Touchscreen not working - Galaxy S II Q&A, Help & Troubleshooting

Hello all,
First of all I hope I am writing in the correct section... Otherwise please let me know.
Secondly: Something really strange is happening to my Galaxy S2.
Last year, the glass broke on the street and I changed it manually by buying one from eBay and following video instrctions. This year the touch and AMOLED part of the screen cracked (I don't even know how). This time I decided to buy a Galaxy S4, as I didn't want to "invest" anymore on the 2-year old smartphone, but I kept it. Later this year I decided to fix the S2 one again, and so I ordered a replacement screen (which costed a whopping $105!!!) and changed it. To my surprise, although I checked all the motherboard connections more than twice, the phone turns on, the Welcome Screen (configuration for first time usage screen) appears, but... The screen is unresponsive and I also can't change the volume nor turn the screen off by pressing the lock/power button.
If someone knows something about this problem or how to fix it, I would appreciate a comment with information regarding it to be able to understand what is happening.
Thanks in advance!
B.S.: I don't know if this information has anything to do with the problem, but the first screen I bought wasn't original, as it didn't have the Samsung logo on the ribbon cable, while the new one is original and the Samsung logo appears on the ribbon connector. I wonder: Is this a factory failure?

[Q] Screen not working at all - white with horizontal lines across it

Hi Guys,
I bought a Galaxy S2 in late August and have been using it since then. It is also using Siyah Kernel with Galnet MIUI Rom.
This morning I pulled the phone out of my pocket and the screen was completely white, with horizontal lines across it. I have attached a picture to described what I am saying (sorry for the quality, it is behind a white table but the light from the screen makes it so the camera only picks up the screen).
What's interesting is that everything else is working. If someone calls me, the ringer will go off, and I can guess the gesture to accept the call and have a conversation, so it just seems to be the screen.
I have tried a few things already, but any time the screen seems to have power its just white. You never see the initial Samsung Galaxy boot screen, and I tried going into recovery mode and the download mode and both the times I can't do anything.
Is there a way to flash without having any visual control, and even if there is, do you guys think its worth a shot? I bought this phone from someone online and not sure if I can still get the Samsung international warranty.
Any help is very much appreciated.

Holy crap. That's a hardware defect. Go to download mode, flash original firmware, use jig, send back to Samsung. But it seems that it has been dropped in the top right corner, didn't it?

I dropped it the night before on carpet, but everything was fine. I used it the whole night, and in fact I even used it the morning of. Not sure what happened but I pulled out my phone because it was noticeably warm, probably from the screen being on.
I bought this phone online, and it originally belonged to a Samsung Asia employee who no longer works there. I checked the box for any warranty information, and the page containing warranty information seems to have the international warranty code page ripped out.
Anyone have any idea of the cost of getting samsung to fix this? I tried calling Samsung Canada and they gave me a number for the company that deals with their phones, but I haven't had any luck reaching them. I also tried looking for screens online but they are so expensive.

if its not a hardware defect then install via odin some other firmware...
if that not going to help then return it to samsung and claim your warranty - dont mention that you droped it on the carpet thou... ;]]
It has to be a hardware defect if even the boot logo doesn't show right? (the initial galaxy s2 screen)

[Q] screen replacement

I hard bricked my note a month ago so I decided to buy one off of Craigslist that was working and all I had to do was replace the screen. I had an AT&T phone so I made sure I purchased the same model. I took the broken screen out of the phone and replaced it. No broken cables everthing secure but when I turn on the phone the screen is crazydark! I checked the cables and I dont see anything wrong. Help please what went awry?!
Any pictures? How dark?
Ill post them n a sec, very dark can barely see the bottom apps on screen. I know the screen worked because it was from my other galaxy note.
I took phone apart and put back together I did notice that when I hit the back button the very top of the screen is visible. Now however I cant see anything on the screen.

the screen is turned up to the max!
Where you able to solve it ? My Galaxy Note N7000 looks like it has quite a similar problem and I'm quite sure, that it's not caused by defect hardware.
In the case that your still looking after a solution, i have posted my problem here.

[Q] Xperia MINI PRO sk17 , screen remains black, although working

HI everyone My Xperia Mini Pro worked just fine, then one day the screen remained black after unlocking it... it still worked, i could feel the touch and vibrations, i could basicly do everything just that i wasn't able to see it. After some shaking, pressing, sliding the keyboard out, it came back to its normal state, but would go black again if i pressed it hard and hold...Now the screen is always black. I hadn't really dropped it, it wasn't exposed to high temperatures, it just happened......i took it to some service centers and they have changed the flex cable a few times but didn't work..they assumed it was a hardware issue.....My warranty's long out.....WHAT SHOULD I DO???...Is there a chance that a screen change might help it and what would it cost me? please help

My friend broke his XMP screen bro, and in the service center they charged it too heavy such that he can buy an another device
try flashing stock ics just to check if it is software problem else you have to bear expenses if you cant miss such a good device

[Q] Help with Warranty

Two days ago I bought the Galaxy s4 black from verizon wireless website. Today someone dropped my phone. The screen is cracked and wont turn on. When I press the button the screen turns green for a split second and turns off. Is the limited warranty covering this? I really need this phone and will be in alot of trouble if this is not free/very cheap to fix.

This is not a warranty issue. The warranty will not cover someone dropping your phone. I'm sorry to hear you are in this position.
Your only option is to get the glass, screen / digitizer replaced and hope that is all that is broken. As it is, it won't be cheap to fix but cheaper than buying a new phone at full price.
Or, you could just buy a used one on eBay or Craigs List, just be careful.

Screen issues after replacement

Hi at all,
my uncle's Mi A3 had cracked screen, so he told me to replace it with a brand new. I replaced it the first time, and after some time the screen became useless because of bad lines (green, blue, yellow) all over the screen that didn't let you do anything. So I gave back the replacement screen to the seller that sent me another one of it. Tested it, mounted it and now after a week the same problem. Now the phone has been shutted down because of low charge, this morning i tried to charge it and now it works well as usual. What the f*** is happening? bad screen replacements? Did I do something wrong each time I replaced it?
Thanks a lot to all who answer.
seller has good display??
checkup ur mainboard too.
