I still think it's dust. you said it got worse after the DMD repair. Well they open everything up for that and dust gets on it. That's what happened to mine and then he took it apart and cleaned it and it was gone.

I got a three month warranty from the company that installed it. If you got one call them back...

It's been over a year, so if there was a warranty it's expired now. My point is that the pattern was there and focused on one spot about 6" x 6" before the repair. I can see where dust would cause the light to diffuse, thus spreading the pattern out randomly, but it doesn't explain what the pattern is and how it got there to begin with.

Hello All,

Just a quick note. I recently began to receive the dreaded white dots and have at least 50 now. I just called 1-800-Samsung, explained the situation, and without any fuss was told they would replace the DMD chip one time free of charge. I am now waiting for the service department's call to schedule the repair.

I'll keep you posted.

FYI... I have the HLT5676SX/XAA model.
post #1894 of 1965
Wow that is is pretty good service.
post #1895 of 1965
That's exactly what they did when I emailed about my HLT5676SX/XAA.

Its been four years and this TV is running ok, but considering I never used it as an everyday TV it should be ok. This is the 5076s by the way.

Recently moved and when I turned on my set at the new place, the screen was all messed up. The volume bar and anything in that area was below the screen. When in 4:3 mode the sides converged horribly to the top center. There was also about a half inch black line running horizontally across the top where there was no picture.

Luckily I had one week left on my 4 year BB warranty and the guy came the day before it expired!

He really knew his stuff too. He took about a half hour and said the mirror was knocked out of alignment. When he left the TV was looking great and hopefully it stays like that, knock on wood!

If anyone has any questions just ask. Just thought Id share a bit since DLPs are pretty much dead are they not?
post #1897 of 1965
What did he adjust?
post #1898 of 1965
All he wrote on the slip was "align mirrors."

This is a thread with pictures of EXACTLY what my TV was looking like:


http://www.avsforum.com/avs-vb/showthread.php?t=1182259


He told me it was the mirror(s) at the top of the set. He took all the screws off the back, messed with it for awhile, and then he got it centered almost perfectly.

He told me he was happy it went so fast as he said he's spent hours trying to get the mirrors perfectly aligned.

He said to be real careful about not pushing in the top of the TV, but I never did so I am thinking something during my move must have jarred it loose.

Anyways I went from thinking my TV was junk to having what seems like a whole new TV again. Its got a total of 782 hours on it since it was bought brand new in April of 2008 for $900.

I see there is firmware available for it but I think I will just keep it as is as long as its running ok.

If you have any questions Ill be more than happy to ask.

Thats what they did to my tv also, then when I moved it changed again, the guy moved the screws in the back around and got it perfect.

Is this a fairly easy process?

I may need to do this in the future if I move again lol!

Thanks for your help.
post #1901 of 1965
He made it look easy I watched him he loosened the screws a little and moved them around intill it was perfect.

Is there any way you could have instructions for me in case I need to do it?

I was in front of the TV and didnt see what he was doing since space behind the TV was kind of crowded.

Now I wish I watched more closely...

It's easy to adjust the mirror, (this adjustment only affects the bottom of the picture). Loosen the four phillips screws along the top rear of the set, then turn the slotted posts next to the screws a small amount to raise or lower the bottom edges of the picture. Finally, tighten the four screws. You will need a grid pattern such as the program guide on the screen to do this.

He adjusted something else. I know what screws you are talking about and those didnt do the trick. Those screws just barely moved the picture and my picture was inches below the screen.

Those screws moved my picture a lot, He used the grid pattern in the sevice menu.

Well, now I have some white & dark spots. I'll call Samsung & hope for the best. Maybe they will offer the one time chip replacement as they have others.

Called the Samsung 1-800 number & to my surprise; they'll do the one time replacement of the DMD chip. I say surprise because I expected to be passed on a few times before getting someone to agree to do it free. In fact they offered without me asking. Weird! Samsung has come a long ways since all the bow issues when we 1st got the set. Back then they didn't want to admit they screwed up. Anyway, should get a call later today or tomorrow.
post #1908 of 1965
I should of updated this sooner but didn't. Anyways, the tech returned last week & installed the new DMD chip. It took about an hour. He cleaned the dust off everything (outside), adjusted & buttoned everything back up. Overall very pleased. There was no charge. Good deal Samsung! More business coming your way in the future.

