Check if the cable is attached properly.

yes it is : (
First off, is it the digitizer that isn't working properly, or the lcd? If it is the digitizer only, it is possible that you got a bad digitizer, that has happened to me several times with ipod screens. My suggestion would be to take it back apart and inspect the ribbon as best you can to check for small rips or nicks. make sure that nothing got into the connector receptacle or on the end of the cable. If everything looks good, reassemble and retest. If it still doesn't work properly, chalk it up to a bad digitizer and see if who you bought it from will replace it.

Hey Boys n Girls!
I made a mistake and bought off eBay a phone with a "not working LCD":
" This is a used HTC Desire Z smartphone. The item was dropped on water and immediately pulled out. The LCD screen doesn't work anymore as some cable inside is cracked. Everything works fine, touchscreen, menu and the device boots fine, you can hear the sound etc but no image. Anyone can fix this if you have an LCD spare for HTC Desire Z and the phone can be used and works fine, just the LCD needs replacing. Comes with original box, manuals and battery but no charger or data cable. I want to sell this fast so Happy Bidding!"
, also ordered already from two different seller LCD replacement screens neither of them worked. Backlight works on both but nothing else. Im quite puzzled what to do next...
Anyone got any idea?
Please let me know! THanks in advance!
Sounds like some cable is not working, rather than the two screens you've purchased! There is a guide somewhere here for all of that stuff. Best of luck mate!

If you could kindly link that guide, it would be very much appreciated! Thanks!
try searching for ribbon cable. You should prob just take it to a cell phone store. Phone geeks in San Marcos did my repair for 70. I was texting gf while playing golf in pouring rain.

The flex ribbon cables are not that expensive. If you were comfortable replacing the screen, I would say you have the ability to replace the flex ribbon cable without a problem.

Im going to order it tonight and give an update as soon as I got the flex ribbon cable.... I assembled and disassembled so many times already soon will be able to do it blindfolded
Also while you have it apart clean the logic board with denatured or pure alcohol and a soft bristled brush. Let it dry completely! That way it won't corrode further from the water damage!

I will do that since it will probably take like 2 weeks to ship the flex ribbon from China Thanks Man!

No prob cheap insurance plus it could even since a current or future problem I do this work for people can you tell lol. Denatured is best otherwise I think 97 is as pure as you'll find. Most stores carry the latter.
Ps be gentle no need to go medieval on it
Replacing the Flex Ribbon Cable solved my problems.... Cheers Everyone!
Hi there.I don´t know if this post goes here.Sorry if it doesn´t.I didn´t know where to put it
I was changing the digitizer on my Desire HD and I realize that that I broke the ribbon on the picture.Can anyone help me about what to do?Thanks in advance.
Sadly been there and done that....Only 1 solution-buy another. This process is next to impossible without lots of experience-parts are very fragile! Your best bet is to buy an entire assembly with the digitizer and lcd already attached. Much much easier, but not easy by any means still. Good luck.

you can fix that.
google ribbon cable fix and follow the procedure
(can't post direct link)
btw.
this you can't fix because the lines are simply too small

A bit complicated for me.I will buy another lcd.Thanks anyway.
Hi again.I change the screen but now the wifi won´t work.I can´t activate the wifi.It says error.It´s like i don´t have a wifi antenna.Any help?
wifi antenna
I think your problem is bigger than an antenna. The antenna is the same one as the gps antenna and is fitted in the panel around the flash leds. If you were to enable the wifi and just could not pick up any access points, then I would say it was your antenna, but if you are receiving an error, it is more likely that either the wifi module is damaged or somehow disconnected.
Do the rest of the radio parts work? i.e. GPS, Cell, bluetooth? Can you tell me exactly what the error is that you are receiving?

The cell,3g and gps are working fine.Bluetooh and wifi aren´t.When I activate the wifi I get an error message(it just shows "error").When I try to activate the bluetooth it just does nothing.

did you check flex ribbon connection and rips on flex.
(also check volume buttons)

You are right.The volume button are not working!I didn´t try them before.What does it have to do with the wifi?I will open it again.

not much, but it is simple test for the flex ribbon.
open the phone and check the flex connection too motherboard
worst possible thing is that you ripped the flex ribbon during removal from middle chassis
2 areas worth checking-the reciever jack at the top of the phone CAN be put on in the wrong direction-red wire should be towards the top of the phone, black towards the bottom. The long, all black wire running by the camera is the bluetooth coaxial cable and maybe not on its connector properly-kind of pops on when right-check both ends. It also could be damaged/pinched running up through the phone. It could also just be a bad component on the upper board and that whole board needs replacing-a pain after what you've done already.
bluetooth/wifi and volume buttons not working
I think yamFZ6 is right. You likely have a cable not fully seated or a damaged cable. Both the Bluetooth and wifi are on the same chip so it makes sense that both of them would fail together, the volume buttons are a separate module, so they are likely all on a single cable that has issues.
One last thing to try before tearing it apart again, do a full wipe and see if it works properly. This is a long shot, but worth checking and can help with troubleshooting if you cannot find any cable issues.
Good luck,
Let us know what you find.

