First time poster in the forum here. Basically I opened up my xperia play to replace the screen which was successful.
Unfortunately there was a spec underneath the screen bothering the hell out of me and so I took it apart again to clean it.
This time however once I put it back together it won't boot up and the only signs of life are a red flashing light.
I have tried swapping batteries and sockets. Still no change.
I hope there is a genius out there who knows the solution to me being a perfectionist.
Cheers.
You need to make sure all the connections are intact:
-the connection between the screen and the motherboard on the top right
-the small connection between the gamepad and the motherboard
-the flex (main) cable between each half of the phone, you have to press the motherboard down into the connector and hear a "click" to snap it in place

It was the motherboard hadnt got that click this time round. Unfortunately i think i have done something to the digitizer as the screen isnt responding to touch now.
The phone is destined for the bin unless there is a way to unlock the screen without the side swipe, as i only use for emulating.
Cheers for the previous help

Hallo to all!
i've already tryied to search this topic in all the forum, but didn't find anything...pls tell me if something similar already exists!
so my problem: i have a touch pro 2 (RHOD100), and the last week i broke the touch screen (due to accidental heavy pression on it)...all works, but no TS function...
so (here starts my trouble) i decide to change by myself...i bought a new one (only TS) on ebay and make the change....
no problem with the hardware change, but now my display stay white...
some consideration:
- OS start with no problem (start sound and button sound)
- all flats are plugged correctly (checked many times)
- the backlight of the lcd works well (low light after some time)
some help? maybe i forget something important?

When you changed the touch screen did you remove the flex cable that connects the upper half of the phone to the motherboard? Are you sure you didn't break the LCD screen itself?
hallo,
yes i remove the flat, and plug back again where changed - when i press on the TS (with white screen) i can ear the "tap"
i cannot be sure, but it light on...i think is enought...or not?
thanks for you're help!

It looks like like either the flex cable got damaged or it's not plugged right. It could also be the LCD flex, where lcd plugs into the small connectors under the four buttons at the bottom of the touch screen not being connected properly. Did you lift the small levers where the flex cables go into the mother board or where the lcd/touch screen gets plugged in or did you just push them in?
i lift the lever where pull out the flex, and pull it down when restore the connection... and i'm almost sure about connection, also because them are so "stricted" in the plug himself...
but i find really strange that the lcd is on (completely white), you don't think so?
also if it is damaged, should be not white...or maybe, as you say, a flat problem?
this evening i will re-open it for a check...i don't know what else do...
maybe i will try to buy a complete kit (TS+lcd)...
i will surely let you know

The screen being white, means it's receiving power but not video signal. There coud be different reasons for that. It happened to me couple of times. What I did was lift the connector lever, pull the flex connector out (where it connects to the motherboard) just a tiny bit and secure the connector with the lever and it worked. If the flex cable is going bad it could be that just one line or two are going bad not the whole thing, thus still delivering power but not video signal.
If your problem is with the flex buying a new screen/digitizer will not fix it. When you screen is white does it go out if you slide out the keyboard?
hallo,
sorry for late answer,
i make some test with flat, but the result is the same...
the screen always stay white, but i can ear the start sound, the pression sound, etc...so it seems it's just the lcd...
maybe i can try to buy a complete set lcd+ts?
thanks for answer

