Replace DLP Chip On Samsung HLT6187




What do you think about this video?

James Hall: I had white dots for a few months, today my screen wont come on... is this 2 seperate problems does anyone have any idea?

Jason Sugimura: I want to express my gratitude for this video! I've replaced parts inside desktop & laptop computers but never inside a TV. Bought the replacement chip online via ShopJimmy for $179 including 2 day shipping and a 20% off discount code. My TV is the HLT6187SAX/XAA model so its disassembly/reassembly were both different (but not extremely) from the video. My biggest issue was removing the board to get to the chip. My TV model has a small wire assembly that plugs into the top right of the chip board through a hole in the unmovable metal casing. I bought and downloaded a service manual which unfortunately turned out to be zero help. To resolve, I ended up loosening a plastic hood over the interior cooling fan to get to the offending wire assembly. After that the rest was easy and I successfully completed the chip replacement. THANK YOU!

WdnUlik2no: Just wanted to drop back in and say thanks again for your excellent video. I finally did my replacement this past weekend and everything went great! Some of the connectors on my HLT6187s were slightly different than what you have (like the monitor cables), but I was able to figure it out since they were in the same general location. My picture looks great again, and you saved me so much money by not having to pay a repairman!

bigtorque: howd you get the board out ? I got to 4:57 then all of a sudden youre putting in the new chip .

WdnUlik2no: I usually buy my parts from Samsungparts com. But this chip is running nearly $400, I see the same chip on Ebay from a seller for $189 who currently has a 99.4% feedback rating. Where did you get your chip from and how much did you pay?

Ken Jorgenson: Bought a new chip for $50 through ShopJimmy.com. This tutorial goes through the specific steps far too quickly, and is missing a step just before removing the old chip. The loud music is distracting. Other than that, it is very helpful - thank you.

Jordan Grosh: Good video, except for the music. The music made it almost impossible to watch. 

sproulman1: my samsung hlt6187 had 50 white dots. i got new dlp chip which had no. 1910-6143w on chip. after taking old one out it had different no.1910-6103w. everythingwas fine on video here and is great help. i had no issues with alignment of screen etc. my color and picture is much better also. inside of tv was bad. it had dust on 3 fans inside. 2 fans are in rear and 1 in front inside. dont order anything from co. called RETECHTV. they scammed me for price of a dlp chip . i turned them into my credit card co for arrest.

Janet Boyd: I want to thank you for the step-by-step video on how to replace the dlp chip. I started getting white dots about 3 months ago and getting more dots daily. I ordered the part for only $184.99 at BuyNESP.com. I replaced it last night while letting the video guide me. THANK YOU SO MUCH - it worked. It fixed the problem.

Baymond Rell: Same here man...thanks a ton really.

Brandon Bristow: Wanted to thank you for taking the time to make this video. It made replacing my DLP chip much easier.

WdnUlik2no: Thanks for the great video. I just noticed a dead pixel on my HLT6187S. I bought this TV in 2007 so I guess its about time for it to start having issues. I've already been in there to replace a fan, so it looks like I'll be going back in there to replace the DLP chip eventually. I love this TV and don't want to spend a couple of grand on a new one, plus I don't want to pay a repairman to rip me off. I'll go ahead and order the chip and when I notice more dead pixels I'll just replace it. Thanks again!! 

LAURA STALNAKER: Hi, I have a Samsung LCD rear projection ready TV Model # HL-R5087W that has great sound but no picture at all, I have hooked different thing to it DVD player, Computer, another TV, ECT... trying to get a picture, I have even done the flashlight test with the menu screen, but it does not show anything, I was told the Lamp was recently changed and the color wheel is good, it shows smiley face when its done booting up. it does not turn of by itself, when the lamp is changed and you reset the lamp hours, doesn't you TV need to have some sort of picture to be able to reset it ? and should the lamp light, when on shine up thru the square hole that sets right behind the screen , can anyone help me figure out what is wrong with this TV. Thank You Laura. 

