Samsung DMD board replacement - Page 27

My HLT5075S started exhibiting this issue about 3 days ago. At first it was a single dot, the next day a couple more appeared. By day three I was up to 11 white dots. I was afraid that Samsung would have long since discontinued this campaign to replace the DMD chip for out of warranty DLP sets (especially a set purchased in 11/07). Yesterday I used the web chat support from the samsung website to report my issue. I simply stated that I had an increasing amount of white dots on all inputs/channels and that from my research this seems to be a known issue in which Samsung has replaced the DMD chip at no charge, even for out of warranty sets, in the past. I then asked if anything could be done for my set. The tech simply asked for my serial #, and then pasted me the same canned response I've seen in other postings regarding a one time replacement, and that I would be responsible for the service call charges if it was not related to the DMD. I obviously happily accepted these terms, and am now waiting for the repair center to call and schedule my appointment. As long as the repair goes well, I will be very satisfied with Samsung's response to this issue. While I *shouldnt* have to buy a new TV after only 5 years, Samsung could have easily told me I was too far out of warranty.. I guess I am fortunate that my set lasted this long and that all of you paved the way for an easy repair for me!

Thanks Samsung!

Good luck!

They came and did my hl-t 5076 at no charge last year. Now I get a few more years with a lousy color decoder... Someone won't let me buy an external video equalizer...

Replaced my dmd chip myself today in about an hour. Tv works fine now. Bought on amazon. Samsung left me out in the cold.

I just wanted to say that I did the same, I had the "white-dots" problem, and purchased 4719-001997 DLP Chip through Amazon from ShopJimmy.com for $165. Replaced my chip in about 30-45 minutes. I have a Samsung 61" LED DLP model #HL61A750A1FXZA.

The screen quality afterwards looks great. Didn't even require any adjustments after putting in the new chip.

I would say the technical skill required is about a 4/10. Have to make sure you are careful to unhook everything as you are pulling off the cover, etc from the board, but there really isn't much to it. If you have ever replaced a processor in a PC then you can definitely do this.

Samsung just fixed my television today! FREE.

I have the HL-T5075S and started getting the white dots about 1-2 months ago.
It finally got really bad, maybe a hundred white dots, so I started searching on the internet for a solution.

Finally I found this board and learned that others had this problem and that there had been a class action lawsuit at one time.

See link
http://www.samsung.com/us/dlptvsettlement/

So on Friday 11/9/2012 I called Samsung's customer service.
I told them I had a Samsung tv that I really loved, but that now it had lots of white dots on the screen.

Also I mentioned that I had read on the internet that other people reported the same problem. (I didn't even mention the lawsuit).

They asked me:

- For the Model # and Serial #, which are on back of television, easy to find,
and
- If I had tested the television on different devices to see if the white dots showed up in every case

*I had all this info ready when I call. In fact, the rep thanked me for being prepared and said often it was frustrating trying to help people who didn't have this info, that it usually took 4 minutes just to get the serial and model #s.

The customer service person said he would order a one time free repair, and would arrange for a technician to come to my house. The rep said he would ask them to rush it, and I would get an email and a phone call regarding service.

I got an email within 24 hours and a call Monday 11/12 from the technicians to schedule the appt date and time. They even worked with me based on my schedule, so that I didn't miss work.

The technician fixed the tv today 11/16/2012 around 12 noon.

My tv is working just like new now.

I would NOT have asked for and gotten this repair if I hadn't read about it in this avs forum.
THANK YOU SO MUCH!

I have model HLT6156WX/XAA for which I have ordered a new DMD chip. Can someone advise the best thermal pad or thermal compound that I should use when installing the nwe chip?

I am glad that Samsung is now reluctantly agreeing to fix some of their crappy TV's. To all of you who get your TV fixed by them, do not be so quick to praise them. Take a look at how long this thread is. Most of us early guys got the shaft by Samsung, after arguing and complaining to them. When they said no to us, we had a couple of choices: throw the piece of crap away, which some did, pay someone to fix it, or buy the part our self, and fix it. What a hassle. They are not a good company. They did not stand by their product when they should have.
The repair job is not that bad, but nobody should be expected to have to make that repair themselves. I have bought a few smaller TV’s for other rooms since this issue, and you can bet you a$$ that none of them have a Samsung label on them

Just posted this as a new thread in this subforum, didn't catch this thread until after. Reposting it here -

So, I'm another Samsung DLP owner that has recently been stuck with the "white dot" issue. I've contacted samsung and got the dreaded "normal wear and tear" response. I gave Samsung a little piece of my mind after learning about how many people have had this issue when I googled it. Blows my mind they can get away with this excuse knowing that this DLP chip is clearly of poor quality and/or defective.