I could be wrong, but I think it's the flex cable that is bad not the LCD screen itself. The flex cable has several small thin lines, what is happening is the power is getting to the LCD screen but the video signal is not, so most probably one of teh video signal lines is broken.
Hello guys,
Around a week back, my MT3G slide touch screen got unresponsive for a while. I rebooted around 2-3 times and thankfully the touchscreen worked fine.
Now, I am getting this unresponsive touchscreen more often and I have to pull out the battery from the phone and turn it on again. The last time this happened I had to do this about 8-10 times before the touchscreen would respond. I have no problems with my keypad, 4 buttons or the trackpad, just the touchscreen
I also did a factory reset and erased all the data that I had on my phone and SD card.
EDIT : I just figured that the touchscreen sometimes starts working if you slide out the keypad. But once the keypad is slid back in, it's back to being unresponsive.
My phone is out of warranty so I can not get a replacement I think.
Does anyone know what could be the problem for such frequent touchscreen unresponsive behavior. After a couple of reboots, everything returns to normal.
Any ideas ? I would appreciate any help..
Thanks a lot...
you got a broken ribbon
Hi there,
Do you mean the slide rail flex cable or the digitizes flex cable ?
Thanks
flex ribbon cable
I would say it's the flex ribbon cable which connects the motherboard piece to the screen and home button piece. I've purchased several "broken" my touch 3g slides from ebay that had either the screen shift problem when the keyboard was slid out or screen that was unresponsive/wouldn't come on. Both problems were fixed by purchasing an inexpensive flex ribbon cable like item 170747702766 on ebay. I watched a video and followed along on youtube /watch?v=-jgFHuVWlig (stop at 7:27 and reverse the process). However, my most used mt3gs is now starting to have the screen shift problem again and needs a new cable... it didn't last as long as I had hoped.
Did you try any custom roms?. reflashing/updating the device?
I guess it must be some driver issue!..
i have the same problem.
Could you fix it?
Seems to be a common issue. I've described the process of replacing the flex ribbon cable here - it's not a rocket science. Or just bring the phone to a serviceman who will do the same (if you lucky enough he could even have a spare cable, but I'd advice you to have your own bought from ebay to be sure).

Thank you for the information but another questiion that I do have is where would one get a serviceman that would repair or help repair a phone, usually the technicians are attached to the different cellular carriers and if one dosen't have a contract with them they are not likely to help repair your phone even if it is for a fee. Do you know any serviceman?
Hello, I saw that someone else asked a similiar question before but they did not word the question correctly and got little help.
On my HTC EVO logic board, there's three tan "ports" (I don't know what they are actually called). One for the front camera, one for the LCD, and one for the front panel.
While walking home one day, my screen started showing a dark spot. The spot got bigger, and I decided to take apart my phone (something I'd done before a few times) and try to clean things up. I put everything back together, and the LCD would not come on. After numerous tries, I finally decided the LCD was damaged. As I went back in the phone, I saw that regardless of whether you flipped the black tab on top of the LCD tan 'port' back or forward, the cable was capable of being pulled out, e.g., it was not secure. At the time, I thought nothing of it, but now that my new LCD should be here, I'm worried.
Is my LCD not working because the 'port' is broken? If so, what can I do to repair it? (I heard it is very difficult). I'm worried, because I paid a lot to buy a new LCD and will be unable to send it back.

Also, my front panel cable never sits 'perfectly'..that is, I have to connect everything else first, and then try my best with the front panel. The tape does not stay down flat completely.
These sorts of connectors can be fixed,but there is quite a bit of skill involved. Upload a picture and I can tell you better how hard it is. What I can tell you is that you probably cant do it yourself. I base this on the fact that those who have the necesesary skils will instantly know its going to be a pain. In fact,its easy to screw it up ,and sometimes you do,even if you DO know what your doing. Since I dont want to take my phone apart,Ill need to see a picture of it before I can tell you anything more. One thing to keep in mind is that sometimes the ribbon cable CAN be pulled out anyway,and is making good contact and there is some other problem. If you have not installed the new LCD,install it and see if it all works. If so,your good to go. As a general rule,the connectors are delicate and its not a good idea to pull them out. In fact,dont disconnect them if you dont have to. They have a limited number of connect/disconects they can take and they are very easy to break.

Well, I don't really have a means of taking a quality photo except with my computer webcam but I'll try in a second. I can't really show you because there isn't much to see. The little black bar that flips up and down to 'lock' the port is ineffective; the cable can be pulled out regardless. I know I can't fix the port/connector by myself, so I'm hoping that's not the issue. You have given me a lot of hope though. The new LCD should be here by Wednesday at the latest, so I'll be able to test it then.
Does my front panel affect the LCD? Since I dropped my phone on the corner, even with a new panel it does not sit 'perfectly'. I don't think they're related though.

