[Q] Back light only comes on after replacing LCD and Digitizer

Hello, and I appreciate everyone who has taken a look at this post.
I recently replaced my LCD and Digitizer. A couple of months ago I dropped my phone into the bilge(bottom of a boat) filled with oil. When this happened the digitizer had a crack in the corner and the LCD got flooded with oil, not to mention the phone. I took of the back cover and let the oil drain out. I didn't open up the housing or anything. I soaked up as much oil as possible. Still though, half of the screen was a few shades darker and difficult to read text messages and playing games were out of the question. Everything else was fine, the OS didn't slow down and I saw no signs of rust anywhere.
During the holidays, I got the digitizer and LCD. So I followed the video on youtube from this website on how to take apart the Xperia Play. I replaced the LCD and I used the same adhesive strip over again with the digitizer. Now when I turn on my phone, it vibrates, but the back light comes on periodically for about 2-3 seconds and then turns of. And then a few minutes later the back light will turn on and turn off again. i get no picture from the LCD. I have turned it off and on a few times. Same thing. I have also tried turning it on while holding the power button and random combinations of the other buttons. I plugged it into my pc and when the back light goes off, my computer detects a device but shortly after losses it.
I have read through other threads to see for similar stories. The only thing i can think of is maybe, I damaged the strip of the LCD or i fried my mother board. I just would like to know if it is another problem or if anyone has some good solutions for this.
If anyone can help me, it would be greatly appreciated. I love this phone and this n00b needs some help. Lol.

If it was just oil you dropped it in then the electronics will probably be fine as it is non conductive so the problem probably lies somewhere else. I do many phone repairs, mainly to iPhones, HTC's etc, but I have never done an XP so not too sure on specifics but what you describe would probably be ribbon cable related, either not a perfect connection or slightly damaged. It only takes a slight nick on the ribbon to render it useless. I replaced a digitizer on an HTC sensation once and the phone did exactly the same as what you describe. I took the new one off and put the old cracked one back on and the phone was normal again.
Dunno how much that helps but hope it's of some use

[URGENT]Screen!

I've broken my screen, to be accurate not me but some dude, he paid for the new screen. Ofcourse, he picked the most ****ty store he could to fix it to pay less money for it, it was horrible. Light from the side of the phone was leaking, the buttons didn't light up well, the front camera lense was missing and most importantly the screen itself wasn't like before. First of all, it fell off from the phone all the time ( with just the two connectors connected ), it was horrible pale and etc.
Being the social akward I am, I was silent about it, and got used to the screen after I glued it.
Anywho, yesterday without any warning or anything screen stopped working. Sound is playing, digitizer is prolly working, screen? nah. Black screen. I opened it up few times before as the LCD connector disconnected, it was okay. Now the connector was inside still, connected and I opened it and tried to tighten it up, thought it was loose or something. Nope, still no screen.
Now I come to you, xda, with the need of help.
Where can I buy a REAL. LCD2, like stock screen?
And if its possible, how can I identify if the screen I got earlier IS lcd2 original screen? ( the seller said it was, obviously it wasn't )
Thanks! ( Really hope for fast answer )

[Q] One X Warranty Farce.

I got my One X in June last year, in Jan it developed a screen ripple on the top left of the screen. I could hear the device clicking if there was any pressure applied and a ripple went across the screen.
I sent it off to HTC for repair and they accepted it as a Warranty Repair. I got the phone back a week or so later with the fault not having been fixed but they had left dust behind the glass and the camera lens and a lump of black debris covering the flash.
I got straight back onto them to find out what was going on, they told me that the LCD panel had been replaced and I should return it again for the problems to be fixed.
I sent the device back a second time and got it back 48hrs later. I was amazed by the quick turn around and opened the box to find that the dust remained behind the glass and the camera lens. The screen ripple was still present also. I phoned them again now to find what had been done this time and they said that the main board had been replaced. (I am not sure what was wrong with the main board). They told me that they needed to repair the device again to get it right which I refused, After talking to a supervisor (which in itself is no easy job.. They don't call back when they say they will) They agreed to replace the device.
I boxed the phone back up and waited patiently for my new HOX to come in the post. When it arrived I thought that my problems would be sorted and I could return to using the phone, but... This device had screen ripple down both sides of the screen (much worse that the previous one) and had light leakage below the glass when the capacitive buttons were lit up.
I got back in touch with them and they begrudgingly agreed to replace the device again.
This time it took them a week to get the device back to me and I have just opened it to find that this one has worse screen ripple again down both sides (No light leakage though).
The ripple that I am talking about is if you lightly run a thumb nail down the black area of the glass on either side of the screen, the screen changes colours as you move up and down.
My colleague in the office has a HOX also and there is no sign of ripple on his even with a lot of pressure.
I am completely fed up with dealing with their customer services and cannot be bothered to go through all of this again.
Has anyone got any suggestions? Should I escalate this to their head office?

posts like yours make me double think before sending my one out again for repairs...i have got a yellow spot on the top right hand side of my phone...cover it in a black wallpaper you do not even notice it.
stick a white wallpaper though it is there...was thinking about sending it out but for a little spot i am thinking of sticking with it and save up some money and buy a new phone in a few months...
if i was you though escalate the matter till you get yourself a brand spanking new one and one that actually is flawless..
hamdir did not rest till he had the perfect one and he went through like 12 handsets if i am not mistaken..so if i was you send it back and keep nagging on them

[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

No Display after dropping phone

Hi,
Unfortunately for me i dropped my phone and cracked my tempered glass in several places. gladly the screen underneath was perfectly fine after drop however, it has developed a fault as the screen won't turn on at all. I tried turning it off and restarting and although i can hear the boot up logo sound i see no picture at all. i can receive calls but cannot answer due to screen not displaying.
The screen had four main pressure cracks.... one is top left, one on the ear speaker, one bottom middle and one bottom left of phone. hopefully you can see it in picture.
Can you give advice on what to try or do to resolve this? will i need a new screen or disassemble to see what the issue is?
I've only had the phone for 2/3 months at most
Thanks in advance

looks like i will answer my own question....
i bought a replacement lcd & digitiser, one complete unit and swapped the necessary components over to new screen. all is working and good. not sure if the screen is repairable but there are other parts inside this screen worth selling on. it still has a non cracked immaculate screen along with the charging port and other stuff inside old screen.
at a cost of £70, i consider this an expensive fix
Thanks for the input kakawak
cheers
