W800i White Screen of Death

[MariosX]

My phone got the white screen of death for the 3rd time yet again...
I would like to know if it is possible to repair it by myself
Is there any guide that helps fixing this problem?

I have tried the following:
Cleaned the connections
Removed SIM Card and Memory Stick to see if there was a problem with them ( I removed them for 2 whole days)

Please I do not want to give it again to Sony Care because I will lose my contacts list and pay them yet again..

Please help me...
Thanks in advance

PS.) I would greatly aprreciate it if someone directs to me to a guide for fixing W800

Try to delete files from phone memory. Keep as much phone memory as possible. transfer all the games to mem card via "more" option
