My blackberry curve screen keeps turning white

Have you tried different chargers?
It's either the voltage regulator in your curve or a very weak almost dead battery.
You can test the batt if you have a friend with a curve, swap batteries in your phones and if yours works again and his does what yours did, get a new battery and all is well. If yours keeps acting up with the swapped battery, it may be time to get a new phone.

Wipe it to start over. Sometimes when you change or add something like a THEME or a download it HOSES the BB completely. So delete what was on there and don't download a theme or any other wacky add-on.

Sounds like your screen is physically broken. If your Somebody needs to open your Blackberry and replace it. If you want somebody else to do it for you go to Blackberry Repair. If you want to do it yourself, here is an Blackberry 8520 Repair Guide that shows how to repair a Blackberry.

No. There are some sellers on ebay which sell you a kit to clean up water damage on your cell or BB, but it's super hard to do without breaking the device. Even with instructions, it requires you take everything apart etc.. And its like $40-50 for the kit.

Sometimes you get lucky and up to 3 weeks later the device will dry out and work, and I've had some work the next day.. but only about 33% of the time do they come back at all...
