Sanyo DS31520- high pitched whine, picture is fine 32" tv, about 4 years old. Picture is great, but there is an annoying high pitched whine, that seems to be involving the area where the video imputs ect go. If you move them around or bang the TV, it sometimes stops for a while. Any suggestions as to what is causing it, and could it be repaired by a handy person? Thanks!
