Also I have a Sony Bravia and it clicks while it is on as well. I read that forum and some people said to disconnect the cable box for 10 sec. and then some said it was the heat from the summer.. i don't know.. I just turned my tv off and then back on and it stoped. I read this is happening with all kinds of TVs....

Unfortunately, this is a failure of the balancer board for the backlight. The unfortunate part is that the balancer is not available by itself anymore, and the whole panel must be replaced, as Sony only has the balancers attached to new panels. You can contact Sony directly to ask for assistance, and it usually helps.
Hope this helps you...

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.
