Hi,

I recently purchased a 32" "no-name" (Insignia) LCD flat panel TV for the
bedroom.

I am quite satisfied with it except for one major problem. Every once in a
while (say, once every other day) the TV will spontaneously switch to black
and white. If I change channels the color comes back and all is well again.

The TV is less than a month old and under warranty. I will have to return
it, but I am curious what may be causing this problem. Your answer will help
me decide if I should exchange it for another of the same make and model, or
pay considerably more for a better brand. Thanks!
