I recently bought a refurbished Samsung Blu-Ray. But yesterday, two of my Star Wars disks wouldn’t play. The screen got that telltale tiling (those pretty purple squares).

Then I ran the cleaner. No change. Then I called Samsung. By then, the Star Wars discs were working again. Huh?

Samsung checked on my firmware. It was already up to date. And since the “trouble went away,” we ended the call.

Today the Star Wars discs wouldn’t work again, so I ran the cleaner again. No joy.

Then I tried something that shouldn’t work. I unplugged and plugged back in the Blu-Ray player.

It worked.
