Sudden picture problems - color distortion and "negative" picture appearance
I've owned my Sony KF-42WE610 for about 3 years now and all of a sudden when I came home and turned on the TV something was wrong with the picture.
Certain colors do not appear to be showing up and the picture generally has a pink tone to it. Overall the picture is very snowy and the best way I can descibe the picture is that it has some sort of a "negative" effect.
I'm wondering if this is a bulb problem given that I've had the TV for 3 years now, but I want to be sure before going out and buying a new bulb.

symptoms of a defective CCD
include distorted images or abnormal colors, scratchy purple lines,
blank or black pictures, and/or black videos with good sound being
recorded on the camera's flash card. A
problem has been discovered in some of the CCDs used in Panasonic, Fuji, Sony and Canon digital
camera and digital video camera products that causes images to appear
distorted or not to appear at all. And the says apologize for the considerable
inconvenience this represents for your customers. Along with our
respectful apology, we would like to advise our customers of the details
of this issue and our policy for handling it, which are as follows.
The Malfunction: Among
the CCDs used in the affected products listed above, it has been
confirmed that, especially under high-temperature/high-humidity
environments, the internal wiring may come undone in some places.
this defect occurs, the signal is not output from the CCD correctly
when in shooting mode, which results in symptoms like the following in
captured images. These symptoms can be confirmed on the LCD monitor. The
same symptoms may also occur in recorded images: * images do not appear * images appear distorted
In order to correct this issue, the repair facility needs to replace the CCD. This is not something you may do on your own; this, isn't a good new, but hope helps to solve it.

Depending on when you bought this TV, this could be the lamp. Does the red light below the green light come on? (That's the lamp light). This light typically comes on around the 3rd year of use for an average individual. I've recently enountered the same problem and will try to replace the lamp myself. Apparently its very simple.