Hi all,

A major video game release is coming in four days and I would like to attach my Alienware laptop to my home theater and play it. However, in the past when I plug it into my amp and run it to my tv the picture is somewhat off center and the contrast and brightness are way off. My other tv has a computer mode that seems to work okay for issues like that but does anyone have any suggestions for setting up a computer (HDMI) on the hlt-6176s easily? I was hoping not to have to mess with the default picture settings if I could avoid it... Thanks!

I too had the white dot issues (and a black blob from the screen detaching I think) and Samsung replaced both for free about a year ago. Otherwise, I still love how this TV does movies!

Can anyone recommend a source for projector lamps that are genuine oem that they have actually purchased from without issue. Seems to be a lot of "internet wonders" selling these parts with prices all over the map???
Samsung HLT5676.

Thanks,

They sent an exact replacement housing & all.
post #1913 of 1965
ShopJimmy has them for much cheaper, and they're generally considered a reputable source: http://www.shopjimmy.com/catalogsearch/result/?q=BP96-01795A

Great prices but are the OEM as gmanhdtv asked? I paid more for mine but got a new housing. Everything was exact. Replacing bulb only looks simple enough & would save more but I didn't shop bulb only.

Went with an ebay seller on bare lamp only, oem by Philips. Had excellent feedback and $79 shipped. Will update everyone when it comes in. Bare lamp is easy to do as I did this on my RS1 as well as my current projector Infocus SP8602. Housing's are plastic and silly to waste.
post #1916 of 1965
Ok. I have been searching for weeks Know to find out the settings in the service menu. I see other people posting about all the others but have not found one about the model I have. I just wish someone would post the settings for me. My Tv looks bad and i want to keep it but. I am trying to fix it. Can someone please start with the DDP 3021 and go all the way through into the other service menu so that i can compare mine to. I would really appreciate it. I have the HLT**76sx

Bulb arrived in 3 business days from Illinois to Florida. Genuine Philips lamp. Set looks brand new.

Purchase details: Bought set off Craigs list for $100 last Monday, called Samsung as I already own a Samsung 50" dlp in family room, Samsung Blu ray player, and computer monitor. Explained that the tv had the "white and black spot issue" she looked up my account and saw I was a regular Samsung customer. She came back online and stated that they would fix for free, repair was made last Friday.

HLT5676sx for $179 out of pocket with no cosmetic damage!!

Craigs list is full of people unloading defective dlp sets as "thin is in" shop wisely and you can score an excellent deal on a used set!wink.gif

I have recently inherited my parents samsung dlp TV.

The bulb burned out (this happens every 2-3 months) so they got fed up and bought a new sharp LED tv. My parents were also very fed up with the white spot issue that keeps getting worse with the TV.

I called samsung and they are coming out Monday to replace the dmd chip (what exactly is this?). Hopefully this fixes the white spot issue!

My questions are this:

Is it easy to adjust the mirrors on this set? The picture seems to be skewed (maybe a couple of degrees). It isn't a huge deal, but it really bothers me.

Why might the bulbs be burning out every 2-3 months? Is this related to the DMD chip?


Thanks for reading guys,

- Matthew

DMD - Digital Micromirror Device. My understanding (anyone; please feel free to correct me smile.gif) is light from your projector lamp illuminates the DMD, which is projected to a mirror, then reflected to your screen. Most lamps are good for 2000 hours so 2-3 months isn't normal unless, perhaps, low cost replacements are used. Replacing the DMD will require a mirror adjustment & should be included in the DMD service. Many of us have had the DMD replaced. My understanding is some of the micromirrors fall off or stop moving causing the white spots. HTH
post #1920 of 1965
DMD chip is certainly the cause for the white spot issue. Not sure why bulbs would go so quickly unless they are cheapies. Go with a good philips bulb and it will probably do much better.
