Just took care of my 'dots' on my 5086 with help from this thread...thanks guys. Anybody who has built a computer can do this repair easily...took me about an hour and I had to replace a buzzing color wheel too. So between those two parts and a bulb/housing this thing is costing me about $200/year to operate...and that's with me doing the labor. I must have missed that in the fine print. Last Samsung I'll ever own.

Folks,

This is the part # for a hls5686W light engine. In case anyone is looking for one of these apparently they are on nation-wide backorder (whatever that means).My service company has no idea when they will become available. Some places are listing a 9/10/08 date....

If anyone has more up-to-date info please share.

Thanks!

It looks like the PB02 version of the light engine should be BP96-01633B... You may check and see if that's available (and maybe cheaper?)

First post here. I just started having this problem tonight. So far one white dot in the upper right hand corner.

My Samsung is a HLT4675SX/XAA
PA01

Samsungparts is saying I need the Part Number: 4719-001981

Does that look like the right part?

Great site, Awesome thread

Greg

*EDIT* This set is only two years old. Samsung had to replace the bulb after 2 months it burned out but was great until tonight

PezJunkie,

Having the same problem as everyone. Purchased the chip. Would greatly appreciate you e-mailing me the manual if possible...

breid@paragoncommercial.com

Thank you,

The whole process took about an hour & a half. Nothing too hard, just a lot of little tedious steps. I looked through the alignment procedures, but my set didn't really need anything done to it.

If anybody else is going to attempt this on their own, shoot me a PM and I will share the documentation that I have. (The files are too big to attach to this post.)

Get manuals and documentation here: http://www.drop.io/HLS5086W
You will mainly need "disassembly reassembly.pdf", but the "alignment adjustment.pdf" might also come in handy.

I fixed mine last night but accidently took out the three screws that I was not supposed to touch. I read the directions but when I did it I got too excited. Not too complain but my 46" was a lot different than the instructions and it said not too take out the screws highlighted in red and they were circled in white on my print outs in color . So if you are doing this please read the directions more carefully but it was really simple. So my next ? is that my moving these 3 screws it has screwed up my adjustment and intially left a black line on the side of the tv, I moved it and then it got worst and the 3rd time I moved it and now there is an inch black line where the picture does not show up on the tv. its not bad but when you watch Fox / Weatherchannel with the scroll at the bottom it bothers me( 1/2 the scroll shows up and my tv screen adjuster can not move it enough) . I am assuming that the adjusting pdf will have the instructions on how to adjust this??? Thanks for any help and it was super easy but be forwarned but please DO NOT take out those 3 screws!!!

Yeah, the alignment/adjustment doc has the directions...

Sounds like it's probably a 2 person job, one behind the TV adjusting the DMD board and the other in the front to tell you when you get it right.

Hi everyone, I have a Samsung Slim DLP tv model #HLT5075SX/XXA, version PD01. This is a different version than what I am seeing on the posts. I have major starlights on my tv....but I prefer to go outside to see bright white stars at night. LOL
I am going to replace the DMD board/panel myself, but I need to be sure I have the right part # for my tv. Can someone provide me with the correct part # and where is best place to order please?
Looking on the internet has me flustered due to the different version #, and I don't want to order if I'm not sure.
Thanks so much, great forum!

Looks like 4719-001981 is the only part I can find listed. samsungparts.com and encompassparts.com both have it for $153 right now.

It seems like most sets only have 1 version number. The models that have two different versions seem to be an abnormality.

Thanks to everyone, especially Pez and Joe, for all their input on this thread. My HLS4676S went from 2 dots to about 50 in a week and is back to a great picture now after the repair, save one small issue.

The right side of my picture is barely higher, like 1 cm, making the image slightly slanted. I don't know if anyone has seen this problem post repair or not. You can't notice it while watching regular tv, and most people don't notice at all. It does bother me when I'm watching something with a ticker or looking at my on screen guide.

I didn't see any "rotation" adjustment in the service menu, and I was tempted to re-do the repair to make sure everything was back in line. I've never messed with the alignment screws and am nervous to do so. If anyone has any suggestions, they would be appreciated.

-Ryan

When they replaced the chip they messed up the alignement, now... unless you (or whoever is going to re-aligne it) have some time to spare, leave it like that if it doesn't bother you, otherwise the manuals that are on this thread, have the allignment instructions but it's not easy or I should say, it is easy but very tedious: The smallest lil movement of the assembly that you need to re-allign represents a huge skewing of the image on your screen. Good luck

Post #166 contains a synopsis of what you need to do to correct this problem.

Hey all...I wanna be in the cool club of white dotters. Actually I don't but I am anyway. So the first one popped up yesterday, and now have 2 or 3 others flickering and letting me know they will be here full time soon. I have an HLS6186W bought in Jan of 07. Spoke with Samsung today, same response...they don't know what I'm talking about.

So my question is, the bulb has like 6500 hours on it. I'm not super keen on doing the whole assembly, but if I buy just the dlp chip everyone here is using am I also gonna be looking at a bulb very soon and also color wheel as well?

I am willing to spend the 160 or so to make the dots go away...but just wondering if it's gonna be another $400-500 soon behind.

Thanks for all the info on here!

I have had the same "white dots" issue that a lot of you have had. I purchased a Samsung 50 inch DLP HDTV in Feb. 2007. Just recently in June 2009, I started having one single white dot appear on the screen. Soon, the one dot turned into more that 50.

