SOURCE: clicking noise sony bravia kdl-40v3000

It is most likely the cabinet setteling as it is cooling off. Nothing uncommon with all the plastic that is used in TV's.

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

it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.

The green light merely indicates that power is getting to your TV. The symptoms you describe point to internal power supply failure
