How To Repair Dead Pixels On Ti 84 Plus Black

Today I noticed that one of the pixels on my screen near the acme left is either dead or stuck. It's not solid color, in fact I tin can't seem to effigy out what colour it's trying to display (it changes when I motility the screen effectually) so I'm hoping it'southward merely a stuck pixel. Please correct me if I'one thousand incorrect.

I looked online and a lot of solutions involve physically touching the screen which I can't do anymore. I saw some software fixes as well though, one displays colored static on the screen which has about a 50% run a risk of fixing the pixel. I was wondering if this could also piece of work on the CE? I made a quick program that fills the screen with random colors that change really chop-chop to simulate the software, but I have no idea if it's really going to work the same way.

I'd similar to know if anyone knows anything about these displays that could set up the pixel.

Here are some images, information technology's really obvious in the checkerboard ones.

Dang that sucks, yeah it could be either dead or stuck.

Also not to be silly, only could information technology besides be something stuck to the screen similar grit etc?

I would try some software solutions before looking at more desperate measures similar manual massage etc.

It... worked?
I wasn't expecting to make this mail service only that color irresolute program actually stock-still it! I left it running for an hr and when I came back information technology was working again.

If anyone is wondering the lawmaking I used, here'south the ICE source lawmaking:

Code:

[i]PIXEL
det(0
Echo getKey(1)
randInt(1,255)->C
det(5,C
Cease
det(1

If you lot don't want to compile it, here'south the compiled code. Press the downwardly arrow to leave and make certain you have the C libraries!

Dainty work man!

What's the physics behind this? How could a unmarried pixel go "stuck", and how can a plan that turns it on/off brand it "unstuck"?

/me can't assist optimizing...

I dunno the detailed physics, but hither's the article I referred from that helped me set it, it also explains a bit into what's going on and why each fix can set up the pixel.

I got an email back from TI-cares basically stating that my calculator is screwed and I need to pay $81 to supplant it.
I haven't told them it's fixed nevertheless. I've sent them back an electronic mail asking where I can purchase a replacement display, I dubiety they'll tell me annihilation useful though. I also told them I took the calculator apart, I wonder how they'll react to that.

I once had an LCD monitor that developed a stuck pixel (it always stayed a cyan color; most visible against a dark background. I tried those various �static� apps and stuff, but cypher seemed to aid, then I simply lived with it for a while. Then several months later, I discovered it had finally stock-still itself at some point! Crazy.

That's about my only feel with bad pixels upwards to this point. Except an old camcorder I came across recently which has a stuck CCD pixel! Bright blue dot in the heart of the frame, even in total darkness. Pretty annoying.

I estimate I'thousand a bit tardily, only yous might be able to get physical admission to the LCD from behind.

You can order replacement LCDs from the aforementioned identify TI gets them---direct from the original manufacturer (can you read and write Chinese?). Given that the TI-84 Plus CE already has a screen protector on it, such Shenzhen shenanigans are probably more profitable for the B&Westward models. I'chiliad sure yous could get a nice petty side hustle going if you could lay out the $1000 or and then you'd demand to become a full production run of LCDs---you'd only have to ready a few dozen calculators to make back the initial investment.
