Black Screen HTC One (M8) - One (M8) Q&A, Help & Troubleshooting

I'm having trouble with my HTC One M8.
It wouldn't read the sim card, so I replaced the screen as this was also broken so thought I might as well kill two birds. However after finishing the repair now the screen is completely black, it will boot as per usual and touch will respond as it should. Just nothing appears :'( . Any advice as to what I should try? I've taken the screen back off and cleaned all the connections etc, so I've got no idea what the issue could be.
Thank you

HTC Touch Diamond Screen not responding

Hi All,
My diamond screen suddenly stopped responding. The screen calibration is also not working. I tried a hard reset and after that, it stopped at the screen 'Tap the screen to setup your windows phone'. I am not even able to do that. Any help is appreciable. Thanks in advance.

Try re-flashing a rom, or maybe your touch screen (digitizer) needs replacing, if you do this yourself i would recommend buying the digitizer and lcd together as one, it will make a whole lot easier trust me lol. The lcd screen is easy to break.
Had this problem, too, but since I couldn't get back to stock SPL at that time I put my Diamond into a shelf for about 2 days.
When I then tried to get back to stock SPL the screen suddenly responded again.
So, try to take off the battery for a long time (more than a day) and hope it recovers.
Didn't have the problem again.
Change the Touch Screen

I had a similar problem solved with changing the touch screen since the phone was under warranty I have to revert to the stock SPL and stock ROM before I gave it for service. If your phone is not under warranty you can buy the touch screen from ebay.com with a manual and all required instruments for replacing the same.
This happened to me because I was talking to someone over an hour in a humid place which caused sweat to get into the phone through the speakers.

Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!

Putting the phone in the fridge makes screen work!
I know this is an old thread but why does putting the phone in the fridge for a few minutes make the touch screen work? Even if I put it out of a moving car and it cools down, then it works for a bit.
Anyone know why this is and how I can fix the phone permanently?

[Q] Screen Replacement Issue. Advice needed please

Hi there,
I have my friends HTC 8S which needed a screen replacement. Which I volunteered to fix as I have previously successfully replaced the screen on my old HTC One X. However, after following all the steps that I researched, an issue arose where I would part assemble the phone (all cables on the motherboard connected, battery connected) to check if the screen would work and there was nothing, I tried a soft reset to see if that would work, which it didn't. I assembled the phone fully to see if it was maybe a loose connection so if I button it all up tight then the connection will be made but that failed also, I even tried the old screen again, that wouldn't work either! So a faulty screen & digitiser is out of the question.
I was very careful when replacing the screen & to my knowledge I have broken nothing. The phone does receive calls, the buttons do work including the light sensors for the home screen etc.
So I'm pretty stuck & feeling bad as my friend is without a phone. So any help or advice will be welcome
Thanks

[Q] HTC Desire 816 touchscreen not working

I dropped my HTC Desire 816 twice today accidentally and the screen smashed.
The phone works fine but the touchscreen won't work. I have tried restarting the phone multiple times and everything.
Is there anything I can do to make the screen work (like maybe something has moved on the inside) or is the crack the issue and therefore I need to get it replaced? I'm fine having a smashed screen as long as the actual phone works.
Thanks!

I assume it's issue with digitizer, Try replace digitizer and your device should good to go. And use bumper or avoid drop!
Should be like this: http://www.ebay.com/itm/Touch-Scree...e_Replacement_Parts_Tools&hash=item3ce450fa46
Find one for yourself and get replace it. Or head over to htc service center to get things done.

HTC One M8 Touch screen problem

Hello folks,
I have had my HTC M8 Dual sim for over a year now and had no problem with it whatsoever. On January I think I had an official Android upgrade after that top screen started malfunctioning. It was like I am pressing with finger on top of screen all the time. And then, the same area stopped responding to touches at all. Screenshots with screen test is attached.
Soft and hard reset did not help.
Any idea what could be wrong and how I can fix it?
I have same problem with my m7 tried doing everything however didn't suceed. I'f someone could help even I would be happy
I had the same happen on a One V, I had to replace the screen to fix it. The digitizer was damaged by something. The phone did experience a few drops, and was in my pocket when I fell.
The connection inside may have come loose as well. It is something that can only be fixed by opening it up at this point.
