Need urgent help. Screen randomly went fuzzy/dead. Same cyanogenmod rom for months! - Sprint HTC EVO 4G LTE

I was in class today and my phone vibrated a few times notifying me of text messages. I checked the phone when I got outside and was greeted by this screen

Not my phone, but the same problem!
I've been running the same CM 10 rom for months now. I can't remember if it was a stable or RC but it was good enough that I didn't feel the need to mess with my phone for perhaps the last 5 or 6 months. It's been a while.
Details:
The phone still vibrates and receives messages. I know this because I'm confirming with google voice online that messages are coming in when its vibrating. I can turn the screen on and off, but I'm just greeted by this screen. I can force the phone to reboot by holding the power button, but even the starting animations won't show. It turns on immediately to this. During the start-up animation, it usually has a point where the screen brightens and then dims and even this occurs. The buttons and everything are all doing what they need to do. I can unlock the screen and everything as I can feel the feedback. The volume rocker works and reacts properly. Everything is working except the screen.
Any ideas?
I'd like to apologize if this is a common problem and the solution is posted somewhere as I have not frequented these boards recently and am currently at work so I can't spend much time searching.

Yeah, see my post about the confetti. It went confetti very soon after it went contrast. I run stock CPU speed with stock voltage.
Ironic that yours happens just as mine did. I'm using the phone now. I have the screen turned on to never go to sleep now so that I don't have to try and wake it up. Then I may get that screen and to prevent that? Turn it off, turn it on, turn off, turned on and eventually I'll get the lock screen.
I run meanbean rom with the 1.19 hboot, s-on. I'm going to return it to stock then take it back to sprint. Provided I can keep the phone functional long enough to do this.
This will be my second phone to do this. First 1 did it last September.

It's a shame. I've had this since launch and haven't had a single problem with it. Unfortunately, no matter how many times I turn the screen on and off, I can't get it to the lock screen.
Edit: I have a feeling this isn't going to be an easy fix. I'm gonna switch to my brothers old Evo 3D as soon as I get home

http://forum.xda-developers.com/showthread.php?p=38160970 is my original post (first)
I would like to add the screen freezes when the battery gets to a full charge. Unplug it and it recovers almost instantly. Interesting I'd say.

Yeah, I went through your post. I can see that no one really had any idea for you either which was kinda disheartening. I'll have to play around with it when I get home tonight, but I'll be forced to switch to an older phone as I won't have enough time to fix this on my own right now

Sprint exchanged the first one because the grfx chip went bad according to them. My concern is that it was not that long ago and now I have the same issue. How old is your phone?

My concern is that they won't exchange it unless I can get it back to stock, but I'm assuming there's no way for them to know considering they can't access anything on the screen?
I've had the phone since June. Never had a problem with it

I think the screen might show via the hdmi feature but I'm not going to force the issue. You should be able to answer incoming call via bluetooth adaptor. I can also listen to Pandora via bluetooth through my head unit in my truck. Also make phone calls through my head unit to but I'm not going go to the car in the phone calls unless I'm in it.
If your proficient with voice commands via bluetooth or Google Voice you maybe able to get some functionality of the phone for a little bit more time. I would like to see if other folks have this issue also.

I found a link to this program which allows you to access your phones screen that I think may be helpful! I'm going to use this to get what I need off the phone, get it back to stock, and return it to the store tomorrow. I'll update this post later tonight when I get home

The only time this happened to me is when my voltages were too low. I would boot into recovery and reflash your ROM or the voltage increase script in thick lizards dev host folder.
If you can get to recovery which shouldn't be a problemyou can fix this easily.

So I'm back to stock using racun's soff procedure. I still has pixy dust issues. Will look into the thicklizzard angle tomorrow.

Have you tried getting into the bootloader?

I tried using android screencast, but I don't think it's possible to get it running without interacting with the phone. I can't even connect the phone to my computer and use it as a storage device because I don't remember exactly where the buttons are. At this point, I'm considering flashing cm10 onto another device so that I can see where everything is and replicate the location of the screen presses on my LTE to try the voltage trick or reflashing the rom.
I'm very likely going to take it in as is and hope they don't have any way to see if its rooted or not and just give me a replacement.

Yeah, but it still gives me the same screen.
Edit: I can't even switch to my Evo 3D because it says I need to switch my plan. This is just another sprint headache considering my plan is fine for the LTE it should be fine for the 3D. I'm gonna wake up at 4am to talk to chat since they're not currently open

Zori, is your evo S Off? Then you can flash individual kernels I think. If it is, then take a CLOSE look at unlimited.io/jewel.htm because most of that procedure is remote terminal. If you do it via ubantu, I'm thinking you can push the proper package onto the phone and update it that way.
The hardest part will be getting to recovery from the hboot screen and BAM!

The bootloader screen:
At the very least it can get you to the point of getting to stock I think. My phone seams to have recovered a bit at stock. I briefly see the confetti when I wake it. I can imagine that it would be an under volt condition while powering on. You can do it mate the force is strong.

vipermod looks relevant to our issue. I will need to do some reading while the bosses are not looking.

Answer to confetti screen issue
My phone did this exact thing on Saturday. I took it in to the Sprint store, and the tech there (the only one I've ever run in to who really knows his stuff, Phil in Westminster), explained that there is a cable between the battery and screen that is "kinked" and loses contact. If you squeeze the phone really hard just above the back button the screen will come back on for a bit. They did agree to send me a new phone (I am rooted, and running a custom ROM, they did not care). I've been able to get enough functionality out of it to get by for about two days, but as of last night the screen only stays on the "confetti", and won't come back at all.
Anyway, hope that helps a bit!

Yup.. mine started doing the same thing couple of days back..
I instinctively started pressing the screen and it came back on.. must be the same prob like ur sprint guy said..
I'm thinking of going to sprint store but I don't have their insurance or total equipment protection plan.. so, any clue on if they will replace? Do u guys have the TEP?
Edit: Let me add that I have noticed that the screen fuzziness happens whenever i put the phone in my pocket... have started carrying it around in my hand now!!

I didn't think I had insurance, and they were going to charge me $50 for a replacement. After they looked at my account it turned out I did have insurance on this line, so no charge.
Unfortunately, I got the replacement last night, and sound doesn't work on this one! Getting yet another replacement on Friday.
