Is there still a back light just no picture. shine a light on screen and look at the picture from the side if you can just see the picture then the inverter is on its way out. if you get a white or gary coulor screen then the screen driver is on its way out.

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....

Hi there,
I've been looking into this myself as I've also recently purchased the KDL-40W4000. I was watching a murky old film and was getting a bit of sludgy ghosting but found that by reducing the contrast to 25, setting the backlight on low, colour on neutral and the brightness about 40-60 (and taking ALL advanced noise functions off), this reduced the ghosting considerably.
BUT, this is quite a cool and dark image. If you watch standard TV and films mainly, a variation of the Cinema setting is probably the best overall setting i.e.
backlight: min
contrast: 79
brightness: 50
colour: 53
colour temp: Warm 2 (although Warm 1 is less yellow and still fine)
sharpness: min
noise reduction: off
mpeg nr: off
contrast enhancer: off
colour space: standard

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...

I have had the same problem with my KDL-40Z4100. After having the power supply, various parts, and eventually the mother board replaced, i was eventually told by Sony that it is the TV Guide updating (it is NOT the cabinet nor anything else cooling off... the most I've had it off for is 4days straight - still clicks ). Sony Rep was very unhelpful (Sean at Customer Information Centre - 1-800-773-9667 ], and told me that even though i 'turned off' the TV Guide update - that it just turns itself right back on ( his words verbatim: "you cannot turn off the TV Guide update" ) -->ergo , clicking will never, ever go away.
This will be the last Sony product I ever purchase. Too bad, as I was previously happy with their products.
Do not waste your time trying to replace mother board / power supply / surge-protector, nor any other parts --> it is not a 'replaceable'-fixable problem ......

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