[Q] HTC HD2 digitizer replacement problem. - General Questions and Answers

I'm new here and apologize for my english.
From the beginning then.I had my hd2 for about 2 months.I didn't like the sound loudness so taught i replace the loudspeaker.After putting it together digitizer didn't work.I noticed a very small crack in the digitizer so i taught that is the problem but wasn't sure and am still not cause i have seen digitizers with many cracks and still working.I ordered a new digitizer it wasn't the same that i had before cause this one has a T-Mobile logo on it but the connector is the same and it still doesn't work.
So, my questions are:
1)can it be that it's not digitizers problem?
2)Is there any difference what digitizer i use (with or without the T-mobile logo)?
I really don't want to waste anymore money on it (cause these digitizers are not cheap and i want to be sure) but i really want to fix it.Using Desire now but really miss my HD2 (except battery performance)
NB: I have looked around and found similar posts.But maybe someone has had same problem and can ensure this.

How to Figure out if touchscreen or LCD or both are broken?

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)

[Q] Nexus One main microphone repair/replacement?

Hi all,
I've recently had a crash - my N1 fell out from my pocket while climbing (stupid, I know..) - cracked screen, all that.. I've managed to replace the digitizer without big problems, but I have a more serious issue: the main (built-in) microphone stopped working and now I have to use the headset for every call
I've sent it to HTC service and they said the motherboard needs replacing and wanted me to pay 300$ for it..
Since it's quite a lot for a microphone, before buying the new one (at least 200$ for tho mobo alone) or sending it again to the HTC guys for repair, I'd like to ask you if there is anybody who had anything to do with those microphones or issues similar to mine.
The microphone itself is a small gold rectangle-shaped thing glued to the motherboard, but I cannot make out any markings on it (there seems to be something written on it, it's just not readable any more). It seems to be exactly the same as the noise-cancelling one near in the upper part of the phone. Of course, before cutting or soldering anything I'd like to know as much as I can..
So.. the questions are:
Has anyone repaired a thing like that or managed to replace a microphone on Nexus One motherboard? How could this be done?
Does anybody know where I could buy a microphone that would match?
I know it's a long shot (and a long post ), but I figured it's worth a try to look for somebody who might have some insight.
Thanks in advance,
Kuba
P.S. Could anyone move this question to Q&A, please?..first post gone wrong..
you could just buy a new one for under 300$ on ebay or a used one for less than 220 for everything new If something like that is messed up its not worth fixing, too much work
hitmanre,
thanks for the reply, but...
As I said, I figured the part on buying another mobo (or a broken N1 for parts) on my own.
I was just curious - from a DYI perspective - what's going on on the board and what's actually broken around the microphone.. If it was only the microphone then it should be easy enough to replace - but if it's a crack somewhere in the inner layers of the board, then bummer..
In fact, I opened my N1 again yesterday and cut the mic out...curious thing is that there seem to be only one connected soldered part between mobo ant the mic.. Could anyone explain how a microphone could work with a single connector? there doesn't seem to be any ground connection anywhere..
If I have some time, I'll post photos - but no sooner than in a week - going on vacation
See you,
Kuba
I have the same problem, and I live outside the service coverage area. I've had my Nexus One since May 2010, so it was more than one year old. It's really sad to quit such a really nice phone just because it can't make phone calls. It seems that nobody here in Lima know how to repair a N1. And I'm so afraid to open it...
I have seen 2 of these phones with the same issue. one mine and second a customers. and I have tried replacing the mic headset jack (headset jack can short out audio) and still nothing. mic works with loudspeaker but not in normal mode with earspeaker.
ok today I was able to get my hands on a working nexus. and swapped the upper flex and that fixed it.
the only thing is that we ordered this part from one of our sources to fix a power button (which is on the same part) and it had this issue. so I had to replace it again

I also have a problem with the mic suddenly not working and working again suddenly. So it must be a damaged flex since the phone has a dent on the upper left part of it.

Phone dropped, screen dead... Options?

Hey guys, the GF left her phone up high and was knocked down and now the screen seems to be dead. Lights up for a moment when turning on then just goes dark. Pretty sure it's operating fine underneath (still need to plug in to computer to check for connectivity), but assuming just the screen needs to be replaced, what are my options?
Is that something I could possibly replace or perhaps send it off to somebody on this forum for repair? How much ($) are we looking to fix? Better to just sell on ebay?
Thanks!
I did a quick search on ebay concerning a new LCD for the Atrix 2 and they seem to cost around 80 bucks... I don't know if that would be a worthy investment since depending on your contract you can maybe get a new one for about that price...
What I can tell you from personal experience is that it is most likely to be a major pain in the ass to replace the screen on your own... I once changed the front frame of my HTC Desire and I basically had to disassemble EVERYTHING including unglue-ing the touchpanel from the frame taking out all sorts of boards and stuff, and I never got rid of the little dust that would get between digitizer and LCD..... (the memories )
But I'd say if you're confident in your technical skills and a new LCD would be worth your money then you might consider going for it...
I don't know but I'd estimate the cost of a professional repair around $150-$200...
One tip just in case: Make sure that no dust gets onto your screen/on the inside of your tuchpanel because once you start "cleaning" it off (with a towel) you'll never get it as clean as it was...

any one have the schematic?

so i recently purchased a used doubleshot to give to my fiance, her biggest deal about a phone seems to be the camera and her g2 just isnt cutting it. well im cheap and handy so i buy all my phones broken and just fix them.
i found this almost mint doubleshot for about $50 with the only problem being the internal speaker is shot. so this is should be a hardware fault most likely but to be safe i rooted it and gained radio s-off and flashed a few roms. definitely hardware. so i bought a speaker for $7 (should be here by weeks end) and looking around i see the main flex being sold with the internal speaker attached. this got me wondering if the speaker simply sits against the contact points (my experience on well every phone ive disassembled) or is it soldered or what?
i dont mind doing the extra effort but google has not explained to me what i should expect. i even called htc and of course got the id love to help but i just cant response. so if anyone has experience with this or can point me to a full breakdown (not just digitizer replacement as it skips this) i would be forever grateful. thanks!
Here is a guide to help aid you in the taking apart of a doubleshot.. I'm not sure what help it is, but this is all I can personally help you with as I haven't any experience with this. http://forum.xda-developers.com/showthread.php?t=1586028

Send a message to jjbz. I traded my bricked DS for a working one with him and he said he's going to use my old one for parts.
Sent from Spaceball One.
The internal speaker is soldered down to the ribbon cable. If you are going to attempt to replace it yourself be vary careful of the light and proximity sensors. I fried the proximity sensor when I attempted to solder in a new speaker. After a month of dealing with the missing proximity sensor, I went with a new ribbon cable.

[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.
