HTC Sensation death after Digitizer replacement

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

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.

No display on nexus 5 even after screen change

Recently, I purchased a Nexus 5 from a friend. The screen was completely shattered and nothing would appear on the display, but my computer was able to recognize the device. This morning I replaced the screen with a new one, however, there is still nothing appearing on the display even though the computer recognizes it and there is still life left inside of it.
Is there anything I am missing? I rechecked that everything is plugged in correctly several times and still nothing. I was thinking of replacing the flex cable, but I am low on funds so I don't want to waste money if its not going to work.
Attached, are photo's of the device.
Any help is greatly appreciated.

did you replace just the screen or the whole Assembly with the lcd and digitzer?

Yes, the entire assembly has been replaced which includes the LCD and digitizer.
Once again, I'm thinking its the flex cable as bad flex cables I've had with other phones have affected the functionality of the device.

It was not.
In a nutshell, my original question was basically 'could there be another problem with the Nexus 5 that I am unaware of?' which was not answered.
The second poster simply asked me if I replaced the LCD and digitizer assembly in its entirety.
The third poster is me posting my suspicious about which piece of hardware is causing the trouble.

Oh sorry you said flex cable. I was on my app. My apologies. Honestly it could be the flex cable. I replaced the screen in my Droid 3 and it didn't work because the flex cable was damaged.

Based on your photos it looks like what you replaced should have bean sufficient but of course with electrical components who knows... I wouldn't rule out a dead replacement display either. I'm in the middle of a similar situation, returning my replacement display today and trying another.

Could be a number of things with that physical damage, not just the screen

So you were able to get a display after you changed the flex cable?
The odd thing though is that I'm still able to charge the phone...the flex cable also holds the usb port.
Anyway, I've ordered a new one so we'll see what happens.

If anyone was wondering the screen still does not work with the new flex cable. I'm assuming its a motherboard issue and am just going to sell it on eBay.
Before than, any other suggestions would be appreciated.

Just ask your friend for a refund

I bought it from him for a very cheap price ($30US). Even with it broken, I can still get more for it by selling it on eBay than I can by getting my money back.

Try to make preassure on the wide connector on the motherboard. If display backlights or displays temporarily it's micro distached pins between connector and motherboard. Heat Air is the easy solution! In my case I used hot air heatgun 350°C and 10sec on row near edge of the board. The solder melts and at that time PUT slight PREASSURE down to the connector for few seconds! It makes the legs got proper contact to the pads on the board. Solves problems with Mic and Loudspeaker too becouse it relay on this wide connector.
Good luck Tomáš

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.

Question Considering buying the Asus ROG Phone 5S, have some questions.

So the cat knocked my OP7P off the bedside table while it was charging which has screwed up the charging port (have confirmed it isn't the cable) and now it will barely charge, so I'm in need of a new phone.
I'm liking that the Asus ROG Phone 5/5S has a 144 Hz screen and a huge battery. But:
With the resolution, is the 1080 × 2448 ok? Do you see the pixels at all? Like is it completely smooth?
Also, with the software, does when you enable invert colours mode and blue light filter mode (might be called night mode, alternatively) at the same time (try it on a white background with black text) does the blue light filter mode apply over the invert colours mode (thus making the text red) or does it apply under the invert colours mode (thus making text appear blue), or does invert colours ignore the blue light filter mode (working like it is disabled)?
And how is the battery? What is screen on time like when for example just web browsing or watching YouTube in 144 Hz mode? What is the SoT like when it is on 60 Hz mode. (I ask because my OP7P has crappy SoT when in 120 Hz mode.)
And finally, how is Asus software 2-3 years out from release. I like to keep my phones for about 2 years, how do you think the software support will be 2 years from now (given that the 5 is now almost a year old)? Regarding smoothness and Android version updates in particular.
Edit: does the 5S have a Tencent version? I haven't been able to find any info saying there is, and the site I'll be buying from offers the Tencent version of other phones but not this one.
Thank you!

the oneplus 7 pro is still a great phone by today's standards, why dont you try getting the port repaired? it wont be too expensive.
i dont own an rog phone 5s, but from my experience with oth 1080p and 1440p phone screens, you cant really tell the difference - heck you cant even see the pixels too clearly on a 720p screen. i thought my old phone was 1080p when comparing it with my 1080p phone, turns out mine was 720p the entire time! So yeah, the screen should be just fine.
One thing i will warn you about is that "gaming phones" usually dont have the best cameras, for example, you wont be getting OIS in the rog 5s, whereas your oneplus 7 pro does have that. gamging phones are more about maximising performance, whereas normal flagships are all-rounders. no doubt tho, the rog 5s will surely be faster than your 7 pro (mainly in games), as it has the 888+ chipset

There are no authorised service centres available in my country, unfortunately, and if I'm going to have to back up and restore data I want to do it to a new phone, not the same phone (this is because I don't like to send my phone in to places that require your lock code, which all the places in my country ask for when doing a repair, so I wipe the phone before I send it in).
Also, I didn't want to wait on the parts which could take like 1-2 months based on the estimates I'm getting from eBay (no parts shops for OnePlus in my country) like at the rate that this port is getting worse, I'll need a new phone before the parts arrive
I could try to repair it myself (I worked in a phone repair shop once), like I think I could get the back off without damaging it I suppose I have nothing to lose other than the back glass lol
And, wow, I didn't realise it didn't have OIS. That sucks big time. Considering the OP10 (when it's out) instead now lol
Anyway, you're right, I'll try to repair it first, then if that fails then I'll get a new phone

I don't think they'd need your lock code to change a charging port tho, all they have to do is test if it works after the repair

If you want to sell the oneplus let me know LOL
At a HUGE discount of course

Yeah, true. Though what plays on my mind was that we were authorised repairers for a few manufacturers, and certain manufacturers (can't remember which ones) required a freaking software reset to complete simple repairs like that. Like hwhat. I suppose I could have asked OnePlus, but I also don't have a spare phone to use while it's sent away.
Either way, I bought the part (charging port+flex and rear adhesive) and I'm gonna try the repair lol.

if the charging port is attached to the flex, then it shouldnt be too tough. be sure to look for a disassembly guide for your phone, so that you dont damage it. use plenty of heat (but not too much) and be careful when prying on the back of the phone as replacing the glass will cost you, and its near impossible to reapply broken glass after removing it, as if you break it during removal it will be completely destroyed by the time you get it off your phone. cheap chinese picks break easily, so if your buying those then buy a couple, and make sure to get the triangular ones, as they are the most effective. its also worth it to use a suction cup to pull the glass back, as it prevents you from possibly putting uneven pressure or damaging the back glass.

Thanks heaps for the tips! Much appreciated!
Would a hair dryer be enough to heat the rear of the phone to a serviceable temperature?

it should be possible, although it would be both tricky and risky. depends on how strong the adhesive is i guess
