Nokia 3588i Keys 2,5,8,0 not working?

Nokia techs. said that the reason keys were bad was because of corrosion damage thru POE charging jack?
Any possible fix?
Thanks

Hi , as you see , you have problems with a complete column in the key board , perhaps you have a track damaged in the board , try to find it , and fixed it ( you may need a microscope for this job).

Corrosion may cause tracks to damage.

Also the problem could be the antiestatic fuse ( a little BGA plated chip ) , its placed electrically between the keyboard and cpu , and prevents cpu to be damaged with static ,this bga chip may be changed .
