Hi:
I have a Panasonic CT-27D10B 27" tv that exhibits the following:

1) set is operating normally, then, instantaneously it shuts off (as if
someone used the on/off switch to turn it off). It will come back on
anywhere from 10 seconds to maybe 5 mins. Sometimes it will display the
setup screen, sometimes not.

Any ideas what may be causing this?

Thanks
John
