[Q] On digitizer models - Desire Q&A, Help & Troubleshooting

Hi.
I broke my digitizer on my Desire (white model with SLCD, if that matters ), and is now looking for a replacement.
My current digitizer is a Synaptics 940-682-1RA, and it says "A6" with large letters inside a white square printed on the cable. Lots of replacement digitizers are available on eBay, but they all have different model numbers / two-letter code in the square (J4, B9, D4 to name a few).
Google does not seem to return much information on compatibility between different digitizers, so I wanted to ask here
Which digitizers can be used in various models - and more specifically, which can replace the one I'm using?

Hi there, did you have any success with replacing your digitizer? I am in the same situtation with the same digitizer part number. I ordered a replacement but had not realised there different versions out there.
Regards,
Gareth

[Q] HTC Desire Digitizer replacement

Hello,
My wife recently had the misfortune to drop her newish HTC Desire A8183 on the kitchen floor, thanks to my daughter's over eager grab. The digitizer has some lovely cracks all over it now... :-(
Needless to say, my wife is dismayed, and my daughter (she's only 3 and didn't mean it) is very sorry.
I thought I'd try replacing the digitizer myself, having read many tales of repairs taking 3 weeks and costing 300+ dollars.
Bought a new digitizer, took phone apart (even had a handy little "oven" that I could set to 60 degrees to melt the glue).
Phone taken to pieces quite happily.
Put in new digitizer, reassemble.
Now start up phone, all looks good.
BUT... only a small section of the screen is responding to touch (where the 7,8,9) keys are when entering SIM PIN. The row below has also worked (although intermittently) and the emergency call button too...
So my question:
Is this a problem with the digitizer I bought? Is there a particular model number of digitizers that I should be using? I note that the old digitizer had an "I2" printed on the pcb, whereas the new one has an "E5", the old one has a sticker with SHAB1 on it whereas the new on has SHABN...
I'm not sure that this is important - but given that the thing only partly works, I think it might be.
Anyone got any ideas/hints for me to try... I'll phone the supplier tomorrow and suggest to them that the part is faulty, as I can't see any threads out there where this has happened to someone else.
EDIT: I thought I should add that the old digitizer despite looking like a spider's web, still actually works - which really make me think it is a problem with the new one...
Thanks for any help!
Chris
I can't really help you from experience all knowledge.
But I did read somewhere that you have to use specific digitizer for specific Desires.
I could be wrong
Did you work out any solution for your replacement digitizer issue?
I have a similar problem and I just realized the different ghost pattern of the screens (original has diagonal, new has square arrangements of dots) and also the electronics of the digitizer is slightly different (Original: Synaptics 940-663-1R1, replacement: Synaptics 940-682-1R2)
Hello,
I'v got the same problem, i even bought two digitizers from different sellers. I thought that it is because i did something wrong when I disassembly and assembled the phone but I put my old digitizer again and it works ok ( except the corner where it's crashed ).I asked my sellers if there are some different digitizers and they replayed that no and the one I'v got are checked and ok ( the electronics is identical, the only difference are white big number E2 and G2 ). What can I do more to repair my poor thing?

[Q] Digitzer replacement

Hi there, I cracked my Desire's digitizer and tried to replace and subsequently damaged the LCD screen (Sony version). Having had a further look online I noticed that there appear to be a few different digitizer part numbers. Mine (the broken one) is 940-682-1RA, however any that I have seen online for sale (ebay) are ending in 1R1. I have also seen others reporting that there are ones with a number ending 1R2. Does anybody know if I need a digitizer with a matching part number or will any of the others work ok?
I had replaced the digitizer on mine but didnt get a chance to test it was working properly as I must have bent the LCD panel too much during disassembly and broke it. I have ordered a new LCD and hope to fit it soon, but wanted to check about the digitizer in case I need to send it back and order the correct one. Grateful for any advice you can offer.
Many thanks
Gareth

