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] Broken LCD Glass :(

Anyone know where I can get a replacement LCD glass for my Desire HD
I believe it's just the glass as the screen seems to still work.
If there's a place in or around London that can replace it for me even better, if not anyone know how difficult it is to replace.
I've noticed a few places on Ebay (China/HK) selling digitizers and complete LCD's but ideally I want somewhere in the UK.
thanks

Hi,
I went through a similar experience less than 2 weeks ago, you can even see images here: http://forum.xda-developers.com/showthread.php?t=834335
I rang around several places, none could commit to using GENUINE HTC parts. The only people I found were: www.htcrepairs.co.uk/ - and they even offer a walk in service whereas I found most others did not.
Unfortunately they don't have the parts I require in stock, maybe you can try them.
At the moment, they're the only people I've found in the London area that I'd be willing to give my phone in to...
Did you have any luck with finding anyone else?

Maybe contacting HTC? They can probably repair it for you but it can be pretty expensive though.
Maybe you got some pics?

You could try, as said above, get the glass/screen from eBay.
Repaired my SE K800i with it, where the glass could easily be removed and the new one could be installed within 5minutes.
Don't know how the HTC will disassemble though.

I'm going to try this place on the way home from work: http://www.spsmobile.co.uk I'll let you know how they go. They've got the parts and will charge me £60 for either the lcd or digitzer including fitting.

Here's some pictures. I think they'll get away with just fixing the glass, although it looks bad the lcd still seems to work ok.
Can anyone recommend a case surround?

How did it go?
Did they fix it whilst you wait, or retain the device to work on for a day or two?
More importantly, are they using genuine HTC parts ?

They fix while you wait, they're near Staples Corner (which is a bit of a walk from the tube at Brent Cross).
I need to go back tonight as they messed up and thought I had a Desire and not a HD, they're hoping to get the HD part in today, they're charging me the Desire price.
According to their website they use official parts, but who knows.
Warranty
* We give 3 months warranty on every repair excluding liquid / water damage and physical damage
* Every warranty handset is security sealed. Tampering with the security seal will void the warranty LCD / SCREEN warranty. We fit original screens only and they are security labeled
* Every handset is tested for 24 hours and comes with engineers report

I plan to visit these SPS guys tonight. Lets hope they manage to fix my phone.
I'm hoping to wait around so I can ensure genuine parts are used...

SPS didn't manage to get a Desire HD digitizer for me, they've got 1 on order. They're a little difficult to find (at least they were in the dark) they're behind Staples industrial state, in room 207, small little office. They seemed ok though they.

I'm back!
Got my Legend fixed earlier this evening by these guys: http://www.spsmobile.co.uk/
They were one of few who were adament they use genuine parts [they allowed me to inspect the parts before installation] AND allowed me to wait whilst they work on it.
Abolutely disgusting/poor customer service and general attitute towards their customers... though the main thing is my Legend is all well again !
Oh, it cost £70 for display + digitizer + installation.

U didn`t look for it enough Check this thread: http://forum.xda-developers.com/showthread.php?t=883444

Thanks but I do not see a complete teardown guide yet. Looks like the guys on the other thread are working on it but nothing detailed enough. I need to know how to replace the digitizer, looks like not body knows how to do it yet.

need a lcd, touch pro 2 fit the 7 pro?

Hi, i am in desperate need of a lcd display for a 7 pro but they are seriously hard to get hold of!
I have looked on ebay and theres only ones from HK or China and even then the sellers feedback on screens is poor!
I have phoned countless repair shops in the uk and only a couple claim to be able to get hold of the screen but then demand that they fix the phone themselves and a stupid fee and will not supply the screen to me.
one thing i have noticed it that the touch pro 2 and 7 pro screens look identical apart from the colour of the ribbon that connects them to the main cable that goes through the slide body.
there is no visual difference between the screens or connector cables other thab colour and they have the same specs also-
480 x 800 pixels, 3.6 inches and a 259 ppi pixel density
Does anyone know if they are actually interchangeable or not? i cant find a screen anywhere and my wife is not pleased with me right now as ive only just got the phone and a broke the lcd trying to remove the digitizer even though i was ultra carefull and used lots of heat, please can someone help!!!!
Thanks, Steve.

Hello! To most simply answer your question, no. The screens are very different despite looking similar. The old TP2 screen is not multitouch and WP7 requires this. Also, the old screen utilizes a stylus while the newer 7 pro screen doesn't even recognize that type of touch.
It is your phone after all, so if you would like to try this that's your choice. However its too much effort to affix the ribbon to the pcb to even make it worth it. My old TP2 has a cracked digitizer which I have a replacement for, but the ribbon is machine pressed onto the pcb and reattaching this connection would be very difficult without the type of heat/pressure used in the manufacturing of the phone.
If you decide to try it let us know the results!

