I have an KDL 40XBR4, 9 mos old. It has started intermittently displaying duplicate pictures like a very bad ghost image; this sometimes goes away when we turn the tv off and back on, and sometimes not... I am connected to cable and it makes no difference whether the box is on or not ; it also does the same when running a dvd player. The tv is connected thru a panamax power manager and I have disconnected it and tried connecting it to the wall plug directly as suggested by Sony, however no change. All connections are tight and cables new.
Sometimes while watching the tv, it will suddenly go black with a slight purple horizontal lines on the left side. Of course if I call a repairman, it won't do it when he's here.... Any suggestions?

Re: Sony Bravia- ghost images and more
Since this set is still under warranty, DO NOT open it up at all. That will void the warranty. Your best bet is to report the problem and request service. Request that this service be scheduled for a few weeks out and try to see if there is a pattern to when it occurs. For example, does the problem seem to occur most often after the set is on for a while? Any information that you can provide to narrow down the conditions when the problem occurs will be helpful. Please report this as an intermittant problem. Even if nothing is intially found, if the problem becomes more regulatr after the warranty period has expired, it should still be covered.

this is due to a defect in the lcd panel where the ribbon connectors that connect the panel glass to driver boards have come unbonded. you can flex the panel and makesymptom come and go. panel replacement is the only lasting fix. have a nice dday and thank you for using FiXyA. Regards, meder's tv service
First,If there are double images or "ghost" images on the TV's picture, check the cable connections and make sure they are secure.Because the loose cable connection would be a chance for the ghost picture
But if the cable is perfect and if you still get ghost picture then here is the solution:
The LCD Panel is defective. The problem is the T-con board that is used to decode the signal from the main board to the LCD Panel. The only way to fix it is to replace the whole LCD Panel or T-con board if possible. The T-con will cost about 1/10 of the price as the LCD panel but except for a few new models, the T-con is not available. The LCD Panel is very expensive (usually from $600-700 for a 32" Sony).
The reason is that Sony makes the T-cons for each individual TV with different specs to match that of the LCD panel because of the low threshold for error between the LCD Panel and the T-con.
Its best to avil warranty and change the panel...

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.
colour temp: Warm 2 (although Warm 1 is less yellow and still fine)
noise reduction: off
mpeg nr: off
contrast enhancer: off
colour space: standard
