Make sure the fan, heatsink, vents are clean. Replace Thermal Paste if needed. Try a restore to a date before this issue. Have you done ANY updates? Any damage? Try rolling back the Graphics Driver. Is it a Nvidia Graphic Adapter?

Hi visit mobileunlocksolutions.com to unlock your Sony Ericsson k200i mobile from orange network .here they ask you the imei number of your mobile .finally they send you code to unlock your mobile.

If you meant blocked SIM , this is done by your serrvice provider is the necessary document are not submitted. So please contact your service provider - call on their toll free service centre.
If your phone is blocked then it the unlocking code must be received also from the dealer or service provider who sold this phone. If this SIM locked , the the service provider will unlock only after the said period of one year normally. This is because the phone was subsidised to you.

Most likely it's graphic card problem, but also may be monitor itself. First, check the signal by connecting to TV (if yours has a PC input), then replace card if that shows the same.

Most likely an electronic item could have broken in the circuit board, a resistor, transistor, capacitor, etc. Take it to a technician at a repair shop. Have them take a look at it, usually estimates are free.

ur knock sensor is located behind ur engine and it is attached to ur engines short block.

PICK HIGHER RESOLUTION ON SETTING,

Hi,

I am sorry but there is no such function on this phone. However, there is a white list option. You can accept calls only from numbers on this white list (and everything else will be blocked)..

CCD sensor block needs replacing. Sony should do this free of charge. IF you have to pay for the repair it is not too expensive because this particular job requires only +- 1 hour labour and the CCD component is not that expensive.
