    A few days ago I bought and installed the Insignia 40" N10 TV. There were no problems, and the TV is working fine with an over-the-air antenna, and a basic DVD player. A small but nice feature is that the speaker loudness can be changed when the mute is on. Previous TV un-muted when volume was changed. The N10 is a basic TV - not smart, not capable of playing movies from a memory stick - it can display static JPG files. I did buy the additional basic 5-year warranty.
