My evo is about to go through the wall

Short Version: Phone worked, Sat for a month, doesnt get past cyanogen screen goes into protect mode.
Okay i bought an evo that had the screen replaced on it. The guy obviously didnt know what he was doing. So I dropped it one day and the digizer ripped off.( the flex cable ripped, The digitizer wasnt stuck down) So a month later, i finally got around to buying a brand new housing for the entire thing. I took the mobo out and put it in the new housing. It worked for about 5 minutes then gets stuck in a boot loop. I had it happen once, before i got the new housing, It took me 5 minutes to get it to work again. The phone would shut off randomly sometimes.
It worked fine before the screen broke off no major problems would shut itself off every 2 or 3 days. The board has sat in a bag on my table for a month and now it wont work.
Now i cant even get the phone to stay on at all. The cyanogen screen shows up it loads and then shuts right off (i have recovery) I have tried different kernels,roms, and radios. The phone goes into protect mode now. Can I hit with a heat gun and reflow the cpu like a ps3 or xbox? Is there anyway i can remove all hardware failure protection?

You have any insurance? Depending on how your morals are you could try to make a warranty claim on it (although after todays announcement I might feel bad considering theyre trying to help us out). Otherwise I would try flashing an RUU and if that doesnt work take whatever means necessary, although Im not sure why your mobo would be damaged after a month, have you tried cleaning it and blowing on it to get all the dust out?

My recommendation is to make sure you stretch first, then when you do throw the phone through the wall, that you make sure it's a wall that's going to be easy to repair.
Reading your post it looks like you bought a phone that was practically guaranteed to have problems.
You bought the phone equivalent of a lemon, so expect the same amount of effort into keeping this thing alive as if you were to buy a car lemon.

short of running an ruu or smashing it and saying you 20lb sledge fell from 20 feet and landed on it lol

I've never looked into something that says "protect mode" for an EVO.
However, most electronic can do this if the thing is going to over-volt. If you think about car amplifiers, they do the same thing and go into protection mode which means that capacitor or something much more is bad.
I agree with the other guy and that you threw yourself into a bad deal from the start so it's as if you're going to be fixing something that's already inherited potential issues.
Have you considered that the replacement screen may be the culprit? Aside from the potential drop damage that could have broken something on the logic board, the another possibility is that the hardware you just installed could be defective and causing the EVO to do this protect mode.
In any event, the best solution would now be to work with a company to get a diagnosis of the problem. If you get a diagnosis only, you can buy your own parts and do it yourself if you're like a McGyver type-a-guy.
Find a credible cell phone repair shop and just get an diagnosis first.

[Q] How to fix my screen?

My screen died last night. The phone works as I can hear all the sounds and my bottom buttons still light up, etc but I have a black screen.
I called a local repair shop and they stated it wasn’t worth repairing and that they’d be guessing what parts need replacement. Based on the symptoms above is this true? Can anyone tell me if they know what part I would need to buy to try the repair myself? Is it worth trying to fix myself?

There are two parts, the screen itself and the digitizer. The digitizer is the actual glass you touch, if that's not cracked, then you are good with that. The screen is the actual lcd under the glass.
Both can be found on ebay for 20-50 bucks, and there are tutorials here and on youtube to show you how to take it apart and fix it. FYI, there are two types of lcd's, one with a small ribbon and one with a wider one. The only way to know if to take your phone apart so you order the right one.

Seems like I can get both parts from Amazon Prime for less than $50 total which makes this worth a try. Can you suggest a good tool kit for this project?
Thanks!

Not worth repairing? I'ts cheap as hell to repair your issue.

You can also buy the replacement parts from that website as well. However, you might browse ebay first to see if you can get the parts for cheaper.
Edit: If the guys at the repair shop can't have any kind of educated idea as to what would be the problem with your screen going out then i would suggest not letting them anywhere near any of your computers either.
1. If screen turns on when the phone initially starts and then stops working when Android attempts to load then you've obviously got a software issue.
2. If screen doesn't work at all during the phone's initial startup process then you've obviously got a hardware problem.
3. A quick Google search shows the parts involved in replacing a screen and countless videos on how to do it. Takes only a few minutes to get a complete understanding of how it's done (It's not all that dissimilar from replacing a laptop screen). And it probably take 30-45 minutes, taking it slow since it would be a new process for the tech, to actually do the replacement.
4. Any semi-decent tech should be able to diagnose your problem within 5 minutes of looking at the phone and then have your phone back to you an hour and a half after receiving the parts.

#2 describes my phone except the screen came back on today so it is intermittent or possibly in the process of dying. The phone is rooted but running stock so I don't think software is the issue.

Second Pixel C with same issue - backlight stops working.

I am on my second Pixel C where the backlight has stopped working after a month. The screen still works, if I shine a light at it just right I can see the contents (especially when they are white), but the backlight just doesn't come on. The previous one did this on and off for about a week while waiting for the replacement, meaning it would occasionally come back on and work for a little while. But, right before the replacement arrived, it went off and never came back on. My replacement did it for the first time today (it is one month old now), I connected to my laptop when I got home and issued an "adb reboot", and it appears to be working again. I have requested a refund from Google, but they said they couldn't authorize it, so I have filed a dispute with my credit card company in order to get my money back.
Overall, I like the device. I have had to work around a few of its shortcomings, but everything was satisfactory. I just can't keep replacing something every month.
Has anyone else experienced this? I mean, I know how to search and have found similar reports, this exact issue. Where the screen still comes on and is visible under the right lighting conditions, but the backlight is just non-functional. If so, what was the recourse you took to solve it? I have tried not putting it in my case (thinking that was the problem), rebooting (which occasionally has worked, but not always), factory resets (real tough without being able to see), plugging it in when malfunctioning, leaving adaptive brightness disabled, cursing at it and throwing my hands up in the air in frustration, etc. Nothing reliably works, and now I am afraid to let it go to sleep seeing how it came back after the reboot today.
Thanks for reading this...

