White dots on my Samsung HLT6187SX/XAA

by matto227 / October 29, 2011 5:32 AM PDT

I am getting the issue with the white spots appearing on my screen. Initially it was only one or two, then quickly spread to more than 30.

The service tech assigned to my transaction called me and said it would cost me $440 to repair. He said for my model, it's not a DMD board/chip, but the DLP chip that needs repair.

I just posted on the Samsung Support form on Facebook. Hopefully, I will get a response.

In reply to: Update

I'm not an expert, but I have done a lot of reading on this. I believe many people are using the terms DMD chip and DLP chip interchangeably. DMD apparently stands for digital micromirror device. DLP stands for Digital Light Processing. However, according to TI's DLP site, the DLP chip:
The amazing DLP chip consists of up to millions of tiny, microscopic
mirrors which reflect light, digitally to create a stunning image.

That sounds like a DMD to me.

I got a reply this evening.

Basically, I have to pay. I have a LOT of Samsung products, some of which are getting to be 3-4yrs old. Should I expect them to start failing now as well?

I suppose I should replace my receiver and my two older Blu-Ray players with LG products now.

Samsung purge

In reply to: Not much help...

Yes!!! I think you should get rid of all your Samsung products... Just had the wonderful experience dealing with the Samsung support about white dots on my 4 year old tv. "Normal Wear and Tear" That translates to: It is normal for your Samsung product to fail in 5 years from your purchase. Unfortunately I have some major appliances I just got that need to go on craigs list ASAP!! Now that I've been snapped out of the Apple like trance with Samsung, I can't believe I ignored LG! They've got some great stuff.

White Dots - new chip or used
by danwdooley / January 14, 2012 9:32 AM PST

I hope my experience is a fluke and not the norm. I ordered the replacement DLP chip from Samsung Parts. $278. Got it and got around to the process of replacing the bad one this morning. My TV had to this point seven spots. Put in the new {?} chip and this one had 50 to 100 white spots all over the screen. Removed it and thinking perhaps I had gotten some dust particles on the surface of the micro-mirror section, checked it plus the mirrors in front of the chip. Clean. Of course dust specks should create shadows and thus dark spots, but anyhow.......

I've been an electronics field service engineer all of my career so should be able to handle component changes (will Samsung TS presume I did something wrong with the installation? Hope not) so put that new one back in and still the starry skies. Put the old one back in and back to my original seven spots.

I can't believe a brand new DLP chip would start out so bad. Did they send me someone's defective return? I will call them Monday and hopefully I can get a good one. Just hoping that this is not a normal expectation when getting replacement parts.

Same run around
by kicking35 / May 23, 2012 9:56 AM PDT

I have the same issue with the HLT6187 and Samsung states that they have never heard of the issue with this model. I see from a lot of posts that this is a standard response. They insist that they have not heard of this problem before on this model. I even got the extended warrenty that just expired a few months ago. That was a waste of money.

I will be curious to see if they respond to you.

Update..."Normal wear and tear"
by kicking35 / May 23, 2012 10:12 AM PDT
In reply to: Same run around

Samsung insists that this is normal wear and tear for this model. There response was
"The part that has appears to have failed in your unit is not the same exact part that has been determined to fail at a higher-than-normal rate, even though the visible symptom is similar. The symptom can help indicate which part needs to be replaced, but it doesn't mean that the particular part was defective from manufacturing. Any parts can fail after time as a result of normal wear and tear."

Unfortunately I bought 4 Sumsung TVs and DVD players. I am hoping that these will not be going out soon.

"Normal wear and tear"?
by danwdooley / May 23, 2012 12:23 PM PDT
Angry Well I hope not. Anyhow, it's been over four months now since I replaced the chip in mine. Still running fine with no more white dots. Let's hope I get at least several more years before the "wear and tear" shows up again.

Oh, I should have noted, I did call and received the replacement chip and when it was installed, no more white dots. So the one they sent me intially was bad. I have the sneaking suspicion that it was a used one. Probably a defective return from some other customer. No proof and I won't insist that this was the case but who knows......

White dots on my Samsung HL-T6187SX/XAA
by bwflorida / May 23, 2012 1:03 PM PDT

danwdooley: I have the same TV with the same white pixel problem.

Can you tell me what part number to order?

Can you get the part from other suppliers for less than $278?

I'm not planning to install it, I'm just thinking about buying it and then finding a TV techie to install it, thus avoidimg Installer markup.

I'd appreciate your thoughts on this.

DLP Chip Part Number
by danwdooley / May 24, 2012 1:45 AM PDT

Well darn, I knew that would happen. Confused I receive so many emails here that periodically I end up pruning old ones out. Especially those which I think I'll probably not need to refer to again. Seems like every time I do that, a short time later I find I need something I have deleted. Within the last couple of weeks I deleted the email correspondance I had with Samsung regarding the sale tranaction of that chip.

At the same time, I know I did print out my copie. I just don't recall where they are right now. I will be looking for them though. In some file folder somewhere around here. I'll post that info when I find it. Sorry I don't have it now.

On the Samsung parts web site, which as I recall is separate from the Samsung support web site, it will be listed as the DLP chip. There is another item which is actually the whole circuit board. The price of that is slightly less than (as I recall, or maybe just slightly more) the individual chip. As the board does NOT come with the chip, both items would be needed but as the problem is most likely to be just the chip itself, the board is not needed.

As to buying the chip and having a commercial TV tech to install it for you, saving the parts price, I suppose that is possible. It will just depdend on the policies a particular TV service outfit has in regards to those things. Since they're not supplying the chip themselves, they may have a policy against it because of potential quality and recall complecations. I don't know. Never hurts to check. Of course if you have a contact who is technically inclined, he or she would have no problem getting into the TV to replace the chip. Good luck on that venture.

