Picked up this phone from CL. The person was claiming that part of the screen is not responding to touch.
I have seen it when I picked it up, but I thought that I will deal with it when I get home.
I was keep playing with the phone almost everything it's working on it except the volume buttons and that horizontal line where the #456 is on the dial pad.
I have removed the battery and noticed that the white sticker it was pink, water damage.
Now I don't know what could be the damage here? There is a shadow across the screen also, but it's not a crack.
I have seen this before on a digital camera, it was the aluminum sheet metal under the LCD, had a smudge across on that aluminum finish too.
Couldn't remove it though. Replaced the screen on the camera and it was as new.
Not sure what could be the problem with the phone?
Should I replace the digitizer, since the LCD shows everything correctly? It could be something shorted internally? I have the phone apart, but I don't see anything wrong. Cleaned all the contact with electronic cleaner, no change.
Any help would be appreciated.
Please post all questions in the Q & A section. Thanks! Thread moved.

I think I would replace the LCD and digitizer as a unit. The slightly higher cost would be easier to accept than having to do it more than once, which would probably end up costing more. Either way is a gamble, though, because that might not be the issue.
Volume buttons are notorious on this phone. I have not known or read about someone fixing them. You can get around the problem for the most part by using software to control the volume, using roms that will restart to recovery or boot loader, and the occasional use of ADB commands, but some bootloop situations require the hardware to work.
Good luck with your project and let us know how it works out.
Not just a pretty Pickle.
I'm thinking of buying the whole LCD as a unit, but that is why I'm asking that maybe somebody could tell me if it's the LCD or other hardware.
The volume button it's together with the upper camera board and I guess it has to be replaced together.

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.
Hi there. I have a pebble blue16gb S3 that's currently on the fritz. Some people are recommending a jtag service to force a stock rom back onto my s3. I've got others that are telling me my emmc chip is probably bad and that a jtag probably won't help my issue at all. Anyway, I've been cruising craigslist and I found a 16gb pebble blue s3 that has a cracked screen. In the pictures I was sent the crack is right down the middle. The guy selling it says the LCD display wont show up at all, but in some pictures the back button and the other button light up as well as the blue notification light on top were working in the picture. He's selling the device for $90. I checked the IMEI he gave me on swappa.com/ESN and its said its ready for activation. I asked the craigslist seller how the device was damaged and he said he got into a car accident going 60mph and he was hit by a drunk driver and the phone hit the dash. I have a buddy of mine who is willing to take the motherboard from this phone and switch it out with my phone, but he expressed concern that the fact the LCD won't display anything and he thinks the motherboard may have suffered some kind of damage in the crash causing the device not to display. He also noted that he has seen phones with cracks all over and the lcd still displays something. Can anyone shed some light as to how much impact a Verizon SIII motherboard can absorb and if its possible for the screen to totally not work, but the board itself be fine? Thank you very much!
Im not sure if this was the right thread to post this question either, but I hope it is. Thanks!
Also just wondering, is the notification light at the top and the lighted back button and the function button by home at the bottom run through the same connection that controls the display?

I repair these devices and I'll say that you should just stay away from an S3 with a blacked out LCD. The repair for the LCD is about $300. Just a cracked glass may run you anywhere from $80-$150 for repair. The motherboard could be damaged, but there is really no way to tell unless the screen is on. I doubt it would be broken, though... I would look at it to see if the metal frame around the screen were bent or warped. If not, I doubt it would be. If the soft keys light up, you should also hear the volume turn up.... this checks to see if the speaker works.
But with a busted LCD... too much cost to fix that and not worth it. May as well buy a new one.

So should I just pass on this craigslist phone? All I wanted was the board from it and switch it out with my motherboard that is on the fritz.
Hello,
Touch screen glass was broken, due to my phone fallen on the ground. The LCD was still working perfectly so i've ordered a new genuine digitizer for my HTC Z710E.
After replacing it my GSM does nothing . When charging i see the charging light lighting up in red or either green when full, but besides that i won't do anything. I disassemblied the phone again twice, reconnect all the connectors and still nothing. Sometimes my phone vibrates and sometimes when i push the power button the charging light disappears but that are the only signs of living.
Is this a common failure after replacing the digitizer? Did i overlook something?
Hopefully you guys can help me out.
Thanks in advance!
If the LCD ribbon cable is, in fact, getting a good connection then I would probably lean towards the lcd itself having been damaged during the install. Due to the construction of the sensation, it can be difficult removing the lcd without damaging it even for an experienced tech like myself.
What I would suggest would be to go ahead and order a new lcd. This would also be a good time to double check that the part number on the new digitizer's ribbon cable matches that of the broken digitizer you removed, as the incorrect part will lag when the screen is turned on at best and will not work at all at worst. As far as I know, the sensation and kindle fire are the only devices like this where you will have slightly different parts even within the same model and region.

