I think this is the right section to post this question. If not, please warn me.
Recently I droped my phone (Sony Xperia J) and broke the LCD, then I turned it on to check if I had just broken the LCD or if the digitizer was also broken.
When I turned it on, the image was alright (despite the huge cracks on the LCD) but when I tried to insert the SIM pin, the digitizer seemed to be not working: when I first pressed the screen, instead of detecting (let's say) the digit "4" it detected the digit "9". I tried to clear that wrong number but apparently the digitizer couldn't detect any other touch.
Is there any way to check if the digitizer is broken? I was thinking about removing the LCD and trying to phisically test the digitizer by turning the phone on again and directly touch the digitizer.
Do you think that's a good idea?
You probably have problem with touch screen if the digitalizer is ok. So you just need to change touch screen.
Good Luck!

Well, I opened the phone and removed the LCD. Replaced everything and turned the phone on without the LCD. The image is 100% ok but when I tried to press something (directly in the digitizer) nothing happened. Does this mean that I have to replace the digitizer or does the digitizer need the LCD to work properly?
For the record I noticed a tiny scratch on the digitizer, probably made by the broken LCD.

LCD is digitalizer, glass top part is that shows/received touch so if lcd is working you just need to replace the glass
Good Luck

Oh I was confusing the two terms. Anyways, does that mean that in order for the touch to be recognized I need the glass? As I said, I directly touched the digitizer (the LCD as you said) and didn't got any response.

That's correct, that's why it's called touch screen.

Ok, thanks a lot for your help.
Just one more question. How fragile is the LCD? Because when I was trying to test it, I could see that there was two tiny scratches, but one of them was deep enough for me to feel the protrusion. Do you think that can be a problem?

For touch not working No. And it depends it different from phone to phone but don't touch the lcd (digitalizer)
Good Luck!

Ok, in my ignorance I touched the LCD this time in order to check if it detected my fingers but I won't do it again
I'm gonna clean it with some dry cloth and then replace the LCD.
Thanks again for your help.

So my g2x front screen glass was broken. Replaced it with a new one and after reassembly and powering the phone on, its responding to all my touches but the screen is very distorted. It looks like a 90's crt tv going crazy, with the noise on the screen if you know what I mean.
Any ideas? Or did I just seat the digitizer wrong or the ribbon on the screen is off by a pin or two?
Try resetting the connections. If it's still like that it's a low quality digitizer and I would try to return it.

If the digitizer is responding fine then make sure there is nothing pushing against the LCD (anything between the LCD and digitizer) and the connections are seated correctly.

Thanks for the replies. I cant find the rubber seperator thing could that be the problem? I looked at the LCD and nothing is in between it and the digitizer but it appears to be loose. All connections are seated correctly.
If the LCD was being pushed from the backside thats metal would that be a problem?

If the LCD is being pushed it shouldn't be a problem. If a piece of metal was touching the digitizer, then you'd have interference which would cause ghost touches and poor accuracy.

Okay so I took it apart and reassembled it like 5 times and I'm getting frustrated.
Basically the issue is the screen is all wonky after I power it up. The picture was perfect with the old digitizer that was cracked and had water damage, how is this possible? But when I plug everything in I get the wonky picture.
So is it my LCD or the digitizer?
By the way all touch functionality works 100% so whats the deal... because the LCD was working before with the broken digitizer that had no touch working lol.
You could try to unplug the digitizer and see if the picture becomes normal. If so, it is the digitizer.

It seems then either bad LCD or connector, or even hardware... IMHO you need another phone to further rule out any possibilities.

i didn't know that this whole thing would be so difficult so i have ordered only the glass

I have opened the phone until the touch
http://i.imgur.com/GTniJqk.jpg
i tried removing the glass properly for one hour but i coudn't do it, so i breaked the glass and twrow it away
http://i.imgur.com/RvjGhEJ.jpg

is the touch damaged? if not, what should be my next step? remove the black plastic?
That glass you ordered is a touch screen (digitizer) itself. You broke LCD. Turn the phone on (obviously you can do it without TS) and see the damage for yourself. But most probably LCD now needs to be replaced as well.
btw, I think you have overlooked some clips or disassembling points as LCD is generally prone to damage, therefore no force should be used when working around it. It's also possible that for taking out digiter you need one of these (similiarly as for iPhones/iPods)
It also looks like the connecting flexi strip on the bottom right corner is compleatly recked and torn. (3rd pic)
Best of luck, but those pics look like disaster to me.
Edit - the more I look at those pics the more it looks like u need a new mobo...

Do you see any cracks on the digitizer (Touch Glass). Also does touch works? If your touch works that means your digitizer is fine and you only need to change LCD screen.

Hi
I just replaced my screen at my Asus transformer 300 due to broken one, I have replaced 2 screen and at both of them I see a wired phenomena that the screen looks like it have an internal scratches\crack, it happened at both new screens which cause me to think that the problem is not the screen it self.
If some one had that issue or familiar with that, I will be happy to get any idea/help to provide that solution.
P.S I attached a pictures of the new screens after installation and turn on the device.
Appreciate any help.

What did You actually replaced? Was it touch screen (front glass) or display (panel underneath the front glass)? It looks like Your display is broken.

I replaced the front glass only, per your comment, this is the touch screen, what is the display you mean?

Here is how it looks like: front, rear. There is also option to get both as one piece.
Thanks for your fruitful answer, I replaced only the screen that connect to the front side of the display, I will try to replace it, once again, appreciate your effort.

I also should clarify that display is vulnerable to heat and pressure. So be careful with new one. Good luck.
Hi everyone
The issue is that my screen cracked, no reason, I didn't sit on it or in didn't crash in the floor, simply cracked in my jacket pocket.
Now the issue is that half of the screen is not responding.
Is that normal? A small crack makes the touch completely unresponsive?

Yes. You've broken the touch screen, what do you really expect to happen?

Yes, and many do have problems. I work with touch screen systems for my job, so know how they work and how damage can affect them.

I think mostly phones which have LCD and Digitizer fused together seize to work. Phones which have different LCD and Digitizer continues to work ..