Since Samsung has refused to help me in any way whatsoever, I've done the research to replace it myself and found this chip and this guide (which isn't my exact model but I'm hoping the process is similar).

Two questions:

1. Is this the link I posted above the correct chip (my model is listed in the decription for this chip), and if so - is this item of acceptable quality/price?
2. Is the guide I've found a close enough model to be able to replicate the steps myself with my model? (video is a HL-T6187S, mine is a HL50A650)

I'm pretty tech savvy, I build alot of PC's in my spare time and have disassembled the TV before for lamp replacement, so I'm not extremely worried, just wanted to get some expert advice here from people who may have been through this before.

Thanks for any help!

Hello everyone.

Just got off the phone with Samsung's Executive Customer Relations after calling and getting no ware with the 1800SAMSUNG number. My hlt6189sx/xaa is starting to get the white dots of death. Samsung said they will not cover the repair. So I plan on doing it my self. But after searching for a while I can't pin down a part number for the exact DMD board I will need to replace the bad one in my set. I have come across this one on ebay and it does say in the list my TV is compatible. Just wanted to check with you all and see if it is indeed the correct chip.

Thank you all so much in advance for any help.

On a lighter note I replaced the bulb on my 50" Samsung DLP 2 months ago and checked the hours on the original bulb and it was at 11,243 hours! And it still works, so I have a back up bulb.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!, I bought a Samsung 56" DLP TV and shipped it to Jamaica (WEST INDIES, Caribbean), where I live.

I now have white spots that turn black after a while, can someone tell what DMD DLLP chip i need to buy for Model #T5675S

model code # HLT5675SX/XAA and where I can get to purchase it online

My TV now looks like millions of tiny insects are trapped in the screen.

Here's some on ebay:

http://www.ebay.com/dsc/i.html?LH_TitleDesc=1&_sacat=0&_from=R40&_nkw=HLT5675SX+dlp+chip+-lamp&_trksid=p2045573.m570.l1313&_osacat=0&_odkw=HLT5675SX+dlp+chip

Good luck!

Thanks a lot, do so need that luck, hope it works.

I did some research on what my problem was and came to the conclusion that it is def the DLP chip. Well, honestly I figured I was screwed bc of the bad things I read on the forums and such that the customer service was horrible and Samsung offered no resolution. But finally I figured, why not just try anyway...so I did. I chose to do the chat option for the customer service. It was short sweet and to the point. They are sending someone out for a one time free fix. I'll provide the transcript for you guys when they send me the transcript. IfI your having this problem...at least give it a shot. The worse you will hear is no, we can't help you. In my case..they said yes and I am happy happy happy

I am very glad I kept an eye on this forum. I was soon going to trash the unit and just replace it since new TV's are getting cheaper.

Thanks everyone.

Just did the same thing.

Reported Thursday. Fixed today at no cost!

Thanks!

I also got lucky and fell into this forum. I bought the chip to install myself then just now found out it will be covered by Samsung and they will be calling tomorrow for a service tech time to do the repair. Mine is a HLS5686WX/XAA model and they are still covered for this issue..

On another note.. I had a new color wheel and bulb waiting to go in as my wheel has been humming pretty good for over a year now off and on. Starts humming initially then goes away. Mainboard was replaced (he gave me a new bulb too) under the service contract with the retailer when it was 2 yrs old. It's coming up on 7 now and the white dots just started last week. Must have been a good run.. Getting the stuff I have installed along with the repair should nearly make it a new tv again..

Thanks to all on here for the help and ideas.. It is what makes these forums the things they are..

Griz

just following up: my unit was repaired yesterday at no cost and it looks great. Thanks everyone.

Tech showed up on Friday afternoon right on time. Did the DMD chip replacement and put in the color wheel I had on hand. No more dots from the chip and no more whirring sound from the color wheel.. And the set picture looks like it did when I got it.. Awesome pic in it now. Amazing what some cleaning of the lens will do I guess..

Thanks to everyone who contributed to this forum and writeup. You cats are the best..

Griz

I got a new DMD chip if anyone wants one at a good price..LOL...

I am seeming to have some trouble finding the DMD chip for my tv. I think because it is a canadian verson..

Would anyone be able to confirm the part number for my Samsung hl-T50768 / model code HLT5076SX/XAC DLP?

And if they have any tips on places with good prices, that would be dandy.

Thanks for this guys, i actually really love this tv except for this issue.

Did you check out post #795 in this thread? You might call Samsung and see if they will replace yours for free like they did mine and it is an older model than yours.. If no help from them, we can find a chip or something for it I am sure.. The one I have may or may not work for you as I have a spare..

