TV & Home Theater

[gjrxg1]

I have noticed twice now that when my Insignia LCD TV is turned off it has done a sudden "flash" as if the monitor is going to go on.  This happens on its own.   I recently had Direct TV set-up and did not know if this is related to the situation.

What is causing this "flash".  This is not normal as I have an 32" LCD with Direct TV as well and it has not happend.

Thank you.
