Glass replacement, screen no longer working - Galaxy Note II Q&A, Help & Troubleshooting

Hi guys, cracked my note 2 glass last week and decided to replace JUST the glass myself. This included me warming up the screen with a hair dryer and replacing the glass. All went well, was VERY careful only to find out when I turn the phone on the screen is either blank OR white, and you can faintly see the boot logo. This alternates randomly when im prodding the motherboard. Does this mean there is a dodgy connection? Can I fix this, or have I completely melted the amoled when heating?
Forgot to add: Phone turns on fine, boot sound is there, capacative buttons light up. Even touch screen works (I can answer phone calls)
Thanks guys

[Q] What do I need?

Ok, so I didn't know that, that (from my other post) was "Insurance fraud". So I decided to fix the phone myself, Insurance cancelled. Now as you may already know, I stood on my phone. I am guessing that the Digitizer is the touch panel and the screen is a the botton displaying the image.. Once the damage was done, I quickly checked if the phone was alright so I pressed the "Unlock key" and had to swipe the unlock screen to see if the phone was working, so obviously the Digitizer is working as it did change to homescreen when I swiped the screen.
As I panicked I took the battery out, and turning the phone back on hoping it will work, It did not. Some green dots and lines started apearing. Then it stopped displaying, so a black screen after the vibration when I'm turning on the phone.
I also know that the phone is still working because when I plug it into my computer Windows 7 has that little bleep..
The glass screen is not cracked but, when you look at the screen at an angle you see the some scratches (or cracks) underneath on the AMOLED..
Now, my question is, do I need a new AMOLED or a new Digitizer?
thanks for your time!
edit; I've been looking at abit of nexus one Screens/Digitizer's, they seem cheaper, so would they work with a Desire?

Rainbow marks on screen

I was wondering if anyone can help me fix a problem I've got with my tp2. Basically the device turns on and I can make phone calls and use programs fine. However I can't use the touch screen at all, the hard buttons all work, but touching the screen has no effect.
When the screen is turned off I can see a rainbow pattern on it and it moves to my touch. This could be water damage but I don't remember dropping it in water. The water mark is red on the phone and battery, so it probably is water damage.
Just wondering if anyone knows an easy fix for this. Thanks for reading
Just had exactly the same thing happen this week. At first if I turned it off and firmly pressed my thumbs up the screen (as if I was pushing the rainbow marks to the edge of the screen) I could get it to respond for a while. Then it started to get larger spots and now I can't get it to respond no matter what I do...
If the touch screen is not functional, then you'll likely need to replace the digitizer. I would suggest purchasing the LCD/digitizer combos, as they are easier to install for first timers.

[Q] N7105 LTE - failed screen repair, won't power on

Hi,
I have attempted a glass only screen repair on my Note II which in hindsight was probably a mistake. Initially, I though things were going bad as I cracked and heated shards of glass away from the disassembled phone. Fully expecting to need to buy a new LCD/digitizer I eventually removed all the glass. Before cleaning the screen, I plugged it all back together and to my amazement it worked. Everything turned on and the digitizer worked so I turned it off and went about cleaning it up.
I then realized I could remove the backing that the glass was on, the bit with the black bezel. I don't know what this was or if I should have removed it or not. I cleaned what I think was the digitizer and LCD, put the new glass on and assembled the phone and this is where I'm stuck.
I try and power it on and all I get is one little red LED flash when I press the power button. When I press the power occasionally the screen flickers briefly as if it wants to turn on. I can't reset (10 seconds power) or hard reset (volume up + home + power). The phone is at full charge, it takes charge (my power supply "whistles") and the battery is at 4.1V.
Does anyone know what this symptom is or what I may have broken? I'm thinking I could have ruined the screen somehow, perhaps I shouldn't have pulled that last piece of plastic off or perhaps I have killed the motherboard but I don't see how..? Thanks for any assistance!
So I fixed the phone. Solution posted in case anyone else runs into this issue.
When I was removing the last layer on the screen or cleaning the goo off, I must have broken the screen. The red LED flash when I was turning the phone on is normal, it is just that the screen was not working. I got a new screen assembly and replaced the whole thing.
I've replaced about a dozen phone screens for myself, friends and family and I would strongly recommend replacing the whole screen assembly on a Note 2 instead of a glass only replacement.
I am a tech that does glass only replacements every day on s3 n2 and s4 and I can tell you that the black layer you removed was the digitizer and front half of the lcd that's were you messed up

[Q] Glass is fine, black screen, notifications lights still work

Hey guys,
I have an S3 that was dropped and now the screen remains black but the notification light still turns on and it still rings/vibrates when it gets a call or message. I was told it was a digitizer issue and hence ordered a replacement but now I'm reading that it may be the LCD? The glass portion is completely fine, not a crack or any sign of breakage to be found it's just that the screen remains black.

If the glass on the outside of it is undamaged, then it likely is just the digitizer. Try putting on the replacement digitizer and see where that gets you.

[Q] G3 virtually unharmed after dropping, but screen won't turn on

So while walking downstairs to my basement, I tried to put my phone back into my pocket and it slipped and dropped on the hard floor. It dropped about 4 ft and it had a hard plastic case around it (one of the Korean model cases with the small section exposed though). The glass screen protector I had on it cracked, but the actual screen is fine. I tried turning the phone back on, but only the notification light comes on and it keeps blinking green and blue.
EDIT: So I guess the LCD is broken cause the digitizer is completely intact and there's no indication that the phone was even dropped. Usually its the other way around.....

Exactly the same thing happened to me. No visible damage, but screen wont come on. LED is blinking blue and green.
Do you have any new updates regarding your phone problem?

The only new thing that I discovered was that the backlight is probably broken. I can see a very faint image of the LG boot logo and the carrier logo when the phone boots up, but it just hangs there and the LED keeps blinking till the battery runs out/is taken out so I don't know what else is up.

No cracks at all. The only crack I had was on my tempered glass screen protector. I thought it was the actual screen, but I took it off and the screen was unscathed.

Take it back to and tell them that the phone just stopped working. I'm sure they will fix it under warranty.