Hmm i already thought so . I did it really really careful, but despite that it broke.
Time for getting another phone. Don't have much money now, but i shall see what's for sale
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.

I picked up a used LG G2 from Ebay. The phone is in somewhat great shape and is functional except for the top portion of the digitizer. About an inch, give or take, at the top is unresponsive to touch. I just wanted some input on how common digitizer damage is on this phone. I know most phones these days are very delicate and the digitizers and LCD's can be damaged quite easily. There is a good knick at the top of the phone so I am guessing it had been dropped at one point.
I paid $150 for the phone and I can pick up the LCD, digitizer, and mid body assembly for $65 on Ebay. Just have to slap the internals in the new mid body, throw the back cover on, and done. Phone is good as new. But I don't want to make that investment IF by some chance the problem isn't the digitizer but rather something wonky with the main board. The more input the better. Thanks guys.
It's the digitizer, I sent mine in for the same thing.. Dunno how much it cost tho cause I had warranty. Hope it goes well replacing it

Thanks MaestriFC. While I was waiting on a response for this, I noticed the phone decide to go quirky on me. I looked it up and found on XDA this is a common problem? Phantom touches, etc.? I seen a couple people say it is still the LCD and digitizer causing these issues and replacing them fixed it.
Well I dropped my phone on tile with no case so I don't think it's a common issue (unless everyone is dropping them) but from what I read the digitizer was loose so you would have to open the phone and connect it, or get it serviced, I don't remember getting Phantom touches though..

Yeah. I read on another forum about it and found links to these problems here on XDA. Apparently, this phone going spaztic is a very common thing. Which still hasn't been traced down to any one specific thing. Most are having LG replace their phones just to get another one doing the very same things. I am going to order the new LCD and digitizer though. Hopefully it fixes the issues. Maybe LG got a batch of faulty digitizers or something....lol...here's to hoping.
Make sure you do your research on replacing haha wouldn't want anything else messed up... In my opinion you should just try to connect it properly and see if that works, that's if you're going to open it anyways of course, could save some money.. Good luck :thumbup:

I tried that. I opened it up, and from what I could tell the phone has never been opened. The screws were tight and came out with some black stuff on the threads. That's USUALLY a sign the phone has never been opened. I reseated the top and bottom connectors for the digitizer. The one on top and the one on bottom, I didn't reseat the other one at the bottom though. But I figured that one was for the bottom portion of the digitizer anyway. Which is working. When the phone starts up, every now and again, the "LG" screen will just flicker then boot up. But most times the "LG" screen shows as normal when booting up.
I did also find out from normal calling that the microphone for speaker phone isn't working properly. Normal headset works just fine. But when I switch it to speaker phone people can barely hear me. But that microphone costs like 8 bucks to change so no big deal. I have checked out many youtube vids on fixing this phone. It can be challenging to have to remove everything but I have found just buying the LCD and digitizer already mounted to a new mid body is the easiest way to go.
So the repeating the digitizer didn't work? I would buy the two together as it would be a lot easier than separating the two.. Might just be you had a faulty one after all

I haven't replaced it yet MaestriFC. I will report back in a couple weeks though when I do get the new screen in and get it all replaced. What didn't work was opening her up and re seating the cables. I thought maybe something could have been or come loose but that wasn't the case.
Just an update guys. I got the whole LCD and Digitizer replaced last night. It's only been a few hours but so far everything is great. No more glitching out. As a matter of fact, I had no choice but power the phone down last week. That's how bad the glitching out got. My phone was totally unusable. But now with the new screen, it's working great. If it stays working great then we can assume the problems with this phone are the cause of bad digitizers.