MON KELDAD: just did my chip, I bought it 2 months ago and was not looking forward to messing with my 5 year old, $2000 tv, but without your video i would NOT of attempted it. You left out one step... which had me calling shopjimmy tech support (which is only there m-f, they left that out in their paper work and its a saturday). When you remove the heat sink you have to then pull out the PC board and turn it around to get to the Chip. once i figured that out and a total of 1.5 hrs later my tv looks great again! THANK YOU for taking the time to put this on YouTube : )))

BigDrinky: Awesome... this was very easy to follow and it saved me an expensive service call. Knocked it out in a few hours and the picture on the set is great. No more dots!

lca473: Thank you for posting this video. I got my chip on ebay, and used your video as a guide. I was expecting to run into problems, but everything went smoothly. TV works great; no more stars.

DrewFromNC: I'm replacing my DLP chip in the same model to fix the white dots. I'm down to the step where I've removed the 8 screws that secure the bracket piece above the DLP chip and I see the chip thru the opening in the middle of the board. In the video, it looks like this board pops out to permit access to the other side where the chip is. However, even with the 8 screws loose, my board appears to still be secure. How did you get the board out? Is there a step omitted from video that I'm missing? Thanks!

m cat: Bob O posted the following 6 months ago. "My picture is a bit too high. I adjusted the screen in both settings and service mode, but still too high. Any ideas what caused this? My guess would be maybe I moved the mirror slightly when cleaning or tightened the screws down to hard. Just guessing." I have the same problem after replacing my dlp chip. Any help would be greatly appreciated.

sgayres: Note the 3 plastic buttons on the shiny cover that gets removed to expose the DMD board. Do not loosen these screws. These release the board and are used to align the projected image vertically and horizontally. If these are not loosened during this procedure, your picture's alignment will not change. So leave em alone! :)

Izlude Tingel: sooooo lucky... my TV required a few hours of manually adjusting the DMD to align to the screen. pain in the neck.

Don McGreal: I just did this and it worked great. That is once I figured out that the back cover must be on for the lamp to turn on. So don't try to test it out without taking the final step of replacing the back cover. I would have saved hours if I had known.

jb1234: Thank you for the video. Your instructions made the DLP chip replacement easy, and now my picture is back to normal.

alfredo ayala: Go Easy on the Thermal Paste Billy!!!

wils2208: Have a guy that wants to charge an arm and a leg to replace this chip but after watching this video I'm pretty sure i can handle it. He mentioned something about programming the chip or something in that manner (i wasn't the one who spoke with him), but just to make sure...there is no programming necessary for replacing this part correct? and anywhere you suggest getting the part from. Only place I've found them new is eBay for about $180. Thanks

Bob O.: My picture is a bit too high. I adjusted the screen in both settings and service mode, but still too high. Any ideas what caused this? My guess would be maybe I moved the mirror slightly when cleaning or tightened the screws down to hard. Just guessing.

plasma2002: I replaced my board, and the image is great now. Only problem is that it got moved out of alignment. I just found out (via previous comments) that there are image adjustment knobs for vertical and horizontal adjustments of the image. When I was replacing my chip last night, I never noticed these knobs. Would they happen to be visible in your video? Im just trying to make it easier on myself for when I get home tonight to finish fixing it :)

Deo Wright: Hey question I have a Samsung HLT5076sx/xaa would a HLT5075sx DLP chip work?

WillFully WeirdWorld: Unfortunately Stanley, it might be a power supply problem. Having read the main thread on AVS Forums for the HLT6187, I know of several issues this TV has developed. 1) Red LED failing, 2) DLP failing (white dots), 3) Caps on power supple failing, and 4) Caps on digital board failing. One and Two are the most common and I would be willing to fix. Diagnosing and fixing 3) or 4) sound more difficult from what I've read. I've never fixed 3) or 4). Sorry. AVS forums might be of help to you.

WillFully WeirdWorld: Look below at comments by jbowen52, Sam Crook, and myself. There are knobs you can turn. jbowen52 mentions them below and I mention how to find pictures of it on the AVS forums (Google/YouTube won't let me leave links in the comments to the pictures).

WillFully WeirdWorld: The video shows me applying a few BB size spots near the center and then spreading them around the heat sink but not all the way to the edges. It will spread on its own. Since this chip is rectangular, I'd add a rice size amount centered along the longer length. A little goes a long ways. Just image a drop of glue smashed between to pieces of paper. It spreads far. Finally it's best to center it. All CPU/chips I've ever designed/worked on typically are hottest in the center. Good luck.