To make a long story short, I went through Samsung Customer Service and the New Jersey BBB with no results. The New Jersey BBB told me to file a complaint with the New Jersey Office of Consumer Protection. After filing the complaint with that state agency, I recieved a certefied letter in the mail from the New Office of the Attonrney General. That letter explained that Samsung has signed a Assurance of Voluntary Compliance (AVC) with the State of New Jersey and has 30 days from its receipt of your complaint to reply to you.

If Samsung makes you a settlement offer and you accept, your file will be closed with the State Office. If you do not accept the offer, your complaint will be submitted to binding arbitration with the Alternative Dispute Resolution (ADR) unit of the Division of Consumer Affairs. This is a free service conducted by the ADR unit.

All in all, I was contacted by Samsung 7 business days after they recieved my complaint. They asked be point blank what I thought was a fair deal. I told them that Samsung fixed my TV (parts and labor) at no cost to me. They said OK, provided me with a repair service in my area, and said they would extend my warranty for the one time fix. Within less than 24 hours I have a service tech scheduled to come to my house and fix my TV at Samsung's expense. The repair is to take place in 2 hours from the time of this post.

You have to be patient because the NJ Office of Consumer Protection took about 4 weeks to respond to me. After that the process was very quick. Samsung will fix the "White Dot" problem, you just have to know what route to take with them.

Just remember the New Jersey Office of Consumer Protection.

The Samsung tech arrived at my house on time. He repaired my TV at no cost to me!!!! The picture looks like the day I bought the set. The repair only took 20 minutes.

***FYI*** for all of you out there who are preforming this repair yourselves. The tech told me it is not the entire DMD board that needs replaced. It is only the DLP chip on the board.

GOOD LUCK TO ALL THE WHITE DOTTERS OUT THERE!!!!!!

Nice story... I am glad that for you it went pretty smooth, that was probably due to the hundreds of complaints they received before, they used to say: "White dots....? never heard of it" I guess they must be now aware of this kind of forums on the net.

Yeah... it's just the DLP chip I think that has been strassed on a number of posts on this thread.

Way to go scmichael79 it pays not to give up !

Ok, I have read almost this entire thread.

I only have ONE dot at this point. Its been about 2 months.

I have the HL-S5086W (3 years old) and according to Samsungparts.com I only need to buy and replace the 4719-001981 part. Its $153.

This will solve my issue, correct? Thanks!

PS What do you think a 3 year old model like this with a new board and lamp is worth? $400 ?

I have a Samsung HLT5675SX/XAA, and white dots are all over the screen now, and new ones come every day, usually start as black and then turn white. After reading this super-informative forum, I obviously have a problem with the DMD chip. I was looking at replacing the chip, and using the same board, (as that's what it seems the problem is, and that is unlikely the board is "bad" also.) My only problem is that I cannot find the part ANYWHERE? samsungparts.com or others listed. It seems even the model number is hard to find parts for. Could anyone please help me find where to purchase the actual DMD chip at online? Thanks, so much!

Thanks for all the help. I bought the chip on EBay for $119.00. Fixed the problem. I am not by any means a tv repairman but I fixed it in only about an hour or so.

I have a s4266 that just developed the spots and it looks like trying to resolve it with Sammy is going to be a waste of time so I am going to skip that.

My question is, do I need to replace the board ( and i assume the DLP chip) or just replace the DLP chip?

I read a post about the chip being "burned" - is that what everyone is experiencing? If so I imagine some heat sink adjustment may be in order also.

Thanks guys!!

Hello, To All Forum Members

I replaced the DMD Chip today and my DLP TV is back to normal.
I still love my DLP TV and is well worth spending the money to fix.

Many Thanks to Pez and Joe for all their Ground Work to solve the white dot issue and other Members for their feedback.

It is Greatly Appreciated and save me alot of $$$$ by doing it myself.

I have an Australian DLP TV Model Number SP56K3HX

It has the 1272-5003W DMD Chip fitted which is the same as 4719-001981 made by Texas Instruments.

I purchased my chip from--

Their Knowledge,Service,Pricing and Delivery Time was Outstanding
Many Thanks Mersin.

Also to other Australian SP model DLP Users who wish to access the TV's Service Menu
Put the TV into STANDBY
On the TV's Remote
Push these Buttons in Order
INFO MENU MUTE POWER
I use this to view Lamp Hours etc

Again, Many Thanks to All AVSForum Members for their invaluable information

Ordered and replaced my DMD. Process was low stress thanks to the pdfs and advice here, Everything went back together no problems, TV fired up with no dots. We had a celbratory dinner and sat down to watch the TV we had just fixed and the picture is very bad. There is a problem with picture quality. (fuzzy with some ghosting and odd metalic brightness on colors that do not need it, and we have some thin horizontal bars that are light reddish in color and run from side to side. Any thoughts on what to check? We are going to go back in to check that all cables are tight and secure. Anything else to consider other than that I may havd a dud DMD replacement?

The seller claims that my problems are because of installation. He linked this thread and has stated.

"You have to go thru service mode adjustments every time you replace this chip. More information can be found at these websites:
"drop.io/HLS5086W" and "www.avsforum.com/avs-vb/showthread.php?t=1107926"
It is not a simple procedure."

That is contrary to what is posted here. Is this guy full of BS or is there an adjustment that will remove multiple red/blue horizontal lines and poor picture quality?
