.

    Is it the backlight or is it the digitizer? Replacement digitizers are available but aren't cheap. Neither is getting them replaced.

    Sounds like your phone is screwed.

    Is the digitizer the thing that recognizes touch? Cause it recognizes touch so I'm thinking backlight because the bottom home button and search button and all of those don't light up.

    That's a whole other kettle of fish. If the backlight is all that's out, however, if you shine a light on the screen you'll see more than just flat black, however.

    I don't believe its the digitizer. That is just the top layer that senses touch. The lcd is what has the actual display and backlight. If your board is corroded at the lcd contacts then a new one may not help. I would take it apart if you can and look the board over for corrosion. Im not sure what lights up the buttons though.

    I am probably going to order a new LCD screen. I can see the screen a little bit and read some words under light I was actually able to read the time on the phone. What should I look for on the board to see if it's corroded??? Thanks

    I was able to see that I received an email as well so the internet seems to work.

    Also is it possible that the flex cable is just broken???

    I would doubt the flex cable but anything is possible. Look for any discoloration or white marks on he board. Especially the lcd contacts. You may be able to clean them with isopropal alcohol but it doesn't always help. I would definitely look at the board before ordering a new lcd. There are probably youtube videos that can help with the dissasembly.

    Before I unsubscribe because I'm totally useless at this point, might I assume the water damage stickers were tripped? :)
