[Q] Help needed guys! Digitizer problems! - HTC Vivid, Raider, Velocity

Hello guys have a problem with my htc vivid's(have 2 of them)!
To start the story with i got a cracked vivid phone from ebay and thought of replacing the screen, i also got a digitizer from some hong-kong seller, the screen arrived and i looked up some videos on youtube and fixed the screen myself, everything seemed to have gone fine, but when i switched on the phone after replacement the bottom half of the screen would not work! only the top hald of the screen worked, i assumed it was a faulty digitizer and ordered another digitizer!
Meanwhile i got another vivid off ebay, this was also a damaged one ( the seller told the LCD was dimming but digitizer was working) so i thought of replacing its LCD and got it off, this phone also arrived so i had one phone with bad digitizer and other with bad LCD i ordered an LCD also so b4 it arrives i thought i would change the digitizer from the bad LCD phone to the bad digitizer phone so i will have one complete working phone!
When i started to open the bad LCD phone i realised it was a water damaged phone, but the digitizer was fine so i removed its digitizer carefully and put onto the bad digitizer phone and switched it on, but again the same problem! top half woking bottom half not working! so i thought ill change the motherboard of the bad digitizer phone with the bad LCD phone and after doing that the digitizer would not work at all!!
i dunno what to do now i dunno where im going wrong any sort of help or duggestions would be greatly appreciated, and if you guys are having hard time understanding any part of the story let me know will try to explain that part as clearly as possible, thanks in advance! hope i get ou of this problem soon

Are you sure that both motherboards were in working order.? I would suspect the motherboard you installed is faulty...is that motherboard the one which was on the waterdamaged phone? If it were me I would put the motherboard back in that at least had the screen half on and then troubleshoot from there....I've replaced a few screens but not enough to give a good resolution...I would proceed by process of elimination on components you know, for sure, are working before you install them...and its totally plausable that a new replacement part can be faulty...I'm not sure man, just my two cents worth...I would scour xda for others who have had screen issues..one post probably won't fix your particular issue but a few different ones might...ill look too and post link if I find something...

Damaged Digitizer or LCD Screen? Help please :(

Hi,
Last night I knocked a small table and my girlfriends phone and a remote for the TV fell off.
We noticed that her phone now has a ring of black dots on the screen, mostly visible with a white background (E.G websites) but also from the home screen and the like.
We think she's cancelled her phone insurance, as she's never had a payment out to the company.
Can anyone tell me if its a Digitizer (What is one of these? Is it just the touch screen sensitive part of the phone?) Or the actual LCD Screen itself?
If you click on the photo it will load a larger image
Thanks for any assistance, kinda annoyed about this and wondering if I can repair myself with the parts on ebay. Or does anyone know how much HTC Charge to repair similar? Either in $USD, £GBP or €Eur, I can convert and get a ball park figure.
Hi
First of all is the phone still in warranty? If so take it back to an HTC dealer they should repair it for you for free. TD2 screens are not very good and it's a common fault. ( i had to have mine repaired after just only 3 weeks! )
The TD2 screen is made out of 2 parts, The touch screen or the 'digitizer' as you call it and a normal LCD screen underneath. You need to establish which has gone faulty.
If the touch screen still operates normally i.e the screen does not lock up or freeze and allows you to navigate normally then its the lcd screen below. If the touch screen is faulty one good way of checking is to put a piece of tape over the damaged area and try to lift it up a little to see if the marks / dots disappear and functionality can temporarily be restored.
Its hard to tell from your picture which it is..... sorry
I'm not sure how much a replacement by a dealer would cost, but i'm sure you can replace either yourself. ebay is a good place to look
Hope this helps.
I've had a reply from HTC UK who said the following:
That looks like there are a bunch of very small cracks in the screen. the black stuff is likely the Liquid Crystal from inside the display that has leaked out. If the dots get larger then it would definitely seem that the screen has got some cracks in it.
if this is the case, the standard charge for replacing the LCD is around £180 as sadly it is all one complete unit on the diamond 2, so it is not just the LCD underneath that needs to be replaced, but the whole screen assembly including the touchscreen layer and the actual LCD.
I hope this information helps you to make up your mind.
best regards,

