On my HL-S5686W, the chip is a PGA type (similar to the CPU chip on a PC if you have ever replaced one of those) so it is pressed into place. I have never seen anyone else on this thread mention having to solder, so I presume it's the same across their DLP line.

If you have one of these models, you will need to check the version listed on the right side of the TV:
HLS**86WX/XAA
HLS**65WX/XAA
HLS**66WX/XAA <---- (This would be you. )

If you have a Version PB02 the DLP part # should be 4719-001981.
If you have a Version PB01 the DLP part # should be 4719-001968.

Checking the version is the only way I know that doesn't involve taking the whole thing apart.

I also have the HL-S4676. The chip pops in -- just align it properly and apply pressure. I was surprised by how relatively easy this step was, and took the chip out and repeated the step just to double-check my work. No other fastening application is needed.

I have a Samsung DLP TV, model HLT6189S and today we noticed our first white pixel appear.

Now after reading through this thread, I'm hopeful I can get some advice from the experienced people here.

We just passed the two year point of ownership.

1. Is this issue fixable in my model range as I've read some have had success in the HLS model range?

2. Is there any information I can get on specifics concerning my model and the pixel problem?

3. Are there any part's and part numbers that I can replace for my model?

4. Any other steps to take in this troubleshooting headache of a defective part that clearly belongs with the manufacturer and not the consumer?

5. Any advice or guidance concerning this?

Thanks,
Brad

I have been looking for the solution to a few problems that I am having with my 3 or 4 year old Samsung DLP HLS5687WX/XAA. The problem is that the image now has a strobe effect and the tv used to shut off the image while the sound continued. I have replaced the bulb as well as the color wheel. The new color wheel has been in for three days and the first day it was in it continued to shut off and play sound but the last two days it hasn't so I'm not sure that that problem is fixed. The picture is still fluttering/strobing. I was told by a local tv repair person that if the color wheel didn't fix it then it was the DMD module; is this true and if so what is the part number?

OK I have the White spots too, after reading numerous pages I have figured out I need this chip, I have the part number and everything.. My problem now is there is so much information on here i cannot find the step by step instruction on how to change it or where it is even located at on the television, If someone could please point me in the right direction to find these step by step instructions I would be very happy, thanks for all the help..

Looks like the DLP chip that samsungparts.com lists for your set is part number 4719-001997.

HLT models are a little different, but apparently still doable. See MattZTexasU's web page that just linked above... he did his repair on an HTL5675S.

Sent you a PM for some info about Consrmer Protection.My 5688 goes from a good picture to about 200 scattered white pixels and my warranty just ran out I spent 3500 when they first came out. I had to change the DMD board about 18 months ago.Now I cant find any anywhere.

Well, I guess I have the same problem.

I have HLS4266wx/xaa PBO2

White dots all over, guess I need the dmd board.

Anyone know where to get it and then step by step directions on how to put it in?

thanks

If you have one of these models, you will need to check the version listed on the right side of the TV:
HLS**86WX/XAA
HLS**65WX/XAA
HLS**66WX/XAA

If you have a Version PB02 the part # you need is 4719-001981.
If you have a Version PB01 the part # you need is 4719-001968.

Places to buy parts online:
http://www.samsungparts.com/
http://www.partstore.com/
http://www.encompassparts.com/

Manuals and documentation are here:
http://www.drop.io/HLS5086W
You will mainly need "disassembly reassembly.pdf"

But....some say I need the dmd board, some say I need the dlp chip?

Which is it?

Or, do I just need the part number you told me for the white dot problem?

thanks again!

The part numbers that I gave are for the DLP chip, sometimes also called the DMD panel.

If you have white spots (and most likely a few black spots a maybe even a couple that flicker,) then you need a new DLP.

I only had ONE white spot but it was annoying. Replaced the chip and now its gone.

