Our Westinghouse flat screen t.v. has been playing DVDs (from a regular DVD player) for over a year now. It is not hooked up to cable (only plays DVDs for the kids). All of a sudden it's displaying a yellow triangle on the screen with an exclamation point that says PSCAN and the DVD movie is split in half.
