I don't have much to add that isn't duplicative of the other reviews. I had one white dot on my Mits wd73733, then 5 white dots then after a couple weeks over a hundred plus black dots as well. After research I bought this one rather than shell out $5k+ for a new tv (wife won't let me get anything under 80 inches). I found instructions on how to replace it on youtube and followed them as I took out the light engine, then the dmd board, and finally the chip. I also made sure to take photos with my phone of each step because there were maybe 10 wires to disconnect and I wanted to be sure to be able to reconnect them.

Two things to watch out for. When you're taking off the dmd board to get to the chip at the back of it, watch out for the ribbon cable at the top. That sucker seems like it would be easy to crimp and then I don't even want to think about how that would get fixed. Second, the whole process took me about 7 hours because I put everything back together and had a few screws left over. I've built computers in the past and that always happens; nothing too major when you're doing it to a new computer as long as everything is reasonably secure. However, I hooked up the TV, turned it on (got the flashing yellow lights b/c I didn't put the back cover on to depress the lamp switch, first) and the picture was beautiful, but tilted on the right side.

I struggled to fix it with the menu system, even found the secret codes to enter the service menu, but finally decided I hadn't seated the dmd board properly. So I took everything apart and put it back together, this time leaving the spring screws on the heat sink a little loose so it wouldn't be so tight. This time it was worse. I played with the service menu geometry settings and got it reasonable but the screen still looked stretched to me so I knew it would bother me over time.

I took everything apart again but this time I focused on putting every single screw back where it belonged. Put it all back together and voila it worked like a charm. Kind of a pain but a beautiful picture again with no white dots!

We have a Mitsubishi WD73734 HDTV that had thousands of stars and some black dots on the screen. I read reviews for over three months, watched the videos, and monitored all of the prices trying to convince myself that a new chip would really work in our tv. I opened up our TV following what I had seen on the videos. It took about 30 minutes to disassemble. I found we had a 1910-6103W chip. I remembered reading that some folks that had circuit boards with those chips found the new chips were not compatible with their circuit boards resulting screens with black stripes. I studied some more (another four months) trying to convince myself that installing a new chip would work. When this chip finally showed on Amazon Prime at a price similar to what I had been watching on Ebay, I felt I had little to no risk, so I made the leap and purchased a new chip from Amazon Prime.
The new chip was a 1910-6143W. I had not reassembled the light engine and the TV since I took it apart four months before to see what chip was in it. I re-watched the videos to refresh my memory of how to put the light engine and the tv back together. Unfortunately I did not start the installation of the new chip until after 10 pm.I had also read that the cause of the chip failure was usually heat so I also bought some arctic silver from Amazon to put between the chip and the heat sink for the chip. We reassembled everything including the back of the tv. We plugged the tv in and the light in the front would only flash red. the TV wouldn't turn on. So we took it apart, wiped off the arctic silver and re-assembled it. No change. It was 1 am and not the time to be troubleshooting why the TV wasn't working.
Frustrated I waited a couple of days and decided to disassemble the light engine and put the original chip back in to make sure it was the new chip causing the issue. 75% of the way through the disassembly I found two cables (one of them a flex cable) that had not been re-attached to the back side of the circuit board. I re-attached them. reassembled the light engine and the tv. Plugged in power. and this time the light in the front flashed yellow. It still wouldn't power on. I rechecked the cables and found one connector to the front of the circuit board was not properly connected. After reconnecting it, I turned the tv on and the screen lit up with five black stripes and four white stripes with pepper in them. This was just like what I had read about replacing the 1910-6103W with a newer chip that wasn't compatible with the board. So I went on line and requested a refund for my new chip assuming it wasn't a valid replacement. I printed off the return labels.
I decided to dissemble the tv one more time and put the old chip in to make sure the problem was really with the new chip. When I removed the circuit board with the new chip on it, a strange thing happened..the chip fell right off the board. The chip had not been properly locked on the board. I properly placed and locked the chip on the board and reassembled the tv. We were becoming very proficient at disassembly and reassembly. We plugged the tv in; this time we had green flashing lights on the the front of the tv; we turned it on and we had a bright blue screen with absolutely no bars, black stripes or stars..it was perfect.
But being practiced we took the tv partially apart one more time to put the arctic silver on the heat sink where it makes contact with the chip. We reassembled the tv for the last time and connected up the Roku we bought at Amazon and we had the clearest, crispest 1080P picture we had ever seen with this tv..even better than with the original chip..
So if your screen doesn't light up, or you get black stripes, make sure your cables are connected, and your chip is properly locked in position.

I have a Samsung HLT6187SAX 61-Inch Slim LED Engine 1080p DLP HDTV (Old Version) that I purchased on January of 2008. This TV has been great for all these years and has lasted longer than I could have ever imagined. During these years I've only had to replace a cooling fan. However about three months ago, I noticed a white dot on the screen while watching TV. It was annoying, but bearable. However over time more white dots appeared on the screen. Depending on the picture on the screen, these dots would be either white or black. (White on a dark background, Black on a light background) Also while watching TV I could literally see pixels flickering only to see it turn into another white/black dot in a few days. I went from one dot to about 30 in a few weeks. I ended up buying this chip two months ago, but never got around to installing it until today. The chip came well packaged in a small compact cardboard box, and the chip itself was in an anti-static bag.

