S6 No video, touch screen and phone works besides a black screen.... - Galaxy S6 Q&A, Help & Troubleshooting

I did a search but, didn't find my EXACT problem.
I have a Verizon Samsung Galaxy S6, Everything seems to work but, there is a black screen. You can hear the touch screen working and all the buttons seem to respond to touch (hearing things happen). The phone is in perfect shape and looks brand new so It was not dropped or anything.
Is there a "software" way to recover this phone, or should I just sell it off for parts ?
Thanks in advance !

Help! Verizon Xperia Play screen replace

Hi Folks,
Sad news, I dropped my Play the other day and cracked the glass cover on the screen. but still the touch screen works fine. So I decided to buy glass replacement on Amazon and fix it myself. After juggling with the new screen whole night, only more problems occurred.
First is that the new screen won't boot into Android. The phone starts up and displays fine but it stayed at "Sony Ericsson" screen for a long long time without moving onto "Android" screen. I thought it was because Verizon, as a control freak, has a hardware lock on the glass (the glass does have electrical connection to the mb.) So when I swapped back the old screen, the phone worked fine.
So the first problem is that OEM glass don't seem to work on Verizon phone. Is that possible? or is there a way to bypass that?
Then the big issue occurred after trying put the new screen on for the second time. It displays only white noise like screen and seemed to stay that way.
Now I am like OMFG. The whole phone just died on me. Does anyone know what caused this messed up screen? what is the best way to fix it?
Thanks a million!

Problem after touchscreen replacement (original one)

Please help me with this touch screen problem:
In my HTC sensation 4G touchscreen has been replaced (together with display) and as a result I've noticed that device no longer registers fast swipes. No lag or other problems, just when you move finger fast - touchscreen fails to register it. In multitouch tests circle disappears during fast movements and in games like fruit ninja there is no line after the finger. Guys who helped me tried several digitizers they had in stock and all of them had this same problem.
My original digitizer and these ones are probably different models because mine was T-mobile and these have HTC written in the middle.
So I wanted to ask did somebody stumble upon this issue and is there a solution?
Or is it possible that all new ones they've tried are bad?

i have similar issue. my screen doesn't register any touch on the left half, unless i touch the right half a few times first...:/ my digitizer got changed as well. but after that all is fine...only after i turn off the screen, then on again.....it's a little annoying, but not making my device useless at least.
as for to what's the cause, possibly each phone needs a special digitzer...as for the solution, i tried many, nothing worked...
I read of someone with a similar problem, they took screen apart again and found the wire was slightly pinched, they said they carefully put wires back in place and paid extra Attention to the wires and problem was solved. Now, I personally have not tried it but I did read this fix. Maybe it might help, worth a try? Hope this helps!
Sent from my HTC Sensation 4G
I'm on the same boat. Dropped it and cracked the screen. So I bought a replacement screen and replaced it myself. Its the one with just the HTC in the middle. (I'm T-mobile) Well now, like yours, it sucks at registering touch accurately. I have to press solidly on the screen to swipe screens or to open apps. Texting sucks because i have to press on each letter good or else it picks the wrong letter. I've searched for a solution as many have had this issue but seems like they just returned it for a new one. I cant since i replaced the screen and voided my warranty. I have taken it apart twice and carefully reassembled it making sure everything is good and snug and in the right place.....Still no love....Sucks! If anyone can help, it would be much appreciated as i have hit a dead end with this issue. Thanks.

this is quite different problem. Sensitivity of my display is OK unless you move fast. In your case it seems to be the problem of this exact screen. Try downloading SGS Touchscreen Booster from Play Store and play with settings.

Question regarding galaxy S3 repair.

Hello,
I've recently been given a Galaxy S3 phone. The phone has preciously been dropped in from what i understand it some water. Now the thing is. The phone's touchscreen is broken as in the touch doesn't work. the LCD however works so you can clearly see the image. Now for the rest the phone works. When you charge it up and start it. It functions properly loads up the operating system even the alarms work well i can't really press anything since the touch is fried but everything else looks good. So now i am about to order a touch screen + lcd replacement for it, including a backplate since it's kind of bruised. My question is what is your opinion of this.
The phone has previous been taken to a store where they demanded 300 euro to fix it under the condition that the touch screen was broken. So it has been researched from what i assume were professionals.
Before you ask i have plenty of knowledge with repairing fixing delicate computer equipment i have no knowledge of how to change a screen however plenty of online videos about it and it doesn't really look that difficult. Now my question is do you think the phone would work if i am to change the LCD + Touch.

Touch Calibration

Ok so ive replaced the screen on my mums N5, with one i got here.
(its not letting me post the link to where i bought the screen, i'm too new, but this is the description "US White Google Nexus 5 LG D820 D821 LCD Touch Digitizer Screen Assembly + Frame", i got it on ebay)
The installation went fine i think, i may have damaged the camera, but i biggest problem is the touch screen. It was ok after a reboot and it was not charging. But now it is totally off now. Like and inch or 2 off making it unusable. Ive been trying to find a way to calibrate the touch screen but i have not been successful. I was hopping that someone had an idea of how to fix this. The phone seems to work in all other ways, but its hard to test at the moment.
Thanks T

[Q]Problems after screen replacment

Hello. My screen cracked last week so i decided to buy new digitizer with frame and replace it on my own. I bought it for 35$. Replacmet went smoth, but screen didnt seem to work. Phone is booting and its loading android, I'm able to spot it couse there is a sound when I press volume up or down or try to make screenshot, but all those sound are delayed about 2s. Screen just display only one color at the time, its changing for another one for every ~10s. I was wondering if I bought crappy screen or i messed up something with wires?
Does the old screen display an image? If it does , reinstall the old screen to see if the images are properly displayed. If they are properly displayed, looks like the replacement screen is not good.
Sadly, old screen doesnt work. I was excepting that new screen may be the case, but i'm worried about lag after adjusting a volume. It may may be coused by screen?
Sounds to me like you have received a defective screen. Contact the seller to get a replacement.