I dont think so. I bet your ok. Just dont keep playing with the connector. I know,Ive done it. I sit there messing with it,wondering,is it broken? Is it good? Then the little black peice comes off in your hand or the plastic breaks and "well its sure broken now!" Remember,that little latch does not so much hold the cable in place as hold the cable against the contacts,if its making contact,its good to go.
Hi, all. The new LCD I receieved did not work. There are very minor differences in the two; such as some type of blue gunk on the silver part of the LCD, the connector is more of a dark orange on the new one while the original is a yellow-orange, etc. Also, again, the connector does not 100% fit in the slot. It goes in, but a small corner sticks out a bit and you have to either hold it in or clip it in [which I can't, because the black clip is broken].
The only possibilities I can think of are
A] Because the little black thing is damaged, no LCD will work in it. Therefore I need a new phone.
B] The LCD does not work.
C] The LCD is the wrong size.
At this point I want to just give up and get a new phone, which is very heart-wrenching because I love my EVO and I doubt I can afford the only other phone I like, the Samsung Galaxy S II Epic Touch 4G.
Is anyone able to identify what connector is used on this phone for the LCD? I broke a pin on the connector while trying to repair a cracked screen. I would like to buy it and re-solder it on to fix the phone.
Can someone link the correct connector maybe from digikey.com?
Broken latch
I too have a problem with the connector... the plastic part that connects the ribbon cable to the main board has broken. There must be a place to buy these tiny plastic latches... does anyone know? Your assistance will be greatly appreciated!

Hi everyone.
After a sudden heavy rain, I got some water in my Gnex. I tried the old bag of rice trick, only to find out the USB port was not functioning any more, neither for PC connectivity, nor for charging.
Following the advice of a person I no longer consider my friend, I tried spraying some Isoprpyl Alcohol in the USB port. It did get it to work correctly, but it damaged the digitizer, meaning I get random touches on the lower part of the screen (where the Back, Home and Recent apps buttons are).
I took the phone to a service centre where they tried to clean it, but the issue remains. I'll go there today with my wife's phone to see if it's indeed a touchscreen issue or a motherboard issue. I'm not sure if I want to invest in a new screen (over $100 + maybe a new back cover since the current one has quite a few scratches and cracks) and I'm thinking of maybe upgrading to a Nexus 5 or Xperia Z (the latter being waterproof).
The question now would be, could I do something with the hardware? Like, root it, connect it to my wifi and use it as a web server, or connect it to my TV through an MHL adapter and get a "smart TV". Can I get it to ignore touches on the screen completely, and only accept an OTG/bluetooth mouse input?
Any idea is welcome

One day I got caught in a storm having my Gnex in my pocket. Vacuum and rice tricks didn't work completely, as the phone was working properly besides recognizing the sim card (Mboard issue). What I did was buy a broken screen nexus off of Ebay, and exchanged the screens.
Now I have a fully working mobile phone, plus an MHL connected - XBMC enabled smart TV box, connected with bluetooth mouse/keyboard.
Question: Why would you need to ignore touches on the screen?
As I said, after spraying the USB port with isopropyl alcohol, it appears to have touches all over the bottom part of the screen, as if someone was constantly keeping 3-4 finger and touching away at the soft buttons. Cleaning the phone in a service centre did not help.

Sorry, I missed that info. Try searching for 'touch blocker' in Google Play. Don't know if that would work on a Gnex though.
Another (hardcore) idea would be to disconnect the screen altogether.
Yesterday i dropped my device from one feet. It turned off and i turned it on.
Now lower part of screen and capacitative buttons dont work. i will attach a image(non-working area outlined in red)
My warranty has expired so i cant exchange it for a new one. What should i do? Can i fix it by myself?
Please help me

Hi,
Only thing I can think of is that somehow it has damaged the cable from the touchscreen or the tiny wires that feed into the cable without damaging the screen. I came across a brand new screen I was replacing once for someone that had a similar problem where the bottom left hand corner wouldn't respond to touch unless there was firm pressure on the screen to create contact, and this was a brand new screen. It could also be that the touchscreen connector needs to be pushed back onto the board if it's come a bit loose.
If this is the problem, you can fix it by yourself although I'd have a good look around youtube, there are heaps of DIY videos of how to replace screens. If you do go down this path I recommend you replace the touchscreen/LCD/LCD frame in one go, as it's generally already pre- assembled the only thing here is that there are 3 brands of LCD's HTC used with the phone and they aren't all compatible, and you can only tell by pulling down your phone and looking at the LCD flex cable colours, and the other thing is that the screens that are available aren't always the same quality as the original. If this sounds to hard your best bet is to take it somewhere and diagnose the problem just in case it's something else