My Pixel C started doing this last week. Wasn't so bad at first, but it's slowly gotten worse and starting last night the backlight will go hours without turning on. I've tried charging it, hooking it up to my computer, and just finished a factory reset and nothing has worked. Just like you if I shine a light at the right angle I can see things, but that's not exactly fun to do. Bought it at the end of March, so it almost made it 4 months.
One thing I should add, and this is probably a coincidence, is it started happening right after I downloaded the July updates. I only mention this in case someone else has had a similar experience.

My second one had gotten even worse, the screen sometimes comes on now, but the right half is either just fuzz or completely distorted, and the touch screen is non functioning.
I have ordered a Samsung galaxy tab s2, and will get my money back either from Google (doubtful), or my credit card company. Hope Samsung updates it at least to N.
I'm so torn, when it worked the pixel was awesome, I love the screen, closest any has come to the ratio of my camera. But two in a row only lasting a month each, and it's hard to consider a third, or fourth...
Sorry yours is glitching out on you, hope you get a satisfactory resolution.

I have the same problem. Exactly like you describe above. Since my Pixel C is one month out of warranty there is nothing I can do except warn others not to buy this product,
Oliver Browne.

Same here for me. First one started with screen issues as described above, lucky for me i was 3 days before the end of waranty, second one lasted 93 days... 3 days out of waranty for a replacement device! Thanks Google for a cheap device...

I face the same issue, and was able to turn on the backlight by adjusting its brightness using the touch screen. Try shining a torch onto it while locating the brightness setting. This temporary fix works for me every time, and hope it helps someone.

Trying the torch was very useful! I now know for a 100% that the backlight doesn't work. I used the torch to see what I was actually doing on the screen, and erased all data & cleaned the cache.
Unfortunately the backlight stayed off, so I assume it's a hardware issue.
I've sent an email to Google support, hopefully they can get this one fixed or replaced.

did you manage to fix your issue ?

Same issue here, and no not resolved.
The only thing I can do to work around it is keep tapping the power button every second. Eventually you get lucky and the backlight will turn on. (Rebooting doesn't seem to be needed.)

Hi all,
I bought this tablet as a gift for my little brother. He encountered the very same issue 2 or 3 weeks ago, and it became worse today, as now backlight won't turn on anymore, even after a reboot and a factory reset.
It must be a hardware issue...
I will try to contact their after sales service, as the tablet isn't even 6 months old.

HI, my first Pixel c met this issues after 20 months... first it was only sometimes and backlight came back after some pushes on the power button... but it get worst and worst: 2 days without backlight and at the end half screen fuzzy issues. I order a replacement product with my warranty (2 years in Europe)... and now my second Pixel meets the same issue... with a no responding screen issue too... it's awful and my warranty is over yet... nothing can fix this...! something seems to be bad quality in this device....

I'm on my 2nd pixel c and final. Google support said that because they had replaced it under warranty the warranty only applies to the original purchase date not the replacement which seemed BS to me because I was shipped a refurb tablet
Never the less using adb/ fast boot I was able to get the device into bootloader and blindly reload the entire operating system. It was only until I performed a wipe within TWRP that the screen started working again. Interesting and now off it is working for the past hour or so. Currently applying latest updates but not holding my breath. Unfortunately it looks like Google is killing off the tablets and I don't know if any of their Engineers have actually tried to use a Chromebook in place of a tablet but it just doesn't translate well. If I cannot get this device working reliably I may buy another refurb to get a few more years out of it. The pixelbook is way too heavy for Couchsurfing

The screen comes and goes with no particular interaction. I'm really bummed because I had gotten so used to this device. I buy another but I'm afraid it's going to happen again. I don't see any tablets that are upgrades either. The Android tablet days are over. Pixelbook is not intuitive. Although it runs Android apps it does so very poorly with in Chrome OS and it's very bulky. I'm a try my luck with another refurb off eBay. Have not been able to find anyone that can repair it

HTC 10 Half of Display Not Working After Screen Replacement

The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.

Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance

Exactly the same issue this guy has

I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory

I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?

I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.

Touch not working after screen replacement

Hi guys
I wanted to ressurect my old moto g5 (cedric xt1676) which i was not using for a longer time. Screen was cracked but touch worked just fine. I bought screen replacement assembly and connected it. Screen (picture) is working fine but touch is not working at all. Is there any way to solve this problem? What i found untill now is that after some update motorola/lenovo disabled support for 3rd party screens - one i bought is stated to be "original" but i doubt it.
I did a factory reset before removing old screen, after connecting new one, start menu was in russian (i can't read bukvas so its a guess ), after another reset it is back to english but touch is still not working. There is a padlock symbol in top left corner of the screen.
I just wanted to fix the old phone to give it to the family member but now i spent so much time on this issue that i want to fix it very badly.
Hope that someone can and want to help me.

At the end of the day it's all down to if the correct parts were used and if it was fixed correctly. Nothing we can really help with here.

It's Russian ransomware screen
Seriously always use OEM parts.
Make sure all connectors are intact; remove and inspect contacts. Make sure you didn't miss a ground or data connection; sometimes they are just contact points between assemblies. Using the wrong length screw may cause a missing contact pathway. Assemble exactly the way it was.
The mobo may have been damaged when the display was broken. High G impacts can internally damage chipsets and crack solder joints. Flexing a multilayered mobo can break internal traces.

Sorry to hear that. Anyway - i have nothing to loose so i would try with olderversion of android - is it possible to instal without working touch in the phone?