Found it

In reply to: DLP Chip Part Number

Well, just goes to show, my filing system leaves something to be desired. Happy I found the copy of the receipt for the part. The source is J&J International, Inc. The web site is

The PN is 4719-001997. Called: "DLP Chip W/pins on the bottom". Came to $275 with shipping. There was also an RMA for the return of the old part and a core return value. Don't recall how much that ended up to be when the part was credited upon return to them.

Orlando Area Quote For Replacing A DLP Chip
by bwflorida / May 24, 2012 5:20 AM PDT
In reply to: Found it

I just got this estimate from a Samsung repair shop located about 22 miles away:

Trip and labor: $219
Part: $247

Labor: $179
Part: $247

I'll probably have them do the in-home repair, since it appears I can't save money buy buying the part myself.

Thanks for taking the time to reply!

Louisiana area quote

I was quoted the following though they said they could not give me the exact amount (it is their coverage in case it cost more).

Trip and labor: $105
Part: $290

I don't see how I have a choice than to pay it or deal with the continuous loss of dots on the screen.

I'll tell you in a couple of weeks how the repair goes.

Just fixed my HLT6187sx/xaa

In Reply to: Can you lst the steps taken? by jciarrocchi

It's pretty easy if you have a little know-how. I'm a Navy electronics tech so I know the "do's and don'ts" when it comes to working inside a TV. You don't want to get shocked so make sure you unplug and let it sit the night, and then stay away from the power supply. Take the advice on the link and wear the gloves, this helps if you inadvertently touch the chip or lense. My set was slightly different (fan in a different location in front of the DMD chip, but all in all, just follow the instructions on the link. Shop around for the chip online (I paid $178). Here is the link R. Proffitt posted on an earlier link. Good luck!

My 61" Samsung is Model Code HLT6187SX/XAA has white dots
by stephotary / August 17, 2012 4:19 AM PDT

I called Samsung and was told that my model number HLT6187SX/XAA is not on the list of models that have the "white dot" issue. When doing a google search there are complaints all over the internet, same model number, of people who have this issue. The Rep, Ann, told me that Samsung could fix the issue but that I would have to pay for it. I told her that I wanted to escalate to the next level and speak to a supervisor. If Samsung says that this model number is not on the list then they need to add it to the list because this is a known issue and there are many complaints. I was transferred to supervisor, Abbey. She told me that based on the model we have, even though we are getting the white dots, it is because of normal wear and tear.
My comment back is that what she is telling me is that Samsung TV's ONLY LAST 4 YEARS.
My 61" Samsung is Model Code HLT6187SX/XAA, Serial No. AHEK3CKP802579E.
I was transferred again to the next level up the Samsung chain. Terrence finally answered after a lengthy hold (so far it is a 25 minute call and still ticking). Again I am being told that Samsung is not offering any accommodations for this model. The warranty only covers a certain length of time, 1 year. This is not a recall issue and the only thing they can do is set up service for us, assign it to a service center, Complete Electronic Specialist. So, bottom line, they are claiming this is not Samsung's issue, this is my problem along with all of the others who purchased a Samsung TV. BUYER BEWARE. NO MORE SAMSUNG PRODUCTS FOR ME. I WILL STICK WITH REPUTABLE MANUFACTURER'S. IF Samsung comes through in the end and stands by the quality (or lack of quality) I will post a comment stating that they took care of the issue. BUT AS OF NOW, SAMSUNG IS SAYING I HAVE TO PAY FOR ANY REPAIRS DONE BY COMPLETE ELECTRONIC SPECIALIST. MY COMMENT BACK IS THAT I WILL NOT SPEND 1 CENT TO REPAIR THIS TV OR TO PURCHASE ANY SAMSUNG PRODUCT.
Escalated up the ladder 3 levels. Got a call back from Kenneth at Samsung Customer Relations telling me that Samsung will not help with this issue and that to repair will be at my expense. So when looking at all of the beautiful new screens from Samsung come back and take a look at what you get after the warranty runs out.

My 61" Samsung is Model Code HLT6187SX/XAA has white dots -
by danwdooley / August 17, 2012 7:01 AM PDT

That was the same response I received to my inquiry to Samsung. Of couse, as you discovered, the problem DOES occur on your model number and the fix (provided you get the correct part for your model) will fix it. My has remained trouble free since I replaced the item in mine.

The best thing to do is, if you are comfortable and technically able to do the part replacement yourself is to determine the correct part number for your model and put it in yourself. If that is not a option, then using a profesional TV repair service will be your only option.

One thing to look out for. There is a risk that you may receive a defective or pre-used chip. The first one I received turned out to be worse than the original. The original displayed 7 or 8 or so spots. The first chip I received displayed a hundred or more. Like a stary sky. I got an RMA from them and had another one sent and that one was perfect and still is.

"4 years"? I am sure they can last a lot longer than that.

White dots on my Samsung HLT6187SX/XAA
by bwflorida / August 17, 2012 10:46 AM PDT
I have the same set, had the same problem, got the same response from Samsung. There's no doubt that Samsung should have stepped up and paid for this repair... but I love that TV so I went ahead and got it fixed, The In-Home repair cost $466 ($247 for the Part, plus $219 Trip and Labor). The tech who did the work said he had fixed about 12 or 15 sets with that problem, and had not had any call-backs, so I'm hoping the new chip will last longer than the original one. Like many others here, I'm was mad-as-hell that I had to pay for this repair after just four years, but I can't see wasting time being pissed off about something I can't do anything about. Would I buy another Samsung? Why not... it's the best TV I've ever had, and if you divide the repair by four years, I spent just $116.50 per year enjoying the terrific picture that TV provides.
