How to Figure out if touchscreen or LCD or both are broken? - JASJAR, XDA Exec, MDA Pro ROM Development

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)

cracked internal screen

Hi i have got HTC diamond and i must've sat on it or something, but i have a few large cracks on the internal screen. Touch works fine i mean, everything is in working order, its jsut i have a massive cracks from one side to the other. I'm having trouble finding the right screen because there is the lcd panel with the htc logo and then theres another with just the screen. I want to replace it myself because can't be bothered going through the whole sending the phone off phase. If someone can redirect me to a plae i could get a screen for a reasonable price, that would be great.
Let it go... I'm actually having the same problem and there is one thing you need to know : you need to sold a connector from the LCD screen to the Touchscreen, it's not a connector that you can plug easily.. (((
I just bought a LCD screen and a touchscreen on eBay, but without this sold, it won't work as I would..
I have solder and the kit and if i can find a tutorial somehwere i'm sure it can't be that hard. You said you found it on ebay, do you have a name or maybe a link? how much did you pay? =-s

Cracked Screen on my Touch Pro

I dropped my touch pro and cracked the screen in a few places. I think it works normally except for the screen, as it receives calls fine...
A new phone isn't in my budget right now. Does anyone know of a good place (hopefully in DC, MD or VA) that will supply or install a replacement touch screen?
(btw, no recent threads came up when I searched.)
Ebay!
Just looked, $30 including postage for a screen & digitiser if you are able to do it yourself.
How hard is it to replace a screen if it has surface damage? Is there anywhere i could find a walkthrough or help?
Shame man, its a tragedy of what happened to your phone...
Luckily its not too bad, and you may just be able to fix it. You can download the service manual for the phone here: http://htcwinmobile.blogspot.com/2009/03/htc-raphaeltouch-pro-service-manual.html
Just a note though, make sure you DO USE tweezers or something to get the speaker wires out of the way before snapping the enclosure back into position... I had to reopen the phone again, after powering it, to rejoin one of the little wires thats like a tenth of a millimeter thick DO NOT IGNORE ANYTHING THEY TELL YOU IN THE MANUAL. Oh, and what works well for the "plastic removal tool" is a cut out piece of plastic ice cream container. AGIAN, do not ignore anything in there... You are voiding the warranty permanently when you do it yourself (which you unfortunately have to).
Anyways, good luck!
I drop my phone also, but the screen didn't actually cracked! but I do have is problems with the screen in other ways! Sometimes I get a black screen when I turn on the phone and sometimes not, but when the screen turns on, it flickers a lot and have lines thru it. What suprises me is that sometimes I get perfect images on the screen (Which makes me think that the screen it's not damaged).
Any suggestion would be apreciated. Thanks!
3 days and still no answer from anyone! I would like someone to throw me ligth on this issue. I'm waiting for this to know exactly what I need to buy, before I start assuming things.
Thanks in advance!

Sounds like the LCD connector may have come unseated. You could open up the phone and make sure all connectors are firmly seated if you feel confident in your abilities.

Thanks for the advice! I was thinking on that also and wanted to take my chances opening the phone (oh god!).
BTW, I saw the $30 LCD Screen+Digitizer combo on ebay that Beeble referred to, but I'm not sure if it fits on the fuze (my model). What have come to my mind it's to buy also the front camera of the phone (like a thread on the kaiser) to mod the cell, in case I need to buy the screen+digitizer. I've search all threads about this issue but nobody has done it because it was too expensive for the result; I believe with this price it's worth it right now!
solved

I used Diamod (!) LCD and Touch Pro digitiser. Works perfect.
Much more cheaper
If your screen works fine sometimes, you most likely don't need to replace it. there's probably just a loose connection somewhere. If you really want to replace it though, there's an ebay seller with a really good deal. $20 for the screen and digitizer already glued into a new front body piece: http://cgi.ebay.com/OEM-HTC-FUZE-LC...wItemQQptZPDA_Accessories?hash=item3ef8817bf6 That one's for the fuze, but I think the seller has other models too. I'd definitely get the LCD and digitizer together or else you might end up like I did on my first attempt: http://forum.xda-developers.com/showthread.php?t=584050

WOW! What a long way to get to the screen. Good luck for everyone who tries to dismount and mount the Raphael.

