It sounds like a bad LCD panel but you would have to post a picture of the problem for me to be sure

SOURCE: Sony BRAVIA KDL-40W4000

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

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

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

How to change from ntsc to pal on bravia kdl-40s3000 40 "


Changing this requires a change of the tuner. There is nothing inside the set that can make this change. There are external systems that can do this, but they are expensive (multiple $100s).

Bottom line is that this would require a change in the internals of the set.
Hope this helps.

Try different cable, if you still get the problem after replacing cables, then you have a defective sygnal board (input board).

You should have a 1 year warranty from Sony. Call them before it expires. This is probably a LCD panel issue.
