Or figure out what you own in an attempt to find out or narrow down from the many posts/ info and contribute to further discourse, apparently.
If looking for support, you've got to help others here help you, which does require a little effort. If that's not for you, probably contacting the reseller should be a first call. You might have tried the reseller, but how one can know without your commentary.

Tried the seller, now since 6 months, so far no help. Have not found any one that had the same problem, but thanks for your reply anyhow

When you power off and back on, does the splash screen show up reversed? This would help indicate whether the issue is software problem vs a hardware problem. Once the unit is booted up and everything showing up backwards, do the touch screen elements respond to touch in their new reversed positions? If the on screen elements in their new positions respond to touch, that would indicate that the digitizer essentially is reversed in addition to the LCD underneath. Quite odd, indeed.
I would suggest to connect a USB mouse to the unit and use that to navigate your way to the factory reset menu and give that a try.

Thanks for your reply. Yes when staring up the splash screen is reversed as well. To use the Icons you have to touch the screen on the opposite side of where the icon is displayed. I will try the suggestion with the mouse to navigate and report back,
Thanks again

[Q] HTC Touch Pro screen does not respond to touch

First of all Hello and thank you for having a great forum. I have learned a lot from the posts that I have read. Ok, like I said my touch screen lost its touch. It started acting up last week and got to the point where it would not accept touch input. I tried a hard reset, but I still have the same problem.
I am beginning wonder if any of you sages and guru's may have come across something like this in the past. I tried flashing the device but it is difficult since I can not touch the screen to ok the program load.
So, do I have a hardware or software problem? Also, are there ways to select a soft key other than touch? Thanks for reading and if you got any ideas let me know.

I would say its a hardware failure, especially since you flashed your phone and your screen still wont register any touch. But I would wait for a second opinion before I take it in to be serviced.
Thanks, but I was not able to flash only reset it using the alternative method described on Verizon's website. I am trying to flash the phone with a new ROM, but the phone prompts me to click 'yes' or 'no' on the screen to install new software. Of course, that is a no go. I tried to flash from the security unlocked screen but the flash program will not run. I am almost out of options.
You woudn't be using a case on the phone by any chance, would you? I have noticed some cases extend onto the screen too far, causing it to be touched, and then it wont recognize any other screen touches.
I went through the same thing a year ago, and I found some posts from people with the same problem.
It is caused by gunk getting in groove around screen.
take a business card or similar thickness paper and drag through groove around screen.
If that does`nt work get a piece of duct tape and apply to screen and gently pull off at steep angle.
It will lift screen back up and unstick it.
Oh my God... only now I understand what could happened to my Raphael:-O

[Q] Screen issue, can only see pixels

Hi,
I'm not sure if there already is a thread about this problem, so sorry if there is
When I grabbed my Nexus 5 out my pocket, the screen didn´t work. It only shows pixels. I´ve tried to reset it to factory settings using a hard reset but that doesn´t work. It still only shows the pixels. I can´t send it back to LG for repair because I´ve changed the kernel and I can´t get a connection with my pc. Does anybody have any idea how to fix it?
Thanks in advance!
What do you mean by "can only see pixels" ?? Blurry lines?? Distortion?? If so, there's a possibility that the flex cable might have gone bad.. In any case, you need to send it in for repairs.

Yes I can only see blurry lines in different colours. But is it possible to repair it by replacing the screen + touch module?

May be, May be not. No one can know the extent of the damage without opening up the device.
You need professional help. So, it's either Google (if you've bought from play) or LG. There's nothing you can do here as the screen is completely useless. Just send it in and hope for the best.
If you want to backup your data, you could boot up the phone (if you can) and use adb to backup if you've enabled usb debugging. But that's about it..
Good luck!

Nexus 5 showing only pixels
Hi
Even I am facing the same issue. My nexus 5 is only 4 months old and from the past few days, display is not working consistently. It only shows pixels all over the screen and there is no image at all. Also, there is no physical damage to the phone at all. Although It just fell once recently on its back from a chairs height but it already had a strong spigen slim armor case that provides pretty good protection so i dont think that fall could have caused any internal damage.
A few days after this and after i upgraded to 5.1, I first started to see the screen hanging and then suddenly when i tried to restart, it started showing pixels all over the screen. A few times when i press power button multiple times, then sometimes (say 1 out of 20 times or even less) ,home screen appears but even then it does not work. I am very frustrated with the problem and not sure what could be the issue. Could you please let me know what could be the problem. I have shown it to some repair shops but it looks like they are just looking to grab money and they simply tell me that they can replace display.
So i thought its better to post it here in xda to get feedback on this. Please can you let me know what could be problem, is it hardware or software issue and how it could be resolved. Please help me urgently as I am not able to use the phone.
Thanks.