I do have one other (new?) problem. When the screen is totally dark I can see two circles in the middle of the screen. I didn't notice this before I replaced my bulb and chip. Did I do something wrong? You can only see it on very dark sections when they are in the middle.

Help?

Usually, the "engine" refers to the entire projection unit... including the DLP chip. When was that replaced? Recently, or has it been a while?

So, has anybody got anything out of Samsung yet? I can't believe when there are this many people with the same problem that they won't do anything about it. It would be great if they would at least pay for the replacement part.

I ordered my part they other day from Samsung Parts and it is on back order. Don't worry they will have some in about 4 weeks!!

I've got over 100 white dots now and I go to the bedroom to watch tv on my non-hdtv now.

I called Samsung to complain about my HLS4266WX/XAA which was purchased in December 2006. I have over 100 white dots and told them they should pay because this is obviously a design flaw or bad parts on their part. I referenced this thread and was told if I have a real question other than talking about what I heard on the internet, to call back! They were downright rude. I'm firing off a letter to them now, as if that helps. No more Samsung products for me!

Called 800-SAMSUNG earlier this morning, and I got the same story as most of you no matter how much I argued. Their positon is the set is "out of manufacture warranty period" "there's nothing we're going to do about it". This is ridiculous! I was hoping to go on here and post a update saying all of you are wrong, Samsung is standing behind their product - but THEY ARE NOT!! Our TV was purchased in Dec 2007 for just under $1000 - this is beyond a warranty issue, it is a defective product issue!

There's some great info here about part numbers, and how to replace the DLP thing, but hey.... don't you all agree that this is a SAMSUNG issue to repair - there is clearly a defective component in the television that is causing hundreds of consumers grief. A $1K television should last more than 22 months... period.

OUR PAPERWEIGHT SPECS:
MODEL: HLS4266WX/XAA
SERIAL: B19V3CELA07920K
VERSION: PB02

I joined the facebook group for Samsung owners with the "white dots on screen" problem.

Samsung really needs to step up to the plate here. Issue a recall and offer repairs. There are hundreds of affected consumers out here.

Bought my HLS4266 back in November 2006 and this past May started to get the white spots. I read this thread thoroughly and odered the part and replaced it back to perfection. I originally went to Samsug and got the same frustrating response as everyone else. Then I went the BBB route only to be denied a claim but provided a suggestion to contact the STATE OFFICE OF CONSUMER PROTECTION 124 Halsey Street Newark, NJ 07102. (you can submit an online form). THIS WORKED! Samsung has so many days to make an acceptable offer before the NJ Atty General sends it to arbitration. A very nice lady contacted me from Samsung and immediately made an offer of about the price of the part. I liked that, but I negotiated for a warranty extension. Got that too! My 2006 tv is now warranted through March 31, 2010. Not happy I had to go through this but I do feel a bit better than I did when I saw that first white dot!

PS - Thanks to Pez and all the folks that contributed here!

Good on you roofrack! That is encouraging. Most states have a Consumer Protection office (under a variety of titles). Corporations have a certain distaste for class action suits and will go to considerable lengths to avoid those. Still, it does require legwork and persistence by the consumer.

I'm going to try this through the Michigan Consumer Protection Office. Thanks!

Hello I'm new to Avsforum hopefully someone can help me diagnose the problems I'm having. I have a Samsung HLR6178WX it just shut off, the stand-by/temp light started blinking as I tried to turn it on, I called Samsung they suggested it might be the bulb, or the color wheel, I replaced the bulb, and it would not light.

Any ideas or suggestion would be greatly appreciated.

I got my part in today and installed it. I sat down in front of the tv and turned it on and started praying!! It worked! No more staring at over 100 white dots! I did have one helluva hard time getting that damn clip off though. It probably took me 30 minutes just to figure that out. It just took a lot of elbow grease!

I'd like to thank Joe for starting this thread and Pez for all of his input. There were quite a few people that gave very insightful information. Thanks to everyone. I'll be back in another 2.5 years when this chip goes bad!