Hi everyone. I have a Samsung 67", model: HL67A750A1FXZA. Tried calling in, escalated and got nowhere. I went from one spot, to now having six.

What do I need to buy to try this repair on my own? So disappointed that the tv is failing.

Thanks so much.

The stuck pixels began to appear on my HL-T5075S last week. Started with two white pixels and added a third last night. I found this thread and gave Samsung customer service a call. They are sending a tech out to replace the DMD chip at no charge to me. We shall see what happens.

Don't feel bad, I have over 30 DLP projectors on hand - ALL WITH FAILED DMD's manufactured by TI - And TI claims they are more reliable then LCD's? What a joke, there are currently hundreds of projectors and big screen TV's for sale on E-bay with the WHITE DOT problem. There is no doubt in my mind that TI knows that they have had an ongoing problem for the past 4 years but it appears they are not doing SQUAT to fix the problem. They do continue to BOAST how reliable the DMD device is - I think its time for the LAWYERS to put them in their place. The projectors I have with bad DMD chips are Dell, Mitsubishi, Viewsonic, Optoma, and NEC and they are all LATE MODEL projectors from 2008 to 2011

Looks like Samsung will help with only certain models even though the problem is the DMD chip when the white dot problem occurs.


You are now chatting with 'Bobby'. There will be a brief survey at the end of our chat to share feedback on my performance today.
Your Issue ID for this chat is AVAFYXQF50JNE.
Bobby: Hi, thanks for reaching out to Samsung Technical Support. How can I help you today?
You: Hi Boibby, I own a dlp tv model # hl67a750a1f that has a problem with white dots in all display modes. I am out of warranty but understand that there is a one time out of warranty fix being applied to owners of these sets
Bobby: Sorry to hear that. Let me see what I can do.
Bobby: Would you mind holding on for a few minutes while I check the required information regarding the issue?
You: su re thing
Bobby: Thank you for waiting. May I know how long did did you experience this issue?
You: it started a year ago with a couple of dots now the screen is full of hundreds of dots
Bobby: I see. Is this the first time that you contact us regarding the issue/
You: I made an attempt a few months ago
You: It was by phone with no results. This is the first time by live chat
Bobby: I see. May I know what happened?
You: I just went around and around with no satisfying result
You: With no results I turned to the internet and forums and realized that this is a major problem with Samsung DLP's
You: Several members on the forums have gotten their problem addressed and fixed by talking with an agent on Samsung live chat
Bobby: Sorry to hear that. Okay. May I know if this issue happened on all sources?
You: Yes
Bobby: May I know what types of cable or connections are you using and what devices are currently connected to the TV?
You: I have a DVD and COX cable box. All cables are HDMI cables of the highest cost
Bobby: Thanks for that information.
Bobby: I have checked my resources here and after thorough research, it was determined that only specific models exhibited a slightly higher-than-normal failure rate. Although your TV has similar symptoms, research indicates that this is due to normal wear and tear.
You: I would not think that normal wear and tear would happen on a 3 yr old $3000 DLP TV
Bobby: I understand. Our engineers have determined which models have the particular parts that tend to fail at a slightly higher-than-normal rate. These are the only ones that are being covered outside of the warranty term.
You: The DMD chip seems to be the culprit. Am I right?
Bobby: 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.
Bobby: Please tell me if there is anything else that I can help you with.
You: Can you give me the part number for the DMD chip.
You: S/N AKWG3CKQ701265A
You: Model Number HL67A750A1F
Bobby: Sorry for the inconvenience but we here on Live Chat don't have information regarding the part number of the DMD chip. I can't promise you anything but you can try to call J & J International, Inc. our authorized dealer of parts and accessories and check if they have information regarding that. You can reach them at: 800-627-4368 ( Mon - Fri 9:00 AM ~ 8:30 PM EST ).
Bobby: Please let me check for a minute on there website.
Bobby: Thank you for waiting. Here is the link to there website where you can see and purchase the chip. Just click the link below: http://www.samsungparts.com/Products/Parts_and_Accessories/PID-4719-001997.aspx?model=HL67A750A1F
Bobby: You can also call the number if you have queries on the part or accessory that you want to purchase.

I too have the dots of white death and was told at first it was covered and then it was not covered. My model number is HLT6156wx/xaa. Please how can some be covered and some not if it is the SAME part in all of them. What can we do? This is an obvious defect!

Class Action Lawsuit anyone?
Edited by Mary Fisher - 3/7/13 at 9:29pm

What is your model number?

Mine is an HLS5686wx/xaa which would be older than an HLT I believe.. Odd how some qualify and some don't..