Messed-Up Display

Hello XDA,
My Nexus 5 running CM12 5.0.2 nightly will not respond to the touches anymore infact when I press the power button to activate the display it acts as if someone is touching it randomly messing all the apps that are running and opening and closing many other things.
Furthermore it displays weird and burned lines throughout the screen. It was not dropped, no water went inside the device or anything. If it helps I did install the OTA updates that CM gives us.
I have also attached pictures so you may get a better understanding of my problem.
Thanks in advance.

Hmm I see. Well since a month HAS passed, its definetly not the rom thats causing the problem, i don't know if anything regarding the software could even be causing the problem. Its 100% hardware and by that i mean the screen, you should change it, the touch and also the display are messed up.

I hate to be the bringer of bad news - but your screen is toast. Fortunately you can replace the touch and display components all at once.
http://www.amazon.com/Skiliwah-Digitizer-Assembly-Google-nexus5/dp/B00HN0U168
Here is what you need to perform the repairs - and here are the procedures for disassembly.
https://www.ifixit.com/Teardown/Disassembling+Nexus+5+Display+Teardown+-+liquid+damage/32410
Trust me, it's not that difficult. Unfortunately, it's a bit pricey ($60 for the screen and digitizer), nevertheless much cheaper than a new device or sending your device in for repairs.
Rma
Problem Solved
The screen isn't toast, neither is the digitizer. I have 2 of these phones. The parts which cause problems like this are the main board and the ribbon with the USB connector on it, which also attaches the screen & digitizer to the main board. One was showing lines exactly like this, & also no touch. I put a replacement main board in. Works great now. The other, wouldn't even turn on. I put the main board from the first phone in the second one, it still wouldn't turn on. I replaced the ribbon cable, it turns on and perfectly replicates the issue from the first phone. So now, I have one fully functioning LG Nexus 5, and another which turns on with the same problem as yours. This is good, I started out with 2 of them that were useless to me. So, it appears that your display and touch issues are caused solely by a bad main board. A replacement main board costs somewhere around $75. After swapping stuff around, I have 2 bad main boards, 1 bad USB ribbon & 1 working phone of 2. Not bad, not bad at all.

MTCD screen is displayed mirrored

I am facing a very strange bug since yesterday on my MTCD KGL.
The screen is mirrored, but the touch panel is not. So everything looks like seeing it through a mirror, but the touch panel is still in the correct orientation.
So e.g. a "Cancel" button is displayed as "lecnaC" and is on the right, but I still have to touch on the left to push it.
Even the boot logo and the recovery are mirrored.
WTF???
Do you have an idea what is going on with my unit?
Damn, this thing is not really usable anymore.
Just another "cheap" China product for the bin.
I should have better lit some cigars with the three 100€s...
So out of nothing it mirrord en before not?
Then it's software problem so fixable... flash MCU, flash image.
Everything comes form China nowadays, besides you know the risk if you want to buy cheap unit...

Yeah, did that already. Didn't help. That's why I'm like wtf...
Meanwhile I found out, that when I'm playing with the hardware power button, pressing it until reboot, that's flashing three times, then randomly pressing it short or long, I can change the mirroring from "flip over short side" to "flip over long side". But that's even worse. Did not manage to get it to correct orientation.
I know sometimes you win, but this time I seem to lose heavily.
Thanks pal.
This happened to mine and i couldn't understand what happened...tried every setting and a factory reset with no luck. And then one day it fixed itself. HOWEVER i did read on another forum a display cable comes loose inside and causes this. Just need to open it up and re secure the display cable...
This happened to my mtcb joying unit. I asked the manufacturer and they said it's like the graphics chip.

Normally these use a long ribbon cable to connect the internal boards together and then another to connect the display board to the LCD.
On my last unit the LCD cable was pinched by the metal case, causing random display issues.
Taking it apart and readjusting the cable so it was not pinched solved the problems.
Most manufacturers put the ribbon right at the bottom of the case, so any pressure on the bottom of the LCD can cause issues.

SOD (sleep of death)

I noticed, that my 1+1 always works ok on stock roms (cm11,cm13 from this forum) and when i set up Android Oreo or Halogen (7.1.2 unoff) or even Flyme 6, my screen don't want to wake up from time to time, buttons vibrate, sound works, all works except screen. Even though, i noticed one way to wake it up, just repeat the touches some times, double tap to panel (i don't see it), and again, to block the screen... it wake up always, or reboot sometimes, but this is not a variant to use at real situations. somtimes headphones help, sometimes usb cable, but no 100% solution.
may be someone know how to solve this problem? i saw a lot of messages here about SOD, and no solution. just something about a modem or flash stock, but this is a software trouble, may be it is firmware.zip or just one .bin file inside (power management). may be this error can be solved?
I really want to go to Oreo and today i tried to do it, but when I suddenly understood that it doesn't work again (after stock) i decided to go back, no way to use it. may be i should take some files from stock?

that's the way, but not for me. i've just changed my display, i just can check old one, it is not broken, just a dead zone on the touchscreen. but it means that the revision is incorrect, it is something like a driver, i think. i already had the same situation with a old tablet, it didn't wake up anytime after boot, it was discussed at 4pda, so people found, that only one of the 3 revisions works ok at last firmware, i had 2 type of display and could to swith and check it. but it wasn't so good with colors, so i stayed at stock. it seems that situation is the same now.

