Given the many TV models, it's possible that accessing control of this feature in the Program Guide menu may differ on your TV. For specific instructions for your model, see your owner's manual.

you are that clear

but if you are talking about flashes on the t.v then it is due to sparking is taking place in your plug & socket.

if it is ok then there is a sparking in high voltage section in tv which is called fly back section.

good luck.