[Q] Screen replacement

Hi. I just got a used HTC One X phone, but the digitizer is cracked. I understood that I can't change only the digitizer, so I wanna buy a digitizer+LCD display assebmly. Now I have a problem. Reading on the internet I found that there are 2 different screens, with green and yellow flex cable. Which one is for my phone? I have the international version with Tegra 3.

if you are going to change it youself then best to open your hox and match the serial number
My idea was to open the phone after I have all parts (want to change the housing and display assembly) from ebay. I saw that they ship the parts with tools, because now I don't have any.
Sorry for double post, but I wanted to tell you that I managed to change my LCD display. I bought this one: http://www.ebay.com/itm/111039746173?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 and I am very glad. I didn't noticed any contrast/color differences. Everything worked as it should, except vibrate, which doesn't work anymore and I don't know why, I triple checked the connectors of the vibrator.
If someone want to change by himself, just go to service I had a very hard time to take the phone apart (I also changed the back case cover).
Oh, the old LCD had panel_vendor and panel_id 944701. Same with the new one.

[Q] LCD touchscreen/digitizer part numbers

I realize that this is a hardware question on a site that isn't particularly focused on parts, but I'm frustrated and looking for input, and there are a lot of knowledgeable people here.
I spiderwebbed the touchscreen digitizer glass on my AT&T Tab S 8.4 SM-T707A. Samsung USA will do in-house repair on the unit, but it will take about 2 weeks with shipping, and cost $265 USD. I'm looking for another option.
BUT
I can't seem to find a replacement part anywhere, and I can't seem to find any kind of parts list or compatibility list either. I *can* find parts for the T700 and T705:
at aliexpress & parts4repair (sorry new poster, so no links)
laptopscreen.com has a listing for the Tab S 8.4", but the details within the listing (screen dimensions) are incorrect (they are for the 10.1"), and we all know there are a handful of different models, and the screen details are NOT identical across them.
It appears that the LCD and touchscreen digitizer are a single unit for replacement. Samsung USA would not tell me the part number, and insisted that the unit is "not user serviceable".
Any suggestions?
I found a few on eBay but it was cheaper just paying Samsung to fix it. A local fix it store said he'd try to separate screen from LCD but offered no guarantee of not breaking it. Sending to Sammy was my best option.

Nexus 7 2013: touch screen unresponsive after replacement

Hello everyone,
the screen of my N7 2013 cracked after his first fall on the ground... the tablet still worked but the touch screen was unresponsive, so I decided to replace it and bought a new screen and digitizer. I replaced it following youtube tutorials but the new touch screen was unresponsive. I thought the replacement i bought was faulty, so I wrote to the seller who refunded me. So I bought a SECOND lcd+digitizer replacement, from a different seller. Same story: after replacement this second digitizer is totally unresponsive too.
I checked connections so many times with no luck. I can't believe that I bought TWO broken digitizers from two different sellers. I don't think I broke something else working on replacement (but I cannot be sure ).
So I'm wondering if there is any possible software cause for this touch screen behaviour... is there something I can still try to do before throw away the tablet? Anyone can help?
Thank you!

You only replaced the touch screen or also the daughter board? Is there any revision number on the screens/cables?
Sent from my Nexus 7 using XDA Free mobile app
I only replaced digitizer and lcd, daughter board was the original one (rev 1.4).
The old digitizer had a sticker with a qr code and some numbers on it, and another code printed on (see pic ..935).
I found no reference for these codes on google, the qr code gives no results.
The new digitizer has no sticker and no codes printed, only a printed mark displaying "cx 2015-1" (I think it's a seller's mark).
On lower part, where circuits and cable are, the original digitizer shows two other numbers (see pic ..942).
New digitizer shows two numbers too, smaller one (ME050111) is the same, except for last two numbers (original digitizer has "01", new digitizer has "12"). The biggest number (343308Q in the pic) is completely different on the new digitizer.
