How to Figure out if touchscreen or LCD or both are broken?

Hello Friends,
yesterday when i saw the screen of my xda exec i saw a big black spot on the centre of the screen, not sure how it happened. i can still make calls from the phone.
but now i want to figure out whether i'll need to replace touchscreen or the LCD or both but i dont know how to figure out which one is broken.
Any help will be really appreciated on this.

Chances are
if the touch capability is intact, it's your LCD. The opposite, where the screen looks fine, but the touch is gone, would be your digitizer. However, unless you know how to replace a digitizer, I recommend getting both, LCD and a digitizer in one unit, rather than attempt to assemble the screen yourself. Which, judging by your question, is likely to be the case.

I would only iterate what enigma1nz had to say . It's at least your LCD at fault, but buy both as one unit. Or, buy a Uni that guarantees a working LCD+Touch pad (ie, a Uni with only a broken broken mobo/usb/doesn't boot etc) from eBay or the like.
First of all, I would just take the screen part of the Uni apart and check all is tight when replacing, as if the LCD has no obvious cracks, it's very likely a rubber-strip contact or similar.
NB. If anyone is interested in purchasing a fully-working Uni (brand new casing), with a non-functional touch/digitizer (guaranteed working everything else incl. LCD), I'm about to put on eBay. (PM me)

[Q] Sony LCD replacement screen.

Long time stalker, first time poster.
Cracked my LCD, been looking online for a replacement screen. Unfortunately the only one available is the hitachi version. I've been looking for the sony version with part number: 60H00523. Looked through american, german, uk, taiwan and some chinese websites to no avail. Am I screwed? Anyone with the same problem with a solution?
I have been using my glacier for the past couple months and have been terribly sad that my slide is sitting there in pieces collecting dust.
I might just give in and buy another slide and hope that I get the sony version.

Cracked LCD. Need the Sony version. Where to buy?

Well doing some quick looking online it seems that the Hitachi version is the only one... and on every listing for one on every site it mentions the sony version and the S/N for it, but not where to get it. I will try and look some more for you though.
Edit: Ok... So I even found one for the Toshiba version???? But still no Sony version... I'll keep looking though.

I really do appreciate the help.
I thought I was doing something wrong but the sony lcd is no where to be found, to my knowledge. I went as far as to buy one of the hitachi lcds and tried it on my slide but the screen wouldn't even power on...
It looks like the only solution is to buy another slide and hope I get the better of the two screens and use my old slide as parts.

That may be the best option... And it seems that the desire s uses the same screen? So maybe that may be helpful, but I can't find any trace of the sony version anywhere... Only the Hitachi version and even a site that had the Toshiba version...
Edit: I found this... http://www.mengtor.com/product_show.php?category=699&pid=3463. Idk if it is the Sony version or not you may be able to call and find out, but it is a bit on the price side at $125...

Thanks for the help Marc.
I'm typing out an email to HTC support at the moment in hopes that I'll get some answers. I'm assuming that I can get my current one repaired by going straight to the source. HTC apparently offers repairs if I send out my phone, but depending on their answer/price I may go with that or just shell out and get a new one.
Side note, the sony version is S-LCD and the hitachi is just a regular LCD.
Why????????????????????????????????????????

That one is the glacier/mytouch 4g lcd unfortunately.
The backing of the hitachi version is similar but the sony version looks like the attched picture of the original broken lcd.

Good luck! . And I did not no that there was a s-lcd version and a non s-lcd version. Wouldn't that be fraud on HTC's part, since they advertise it as having a s-lcd screen if the Hitachi version doesn't?

Well if no.luck i have a old mytouch slide4g for salr dont use anymore busted speaker, willing to sell for cheap, i just use it to play with different roms PM me if interested

I am in the same shoes like you are. I need the Sony version as well and I can't find it. This could be "it", I am not sure though: http://www.repairsuniverse.com/htc-mytouch-4g-slide-lcd-screen-replacement.html. I just inquired about the P/N number, I'll let you know what I find out. Mine actually says P/N 60H00532-00P

I just found this one that matches my P/N number, it's for the HTC Rhyme though. Hmmm. But it looks like the one I need. It's out of stock right now http://www.parts4repair.com/htc-rhyme-lcd-screen-60h000532-version/ I just inquired about the availability and the price.

