Black screen on boot - stock firmware - MTCD Android Head Units Q&A

Hi, hope there isnt a thread already coz I couldnt find one.
For last few days my unit is starting up with black screen. The lcd backlight is on but no image, just black.
The 1st time I tapped and prodded and after a few mins driving it flickered back into life by itself.
Now it's doing it daily after car has sat overnight. I thought it might be the cold weather, but its still low 20's ish.
I havent done anything to it other than change a few progs. Genuine stock firmware etc. Its a mtcd px3 erising unit.
The audio works fine (if radio left on when switched off) but when the screen starts to work, it gradually fades into life while there are horizontal white flickering lines that are gradually replaced by normal image coming into view. It takes approx 7 mins from start. Isnt effected by roads, bumps etc and once on works perfectly with no flicker at all. Def' a weird one. Any one have any similar experience ?

[Q] Display colors too dark?

I got in a car accident yesterday and my phone was in the cup holder, we were going pretty fast and slammed into someone and the airbags deployed and his car was ****ed. I got my phone from the car about 20 minutes later before they towed the car. the phone was fine but later today the colors became really dark. When i reboot my phone the colors go back to normal for a second at the boot logo but one sec later the boot logo is dark again. could this be from damage to the phone from the accident? the phone looks in good condition. and it happened a couple of hours after the accident. i can also now see pixels in all the texts and images i have. Any Straight lines are now dotted lines on the screen. What is going on?

[Q] Myphone a919 duo/Micromax a110 Screen Issue

this happened like 4 months ago... i was just watching movie and suddenly the screen drops quality then starts flickering, appearing multiple dots of colors. So i immediately turn my phone OFF - removed the battery then after 3 minutes I put back then turn it ON...after that incident my phone now has LOW QUALITY of screen. All text/letters are almost look like pixelized(not really clear), white/red/blue/green shadows appears when background is black or even if the background has bright colors a white shadows appears below and above the bright color, when playing games for long time(2-3 hrs) the screen will starts flickering again(I noticed the back of the phone below the back camera is getting hot).
Before all this happened, for almost 1 week i was playing games while my phone is charging. But during the time it started i was not charging my phone. It appeared 5 hrs after i charged my phone...
My phone was NEVER DROPPED, NEVER GOT WET.
I included some Screen shots...
Is there any other way to fix this problem and restore the screen quality of my phone without buying NEW LCD? If there is, please tell me how or just give me the link or application needed to fix this issue...

[Q] touch response gone - but works when i freeze the phone to 24degC

I have a strange issue on my nexus 5. Little long post - so please read at leisure.
Got my nexus 5 in November, the october batch. No issues till now and on 4.4.2.
Little background:
I am in Bangalore, India, where the noon temp probably hits 38C (100F) in May month.
I went on bike in tuesday at noon for couple of hours with nexus 5 in my pocket. That might have heated up the screen and insides.
I have antutu widget that shows the temperature, memory and also the cleanmaster.
I came back home, didnt touch the phone for a while. Later on went out in my car by 4PM. I observed that the touch response is gone. The screen is working and displayed time accurately, the notifications are coming, even getting calls. However, i cannot take the call since i cannot slide to answer.
By evening, i went to my office and observed it worked for a bit and then stops working all of sudden.
The temp shows 32C (for the processor i think) and it jams the screen.
I went into a cold conference room and stayed there for a bit where it was 23C room. The indicator showed 28C and touch works.
If the temp shows 30 it jams again.
I went to the local LG service center(Marathalli, Bangalore, India) last night and showed it to them. It seems they don't have stock of the screen to replace and asked me to call back. Today i checked its not yet come. Tomorrow might be possibility they would get and replace the touch screen.
However, if I continue with this technique of freezing the phone to cold temp and observe it works, slides, opens all tools. Once it is little heated up, it jams.
Now i observe white horizontal patches coming across the screen . If i turn off the screen and turn it on, its gone but comes back again.
Very strange indeed for me. Any insight on what is happening? I expect the LG nexus to be tested for high outdoor temperatures like in tropical India (40C - 110F).
It might have broken something internally like a small circuit being burnt and its probably working only in low temperatures. Still it is appalling.
Any thoughts and ideas?

We can assume that the digitizer is losing connection as a wire expands and contracts. LG should replace the screen for you free of charge, unless they come to the conclusion that it was damaged by the user.

[Completed] Strange hardware issue

Dear XDA,
My phone served me well for the last two years, but a few days ago it started acting strange. The screen is the problem. So the first time it happened i was playing a game, and suddenly the screen froze and the colors started changing, lines started appearing, and then kept inverting colors, all in a matter of 4-5 seconds, and then it went back to normal. After a few more times this happened I came to a conclusion. It had nothing to do with the GPU because if i shake, hit, or make sudden movements on the phone then it comes back to normal. After a few days i had to gently tap it against a wall to return everything to normal. During the whole messed up screen thing the touch still works. I can still unlock and make calls and everything if i remember where to tap correctly, but the screen visually messes up. Now the bigger problem is that those taps have to be stronger, at one point the touch didnt work but the screen showed regular colors and animations, and then went back to normal with occasional visual problems again. In the end i planned to use it as an mp3 because the screen is fully black. The screen is black but lit up, so when i touch it it gets dimmer, touch with one more finger gets even more dim, and when i release then it lights up again, black. I couldn't find help anywh ere else on xda or google, so i need your help. Is there anything i can do from my end? Is it some dying resistors which i can solder, or if it is the screen cable, or what is it? What can i do to get the most out of it? (flashlight, mp3, or is it absolutely useless)? Some information on what it is would be useful.
The phone is a 5'2 inch Alps Tudou91 D1 1gb ram cortex-A7 1.2ghz
PS: I will add the pictures and a video to this comment once i copy it from my friends phone
Thank you.
Hi, thank you for using XDA Assist. Some times phones just wear out. It could be the digitizer going bad, a loose flex connector, or a number of other things which can't be diagnosed here. I would suggest you take it to a local cell repair center to have it checked out.

Neuxs 5 screen problems

Ok so my Nexus 5 has a real problem with the screen. Started some time after Lollipop, haven't used it since
When I turn it on it only shows "static" screen. It can stay like that or after some seconds purple and white(the white from the Google logo?) but mostly purple going down the screen. When it reaches the bottom I starts at top again(I can see cause the white spot are changing locations).
I have no way to fix it so I just hold the power button till it turns off
Some times (if I'm lucky) the screen is normal (maybe some of this youtu.be/drZc4ZPcuvo) but it works for some time(minutes) until it either turns off the screen(timeout) by itself or it just "jumps" around till the screen becomes black.
I have tried replacing the USB flex cable without luck. I also shattered the glass 1 year ago(havent used the phone for 6 months).
After replacing the USB flex cable yesterday I got it working with just minor issuses. And update to 5.1 etc. (running stock)
But I have however not done a factory reset as I believe this won't fix the phone.
Any good Ideas on how to fix it? Replace the screen (by my self) cost 1/3 to 1/2 of what I paid for it originally. And if its the motherboard/GPU its "dead"?
Better off replacing the device entirely
