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.

[Q] Anyone got a MT4GS (may be bricked) for sale?

Hi!
I was heartbroken when my MT4GS broke recently. I need a replacement screen assembly for it. I've been looking on ebay, but I only see phones with broken screens or individual service parts. I have a working motherboard but, I need the entire screen assembly replaced.
If anyone has a bricked (or fully working) MT4GS with an otherwise nice looking (and working) screen that's just lying around collecting dust that they would be willing to sell cheap, I would be very happy. I should mention I live in Europe. I'll cover any fees, obviously.
Alternatively, does anyone know of a worthy successor (GSM Android QWERTY slider)?
Thanks.

You should try ebay. there are all sorts of spare parts for this phone and you can get just the part you need without having to buy an entire phone. At least that way you will spend less and not end up with parts you do not need.

very true, this happens to be one of the more pain in the ass phones to fix but it still isnt all to bad. a new digitizer (and very likely will need a new lcd as near impossible to separate) will be in the range of 50$ if you need more than this other parts arent too expensive and not terrible to replace.
as a successor... there really isnt one, closet upgrade with a qwerty is the galaxy relay, others may disagree but between the vision and the doubleshot i am hard pressed to find a true high quality qwerty phone

I've never had any trouble getting my LCD out. Though my phone had been opened before, so the sticky wasn't as well stuck to the backside of the LCD. You can use a bit of hairdryer heat to loosen the adhesive.
Now digitizers... Those I seem to burn through.

Well, I suspected that the cable connecting the screen to the motherboard had become damaged, due to the touch function and screen dying when sliding the phone open. I did order a spare part on ebay but in trying to seperate it from the LCD, I ended up making it worse. I did use a hairdryer to warm up the adhesive, alas, it seems I wasn't careful enough. The end result is that I now have a "bottom" part (keyboard, motherboard, etc.) which is (presumably) still undamaged, but I need an entirely new screen assembly.

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.

Display replacement and troubles

First, sorry my english. If anything is incomprehensible, ask me.
Not long ago I dropped the device and fell to a gravel, not defended by the ?Gorilla Glass. It became a spider web. Essentially, the device was working, sensing the touch, and the display was relatively intact in just one spot a little pressed. I ordered a replacement part from here, because the glass also fell and because it couldn't stay. I chose express delivery, stuff arrived within 1 week. I have made it difficult to disassemble the device because the back is glued together. It didn't want to come down, I tried all kinds of plastic tools they had given and what they were, but the glue was so strong that they all broke (I'll be curious to know how to put them together). I had to use a paper cutter, because it is sharp and goes into the gap. Unfortunately, the breakdown at the corner is slightly visible, but it must be as much trouble. Luckily the adhesive came out of the battery. (I will also have to order it from somewhere for rebuilding ). The main panel also came out of the house nicely. If we are already here, I removed the unwanted heat conductor paste and replaced it with quality Grizzly.
The display did not want to come out, it glued to the frame so strongly that it was impossible to remove it. I managed to do it in pieces, and I licked the remainder for half an hour. Worse, there is something new, no matter. Then I realized that the new one had no glue, and that the old one could not be removed because it was not an adhesive, but something like a very thin siloplast. I have injection needles and black silo, so I can make up. No loudspeaker lattice was added. I hope I can take the old one somehow to stay together. And here comes the black soup:
I plugged in the cable and turned the phone on (not screwed up with just a few screws to hold it). I have a picture, I started to calm down. Need to unlock it, but don't works, it don't feel my finger. Nowhere. If I remove the factory foil, either. I looked at the stuff in more detail. The photo already shows that something is wrong in the lower right corner of the display. The original has a large square-shaped Synaptics S3330 chip, the touch panel controller (like Mi 5). However, this is missing from the replacement device, with a much smaller IC of "S20A X705E24". I have no idea what it is, but it is also suspicious that a ribbon cable goes below the original and there is nothing there. But on the site of the seller there is also the ribbon cable in the pictures and it is highlighted as "Multi fingers touch chip". This may be some great big scam. However, if it have a Touch controller IC and something that is supposed to work in principle, then the Synaptics driver (kernel module) is loaded on Android. I suspect that then this IC should get the kernel module somewhere and should be loaded to work with a rooted device. But I also thought that I would try some other rom (AOSP, LineageOS) and see if it would go with it, but chances are that Recovery would not work with a USB mouse + keyboard. Maybe there are different hardware versions of Chinese and global versions? Because it is possible that Chinese (or eu) would work.
I wrote to the seller that the stuff wasn't working, he said I would remove the connectors with an alcoholic cloth (of course he didn't help). Until then, the time was up to 15 days, so I can't start a dispute. He asked me how he could help, I wrote to him that I didn't know but I needed another display in this device. I wrote to him that he might be able to return my money or send another display. He said that if I stood at 75% of the cost then he would send a new one. At first I would have gone into it, but now that I've examined this and it turned out, I wrote it and sent the picture as well. I don't expect anything good.
I found another seller that is already fitted with the frame (minimal more expensive), maybe there shouldn't be any fun with gluing, I could do better if this is not solved this way.
What do you think about this whole thing?

That gold one is dor mix 2,and that black one is for mi mix 2s, right?
