someone told me it might me my inverter. how do i confirm it is my inverter and now the LCD itself? and how do i replace/fix the inverter. thanks.

The only way to confirm it is the inverter is to replace it. Refer to the T61 Maintenance manual for the procedure.

before i go ahead and order, is there a diff between foxconn and sumida i should know about?

I have no idea, but normally if two manufacturers are listed for the same part they are both compatible.
