Samsung DMD board replacement - Page 19

nozlep, your pic points to a dmd board failure.

The technician came today and cured my set of its "pixelpox"



Seems Samsung has a significant back order problem with the replacement parts.

anyone has the step by step procedure on how to replace this thing with pictures? i looked through 19 pages of this forum and did not find one.

samsung sucks!

I just replaced the DLP chip (4719-001981) in my HLS5065W to get rid of the white spots on my screen. When I turned on for the first time the screen is out of focus and fuzzy. Does anyone have an idea of what I may have done wrong?

Post #240 from AmitinLA seems like the same issue. Any help would be welcome.

Thanks,

3 SCREWS PINK CIRCLE = ADJUSTING SCREW ( DO NOT EVER TOUCH!!!)

"during disassembly i noticed the 4 screws with black arrows have different torque. 2 screws on top are tight. 2 in the bottom are not . i measured the gap and put them back the way they were." not sure if that has anything to do with the alignment. but it wasn't mentioned on the manual to pay attention to that screw. its just weird how they didnt have the same torque.

did you touch the 3 screws mentioned earlier?

so i have all these issues with the white dots and all...

thing is that im in the army, and stationed overseas.. so i would assume they have techs here or will they only send techs out if you live in the states? with that being said, then they would have to reimburse me then ?

and untill i have some some of the peoples here, i thought mine was bad but its getting there anyway ... ugh ..

and can someone point me in the direction to get the service menu ? been lookin just havnt found it yet..

thanks

also when i went to the site to see even bout ordering the part, the part number i found on the site says its for the PB01 version and i have the PB02... so someone help me out on the part number for mine?

model # HLS5086WX/XAA
serial# B18E3CELA02260D
version PB02

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.

Have you tried contacting Samsung? They should fix this for you... but not sure how that works with you being overseas.

Also, in case you haven't found it, the service menu works like this:
With the TV turned *off*, press MUTE, 1, 8, 2 and then Power. You will have the service menu on screen until you turn the TV off again.

yea so i talked to a few people .... first couple times i was on hold for well over 45 mins .... but then i finally i got someone that was somewhat helpful, and tried explaining to them that all i need it the part and i can fix it. but alas their answer was " well we need a tech to come out there to see and make sure thats the problem"... yea i cause i want to deal with the playing "where is Orion today"... but then i figured i would just say F it and buy it, and turns out... there is over a 4 week delay in that even .... and im suppose to deploy in a couple weeks. so much for being able to watch a little bit of tv ... thanks samsung for helping out the service members!
oh yea, tried the german route, figured that would be good. turns out, none of them speak english ... pfft yea right!

so where do i have to go to get put on this class action ? cause im all bout this now... and after this, i will not buy samsung again... especialy with this problem and then the damn cam i have of theirs too! a $350 cam and pretty much out of box brand new and i have a line from top to bottom on my lcd screen.. and the pics turn out grainy too... and its a 10.1MP!!!! wtf .... never again i say!

oh also thanks pez, it worked... and looks like i got more use out of mine then most cause the most i have seen was bout 4300 or something like that, and today when i checked it was 5407 hours... so not to bad, but also thats with atleast 2 to 300 white dots tho ...

Just wanted to post my experience today in calling into Samsung Executive Customer Relations (ECR) Team.

I got my first two white dots this weekend and found this thread. By the time I got to the end I learned Samsung would likely help me out despite being out of warranty for 21 months (HLS5086WX/XAA PB02 was purchased March 9 2007).

So all went well. I got my service order # and they will be paying for parts and labor. I should expect a call from local service center in 24-48 hrs.

I'll update everyone once work is complete and final results.

Service menu doesn't delete TV settings (like picture/sound/channels) unless you specifically choose RESET DEFAULTs command right?

ok guys... Just found this thread.


Have a HLS5686WZ/XAA purchased in Nov 2007, and the 1st white dots showed up about 2 weeks ago. Now we're gaining one new dot about every 3-4 days.

Service menu shows 5912hours (original bulb!)


Per the advice I found here, just got off the phone with 1-800-Samsung.

She took down my model #, and S/N and gave me a transaction #. Will have a local service company call to setup an apt in 1-2 days and "if it is the fault of the board the cost of both Labor and Parts will be covered by Samsung"


While I'm not happy it's occurred, so far I'm happy with their response to the issue.

kinda blurry. it looks better in person.

FYI - Samsung tech came out this morning. Took one look at the TV, flipped it around and took off the back panel. About 5 more minutes of pulling shields off and he swapped out the DLP chip, and put it back together.

15 min later my TV was lookin' nice and new and dude was on his way. Nothing to sign, no charge, no complaints.

