I'm a TV tech. The whine is likely the power supply. It may also have to do with the backlights, but again, causing the power supply to whine. To be honest, it may go on like it is and never be an issue. It may increase in time it whines, and eventually whine all the time. It may also be the beginning of the end. I'd continue using it until such time that it poops out, gets too irritating, or you desire a replacement anyway. A Guy