Veikra: My logic board kicked the bucket, but I just got a good used DLP chip for 40$, out of a hlt67 serie. Same chip, but it's not the better, black chip. For the price I cant complain. I'm looking for a replacement main board now

Richard Martin: Hi. I was impressed with your video. I have a different problem with my Samsung DLP with the LED light engine, and thought you might help me: when I see a totally black image on the screen (like when movie credits run) there's always the same pattern of greyish smudge all around the picture. What causes this? I notice it when the background is black or very dark. Could this be dust on a mirror or lens? Thanks for any suggestions.

WillFully WeirdWorld: I've seen varying prices on the DLP chip (the most expensive part). It was running ~$190 when I did it last year. Throw in the manual (I suggest in the video) and some thermal past and it was ~$210. I don't know the current asking price of the DLP chip. To me, $210 was worth it for the 61" HDTV. My very first reply to the first comment tells you the part number and where to find manuals. Good Luck!

WillFully WeirdWorld: jbowen52 is correct if the alignment issue is in the up/down or left/right direction. If you need rotation in the clockwise or counter-clockwise direction, then you need to loosen the three screws I said to "do not remove" at the 4:31 time mark. Look in the bottom right of the video for a little inset image. The service manual describes in more details; but basically you loosen them, twist/move board and have someone in front of TV telling you if you got it right or not.

David Rich: Thank you, my son (11) and I followed these instructions tonight and now have a spot free TV. Thanks!

jbowen52: Assuming you still see a picture but everything is tinted green, it is probably a dead red LED. Another chronic problem with this set, but pretty easy to fix. Parts and instructions are all online.

assisnice79: I will be attempting to replace the chip this weekend. Regarding the thermal paste, I've seen some other sites that advise you not to spread the paste out as that can induce air pockets. Do you have any thoughts on either putting a pea size or rice size application of the paste on and letting the paste spread on its own?

jbowen52: Thanks for the video. I big help. I changed the DLP chip and picture is now perfect. Just had to do a small tweak of the horizontal illumination adjuster to center the picture. Pretty easy and a big savings!

WillFully WeirdWorld: No. There is no protective film. Looking at my service manual, page 3-22, there is a focus wheel. Difficult to explain in text, probably best to spend ~$20 for service manual. One of the first post below has where I found the service manual.

WillFully WeirdWorld: The two places I found are: "servicemanuals"dot net and "service-manual"dot net I have no affiliation with any of these online companies and do not know if one is better than the other. Also, I found 3 places online for the DLP part. Put the following into a search engine and you should find it: Samsung/Mitsubishi/Toshiba 4719-001997

thegr8terrylee: My dlp tv began exhibiting dead pixels 6 months ago. I was going to replace it with a $4000 plasma. But, your vid showed how relatively simple it is to swap out the dmd chip. The dead pixels are no more and the pq is even better than before the pixel problem occured. Thank you!

WillFully WeirdWorld: I have not seen the evenly spaced vertical lines issue. My first suggestion would be to double check that all the cable are correctly seated. Maybe even pull them and re-connect. Sorry I can't be of any more help. There is a huge thread over at AVS forums. Maybe post your question there.

Deo Wright: Hey question I have a Samsung DLP HLT5076sx/xaa

jbowen52: Thanks for this video. It will be a big help. Just ordered a new DLP chip. Previously replaced a red LED as you mentioned in the video. A pretty simple job. Parts and instructions are all online.

Bob O.: Thank you for such a fast reply! I did find them earlier today and the alignment looks excellent. A little movement in the board goes a long way. Once again, great video. I would not have attempted this repair without it : )

Sam Crook: Hi, I recently replaced the chip in my Samsung HLT5075SX/XAA DLP but now the picture is not aligned correctly. How do I fix this? Please help.

spike378: does the problem come back after replacing the new dlp chip? Did they fix it?

WillFully WeirdWorld: Hard to say but my two guesses would be: 1) Focus nob needs adjustment, 2) Lenses need cleaning or weren't cleaned properly. I'll assume it's the first one; so, if you look back to the first comments below, I explain where to get a manual. Highly recommend you get it. It will explain where the focus nob is. It also has other alignment and adjustment procedures.

WillFully WeirdWorld: Hard to say without a pic. My two guesses are that you either need to clean the lenses or you may have the "halo effect". If lenses, cleaning is easy. If you happen to have one of the units produced in the first few months of release for the HLT series, there was an issue many called "halo effect". You can learn more by doing a google search with: "samsung dlp 6187 halo effect". AVS forums has lots of information on it.
