There are things you can try. Some of it im sure is like old wifes tales and just get spread around forums. For what its worth.
Things i have seen posted.
Gently masage the area with a clean Q Tip. the treort here is that its stuck and needs a prod to get it moving again.
Gently tap the screen with your finger, same reason.
On a more realistic note i have hundreds of CD's here with calibration/Check/Dead pixel checker/Fixer etc. So it would stand to reason that if they come on a free disc then you can Google them as well.
What you really need is someone who has been there and fixed it.
Hope you get it to work properly. Chances are it wont though im afraid.