Again, not happy it happened, but Samsung certainly stood up for it.


FYI - he stated that Samsung is sending the offending DLP chips back to TI, and that for the time being he didn't have any information to say I shouldn't look forward to this happening again in another 2-3yrs, but he wasn't real sure.

So, over the past few days, I gained a few more dots for a total of 5. My DMD chip was replaced today for free. Looks great. Everything in focus.

Checked original lamp hours: 8337! This TV was purchased exactly 3yrs ago this month. I have been babying the lamp by minimizing on/off cycles, or periods of ON time less than 30/60mins. Also, I never turn the lamp back on until the fan stops cooling it after shutdown, and usually at least 5 mins past that. Of course, I have my trusty APC BR800BLK Back-UPS to ensure that the lamp never gets abruptly powered down without proper cooling down cycle.

I can not find any links to a pdf file to take apart my 50" Samsung rear projection TV. Yes it does have the white spot sickness.

Samsung is fixing white spots as warranty repairs now... try calling Samsung first.

(btw - all the documentation I have is here: http://drop.io/hls5086w)

Thanks you PezJunkie - that's a really useful collection.

PezJunkie and everyone that contributed, I just wanted to say Thank You soooo much for the helpful info. We bought our TV used about two months ago and now you cannot hardly even watch TV. I have called Samsung several times and they say that my TV is covered under their white dot issue, but then the technicians call and say that it is not, then Samsung informed us that our model was not one of the ones that had a faulty chip (HLT5676S). But abviously it was, otherwise there would not be hundreds of white dots on my TV screen. I give up, so we are going to buy the chip and install it ourselves. Anyway, THANK YOU!!!!

nonono...it is covered...we r Samsung auth.
call Samsung and have the call elevated to their ECR dept.
They will approve it.
R U in So. Texas ?
alan

Just call 1-800-Samsung and they will send out a service tech to fix it for free.

I would like to thank PezJunkie BIG TIME

Here is what I had to go threw.

My Tv is a HLS5086WX/XAC

Ontario Canada

After 5 Day's of reading and reading this post I came to the conclusion that I had the same issue as all of you got here. So bad that it looks like bar codes on my Tv screen with over 1000 black dots & 2 white ones with lines running right across the screen left to right every 4 Inches.

I took the DMD chip out to take a look at it and yes what you see on the chip is what you see on the Tv screen dot for dot, clearly a burnt DMD chip.

Now with samsung LOL

Called them the first time and with no go they told me my warranty is up so there is nothing they can do for me so I was determine so I called them the next day with the same answer nothing they can do. I let it go for a few days and had every thing ready this time and sure enough I got someone that said yes that it is a well known problem and that samsung will send a tech over in 24 Hours. The tech just called and a appointment is set cant wait. I will let you know how it turns out from here with that.

Samsung will cover it don't give up he said the new reps are not aware of the issue so that's why they give you the blow off.

So my hlt-5075sx galaxy of white dots are doomed. Called 1800samsung spoke to a rep and everything got squared away on my repair order 'for freee'.

Local tech calls me the same afternoon to confirm my address and time he can come over to resolve the 'white dots'. He has the part in stock and knows of the problem.

Wow great response time. We'll see how it goes tomorrow.

yes! lakers win and white dots gone tech took only 10 mins to swap out the dlp chip.

I have the 67" model from Costco Model #HLT6756WX/XAA. I spoke to 2 cust service reps who said the model was not covered for the free fix and that I would need to pay out of pocket for repair and parts. I am guessing that this is because Costco has its own specific Model# and that in the past Costco has often honored replacement outside of warranty period, which is not a common practice anymore. I am checking and awaiting call back from Costco, but it really isn't on them so much as Samsung IMO. Same damn defective chip.


Tried this on my second phone call to customer service and was connected to a rep in the Executive Customer Relations Dept. I was also told that my set would not be covered and that there was nothing more that could be done and that this is the highest level that I could reach.

Hmmmm really? Well that sucks. Left an email with my complaint and related that if a resolution could not be found for my situation (Same damn defective chip) that I would file a complaint with the BBB, for whatever that's worth and I will not be purchasing any other Samsung products.

Definitely sucks on a TV that was $3K new.

Edit - And yes I just lurk and read and don't post.

Almost, but not exactly. It looks like the DLP for your set is a different part number.


Complaining to the BBB is good too, but it looks like people have had better results filing a complaint with the NJ state attorney general's office.

Good luck!

very interesting that now over a year later Samsung is fixing these for free.

I paid $200 for a new chip and replaced it myself, glad the later sufferers of white dot disease are getting fixed...but Samsung, you should review your files.