Watching a very helpful Youtube video I was able to get the failing DLP chip replaced with very little issue. The process was long and tedious, but there was nothing terribly difficult about the install. All I needed was a good Philips head screwdriver, arctic silver thermal paste, and quite a bit of patience. When working with an expensive piece of equipment its always best to take your time, check, double check, and triple check, before proceeding to the next step. Also I have found that taking pictures before disconnecting things and marking wires are very helpful when having to put things back together.

About an hour later I got everything back together and was finally able to see if the replacement worked. I'm happy to report that replacing the DLP Chip completely fixed the white dot issue. My picture looks flawless and seems to look as good as when I first took it out the box over six years ago.

When I first got these dots I dreaded calling a repairman knowing I would be charged hundreds of dollars, but when I saw that all I needed was this chip and how relatively simple the install was I decided to do it myself. Now I have a fixed TV and kept $300 - $600 in my pocket by not having to pay a repairman's ripoff labor fees.

If you have a white dot issue that so many are reporting as their TV's age, I am highly confident replacing the DLP chip will resolve your issue. Just make sure you verify in the product description that it will work for your TV.

Note: There are multiple sellers for this item. I got mine from ShopJimmy, they may cost a little more, but they also have a great warranty (180 days).

Note about installation on Samsung TV's
=============================================
My install was done on a Samsung HLT6187S, but this note may apply to other Samsung models as well. After you expose the board where you will install your new DLP Chip, you may see three screws behind the board. Do not turn these screws, as they adjust the Horizontal, Vertical, and sharpness of your picture. If your picture is already properly adjusted, then you do not need to even touch these screws. I have added a picture of the board to further illustrate what I am talking about.

Although I had actually build\t a 25" Heathkit color TV back in the 1970's, I had not done much with electronics in many years. But I still decided to give this a try so that I would not have to replace my 7 yr old Samsung HL67A750 television that I dearly loved until those dreaded white and black spots started appearing about 3 weeks ago. Started off with just one white dot and had gone up to 10 white ones and at least that many black ones by the time I discovered that an owner can semi-easily replace the defective part.

New DLP chip arrived a day earlier than estimated. Took about 2 hours to install into my TV including a good vacuuming and cleaning. Having done this, I think I could do it in a little over an hour if I had to do it again, but I went very slowly the first time to be extra careful. Chip itself installed easily and now all my white and black dots on the screen are GONE. Picture even seems brighter and clearer but that might just be my perception. The heat sink for the DLP chip had dried-out heat sink compound so I scraped that off with my fingernail (it was kind of rubbery and came off easily) and replaced it with new compound that I also got from Amazon.

The Samsung HL67A750 model is an LED projection TV and while looking at Youtube for videos on how to replace the DLP chip, I ran across one where the Red LED was replaced. In watching that one, the video showed how much dust was in the cooling fins for the 3 LEDs so I decided to vacuum those, too, as long as I was in the same general area of the TV. I was shocked at how much dust had built-up on the cooling fins and surprised that one or more of my LEDs had never gone bad from overheating. The cooling fins for my RED LED were totally clogged with dust and the other two were not far behind. I thought about disassembling the LED heat sinks and replacing the compound on those, too, but decided against it as I was getting anxious to see if the new DLP chip fixed my display problem.

I vacuumed the entire inside of the TV, cleaned and lubed the cooling fans, re-assembled everything and got ready for the big 'power on' test. Hit POWER on the remote and heard the TV click (as it should) and then nothing but blinking green and red lights on the front of the TV. CRAP! Took the back off of the TV and started looking around and found one connector that had pulled just a tiny bit loose when I was putting the TV back together. Re-seated the cable, powered the TV back up and PRESTO....it looks great! Worst part for me was actually removing the board that the DLP chip mounts to. Took me about 15 minutes to figure it all out and remove/replace it but now that I know how it is done, it won't take nearly so long if I have to do it again.

Now, if I can get another 3 to 5 years out of this TV, maybe the price of the newer 4K models will be a lot better by then! ;)

My Samsung HLT-6156 had developed the white and black spots caused by the DLP chip going bad. I contacted Samsung about it, but of course, my model wasn't one covered by the recall. So I did some research and found that the chip could be replaced without a tremendous amount of difficulty. I ordered the chip and it arrived a few days later, before the estimated delivery date.

I have no technical experience repairing electronics, although I have added RAM sticks and modems to my PCs in the past. I found some very useful YouTube videos made by others who have repaired their DLP televisions. They wren't the same model as mine, but they were close enough to give me a good idea as to what I should be doing.

I disassembled the back of the TV and removed the projector assembly (it is on a slide-out tray). After removing the fan, heat shield and wiring harnesses I was able to get the heat sink off and remove the board. The old chip came right off and the new one installed perfectly. I used thermal compound between the chip and the heat sink as the videos recommended, instead of the cheap tape used by the factory (possibly the reason for the original chips failing). After some dust removal I put everything back together. The TV fired right up and the picture looked great. It might even be a little better than before, although that could just be my satisfaction playing tricks on my mind,

I highly recommend this product! If you are handy in the least you should be able to fix your TV. It really only requires screwdrivers, needle-nose pliers and thermal compound. I also recommend using either note taking or a camera (or both) to document the dismantling, so you can refer back to it later if you can't remember where something went. A pair of latex gloves are also a good idea when handling the circuit board (very carefully!) and if you decide to clean the projector lens. I've gotten five good years out of my TV and am hoping for at least five more. Being user-serviceable is just one more reason why I like DLP TVs.
