Black Spot on screen - HTC Amaze 4G

I just got the screen and digitizer replaced on my HTC Amaze, it was a one piece replacement. Now, i can use the phone normally and the screen doesnt jump around like it did before, so i guess there was a bad digitizer..
However, now there is a large black spot in the center of the screen, and im not sure what it is....
It seems that the touch interface in that area is still responsive, and it tries to blend into the color scheme of the phone, but when the screen is off or black, it is quite visible...
There is no plastic or screen protector on it, so its not a bubble from that. I did a factory reset, thinking for some reason it would help, but it didnt... And being that i just bought the screen new off ebay, i was not expecting this.
Any help would be great! Thanks

It looks like a busted LCD...

So my issue now is as follows (the phone wasnt mine, i just got it for cheap since it had bad digitizer so i bought it):
The old screen had a bad digitizer, and in the process of removing it, the glass is now cracked.
The new screen from ebay has a the black spot and is currently in the phone.
I called HTC, and it seems that my phone is under warranty. (I know, this should have been the first thing i did. Stupid Mistake!)
Question is, will HTC fix the screen (even though its not the original screen) ...?

Try doing a manufacture warranty exchange through t mobile. (That's if your with them). I did that with a sensation I got from a trade. Told them there was dust under the screen, they sent me a replacement. 5 sensations later, they sent me a amaze (Kept getting dust under screen with replacement).
Worth a try.

[Q] After an LCD replacement

A while back ago I received a G1 (Which was my favorite Android @ the time) with a broken digitizer. I was going to replace the digitizer shortly after having it unlocked. But I ran across a friend who bought an Aria off of Craigslist, who needed a T-mobile (Or unlocked) phone. So I traded my buddy my G1 for an Aria with a broken LCD. I ordered the LCD (Screwdrivers & such) off of ebay, and replaced the LCD shortly after. I didn't really have any problems doing so. But I've started to notice that it seems as if the screen / digitizer doesn't really fit down all the way. If you catch my drift. Like, Sometimes I can push the corner of the screen (Where the LED is) and it sets back down, but arises again. Would this be something that I did wrong, or maybe I need a new adhesive strip (so to say) to put back around the digitizer? Any suggestions would be highly appreciated.
_Edit_ The performance of the digitizer nor the LCD are affected. Its more so my personal preference to have it back in the right spot I guess you could say, for resale to upgrade. (Which is pretty consistent)
Same Issue
HI! I have the same issue with my Aria!
I noticed when I was replacing mine that the adhesive part you mentioned seemed "not so sticky anymore." When I take the back off and look at the corner that stick up slightly, there is no sticky at all there. I assume that's the problem. I just leave mine as is. But if there was a simple fix, I would love to know!
Hope
Actually, almost all arias do that (to some extent) after a couple of weeks. I noticed it shortly after I purchased mine. It's probably a design flaw, or just a bad design in my opinion.
The sticky tape must just break down overtime.
Just a theory...

Well. Bummer. It would make sense that it is a possible design flaw. Everything has something wrong with it. Oh well. Guess I'll just roll with it until I trade this off for something else. Thanks for the replies. Much appreciated.
I have carried my aria in my pocket, no case, for almost a year. No sign of separation from the base at any corner. I don't think separation is a normal condition from regular use. Maybe need new "stick down" stuff.

+1. Ive also never had any issues with the build quality of my Aria. Ive seen enough issues posted in the forums to know that there had to be certain batches of Arias that were just poorly made. This little thing has been through quite a bit (working on construction sites) and it still looks like the day I bought it with the exception of a scratch in the corner of the back cover (I do use a screen protector). Nothings loose, nothings worn out, nothings ever broke.