If you guys ever get replacement screes, please take pics when replacing!

I guess I have found the needle in a hay stack
I received an email back from repairsuniverse. They said that their screens are all Sony LCD screens with the P/N number that I need (H6000532). I placed an order with them a few minutes ago, I'll let you know if the LCD screen works once I receive it.

Disassembling the MyTouch 4G Slide is a SERIOUS pain. I broke the LCD doing it and I have taken apart a lot of phones, the MyTouch 4G Slide was my first (and last) attempt to do that. They used so much double-sided foam adhesive that there was NO way to NOT break the LCD despite heating the back with a heat gun.

How do we know what screen we have? I have a retail launch device (July 26 or something).

I guess the only way to find out what P/N you have, you would have to see the LCD when the phone is disassembled, unless there is a way to find the part number through terminal emulator or adb.

I have disassembled my other phone (n900) plenty of times, and I never anticipated that the sticky, would be so sticky!
I dropped my mt4gs in my coffee... and wanted to clean it out on the inside, but this ended up happening. I know the phone still works, I can make calls with the genius button and all, but also, in the process of ripping my lcd, the ribbon for the digitizer snapped off too. And now I have to replace both, SO....
I'm very interested if repair universe supplies the right screen as mine is the sony version as well.
I'll be waiting to see how this goes for you.

The disassembly is a pain, isn't it? I have taken apart HTC Sensations, many MyTouch 4G's and I NEVER even had any problems comparable to this.
Well, the LCD arrived on Thursday and I was really anxious to install it. Once everything was reassembled, I turned the phone on and - BLACK LCD. Now I have to go through the process of getting a Return Authorization, sending it back and getting an exchange, hopefully a compatible one. The LCD I received didn't have any P/N number on the back. I went through a couple of emails with them, requesting the correct P/N number to make sure that this didn't happen. Sigh. I'll keep you posted how it goes

Thank you for your research. I look forward to your progress.

same problem
Thanx for posting your experience. I'm having the same problem. I now have 2 MyTouch 4g slides that I Vann it find lcd's for. Ordered one from USMobileParts and black screen. I do have the part# for the original screen but it didn't match. And when I inquire about the part#, the sellers have no idea that there are more that just one screen available for this phone. Very frustrating!
But I was able to repair 3 of these without breaking the LCD. It's a real PAIN!

I think I found it!
I think I just found a website that sells the Sony version of this LCD. Here's a link: https://www.gounlock.com/details.php?itemId=7782
They specifically say that they have the Sony version and note the differences between the Sony and the Hitachi versions. It seems the Sony version has a line near the flex cable. The Hitachi version doesn't. I'm going to call just to verify and if it sounds good, I'm ordering at least three. I got this info from the folks at injuredgadgets.com Great guys.
I'll post back and let you know how it works out.

Why can't we finda ANY of the sony ones? Have we heard of anyone successfully replacing one of the hitachi screens and it worked? Hmm, maybe more than just the screen got damaged in the process of opening it? But it is interesting that no one supplies the screen..
I don't know. I just want to turn my pile of parts into a phone again.
Thanks everyone for your research.

Touchscreen dead?

Our offices have many TF300's and I received a few that have completely dead touch screens. They're not cracked, and they look good.
I've done a little research on here and the only touch screen information that I can really find is on replacing cracked ones and the problems some have with the G01-G03 digiz and the firmware of the TS board. The digitizer and board are both original, it's just like the digitizers died.
Anyways, I was hoping there have been some problems and solutions that some have found? A bad common ground? Some kind of firmware issue, etc?
If it's worth noting, some are G01's and some have no text printed on the flex cable above the white label.

Broken touchscreen :eek:

Hello dear community, my dreadiest fear just realized today :
my X2 decided to make one with the concrete...
luckily, both with my heart, only the touchscreen shattered from this unholy union.
So now I want to replace only the broken thing (less expensive) with a replacement part I found on aliexpress (25 € for those wandering), BUT I was unable to find any clue about the separation of the LCD and the touchscreen :
Are they inextricably bound together as the galaxy S series are ?
Or are they just attached with some tape as any good reparable phone should be ?
I was also wandering whether the screen parts were the same between the X1 and the X2 !
If you have any material showing how to proceed with the separation, and care to share them, I'd be in your dept forever !!
Boujou bien !