I'll see if I can find any HTC Dealer who will send it off on my behalf, but may just end up buying this: http://cgi.ebay.co.uk/LCD-Screen-Di...UK_Mobiles_Accessories_RL?hash=item588362a12d
Hi mate,
had the same problem...
the item you psetd from ebay is not the one you need to change.
you need a digitizer, not an lcd screen.
i got one from ebay (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItemVersion&item=290376721935&view=all&tid=393718237019), it includes both the lcd and the digitizer, you can check ebay to find other auctions offering the digitizer only.
you can change the digitizer on your own if you don't mind loosing the waranty of your phone.
cheers
Hi,
I had already found this: http://cgi.ebay.co.uk/Touch-Screen-...UK_Mobiles_Accessories_RL?hash=item5882e7ef74
Will buy in a bit, funds are a bit short today.
The Touch Screen's functionality hasn't changed at all though, no sticking buttons or anything. So I suspect that its the LCD Screen thats damaged but will follow you're advise as you're going to have more experiance than me (and its the cheaper part to begin with!)
Scrap the above post.. my g/f has just told me that the dots on her phone are bigger/worse. Looks like its the LCD Screen afterall
i still believe it is not the LCD.
the digitizer is actually sitted on a glass, and the LCD is below that. it is very difficult to harm the LCD. i also though it was the LCD (at least i wasn't sure which was broken) so i ordered both of them.
if you disasseble the phone you will be sure if it is the LCD or not.
i vote for the digitizer
good luck, if you need any help, i'll be pleased to help you..
Just to update, A few days after I posted and got helpful advice on here.. she called me up to say the dots have disappeared, and they have still gone now a few days after.
She said she put it in the office where she works, under a printer paper tray, and the office was warm. Something has (maybe only temporarily) fixed it.
I´m having the same exact problem my nephew dropped my phone, i already dissemble it because i was not sure of the lcd type, but when i looked at the digitizer i didn´t see any dots, so i´m not sure what to repair, TS or Digitizer, i allready tried with the tape to pull the digitizer, when it was apart i couldn´t see anything on the lcd no marks at all, opinions please.
cheers
Well F**K me! just bought a second hand diamond 2 to replace my xperia...
...seemed to work great checking it out... went home with the phone in my pocket... and as soon as I turn it on the touch screen doesn't work
dissected the whole phone only to discover the digitizer is glued to the bezel!
I ordered this from Ebay, will update if I got it working with the brand new housing + digitizer: http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=380166349182&ssPageName=STRK:MEWNX:IT
fingeres crossed
Please report back here on this thread if it works

If you can make some photos of the digitizer and the lcd dissasembled maybe, but It seems unlikely to break the lcd when you didn't completely trashed your digitizer.

Also the LCD didn´t had any marks at all, but i´m going to buy the TS+LCD and replaced by parts first the lcd because it´s a lot easier to replace then if the problem persists the TS.
I will post the result later when i get the parts to replace.

Can anyone confirm the above link as being both Lcd and Digitizer? I'm sure it doesn't mention it in the listing but the picture looks like it's showing both connectors.
Most likely only the LCD that's my conclusion if you look at the sellers store.
But to be sure e-mail the seller and ask.

Soooooo, as I've already posted here, My digitizer was busted on the phone I just bought... what I didn't tell was that I ordered a digitizer, then checked if I could remove it easily...came to the conclusion that I couldn't... and ordered a digitizer+housing so I could easily fit it on.
the mail brought me the digitizer today, and while knowing a better solution was on it's way I couldn't resist and try if I could make it work.
Turns out it super easy to seperate the digitizer from the bezel using a hairdryer (softening the glue) and a knife:
Take your phone apart, just the 4 screws, click the plastic center off it. Remove the digitizer cable, the touchscreen cable and the speaker cable.
now you are able to remove the green plate which holds all chips and stuff.
underneath that is the screen, lift it up gently going under it from the gap the removal of volume buttons leaves, put it away safely.
Now remove the speaker, the buttons under the zoom bar, and the power button(don't forget the the power button, and rubbery thingy that falls out of the bottom, the hole needs to be at the bottom when putting it back in).
your phone should be completely empty by now... just the front and the digitize glued together.
make the front of the phone reaaaaaaaaaallllly hot, put the knive between the metal and the digitizer (I started at the part where the zoombar is) and gently push it between the two parts... (from the inside of the phone to the oudside). Now just keep the whole thing above the dryer to keep it warm and slowly slice your way around the phone (no secret wires are there that you can cut through).
I used some random glue I had lying around to glue the front back to the new digitizer... perfect!
so the screen is like new now
ps bought this digitizer: http://cgi.ebay.nl/Touch-Screen-Dig...wItemQQptZPDA_Accessories?hash=item45eed6effc
Thanks for that jodeltje.
It sounds exactly the same as when i replaced the digitizer on an Omnia. Really not as hard as one might imagine. Taking your time and being careful are the most important things.
Hey guys,
I came into same boat last night.
Dropped my T-Mobile MDA Compact V from 2.5ft table, Backwards (Not towards LCD) and now it has black dots on screen. I guess the LCD has pressed backwards by chip sets.
Here is a screenshot.
I think its LCD damaged but I don't have cash to replace nor device warranty.
Do you think the problem solves eventually? Coz once I had dropped sony mobile and it too had same issue but solved after many days.
Hopefully it solves.
BTW; does LCD affixed to Digitizer? by seeing service manual, it doesn't look like it is. And I afraid to get cheap hongkong LCD screens for about 30$ since they won't be true quality display. i.e blueish.
Thanks...
Best Regards
hello CRACING,
sorry about what happened to you...
from the picture i can say that you have a problem with the digitizer...
your LCD is ok.
i tend to have this problem over and over again the last 1,5 years... i replace the digitizer (or the glass on which the digitizer is attached to) every 3-4 months..
yes the ones you get from ebay are not that good quiality, but well it keeps the phone working...
if you need assistance on replacing the digitizer, i can help you, by providing pictures and istructions...
cheers

