    Same problem k850i, keypad light goes on, phone vibrates once and nothing else. phone customer support and they told me straight away to take it to service centre. sounds like they have had this problem a lot.

I think the wires that go to the screen are broken. they tend to do that on slider phones and flip phones.

Sony ericsson k850i screen is black whyl the keypad lights.. i tried to update it but nothing happens.. help me.. pls..=(

If this was happening and the update was possible (and successful) I'd try opening the phone up and make sure that the screen connector is properly connected, especially if the phone has been dropped or has taken any type of physical shock.

Otherwise, this could possibly be a water damage related issue.