[Q] Motherboard replacement

A friend's wife dropped her vibrant into some water and powered it on before it was completely dry. Now the display is distorted with lines, occasional flickering, etc. The phone is usable sometimes (when you can see). The touch screen seems responsive, speaker works, front buttons work, and pretty much everything else I tested.
At first I suspected the display, and it might still be bad, but when I took it apart and cleaned it up there was a damaged part on the top board.
Not sure what it is, maybe a capacitor? Labeled, "2R2" on the top.
It's under the narrow portion of the metal cover. The cover that sets directly above it was scorched black.
Basically I'm wondering if it would be worthwhile or possible to replace this board, or even just the part. I'd prefer not to replace just the part since I'm terrible at soldering.
Is it even likely that this is the only culprit?
Any advice?
It is possible. See globaldirectparts.com/category-s/6611.htm for part names and google them for other places w/ cheaper prices. Sounds like lcd issue as well though.
checked there already. They don't have any of the major PCB parts listed. I googled the hell out of it looking for someone selling them(or even a part number) but the best I've found is people on ebay getting rid of "parts phones."
Craigslist or EBay for a broken phone is probably your best bet. See is you can get one that has a broken screen and no water damage. I'm guessing you don't have insurance? Or just seeing if you can do it cheaper.
Sent from my CM7 Powered Vibrant
They had insurance on the previous phone but they bought this one used and didn't call tmo to get insurance switched to it (if they even do that). So they've been paying for insurance that they can't use for the last several months.
I'm worried that the display may be bad as well and if I tell them to get one with a cracked screen they're going to be out the cost of the display as well.
Looks like that's going to be their only option aside from simply getting a new phone though.
Thanks for the replies

How to replace HTC Mozart glass / digitiser

I can't find any info on this, but it looks like it could be tricky to replace. I cracked my glass by dropping it onto stone, still works OK. You can pick up digitisers pretty cheap on ebay (£20 UK) but does anyone know how to replace? I read that they can be glued to the LCD?
Thanks
Google for the fixit website, if someone has done it there will be a tutorial, or you could follow the guide on here to upgrade your sd card....only because you have to take the phone fully apart. You need to check if the lcd is glued or like the iphone 4 resin. If they are a sealed unit you'd be better off getting the lcd/digitizer combo on ebay. trying to separate an lcd from the digitizer is asking for trouble imho.
I have ordered a digitiser, really hope the digitiser is not glued to the LCD, there is a big price difference. I'll let you know how I get on.
I bought a Mozart with wrecked digitizer and also want to repair it. The digitizer is on its way, so in a week i could tell you how difficult or maybe easy it is.
If you are faster, please post your experience.
I found this thread on xda.cn, and it seems that the lcd isnt glued on the digitizer, so lets hope so

EDIT: sorry cantpost links, so must change the x's to t's and w's
I have got my digitiser now, looks brand new. Just need to find the time to replace, might upgrade the SD card at the same time.
Done
I did this with Andy's guide to help: http://lifeinthefastlaneok.wordpres...-7-mozart-sd-card-memory-upgrade/#comment-225
I used this guide to replace my digitiser (the glass) which I smashed. The good news is that the digitiser is not stuck to the LCD at all. I just bought a grade A digitiser off ebay for £20 which was pretty much perfect - glass was perfect with a couple of small marks on the back case, but basically like new.
There were a couple of differences to this guide:
- Had to replace a speaker type thing at the top of the digitiser that was not present on the new one. Came off quite easily, just stuck in.
- Had to remove the USB port of the old case back (if you are replacing that too) but that was just a couple of screws
- You dont have to split the PCB off if doing this, you just take off the black clips to take it apart and then remove the orange ribbon cable, it is a little tricky to get the new one in but OK.
I now have a phone as good as new, I didn't replace the SD at the same time but probably will do at some point when I can stand loosing all my data.
Found time today to replace the digitizer. I also used Andy's videos for instruction. And it's really not that hard. Pretty easy for someones first mobile phone repair.
Well done, I would add for anyone else needing to do this, be very careful not to touch the inside of the digitiser or the LCD when you have it apart! Also have a glasses cloth handy for removing any dust particles just before you put it back together.
I do have one strange thing however - before I had intermittent issues where I could not slide the screen up when locked for 10 seconds or so. No I have a slightly different issue when unlocking - it doesn't always let me press on the right hand 3 numbers on the PIN screen! So it seems the unlocking issue some people have is due to a hardware issue. My digitiser was second hand so I might ask for a replacement, but I can change my pin so that it is not an issue.
My Mozart touch-screen hardly works at all plus my wife's Mozart has a cracked digitizer glass (still working fine).
So silly me I took the plunge and ordered three cheap replacement digitizers via eBay (from Hong Hong). They arrived today and all are s**t useless.
When I opened the box I smelt the rat when I spied the HTC logo on each was blanked out on the outside of the plastic zip-lock bags (with what looked like black felt pen), plus each glass has minor blemishes/scratches. Comparing each with the digitizers I removed from my and my wife's phones, they have a different design of ribbon cable conductor layout plus there are indications the plastic moulding isn't as well finished in a couple of places. Either these are factory rejects or knock-off copies. Lesson learnt :-(
Anyway, I now need to buy genuine HTC parts.
Any pointers toward reliable sources appreciated, thanks.