Thanks for the advise maxh,
I just wanted to let you know that a miracle just happened! my cellphone started to work just fine without even opening the phone! it has more than a week on this situation so I believe that it's exactly what you stated (the LCD conector became unseated or loose). Since it's still working, I have no need to open it! so I'll just wait until it becomes defective again and at that point just open it and tight up the LCD connector!
Anyway, I would love if somebody could make the mod that I was refereing to before (changing the screen of the fuze by the touch pro one) and see if it's possible to attach the front camera on the fuze.
Once again, thanks everybody for your opinions.
I got my new display+ digitizer on Ebay (65$) and replaced it, using the russian link mentioned above ( follow the exact procedure) , it took me 2 hours to do it, and after lot of patience it worked! My problem was the digitizer never worked fine, and after replaced it it worked like never before. If You are not familiar with repairs, it will be a mistake and waste of money to buy a display without digitizer. NOW, I have a small problem, my display has a NEW color, it's like color temp is WARM for this display, and COLD for my old display, AND COLOR level is lower, and the result is display without vivid colors, black like gray. Is there any way to change the DISPLAY color settings?

Chances that an LCD + digitizer will fix this?

A coworker I started working with a few months ago told me about the much-better Sensation he had before his MyTouch 3G. It seems that he still had it, but stopped using it "because the screen cracked." I correctly surmised that it was a simple and cheap to replace touch screen digitizer and described to him that it was "just the glass cover" and that it was "cheap to replace." I have done many such repairs on other phones and gadgets.
He then told me that he had continued to use it until the LCD went blank. There is no reason to think that the LCD inside suddenly cracked, but I can only assume that it also sustained some kind of damage and now also requires replacement. Knowing that the LCD isn't cracked, what are the chances that a replacement LCD + digitizer will restore the phone? I'm concerned because we've already purchased a kit for $65.
Nobody can tell you that off the internet. If we do, that would be pure guess, just as accurate as you would have guessed.

Well, someone could have had the exact same problem and already tried it. I ran into people with the same problem already. I'm just looking for more because some, no doubt, have tried it and others may have an alternate explanation. Reasonable.
there is a good chance that will fix the problem. but since the LCD was working for a while until it blank out, it is possible the problem might be with the circuit board. only way to know is to try it out.

The LCD could go blank for several reasons. Faulty LCD, loose cable, faulty board etc. etc. Even if someone had the same problem, the reason for it could be completely different, thefore this wont help you at all except for giving you hope. If this is what you need, then i would say "yes, the change of lcd & digitizer should fix the problem" but you never can be sure unless you try When you start the phone, do you hear the startup sound? This could at least indicate that the phone isnt completely faulty.

The plus side is that you can't make it worse. So you've got nothing to lose by trying to repair it, other than the few bucks for the parts.
Well, I took it apart to re-seat all the cables and it's still blank. Reading online, I see that a lot of dropped Sensations/Pyramids develop a loose/broken SMT capacitor component near the headphone jack, but I'm not registered on any of the forums I see it discussed on and I can't see the pics. They describe a slightly different problem anyway (screen goes blank after standby). I needed sleep, so I put it all back together and I'll check that out when the parts get here. My hunch is that the LCD panel is fine and that I'll have an extra, assuming the capacitor problem is fixable. I've done some delicate soldering work before but I can't really say that I'm good at it! I didn't see any loose SMT components rattling around so I hope it didn't fall completely out somewhere.

Thanks but it's almost $70 for the parts.
Works great! Well, it had the touchscreen sensitivity issue pretty badly but the T-Mobile OTA update fixed that. Transferring all the adhesive bits from one screen to another was down-right frustrating, but I pulled it off and I only see a single spec of dust inside. The dude will be thrilled. I broke the earhook on my Looxcie so I did not make a video but it was full of me tearing and ripping the things anyway and not a good example of how it should be done!
FWIW, there was no way to remove the old screen without denting up the backing plate and prying the heck out of it to free it from multiple adhesives and glues, so I would not have had two good LCDs after testing the replacement even if there was nothing wrong with the original. Good thing it was the LCD at fault! I didn't have to drill anything like the glass replacement video I watched instructed me to do. They didn't realize that the LCD removal allows the flex PCB through just fine. I forgot to thread it back through before seating the replacement LCD in the adhesives and tape left-overs but it flexed enough to allow it through without removing, which was quite a relief after seeing how the original fared after being removed.

Inspire screen crack

I've had my inspire since May, and cracked the screen in June. Everything has worked fine until last week when I noticed part of the screen aren't responding to my input anymore, and neither are the soft keys. The picture itself fine though. So my question is, I were to buy something like this:
http://www.amazon.com/HTC-Inspire-S...VJ4G/ref=sr_1_1?ie=UTF8&qid=1335159461&sr=8-1
Would that fix all my problems? Does something like that include the glass?
Yeah if its not responding to touch you will need to replace your touch digitizer. I believe you may just need that one part but seems a little too cheap.
Maybe someone who has experience changing these can chime in..
You will need only the digitizer, I believe. Just shop around for a shop that will repair it for you. Much easier for you in the end. Just looked it up on craigs list, shouldn't be more the $50.

digitizer or LCD screen.