Hi.Sorry for the delay.Been busy with work.I took some pictures of the phone.I don´t know if they will help.

Looks like the black wire (blue tooth coaxial) near the camera is in toward the battery area too far...battery would be pushing in on it every time and could have broken it...admit that's a long shot...but. Starting to feel like a new "upper" circuit board is in order...hope this helps

Do you know where to buy it?
I have seen it for sale somewhere out there but can't find out where that was now. I would look for a "parts" phone on ebay. usually you get more than a fair amount of usable other parts with it. I just did this for that exact issue plus I needed a 'mid frame'. I got just about everything else with it also as the lower, main board was the problem with that particular phone, Got a usable digitizer, lcd, case, extra wires, camera etc etc all for around $60. You also get the added luxury of more practice/expertise with assembly.

Hey guys, I'm back while I don't have my iPhone. Now I'm trying to get this damn phone to work again. R800x if you didn't remember. Now, every time I get a new digitizer, It doesn't work. I take the old one off and put the new one in, making sure all contacts in the ribbon are connected to the flex cable connecting to the logic board. Any suggestions to get this damn screen to work again?
Or if anyone has a working, but broken digitizer they replaced, I'll take it

It may be the flex cable, the little cable which connects to the digitizer is part of the flex cable i believe.

Except the front camera works (green and fuzzy with no quality what so ever, but works). That's why I don't think it's the flex.
Just replaced it with an extra laying around. Didn't fix it...

Ah sorry, I meant the front facing camera cable, the green and fuzzy with no quality seems to affirm this.

So my xperia play had this fuzzy screen problem, after I bought the flex cable and replacing it I powered up the phone and seems it was working. Although the touch screen went completely unresponsive(buttons and gamepad work though). So what could possibly went wrong?
EDIT:Touch screen was working with the other flex cable.
Well this might seem like common sense but...maybe the new flex cable is also bad? I dunno :|. Did you try reusing the old cable to see if the touch screen worked again?

I might try putting the old one (with the fuzzy screen) again and hear if it does the unlock sound.
Will update with my findings.
i think youre moved tochscreen cable from it's place.
When I disassembled my xperia play for the first time,
the screen digitizer was damaged by my mistake.
I can't sure that, but I guess it can be.
At that time,
the bottom of screen (about 1/3?) didn't work.
So I bought the screen digitizer,
and replace it today.
But the problem hasn't been solved all the way.
If separate into 6 parts the screen from top.
(For example the top part is 1st part.
And beneath 1st part is 2nd part.)
5th parts doesn't work.
But the bottom 6th part works well.
I don't want to buy else new screen digitizer.
Please let me know how to use my xperia play with any problems.
Please help me.
Thanks about reading my thread.

Are you sure it's digitizer problem? Maybe it's flex
I had similiar problem, but in my case whole touchscreen didn't work and it happened randomly on reboot
It turns out that when i was repairing my usb port i somehow didn't place flex cable properly and it was bended over that metal part of slider.
Once i reopen it (only the part with motherboard on it) and place flex cable properly, touchscreen started to work normaly
How old is your Play? When you opened it, does flex cable looks damaged?
Where did you buy your digitizer? If it was from eBay, you could ask for a replacement from the seller you bought it from.
Like Bakisha, it could be the flex cable. If you know the digitizer is working, it usually is the flex cable.

In fact, the flex cable of my xperia play looks a bit little.
The black color had been painted on cable wear a little.
So do you recommend me to replace flex cable?

Well, you could open your Play and see if flex cable properly placed. Open slider and put that white plastic inside metal frame. Put back dpad part of phone back, but keep an eye on that white plastic, it have two holes in motherboard to go into, then screw those two screws on motherboard (so it will make flex cable plug in motherboard - look if jack is now properly inserted
Close it and try it.
If you again have problems with touchscreen, then you have two options. Replace flex or replace digitizer. It's hard to say wich is faulty...