I have bought some off ebay. The problem is that these are almost always from returned Mozart's which may well have been returned due to non responsive screens, which seems to be a very common problem.
I have had 2 off the same chap now, one is OK but not perfect, the other one didnt work at all.
I would just keep returning them until you get one that works.
Sometimes you will find new combined digitiser/LCD's on ebay too, these would be a better bet but cost more.
Can someone who as changed a screen on this phone using Andys guide, please tell me how easy or hard it was, and how long does it take??
And would be grateful if someone could give me a link to the correct digitizer for this phone....
I am in the UK and have been qouted 50 pounds at a phone shop for the to supply and fit screen...
Did you see my post?

The most tricky thing for me was getting all the dust off the LCD and the digitsier, as soon as you get it apart things start sticking to it like crazy. Have a clean glasses cloth around.
It takes about an hour on your first go. The main thing is to get the orange ribbon cablle in fully, it can be tricky - you need to get a good grip on it (fold it a little) and push it home quite hard, otherwise you get it all back together and find it doesn't work.
I have had 2 dodgy screens off ebay, £50 sounds OK if it is a brand new original HTC screen.
Or just search for 'htc mozart digitiser' on ebayt there are loads.

Thank you for that. A close look at the ones I bought from china I'm sure now are removed from phones with faulty digitizers, then repackaged as new. One of the three had significant dust and dirt on the inside of the digitiser screen. I've requested a refund via PalPal disputes.
I've ordered some digitizers from ecell in the UK. I'm led to believe by them that these are genuine HTC factory supplied spares.

I just replaced my 4th screen (1 broke, 2 dodgy).
This one is perfect - as new condition and works perfectly, my last one was not responsive in some situations e.g. lock screen.
This is the one I got (UK)
http://www.ebay.co.uk/itm/130498971267?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Of course, your mileage may vary - some are probably good, some not. Replace it, if it doesn't work ask for another, etc.
My new digitizers arrived today from the uk. Horray they are genuine HTC spare parts properly packaged. The downside is they don't include the frame the glass sit in and is adhered to.
So I watched the official HTC Mozart disassembly video on youtube to see how to remove the existing digitizer glass from the frame - got it apart ok after heating the unit to soften the adhesives but it didn't come away entirely cleanly i.e some of the adhesive foam broke away and was left on the underside of the glass.
So... check on eBay and found sellers selling refurbished screen frames ready for a new glass to be attached.
Will update on progress once they arrive.

