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

Best money spent, fixed the white dots on the screen, took 20 minutes to repair. I have the Mitsubishi WD-73835 73' TV, the YouTube video was excellent and very informative. I work with electronics so I knew most of the things I needed to do. The shop Jimmy's guys have there act together and really are trying to help people to fix there own TV cheaply. I only found one problem. In the video the guy says to save the heat sync pad to reuse it.by twisting the heat sync then pulling it off carefully, this is wrong. My TV is 7 years old, the first dot appeared and two days later another and after that at least one a day till I ordered the new chip. When I placed the order, before I received the new chip, I took the TV apart to make sure it was a easy as the video said and clean it, and it was. The heat sync pad crumbled when I removed it, so I used Artic Silver heat sync compound to put the original chip back. Artic Silver can be purchased at any PC store or through Amazon, its used to mount the CPU to the heat sync on any PC and much more effective than that pad because CPU's get much hotter than the DLP chip's. Anyway, after cleaning all the fans of dust and crud, and turning the TV back on, the dots were still there, but never got another dot again for a week and a half the TV operated perfectly and no more dots, The heat was causing the problem of the dots and you should not reuse the old heat sync pad, buy fresh on Amazon or a PC store. I repair PC's and a rule of thumb is never reuse, wipe it off and put fresh on. When I installed the new chip I did the same again and its been perfect ever since. Will update if anything changes.

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.

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.

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

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.

Bought Chip to replace my original chip in my Samsung DLP 62" tv, which was failing and showing white dots on the projector screen. Installed new chip in November 2017, then in June 2018, white dots start appearing on screen again. By end of July 2018, so many white dots are on the tv screen, that it was un-watchable. The new installed chip has the same fault as the original, except it only lasted 9 months before failing!

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

perfect fit and performance
