Default Looks like dead pixel - Samsung DLP

Have a Samsung HLS4676SX/XAA that all of a sudden has a bright white dot about 1/8" diameter near the right side.
Looks just like a dead lcd pixel.
TV is ~ 2-3 years old and has been excellent up to this point.

Thoughts?
I've never replaced the bulb yet.
Any correlation to the bulb? Dust on the mirror? Damage to the mirror?

Not the bulb, sounds like a stuck or damaged mirror. Might be costly to repair.

What you are experiencing is getting to be a common problem with the 46" Sammys. It's the dmd board going out. More squares will continue appearing till the whole screen looks like it's snowing. There is a huge thread elsewhere where a group of people have repaired it themselves and supply all the directions. If you fix it yourself it's not very expensive. So if you are good with computer repairs, post back and I can email you the link.

Or go to google and put in: "samsung dmd board repair", and it's the first link.

Glad you knew exactly what it was, thanks...

Having three Sammys I've kind of made them a study so I can keep them as long as possible.

Good to see you back.

Is this the link your referencing?
http://www./avs-vb/showthread.php?t=1107926

Does not sound too terribly difficult.
Do you have additional info / links to share?
Where can I find the service manual for the HLS4676S? Did a google search and did not find much.

I moved the entertainment center with the TV on and the HDMI input unplugged; just after is when this spot appeared.
Can't help but think I may have sped up the problem.
So far only the one spot.

You can't post links to other forums here...they will never work.

Did not know that; explains why the page would not come up....
I assume I can PM you.
Will you PM any links / info you have on this repair.

Still just the one dot.
At first it was the worst thing I could have seen; after seeing pics of other sets with all spot covering the full screens mine does seem SO bad. Still plan on fixing.
I believe I have the extended warranty from Best Buy but not sure where the recpt is and need to contact BB to pull the records.

For sure it does sound like the dmd board its composed of a tiny miscrospic mirrors about 2 million of the m that create the image it must me that some pixels are in the off position ,you will need to replace the dmd board,they sell the whole thing light engine but I suggest just to get the dmd by itself.

Default Spots gone - fixed under x-warrant

I'm glad I purchased the extended warranty on this purchase; Geek Squad guy came this morning and replaced the entire light including a new bulb.

I had just under 7000 hrs on the original bulb and we can see a bit of an improvement in the brightness.
Of course we no longer have our own private planetarium

So glad to hear you got it repaired without any extra cost...