The disassembly should be the same as the X1 video here:
https://www.youtube.com/watch?v=8NOG1SISbKw

Yes I have seen this video, but it is only showing the removing of the screen/touchscreen from the phone, not the separation of the LCD from the touchscreen (they are both broken in the video, hence no point to mess with them !)

They are fused together so it's not even worth trying to remove them. 99.99% of the time you won't be successful.

Good to know !
I almost succeeded once, with a heated bench, But I'm not willing to try that again…
Did you have to fix yours already ? Any clue about backward compatibility with the X1 assembly (20 % cheaper !) ?

I Sat on my Huawei honor X2 -Screen is not working Properly
Hello (posted this in wrong area a few weeks ago)
I sat on my X2 GEM-703L under several pillows - bend was 1/2 inch - the top & bottom were 1/2 inch lower than center . I carefully bent it straight (there is a small kink in metal frame right side just above center button. Everything else seems to work beside the screen. *** I will push "4" and the key adjacent character is recognized, also it will type on its own or type 3-5 characters when I only pushed one...
Questions:. Does this sound like touch screen Replacement will fix these issues??? Or is thier additional interface hardware attached with the touch screen, or both?
- I really like that phone - hoping it is not a lost cause...
Thanks for your help

Hello Gary, sorry just saw your post.
I Think this might be fixed by a change of screen, but the problem might also come from the bent frame too.
For the tactile to work properly, and not register wrong input, the screen needs to be grounded and I think also calibrated to the phone caracteristics. If you just replace the screen, it's environment would not be the same as it is suppose to be anymore (frame with a kink) hence there is a risk that the new screen might reacts weirdly, registering ghost input etc... Because the screen might not rest flat on the support frame, and the contacts used for grounding might not be working anymore.
I have a spare screen that I*just bought for mine, unfortunately my problem seems to come from the motherboard, so the screen is useless for me.
If you want to give it a try, and live in the US, pm me !
If you don't want to do it (the screen comes without a frame, so you have to use your old one)
I'm willing to buy your phone to try to save mine ! :angel:
Best,
Quentin.

Screen damaged what should i do

My sister just broke her moto x pure.
The display works, however the digitizer do not works correctly. Cannot post pictures because the wallpaper is containing private information and i cannot change it.
She cannot use the entire screen.
For example on the lockscreen, she cannot use the 8. And the other digits works very badly. So she cannot unlock her phone.
What should I replace (screen, digitizer...) and where should I find the replacement part ?
Thank for your help

You'll need to replace both the digitizer + display as they come together. If you are good at repairing phones, you can get the display from eBay or else send your phone to service center if you don't. I would suggest you to send it to the service center.

You could use a USB OTG cable to connect a mouse and thus regain control of the device in order to clear any sensitive information prior to having someone fix it. I have bought and fixed several Moto X pure edition phones with cracked screens for family members. Most of them did alright, but one phone had the screen replaced, then a cow stepped on it. Although it didn't crack, after a while parts of the screen stopped responding to touch. The screen I replaced it with has not been damaged at all, but parts of it have stopped responding to touch as well. Sometimes I wonder if these phones don't have a particularly weak and easily damaged screen. I sometimes get my replacement screens from GadgetFix. If you fix it yourself make absolutely sure that you get a screen+frame assembly. It's just a few dollars more, and totally worth it. And be careful when you transfer the speaker grill trim to the new screen that you don't press hard enough to crack the screen.

Thanks you, I think I will change the screen and the frame.

Is this what I should buy ?

The screen that you posted does not include the frame. I briefly looked on eBay; you might find one with the frame included for a few dollars less than gadget fix, but for simplicity I just linked this one. On the back side of the display you will notice the screw inserts. That is what you need to look for.

Thanks !
Could you point me to a tutorial or a video explaining how to change the screen

I believe that Ifixit has a whole teardown tutorial for this phone. If not just search YouTube for (phone model) screen replacement, watch it a time or two, and then pause it while you do each individual step. If the first video you watch doesn't explain things in an understandable manner just watch another one. It's been a while since I searched for one, but I think there are at least a few good ones.
