I can't guarantee that it's all 100% the same, but that's the same part as my HLS5086w (PB02) set. If the DMD Panel is the same, then I imagine the DMD board and how it's setup would have to be very similar.


I'll PM you about getting you a copy of the service manual stuff I have.

Be careful since the pin confirgurations on the DMD board to the DLP are different on the PB01 and PB2 versions of PEZ's unit and my unit HLS 4666.

Can you elaborate on this? I thought the part numbers for both parts were the same?

Sorry for any confusion. Our part numbers were the same. What I meant to say was that the PBO1 versions have a different DMD board than the PB02 versions where the pins to the DLP panel are in different locations. I beloieve that the manual you had also showed that the DLP panel for the PB01 version also had different pin locations than the panle for the PB02 version.

I ordered the DLP light panel on Wednesday from Partstore.com and it arrived on Friday ! I was surprised at how little packing it came in - only some bubble wrap around it in a very thin carbboard box !


Will install it next week sometime, and let you know how it goes !

Oh I got ya... I thought you were saying that your set & my set were different, but I get it now.


Good luck on your swap!

Thank You Pez for leading the way.


I'm happy to report my 42" is back with its beautiful picture.



The backordered dmd came in Thursday......just had a chance today (Saturday) to make time to install. Pretty straight forward if you take your time. And you're right Pez...the ribbon cable was a pain. I used a large paper clip hooked under it so I could apply steady pressure to lift it out. There certainly wasn't enough cable to pull with your thumb and finger like the guy in the guide.


Have to admit to crossed fingers when I hit the power button on the remote. She popped on just like nothing ever happened.


Shame on Samsung for not being aware they probably have a bad batch of chips.



Thank you again Pez and Joe. I hope this thread helps others to solve their stuck mirror disease.

Not really a club I'd like to be a member of, but I'm here to sign up. Started today with 1 dot, then another appeared after it was turned off and turned back on. I was halfway hoping that it would cost to much and it was time for a new 1080p flat screen, but I can live with this one if I can really get it fixed for 200 bucks.
Nice to have other people to lean on.

I forgot, but I've got an hls5086w, that I bought in November of 06. Lamp hours are almost 5300 I think so I've gotten quite a lot of use out of it in the 2+ years. Bad news is my bulb is probably not too far behind. Anyone remember the bulb life on these bad boys? My GF called Samsung about it and they said "Yeah, we've had a lot of complaints on that but there is no recall at this time". So a nice way of saying "go eff yourself".

Found a decent place to upload all my Service Manual stuff online:

http://drop.io/HLS5086W
http://dl.dropbox.com/u/16526204/HLS5086w.zip

You can pull down individual files or there is a link on the right side to "Download ZIP Archive" which will get you everything in a .zip file.


"Disassembly Reassembly.pdf" is probably the most important, it's the step-by-step on how to swap various parts.


"Parts code list for each DMD Panel type.xls" is the Service Bulletin about the difference between the PB01 & PB02 models.


"Alignment Adjustment.pdf" has... er... Alignment & adjustment info. Also gives a list of all the service menu options.

Pez, this will be a great reference for the forzen pixel community !


I have recieved approval for full coverage for the repair bill from Visa.


I will eventually repair this unit ... right now my refrigerator is having problems.

I am still wondering why the micromirrors in these HLS units seem to be failing. Based on the research paper Samsung published on accelerated testing, the micro-mirror failure occurs with elevated temperatures. So I would believe that the heat exchanger or the fan cooling the DPL panel is not working properly. Since you have a PC background did you ever check how well the fan was doing after you fixed your unit ? Could be that Samsung saved 50 cents by putting in a smaller fan that just does not have the hosepower to cool the DPL panel. Alternately, if the ambient room temperaqture is 5-10 degrees higher than their design point and the TV is placed in a confined area the heated air may not be cooling the DPL properly. Since I live in FL and my room temp is near 78-80 degrees , that could be significant. Any thoughts on these points ???

Yes, good luck Joe. Hope it goes well!


You'd think something that delicate like that would be shipped in a plastic clam shell like Newegg ships OEM CPUs in.

Just though I'd comment for others that after further inspection I see that the DPL panel has a glass cover built into it to protect the micro-mirrors.

Well, I completed the surgery and I now have a TV that is as good as new. No spots. I'm absolutely thrilled that I was able to get a "new tv" for $200. Thanks to Pez Junkie and Joe Demuth for sharing their knowledge, expertise and manuals.



I have no technical skills whatsoever, but this was pretty easy with the instruction manual. It probably took me 1.5 hours from unplugging the tv to powering it back up. I took my time too. If you have a wife/girlfriend around the house, it will be better to have her help you with some of the small wire disconnections....and to just have 2 sets of eyes looking at the instructions and the components.


Again, thanks to all. This made my weekend!

Mine just looked at all the TV parts and shook her head....



But she sure liked the result.



Thought I'd throw some pics up for anyone that's interested. Various shots of before, after and what you'll see inside the TV.

I think so. I've got a service manual thing that I can share with step by step directions and pictures. It's mostly unscrewing a bunch of screws and unplugging a bunch of cables.


The worst part for me was getting the little ribbon cable plugged back into the top of the DMD board. (It's the only one that doesn't have a little plastic clip thing on the end.)

For the record, since previous posts mentioned the trouble with the ribbon on top of the board (disconnecting and connecting it), I chose to leave mine in tact during the replacement. If you have someone to hold the metal plate that covers/protects the board, you can just swing that piece up while you are replacing the DMD board. It was no problem, and once you get in that far, it doesn't take but a few minutes. I thought I'd give this a shot to avoid the known trouble that came with disconnecting the gold ribbon.

PexJunkie,

You have given me hope for my HLS-4266W.

I had already disassembled the three main boards and had photos ready to try auctioning parts on ebay.

My set started with the dead pixels (white) last fall and I replaced it with an LCD.

This would make a good second set if I could fix it for under 250.


Where can i find the PB01 versus PB02 info to deterime which DMD I need.

PEZ AND JOE, you have been a big help, I'm also going to try this. First, I have HLS4676Sx/XAA, Version PA01, will the manuals you have online work for this model as well. I went the the Partstore and Samsung parts store and I come up with a part # BP96-01670A. Would you mind verifying this is the correct board. Thank you in advance.

BP96-01670A is a DMD board. It has a socket where the DLP chip (DMD panel) plugs in, but it does not include the DLP chip. If you're having the white spot/stuck mirror problem, then that is the wrong part.


On either of those sites, go to the list of all parts for your model and search for "DLP". The part that shows up when I look is 4719-001981. (same as the PB02 version of my set.)


The DMD board listed for your TV appears to be different than the one for mine, so the directions from my TV may or may not be helpful... I can't promise anything.
