[Q] (Repair) Changing PCB Possible? - Desire Q&A, Help & Troubleshooting

Hey Fellow HTC Desire Lovers!
I have a question. Can you replace the top PCB (I think its called) the top one that has the Headphone jack and camera attached to it.
Is it a case of simply getting a replacement part from another phone and swapping the NAND flash? (I think its called the NAND flash module, Its the little square thing next to the camera)
What happened was
My HTC desire had a fist fight with the wall! it left a dent on my wall as well as on the desire!
The odd thing it Smashed the the AMOLED screen and the Housing bad! It caused the camera to be ripped from the PCB circuit board as well as the headphone jack. It is still attached but neither work. I have repaired the screen and replaced the housing (however still need the middle housing as it is still bent)
The phone works fine! Besides the camera and headphone jack and earpiece! What a beast!
Thank you for your help!

Sorry I think its called the Flex cable
Please help if anyone knows if its possible to simply swap it?
Thank you

I don't see why you couldn't swap it, as long as its the same component from another amoled handset.

wow thats great news! So it has to be a AMOLED handset to be able to work? I thought the SLCD and amoled only differed in their screens and possibly connections to the main board at the bottom?
Also when searching ebay i found flex boards that are for Nexus one. will they be ok to use? having a look at them they look exactly the same as the desire one. I cant post a link right now but will do when I can
Thank you

I'm not sure if it's totally necessary for it to be from another amoled handset, but that's how I'd do it, just as a precaution. Not sure about the nexus component.

I purchased a new one from ebay came today swapped it working fine although camera not in properly its missing the shield so its just stuck in there without the top metal to hold it in but no big deal.
For everyone that repaired their phones be careful with the digitizer strip that connects to the screen it's just held on with tape. sometimes it comes loose mine did and the phone bootlooped. I just stuck it on more firmly and its fixed using it now
Thanks ffor your help man!
And your right I don't think it matters if you have amoled or LCD . I just got a generic part for £25

[Q] Lines on replacement lcd

Hi i have just replaced the lcd on my DZ, but have now turned it on and there are vertical lines all along it.
Could i have done something wrong? not connected something? or damaged the flex cable?
Or is it just a faulty lcd?
can anyone help?

Your cable might of been damaged when you toke your phone apart. When I toke apart my moto cliq to change the screen I never has an issue. Make sure you properly put the cable on. Another thing could be the lcd...

the flex cable? yea i had been thinking that in the back of my mind. i was really careful when taking it apart though. Is there any way of testing the flex?

Problem with my Wildfire display [help please]

I have dropped my Wildfire on the floor and after i picked it up i had a spot on the screen(you can see it in the pics attached).I want to order the parts necesary from ebay because i saw they have good prices.
Please help me because i need to know..what part do i have to change to get that spot away from the screen?(the digitizer,the display?)
Thanks!
PS: the touchsreen works perfectly
really no one knows?
asking again..please help
I had exactly the same problem. That mark you see on the screen is due to dead pixels. I dropped mine too and I had a spot just like yours. Here is how I solved the problem.
1. Go to ebay and buy an LCD screen for wildfire. I got mine for less than $50. You just need the LCD not the touchscreen digitizer. I think you can get it cheaper.
2 Replace the LCD. I could not find a dissassembly guide for wildfire, but you can follow the Desire guide. They are pretty much the same. I am talking about the steps. Obviously, they different phones.
Since your touchscreen works, it is easier to replace the LCD.
Now my wildfire works fine with a working LCD.
Good luck

If the touchscreen is working without any problems then it is just the LCD Screen you need, It is a separate part from the touchscreen.
Where i used to work, the sales team used to rip people off by telling them that the touchscreen and LCD screen came together, but most of the time they don't and can be fitted separately, sometimes however they are together and need to be bought together. I have been inside one of my own wildfires to fit a new touchscreen it didn't go very well but it works......... minus the LED lights and i can tell you the LCD screen can be purchased and fitted separately.
Dude of course it is up to you wheyher you wait or not,
But i am telling you, i had the exactly same issue... My phone fell to the floor and i had the spot on the pictures you posted. It is because of the dead/stuck pixels on your lcd. My touchscreen worked fine too. Just replace the lcd and you are in bussiness.
And I agree with the poster above.