just ordered my digitiser today... wish me luck...lol

Well I am now buzzing... have just changed my screen at it works perfect.....
£50 they wanted at the shop...it cost me £13....
Just to let you know how easy this is to do........If I can do it, anyone can..
Did anyone find a reliable supply in the end? I just cracked my digitiser so looking to replace it...
--edit--
Also, how much have others paid? Don't want to be ripped off for some sub-standard part.
Hello everybody,
I m trying to replace the digitiser of a HTC Mozart too.
It is really easy to do, even the part where you have to take off the digitiser from the plastic frame.
But I have an issue, it is the second digitiser I am using ( from the same ebay shop ) and the digitiser is working inverted vertically! Really strange but it is like that.
As the mobile phone is started up, when I push on a left buton, it push on a right button ! On the key board, when I press on "P" it press on "A" ( i m using an Azerty layout, I assume it should be "Q" on your layout ).
It is really anyoing of course.
It is the second screen I received from the Ebay shop and same issue, I don't think the problem come from my side, but I just want to ask to you all if somebody have an idea or the same issue once.

Mate, I had the same problem. However it seems no one was able to help me either.
I also purchased a digitizer from Ebay for my Mozart - the exact same inverted issue occurred with me. I wasn't able to find a solution.
I'm in Australia with a T8697 model. The digitizer I received from Ebay had a circle around the windows button at the bottom - This was not on my original screen.
In the end, I purchased a digitizer from an Australian business. Cost double the Ebay digitizer did, so I hope it works... Haven't received it yet, but I'll let you know when I put it in.
What model Mozart do you own?

Cracked Screen, what do I need to fix it?

I dropped my Evo LTE yesterday and it fell flat on the screen. No case and no insurance. The glass is shattered but everything still works. I sort of wonder if my screen protector is holding the glass together right now. But the touchscreen works fine over the entire screen.
Any ideas what I need to buy from here, http://www.etradesupply.com/htc/android-models/htc-evo-4g-lte.html?
You're going to need the screen, and maybe the digitizer. I'd personally take it to sprint to fix because its gonna be cheaper than what they are charging there.
If you do it yourself, prepare for a nightmare. There are things that the repair videos don't tell you and make it look easy. The battery is basically glued in, so taking it out feels like you're breaking it. Same goes for removing the cover under the glossy back of the phone. The camera kind of sticks to that and you'll feel like you're going to rip it right off the motherboard.
I went through this twice. Installed a new front half of the phone to find the replacement didn't work. Went through the entire process again with a different screen. Too much time spent doing this that I'll never get back.
Sent from my EVO.
Some kiosks in malls do screen replacements. I'm not sure if they do EVO LTE yet but my sister iPhone screen was replaced and works wonderfully.

[Q] Galaxy SIII touch screen unresponsive

About a month ago, my fiance dropped his phone from the work truck (about seven feet) and of course, the screen cracked and had a big spider web on the upper left portion. Oddly enough, the touch screen still worked fine. While functional, the spider web annoyed him greatly, so we got a new glass screen for the phone.
We originally purchased the wrong model (he has a r530). When the screen wasn't working I took the phone to a repair shop and the guy said I very well could have gotten the wrong model screen for the phone. So we bought the correct model screen for his phone and the same thing happened. The soft buttons are working, the noise works and it lights up just fine. The LCD screen is in perfect condition and the guy at the repair shop said I replaced the screen perfectly (I used the plastic tools and a blowdryer and kept the heat away from the center of the phone and took my time. The original screen came off in one piece and I didn't run into any problems during the replacement.)
We recently ordered a new screen, thinking the last one we received may have been defective. However, after placing the new screen on the phone, the same exact issue arises where the soft keys work but the actual screen did not.
So...I was hoping for some help/advice. We really don't want to have to buy the LCD/Screen/Digitizer combo cause it's soo expensive. Could the digitizer have somehow been ruined during the replacement?
Thanks for any input you have. It is greatly appreciated.
well, did you replace the digitizer? if yes, then the issue is in the motherboard

I haven't been able to figure out how to replace just the digitizer, nor have I been able to find where to buy just a digitizer. Do you have any suggestions?
From what I understood, the digitizer was integrated into the LCD screen but I may be mistaken.
It's not the motherboard because if I take the motherboard from his phone and put it in mine everything works fine.
Search for the screen replacement how to and also you tube video .

touch is the digitizer's responsibility
