hi ken,
it says toshiba on it.. model # says k29cr55. i believe it's really a nanao.
i can hear ticking sounds when i listen from the back of the monitor. these ticking sounds correspond to the horizontal flickering white lines that appear every couple seconds. it goes tick-tick-tong. sometimes there will also be a high pitched whine sound too. other than those horizontal white line flickers, the picture is perfect.
thanks.
kenzo