Why do yoy think so? Stock fw can realize all functions for that display, why custom can't do it at the hardware level? no reason to think so.
Just only one idea - is a revision. Now i can try my old display. And if i'd manage to change touchscreen, that can be a solution. But i don't.

Aliexpress?
Yes. But at first everything was ok. And when i installed oreo it stops some times and Sod started. I tried to use 7.1.2, it SOD's anyway. Then the stock was the solution. I'm already relaxed, and decided that it is software error, but after a few days it started again.
I've accepted this display, but with your help it's not so late to open a dispute. I think it will be ok.

Get ready with a lot of proofs tho'!
to me it happens, I do not know if it is the same as described, but unlocking the screen works everything but not touch, lock, unlock, and it works, what is it due?

See previous page,I've already explained what is the cause of the issue.
I just finished replacing my screen, been waiting for my broken antenna cable and volume button flex to arrive. Everything works except the damn SOD i never had with my old screen. Tried turning off the proximity sensor check and still a no go. The screen turns on fine initially and trying to wake it instantly works all the time, but if I leave it off for any longer than 5 sec probably it won't respond to anything - power button, volume button, double tap and plugging in the usb cable connected to a power source.
Does this sound more like a governor issue? The rom installed is lineageOS (just updated to 10-30 release). Looking up my purchase log to open a dispute...
tested it again, repeated lock/unlocks puts it into the SOD state, doesn't even take 2 sec to do it...
oh wow, it does this even in the twrp recovery. I have wiped cache and dalvik cache just for the hell of it but doubt that was the real cause...

i've got the first SOD in twrp mode. it doesn't matter, but at first - no troubles were with that. and now it works so so at home. and if i use it outdoor it becomes very often, but at home it seems that it works ok, just only seems, because if i want - i can do some manipulations (use camera, lock/unlock it etc) and the SOD appears again. but custom os executes SOD more frequently. i think it can be real overvoltage, like people says.
there are many posts here and everyone advices not effective solutions (flash stock, modem, fw ...) at first it helped me, but now i know there is no way, i can just try but ...
long time ago i owned an old tablet iconbit matrix - it has just the similar issue. it boots, but if you go to a sleep mode - it didn't wake up every time. it lights works ok inside, but no image. i had two displays and if i used one in a custom rom it worked ok, but not another one. stock rom works ok with every display. the solution was a display driver, like at windows OS.
cause of developers bugs, it was a little different (not stock-based) and some revisions of display works ok, others aren't.
so, i think it can be fixed, but the solution for me - change a display like the first reply says. Ali seller read this topic and posted me this in a few days after i started this topic:
Your dispute has been processed and the money will back to you in 7~10 working days.
so could you give us a positive feedback, please?
Best regards.
so, i'll order another one, no trouble, i hope this will help me to enjoy my oneplus.

They always ask for positive feedback in exchange for refund/replacement.Bastards,aren't they? @evronetwork
For the sake of other people that'll read your feedback and make their decisions upon it,don't do it! Just complain this bribery to aliexpress staff ffs!
well I wish I bought from aliepxress... I bought mine from ebay to pinch some pennies, and because I was waiting on other replacement parts (which were only needed due to damage occurred during a screen replacement op) to ge here I am way over the protection period. aw shiiiiit, I guess you live and learn
gotta tell you though, the screen is a bit wacky in other ways too. the capacitive buttons do light up but not completely (kinda dark in the corners) and the colors look a bit off. hopefully the seller would honor the refund/return request...
EDIT: whoa... kinda hard to believe, but I messed around with battery profile just for the hell of it and by some pure luck discovered that the "performance" profile (second one from the far right) works just fine and wakes the screen every time. The "balanced" profile and everything below that gives me an insta-death. go figure!
EDIT2: guess I spoke too soon. it sure as hell looked like fixed, but it came back after a while. maybe it is just more sporadic than I thought...
No solution yet? I think, that it can be some trouble with lights (this wire with 3 contacts), because touch starts, but no image. may be the signal comes to the matrix, but it is not enough energy to enable this diods. what can we do? im going to change the back side of the screen.
ow, no way, don't even try, it has combined technology. i disasabled the whole wire, no chance there...

What happened to getting a new display?
I use this one, because it works ok, but only at home. As a home tablet. At the street it fails every time.
I can reboot it if it doesn't wake up. But it wakes up often, so i don't want to order new one now. I want to check my mainboard to be sure, that it is dispaly problem
a bit late, but thought I should update on the situation... all working fine after a (yet another) LCD replacement. Much better color balance to boot, points to QC problems at the supplier's end. If I ever have to do this again, I am definitely going to inspect the new LCD as soon as I receive I receive it.