dead pixels arent good but what about my dead "lines" ? it looks like the HTC is censuring everything i want to read

[Q] HTC Desire - cracked screen + digitizer

Hey, xda dev members.
As this is my first post,I've gotta say I used the "search" function here on forum.
I just didn't find what I actually needed.
The thing is : I got my dad's HTC Desire which had been dropped on the ground.
The screen is cracked but the Digitizer looks undamaged imo.
It turns on,I can hear the startup sound,buttons light up etc.
How do I check if other parts are working properly?
I don't really trust repair shops/HTC service is too pricy and I could replace the screen/digitizer by myself with no problem.
Thank you in advance.
P.S. I can post pics if needed.
seems a bit strange that the screen is cracked but the digitizer isn't damaged, can you feel the crack with your nail?
I changed a digitizer not so long ago, it wasn't so difficult.
http://tjworld.net/blog/htc-desire-tear-down
I don't know how much a new screen will cost though.
Yeah,I'm disassembling it at the moment.
I just hate getting cheated/ripped by mobile repair centres,so I'd rather do what I can by myself.
It's strange.. Are you sure that the digitizer is not cracked?
Here in Czech Rep. the LCD for the Desire/NexusOne costs something about $70 (1300Kč)..
Sent from my HTC Desire using XDA Premium App
Here it's approx. 30 $ for digitizer and $50 for the screen.
I guess I'll order both just in case.
The thing is I don't know how to check if everything else is ok.
It was kicked hard but there's sound,button highlight,vibration etc. when I turn it on.
Anyone got idea?
I had the same problem... I crashed really hardly my phone. The digitizer and the LCD were totally broken, but everything worked (sounds, vibration, buttons etc.). So I think that your phone should work normally (besides the screen and maybe the digitizer)... my oppinion
Sent from my HTC Desire using XDA Premium App
Whoa.I'd completely disassembled it and the digitizer looks undamaged.
I haven't got any idea how it's possible since the screen is cracked all over...
[Edit] Any idea how to tell whether it's AMOLED or LCD?
I can't turn it on,so I can't use the methods involving a turned on phone.
Maybe some serial number methods or something?

Just distinguished SLCD from AMOLED by serial numbers.
60H00287 - Samsung AMOLED LCD
60H00443 -Super Sony LCD
Mine was the Samsung.
Ordering a new one,thanks for helping me out.
Can be locked.
For how much?
Sent from my HTC Desire using XDA Premium App
Unfortunately,it's AMOLED,so it costs ~60$(190 PLN).
Sorry for doubleposting but I'm not sure if editing a post will bring the topic up.
I found out that the digitizer connector is probably broken. (pic included)
Any idea if I can get it fixed anywhere?
Please use the Q&A Forum for questions Thanks

My friend,this is the same horror that i faced and yet not recovered completely from its impact.... The problem is with your touchscreen a.k.a digitizer which probably would have been known to you(as you mentioned you have googled a lot).My best advice is to change it in HTC service center itself,bcause i bought it in market and fixed it(though i was very careful in following each and every step) after few days of ruf-tuf usage the problem showed up again...So go for HTC Service they are the best doctors..
Before you buy new digitizer
and only if your warrenty has expired, try to open the phone (there is enough youtube videos), remove the digitizer and look at the black soft plstic ribbon that goes around the front plastic panel (the one that protects the lcd).
If it is little loose and not hard tight to the frame you can use a piece of plastic to attach it to the frame and check the touch responses again (that worked for me...)
else, buy a new digitizer (about 4-5 USD in eBay).

I've done a HTC wildfire digitizer swap before its fairly straight forward I found a guy on eBay from Poland I believe that sold pre-Cut stickers for attaching the digitizer to the LCD. I would have a look if you can and get one of them if you intend to move forward with the replacement, just make sure to remove as much of the excess glue from the old sticker first

Screen not showing image

I've recently ran into an issue where the screen on my dz does not show anything on it. The phone works and responds to touch however it does not show anything on the screen apart from a couple of white lined down the right side. Would this be a screen fault or a connector fault with the ribbon?

It could be either the main flex cable or the LCD, unfortunately there isn't a good way of testing other than replacing pieces to see what cause this. In truth your situation seems to be 50/50 caused by main flex or LCD, but I still am leaning toward replacing the LCD if you don't want to buy both
