My Samsung 67" has white

sound like you have samsungs dlp white spots plague, which just gets worst. samsung are aware of the problem, so you need to get in touch under the warranty.

The model number almost certainly is a wd one.

Set is a DLP set with a lamp and 98% chance the optical light engine is the cause. Some of these start with one or two out and gradually it can get worse with more and more appearing over time.

It is about the most expensive part in the set.

Sorry, but I have seen them since the first DLP sets came out.

Replace the optical engine. See my tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine for help with getting a new one and installation.

Thanks for using FixYa and for the great rating.
