I am still in resurrection mode trying to get a 2007 MB 2.2Ghz to replace a 2006 Mini so I can go to Lion. Got 4GB and a new battery earlier in the week and now I have some screen flicker. All posts and internet threads reference an inverter but moving the screen changes the flicker and in some cases stops it (only temporarily though) which seems to infer a loose connection more than a bad inverter. Anyone had a similar issue? I need to upgrade the HDD in this thing but before I pour more $$ in it I want to get the flicker issue resolved.
