Help - Daughter broke LCD on her G2 :-(
So we ordered a new one from Repairsuniverse.com and meticulously followed their instructions. Everything appeared to go very well and the screen worked afterwards. There was however a faint strange blue spot in the center of the screen. 2 days later the brightness stop working. Now the screen is very dim and can be only read the dark room. When I contacted the supplier they attempted to blame it on the motherboard.
Any ideas? My daughter wants her phone back :'(
It sounds like the backlight for the screen went bad. It may be a loose connection to the motherboard though. I would try to disassemble the phone again and make sure the ribbon cable from the screen to the board is tight. If it is and there is still a problem, it is probably the screen.
Thanks... Appreciate any and all input.
If the ribbon is loose, I would think that the screen would work intermittently or not at all though. Instead it works consistently, only dimmly and won't brighten or respond to brightness control
I would tend to think so as well, but I have seen some strange things for cables being just slightly loose. If you feel comfortable disassembling and reassembling the device I would suggest it just to rule out a loose cable.
You may just have to fight with the LCD supplier to get a replacement though.
Thanks again for the input. I definitely feel comfortable enough to take it back apart. We already had to do a complete breakdown once before in order to replace the LCD. Now the LCD works but it's stuck on the lowest setting.

I have hardware version 0003, the display works fine just the top glass got cracked, can someone point me in the right direction for a new digitizer assembly? I found one on amazon new for 24$ but have no idea if it will work for my phone.0002 vs 0003 I read have different ribbon cables.
Sent from my EVO.
When this happened to me, I couldn't tell that the LCD had also cracked. I bought the digitizer only, and when I took apart the phone, I realized that I didn't have the parts I needed to fix it.
I can tell you that the correct P/N for the Novatel screen is 2V6A, but I am not sure of the P/N for the Epson screen. Check which screen you have by adjusting the brightness.
If when you adjust the brightness it switches with a fade effect, then you have a Novatel screen and you need the 2V6S ribbon. However, if it switches quickly and suddenly from one brightness setting to the next without a fade effect, then you have an Epson panel and you need the other ribbon cable.
So, I know it's been posted a lot in other places but I couldn't find like, a definitive answer as to if there are different digitziers? Am I just confused?
I would like to try and just replace the digitizer and glass over top of the LCD, my LCD works fine, the cracks are really thin and only a few going across diagonally. It fell from maybe 2 feet off my lap onto a parking lot surface.
I understand there is two LCD pannel types like you said, but are there two digitizer types/sizes?! for that ribbon cable.
I'm completely comfortable with taking it apart, I'm just worried I'll get the wrong part and find out the screen is also cracked and have to end up not using it for days until new stuff ships.... bleh
I've found digitizer+glass on amazon for 24-30$.
How do I adhere it to the LCD though, says doesn't include anything to do that.
EDIT: Found this gem: http://www.durapowerglobal.com/HTC-EVO-4G-Digitizer-Adhesive-_p_1166.html
Adhesive wont be a problem I just need to know about the glass/digitizer
EDIT2:
OKAY, if you want to ignore all i've said so far here is my real question of what I need to know.
http://www.durapowerglobal.com/HTC-...iginal-With-Installation-Adhesive_p_1103.html
Is there only ONE digitizer/glass piece on any given HTC EVO 4G? Or is there two different types like the LCD?
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

Recently my play with no recent modification + stock kernel + treated always with care started to light the screen less than normal (but still working) and now the screen is totally black, it only vibrates pressing the power button.
I tried flashtool many times but nothing.
I searched in the forum and probably is a trouble with the flex cable (also cause sliding sometimes changed the intensity of screen's light), but how can I be sure that is exactly this piece? Also I'm not so good at taking apart phones (but i'll try if i'll be almost sure that is the flex cable)...
No warranty (too old) and I don't know how much i'll pay at sony center...
I was always afraid about the slider cause too shaky in my opinion.
"sliding sometimes changed the intensity of screen's light"
Most definitely your flex cable. It needs to be changed.
Yeah... I only have to cross my fingers cause if it's not the cable I don't really know what could be...
Is there a way in case that works to increase the new flex cable's life? I don't really want to fight with this anymore...
Get a new phone.

I'll miss the gamepad and all emulators too much...
But surely i'm not going to spend a lot of money on the play.

Black screen is a sign the flex cable broke. On the other hand by the time you replace something else might of broke. If you saw a disassebly video on the xperia play you will literally take the whole thing a apart including the gamepad.
Good luck while replacing flex cable.
I changed it on my phone and on another 2 of my friends, it is not very easy to do, but still better than trash your phone
I can give you little tips to make it working longer as I did on mine.
PLACE A STICKER ON A CABLE on one or on both sides, you can cut a sticker to make it fit the most to cable and you can glue edges if needed. It is good to prevent from scratching and breaking cable caused by sliding phone.
Tips while you repairing your phone:
When you are going to put Flex cable on its place, you should perfectly fit that three little 'tails' to its holes if you don't your display will touch a digitizer and make a spots on your screen.
And after you connect flex cable with motherboard try to press the cable the most you can 'under the motherboard' because flex cable is getting a damage if you don't do this.
Now i have time to replace the flex so i'll try and see if the phone will work.
Is adhesive tape good inside the phone? Or is insulating tape (that is thicker than adhesive tape...) better? Or other/nothing?
PS: Did it! The phone works good :good:
the touch screen does though, annoyingly so, I can myself making a phone call trying to get the screen to display. The contacts at the ribbon for the display are all good and intact, both sides, I know cuz I've ruined them accidentally twice on two motherboards so I'm very careful now, board was tested good before I bought it on ebay, connector fully seated and locked... are there other points on the motherboard that effect just the display? Any you guys in here get this deep in this phone? This is the worst phone to dismantle. How to troubleshoot touch screen good, but no display?
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
