Screen blinks when blocked - 3G Sony Ericsson Xperia mini pro SK17a - Android 2.3

[#1]

I have the following sony cell phone:

3G Sony Ericsson Xperia mini pro SK17a - Android 2.3

what happens here, is when my screen is blocked, it does not keep all black, it keeps bliking, and with that, my battery goes away very quickly.

Does any body have a problem like this??

Thanks in advance.

there might be an app acting up like a taskiller, battery defender, anti virus, etc.