I'm sorry, I just seen you said the lcd itself, I thought you were meaning the digitizer screens.
That being said, maybe the swap will work, as long as they hook up the same?

i found a seller with genuine touch pro 2 screens who is willing to take it back if it does not work for me, i will let everyone know if it works!

I can confirm, the touch pro 2 screen does NOT work in the 7 pro, it is almost identical but the conector is at most 1mm wider than the 7 pro but its enough to stop if fitting into the socket
Back to the drawing board for me i guess.

not sure if you still need an LCD, or maybe you got a new phone by now. I found this if your still interested in getting it up and going again.

not been on for a few days, thankyou for the link its still there and in europe!
I bought another 7 pro handset as i could not wait any longer, i had been forced back to my old Touch pro (raphael) and although not a bad phone and running a custom 6.5.3 rom , it just cant cope on the web anymore as all the standards have changed and nobody is supporting windows mobile anymore.
Its a shame cos windows mobile is by far a better operating system than windows phone, updated and running on better hardware it would have rocked.
even though i bought a new handset ive always intended on fixing the other one when i get the chance and have put a bid on that screen to remove the buy it now.
Fingers crossed that it dont go up in price, my wife will kill me if spend much more on these phones lol
once its fixed its going to go in its box and live in a safe place till ive worn out this new one, dont think i wll sell it, thanks for your help, you get a thanks meter point for this :good:
Steve.

You are welcome I was a little worried you might not get to the link fast enough but thankfully you did! I seen that and figured its a steal considering the lcd is nearly that price alone, plus all the work needed to change it. Good luck I hope you win it

Thanks geeze

as long as you get the right screen, theres no reason why you cant do it yourself, just go slow, very slow, read tutorials and be very carefull of all cables and boards inside. if it its the glass digitizer that is broken and not the whole display, be very very carefull when removing it from the lcd as theres a big chance of breaking the lcd as its removed, heat to relax the glue is your friend! if the glass is shatterd, removing the glass bit by bit instead of trying to remove it all at once may proove easyer and less risky on the lcd.
Good luck, steve.

[Q] busted digitizer (i think)

Hi,
About 3 weeks ago my nexus 5 got wet, I dried it quickly and it seems to be ok, except not touch.
The screen is ok Wi-Fi 3g all is working.
I could not find anywhere how to replace only the digitizer (adding the screen is quite expensive).
Anyone had any experience with this?
Thanks.

You can only replace the whole screen (digitizer included), not seperately. Look on YouTube for iFixit video`s for how to replace it if you want to do it yourself.

Hi, Thanks for your answer.
That part i know, however it's quite expensive and i have a new device so i'm in no hurry.
Do you think that in the future there will be a seperate digitizer?

Don`t think so, it will stay a one part component.

ok, thanks.

Reviving my (cracked) Nexus 4

Hi there, could anyone tell me based on experience, a really good LCD Screen + digitizer for me to buy? I can buy from ebay.in or ebay.com but there are hardly any ratings at all. If anyone has bought one, could you please tell me about the quality, link and if so, any defects? I would much appreciate it, thanks. Basically my screen is cracked an unresponsive, so i'm guessing I need LCD+Digi.

Hi, less than a month ago my screen also cracked, so I had to buy a new screen. Before buying it, I unmounted the phone and I had one more problem: the battery was COMPLETELY glued to the screen and I wasn't able to take it out. So finally I bought the screen and a new battery from eBay.
I bought this screen: ebay.com/itm/181445812771. I'm completely sure that the screen is the original one. I compared it with my cracked screen and they were exactly the same, except for the date printed in each screen, and it has a good quality, just as the screen that I had in my phone. BUT it was clearly used: the earpiece was a bit dirty and it had some glue on the back, probably from another battery. But I'm happy with the screen, actually, I prefer a used but original screen to a new but poor quality screen. Maybe they take this screen from a phone with a damaged motherboard or something like that. The screen doesn't have any scratch.
I wasn't so lucky with the battery. It was clearly a fake, so I returned it and bought another one from spareslg.com. I don't know if this battery is original or not, because there are some differencies between this one and the battery that I used before. Maybe this one has a bit better battery life, but I'm not sure, because now I'm using another ROM (based on 6.0 )
FYI, the non-original screens usually have problems with the proximity sensor and the GPS, so be careful with that. Good luck with the screen change! :good:
