DLP Chip Numbers

Hi all,
I have an NEC NP200 DLP projector, whose DLP chip is pretty much dead (white dots all over the screen, hard to see image anymore). I got it taken partially taken apart, and safely got the old DLP chip out of the lens assembly. I looked up the model number on the chip (1076-6319W), but I couldn't find a new one at a reasonable price with that same model number. I'm usually OK with used parts, but used parts for electronics like this make me nervous, especially when its harder to tell when a used chip will go kaput. My question is this: does the model number matter as long as the DLP chip is the right size? And if it doesn't matter, how would one tell the size based on internet pictures and descriptions?
I included a picture of the dead chip from my projector below.
Thanks,
-sebrow01

fairly sure the numbers matter.. might want to google DLP cross reference and see if there is anything out there that may answer your question.

I doubt TI makes those anymore. Very old.

You can grab a comparable model for 20 bucks on CL. Not sure I’d pay much for a replacement chip.

Probably need to call them for advice. They have an online store for authorized dealers. Your projector is 10 years old and 4:3 old resolution. My guess is you can pick up a 1080HD projector for about $300 these days that will run circles around your projector, and it will probably cost that much for a TI chip replacement.

If you are going to fix it go for a used one, lots on ebay for under $100 https://www.ebay.com/sch/i.html?_fro...6319W&_sacat=0
But putting that towards a new or used higher end HD projector would be a better use of a $100

I have to agree with @Verge2 on this one... Watch your spending and the amount of time you are willing to put in.

This is a 10 year old, bottom of the line (at the time) XGA projector. It carries very little value and really beyond the 'fun of trying' aspect, doesn't deserve much else.

I wouldn't even spend the $20 for a replacement chip via eBay. It just isn't up to the task of acceptable home theater quality. But, if you do want to get it working, that's about the most you should spend.

Sorry...but wasn't the "white dot" issue a dmd board problem, and not necessarily the actual chip that failed?
Agree that it really isn't worth it...but if he decides to mess around with a repair...I'd hate to see him up the wrong tree.

Thanks for all your thoughts and comments everyone! While I do like the idea of fixing stuff vs buying new stuff, I totally agree that at this point I should just cut my losses on a 10 year old projector like that that is pretty inferior to modern ones. That being said, it works well enough I might be able to get a little more use out of it before all the pixels go white, so is there anywhere I can buy just a replacement thermal pad since I scraped the old one off? I’m assuming thermal compound for computer CPUs would just make a mess and not actually do much here, right?