Urgent help with digitizer

I recently broke the screen of my Leo T8585 and replaced the LCD + Digitizer with an original Hong Kong part.
After disconecting the working shattered part the digitizer never worked again. Even the shattered one ceased to work completely (LCD is working fine but digitizer has no response). A second replacement part was ordered and the problem persists, ie, replacement part is not the problem. Also part number is correct.
Can anyone tell me if there is a specific precedure for this replacement? Could there be a hardware/software lock I need to open? Strip contacts have been checked and are fine.
thanks in advance
:O damn, a lot of people getting their HD2s smashed, here i was thinking i was the only one. I recently replaced my digitizer & LCD aswell.
As far as i know there is no soft/hardware locks present. In case you have checked that allll connectors are properly connected i can only guess that an electrostatic discharge might have caused damage to the hardware. . . But in case you were wearing an ESD wrist strap which i recommend using (by no means i don't want to sound like a smartass) i havn't got a faintest idea
Well.. replying to a totally old post but.. what the hell, maybe it will help and/or help others who encounter similar problems.

nexus one digitizer repair gone wrong

Hi, i replaced my digitizer on my nexus. I have found that part of the digitizer works and some of it doesn't. Anyways after trying to find where the problem is i've located it to be the connector where the digitizer attaches. Does anyone know where or if i can get a replacement board from?
XDA is no longer worth my time.
Did you ever solve this? I think I'm going through the same thing. I replaced my digitizer last night and this morning I've got a band across the middle that is non-responsive.

Screen Re calibrate?

The very right side edge of the screen isnt working on my wifes phone. Is it a hardware issue? or just in need of recalibration? Known issue? Thanks
It's a hardware issue. The digitizer is going bad. There are posts about people "repairing" them with hair driers and ovens. You can also buy a replacement on ebay and attempt to replace it.
Hey! I got the same issue on my A853 Milestone (ghost touch, then some parts of the screen not working anymore). The problem is not necessarily on the digitizer. I suggest you to disassemble the phone and to verify the integrity of the flex cable. Mine was very used and I made the same mistake - I spent money on a new digitizer without checking the other component. So, first check that then buy the right part. Good luck! Best wishes from RO!

[Q] TouchPad Digitizer Issues?

Just "scored" a 32 gb HP TP off CL for $100..only thing is he informed me that the touch screen was a little glitchy at times. So, I just decided to take it apart and fix it myself since it was already halfway opened Actually the digitizer wasnt even glued sufficient because while prying the case open, the digitizer came unstuck. So I didnt have to remove anything from the bezel just unclip the connectors and analyze the problem. I haven't gotten the replacement digitizer yet. Just wondering if this replacement or any of the other numerous listings on ebay would be ok before i bought it.
Also, he said he replaced the digitizer before..could the problem not be with the digitizer? When I opened everything up and reattached the connectors, it seemed like it functioned better than before but it was still a dead zone. Holding the TP upright, the row containing the numerical buttons dont function, as well as certain portions to the top of the device.
You need a new digitizer control board, not digitizer glass. And as far as I know they are not sold.

ugh...i wonder what goes wrong with the boards. It seems like its really nothing on them that could mess up unless a solder joint is bad or bent,etc. But the "good" news is it looks like he didnt try to replace the digitizer at all or if he did he put in an OEM replacement but i think thats highly doubtable. The digitizer has the same OEM stickers as the ones on the motherboards and every where else. So im holding out hope that the new replacement may correct the problem but..idk..
Side note:
Ok..im not understanding why the douche chose to try and repair it himself when it's still actually within the year warranty. He got it in DEC 2011...warranty is good til' October 2012 it says. I talked to HP and they said it was under warranty and sent me a box to ship it back. I was going to ship it back, but upon further inspection you can see where the azz pryed open the case. I didn't want to prolong the process of getting it fixed by having them just tell me that i voided the warranty,and sending it back to me...so i opted to do it myself. Any one have any testimonials with sending back opened Touchpads? Do they inspect them "good" before repairing?
If all else fails i guess ill just take the chance and send it back to HP.
update:
Just Received the digitizer from the ebay store posted in my first post. Works like a charm...guessing it was just the digitizer after all. Im now the proud owner of a 32gb HP Touchpad for $124.89 Case Closed!
