Hey there, I've got a really bad problem. I accidentally knelt on my kindle paperwhite... Heard a crunching sound, now the screen is frozen though there's no external damage, I know this is pretty hopeless but is there /anything/ I can do ?
sound like you damage the device. only way to know is replacing the screen but before you need to see what else got damage. most cases get a replacement or buy a new one.
If you're thinking of having it repaired instead of buying a new one, check out the prices from independent cell phone stores, not just normal PC or electronics repair centers. The prices vary widely.
