My sony erricson k850i started giving problems a while back. during use the screen would go black but it didnt stop the general use of the phone, I could still sms or phone a number even though I couldnt see anything on the screen. Then my phone went of and never came back on again. I tried software upgrade, I did the whole remove battery and mem card thing I charged it over night etc, there is no responce from the phone at all exept for a red light that comes on deep inside the phone when charger is connected, only visible in the dark pls help
You need to restore the phone to the factory defaults. If this doesn't work, you'd have to bring your phone to someone that can update the phone's firmware.
hi... ur mobile phone has lost its display.. due to display problem the screen appears black for u... thats the problem.. u are in warranty period right now.. so u can contact sony service centre and they will replace u with new display for ur mobile...
If you have a blank screen but the blue lighted ring is on. Remove the back, the battery, remove the 4 tiny screws. pop the front plate off. Carefully remove the circuit board from the case starting from the bottom. On the back of the circuit board you will find a smaller circuit board that is plugged in. This board sometime becomes partially unplugged do to rough handling. Press this board back into its socket carefully. Reassemble the unit and everything should be fine.I repaired 2 Sansa E280 unit from Woot grab bags with this method.
