Samsung has agreed to repair many common problems out of warranty, DLP light tunnels, white specks from failing dlp chips, with enough complaining they've repaired DMD board failures, etc. Sony has done similar with the optical block problems. And I'm sure others have as well.
Why start some "fan boy" comments when none are necessary. We are discussing a problem and trying to help OP.
Samsung's Executive Customer Service (ECR) is where to take a problem you know from research is common. They are the ones who may help. The front line Customer Service exists to get rid of you or refer you to service you pay for.
None of the manufacturers are perfect, some are responsive with a little pressure, some will never do anything. Samsung is among the ones who will do reasonable things if you call ECR. Just a fact, not an endorsement or fan club member.