So my photon Q is rather old. Shocking I'm sure. Recently the screen has started behaving very oddly. Flickers, sensitivity is weird, blacks out etc..
I thought perhaps flex ribbon due to keyboard sliding and closing but now I think may be digitizer or the lcd. I"m leaning towards digitizer becasue when it does work it looks perfectly clear. But there will be the one time i push the power to check if I have anything and nothing happens. Reset it and can see the screen wants to do something but can't decide what. Reset over and over and eventually boots up fine.
Digitizer?
Thanks for any info.
Anybody able to chime in
Flickering screen can't have anything to do with the digitizer. The digitizer is just there for input.
It could be that the connector is a bit loose on the mainboard. The way the Photon is designed I wouldn't think it's the ribbon. I could be, but very unlikely. Anyway it's worth looking into the connectors and just to be sure the ribbon as well. But that would take a full dismantle. The connector is just 5 minutes work.
Next time try booting into recovery. If that goes well (and regular boot not) i'm pretty sure it's a hardware problem (GPU).

When boot in any mode Ican't see anything.. A fading circle of grey lines runs vertically down the front. Sometimes after many reboots it fixes itself though. Good to know not digitizer. So take apart and check ribbon and maybe replace LCD likely?
I wonder if it is possible to simply replace the LCD if it's defective or if you have to replace the whole LCD-digitizer-speaker-etc set (which is expensive).

I ordered a replacement lcd screen so will find out. I also ordered the digitizer and flex cable.
So i'm thinking it may be more hardware involved than screen inolved. When it does work everything is usable and it works fine. This is only about 10% of the time at this point. Otherwise it boots up to show some vertical lines traveling down the middle of the screen but only in a circle in the middle of the screen that fades as it gets close to the edges. I'll try taking apart tomorrow night to see if ribbon and what not looks ok. But so far i've invested about $70 into parts and i'm thinkin about just snagging an S5 for $100. I will miss the keyboard though although I can hope that like the s3 and s4, the s5 will get a keyboard attachment. Thoughts?
If I remember correctly the LCD comes with the ribbon and camera connected. The digitizer is connected via a ribbon to a board in the top of the front panel. You could try to disable the pin. When the phone doesn't seem to work, reboot and try calling yourself. If it rings, there's something wrong with the screen and not the phone.
If there was something seriously wrong with the phone, it wouldn't boot. But that's just me guessing/assuming.
My daughter's Photon has had a digitzer replacement twice. And it looks like it's been used to play football. But that one still rocks. No quirks or any strange behavior for that matter.
What I'm trying to say is that the Photon is a decent piece of hardware. A family of four, we all have a Photon. Three of which have had their digitizer replaced and one an LCD (scratched it when replacing digitizer).
I swapped my Razr HD for an Z2. It was time for a new corporate phone. So that, and the camera, is the reason why I went for a Z2. My options were 930/G3/S5/Z2. S5 is not my cup of tea. The G3 has no ruggedness whatsoever. The 930, apart from WP maybe I should have went for it.
So it came down to the Z2. To be honest I'm looking to trade it when the Z3 compact arrives. We'll see.
@Loader009
Digitizer is a part, board for speaker is a part, the speaker itself is a part (adhesive, watch out, btw 100% the same as Droid4), and the LCD is a part on it's own.
Going to open up my phone tonight after work. I was bored and was just playing with the keyboard sliding it open and closed a bunch and now the screen looks perfectly clear.. although sometimes it will still black out and I have to reboot it a few times to get it back. I feel its more a connection inside like you stated earlier. I love my Photon and really don't want to have to get a non slider phone. New phone's are so friggin huge lol.
The good thing is, the PQ has gotten pretty cheap, so you might want to get a used one at ebay if the part to replace is too expensive.
flickering screen (backlight) is not lcd problem.
for 70% is it problem on mainboard - backlight ic. This problem is caused by using unoriginal charger.
and 30% flex problem
I had my screen become un-responsive etc, it was due to a crack in the ribbon. Swapped it out & all ok.
Easier to swap the whole screen assy than to change the ribbon, but depends on what spares you have/can get.
You'd need to have a good look at the ribbon for any damage.
