New Mitsubishi/Toshiba 4719-001997 DLP Chip 1910-6143W

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.

Replaced the DMP on my parents' 67" Samsumg DLP that the manufacturer somehow classified as failing due to normal wear and tear, even through on smaller models, the chip was replaced free of charge. The Smart Jimmy part works great. The sample YouTube video showing how to replace was helpful (although not for this specfic model). The part arrived packaged well and in short order. The price was very competitive. I would recommend this vendor for anyone suffering from the dreaded white pocks disease of a DLP. Couple of notes when doing the replacement yourself: take pictures along the way before progressing to the next step (it can save you reassembly headaches as it did for a fan orientation for me), try not to touch the "mirrored" surface of the new DMD (Latex gloves help, as does a microfiber cloth before you get under way), the main DLP board may not be completely untethered (the video does not make this clear), watch the video before you attempt this since it gets you familiar with the parts and process, have a small vacuum handy to remove dust from the heat sinks (but try not to blow dust into the light engine chamber or mirrors). The resulting picture was better than new. My parents were relieved to not have to buy a new TV or spend $$ for a repair. Even if it last a couple of years, the savings on the price of a new TV (as prices continue to drop and features continue to increase) of the same size justify it. This new part from Texas Instruments may even be better than the original.===========Update 27 MAR 2016: Still great three years later. Replaced a bulb along the way, but that's to be expected.

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.

Very fast delivery. This chip restored my Samsung HL61A750 to its former glory!I'm not going to miss the massive star field of stuck and dead pixels.Installation was relatively easy but one of the screws holding the heatsink mount was seized so I needed to use a screw extractor to remove the screw. I applied some new thermal compound on the new chip before reinstalling the heatsink.

The chip works flawlessly. Installed quickly. And was delivered 5 days before the earliest expected delivery.It's like I have a new tv.

solved my white dot problem and easy to install with video from utube

perfect fit and performance

Part fixed the problem. A little difficulty tracking the shipment... but I got it.
