That's a delamination issue. I'm surprised you were able to resolve it..

I'll attribute that to its long life so far.

I've been seeing a rash of two year old Samsungs coming in with the edge lit LED strips absolutely trashed. So bad that they are shorting through the barrier and making contact with the aluminum substrate and therefore grounding out.

The problem with the edge lit versions is that they damage the diffusion barrier behind the screen where it comes into close proximity with the LEDs.

Turning down the back lights is crucial if you want more than two years out of any TV.

In the case of CCFLs like yours, turning the backlights down would extend the life of them but even run full out, they are good for 30K hours minimum, and I've seen several at 60K hours still running fine.
