Sony tv goes off when teletext selected?

Question

This is a Sony KV24WX1U (BE3D chassis?) tv, which goes off and displays two flashs of the red standby led, when the teletext button on the remote is pressed. For a split second the screen shows text but it looks dropped with a black band across the top. Also, I see the tv goes off the same way when the format button is pressed. Please, to suggest what area of the circuit to check as I am not familiar with this up to date stuff. I have access to the be3d chassis diagram. Thanks to you.

Thanks for the advice.  I will try one of those one for all thingies,although I kind of think it being the remote is a bit remote (punintended!). I'm always ready to be amazed.Thanks,David

May be multiple things happening including the set thinking there is a problem since all of a sudden the black screen (Cut off) occurs with limited video information (Box and limited Text). Nuisance protective shutdown, etc. Have you checked out SONY's web site if there are any service bulletins for this particular chassis?? Could be coincidence but worth checking out, esp if the symptom occurs always when you are attempting use of these features.
