[Q] Non Responsive Screen - HD2 Android Q&A, Help & Troubleshooting and Genera

Have an HD2 here that stupidly I disassembled to replace the camera lens which after reading XDA deep enough I found out that it is replaced from the outside. Well got the phone apart and figured out that that wasn't necessary I reassembled the phone. Well in the process of getting the back off I appear to have damaged the cable the runs up the side of the screen on the volume button side. The digitizer I am told. Knowing this was beyond me I found a repair facility Mission Repair in Kansas that said they could repair it. Shipped it to them and they said that they replaced the digitizer and the lcd screen and neither one fixed the problem. They seemed truly sincere and did not charge me anything but shipping. They said must be the logic board and that was not an affordable piece to replace.
Seems strange to me that the phone was working perfectly before the cable damage that I caused. I did not approach the logic board area at all. Phone running NDT MIUI 19.1 when this happened. Any thoughts from you gurus that maybe they missed.
Thanks in advance

mayve ur ESD dammage it or u touched something and u didnt pay attention ... tru to flash the rom again or look again inside

I want your broken wizard!

Please, its been about a month since the earpiece on my wizard died and i can't find the part anywhere! I found one damaged wizard on ebay which sold for $400 with a damaged screen! obviously a fradulent buyer but the seller hasn't replied yet.
So if your wizard is water damaged, smashed, or simply inoperable i need this one part to fix my earpiece. Also my brothers wizard's speakers are blown so it'd be great if i could get a hold of those two.
What i need is the ribbon cable which connected the main board to the top sliding half of the device. Its a ribbon cable attached to a circuit board on both ends.
Please i really need this so i can bring the phone part of my wizard back to life.
PM me if you know where i can get this part or if you have a damaged wizard.
Thanks in advance!
broken wizard!
i do have a working one with cracked screen. where are you located?
i should have mentioned that.. I'm in austin, texas. If u are over seas i can check to see if i can make it elligible for a corporate rate to ship it to me.
Also how much would u be wanted for it?
I'd offer you mine, but I got the same thing broken.
i just emailed 2 sellers on ebay which have cellphone parts and wizard housings in there stores, awaiting there reply. And i'm working something out with the one person with a damaged one from ebay.
What do you guys think $85 good for a wizard with a damaged screen?
broken wizard
I have a broken wizard--I dropped it, but I can still make calls from it via the bluetooth headset.
PM me if you are interested and I'll give you my phone #.
I've pm'd u, but does that mean your earpiece is broken as well? Cuz what i need is the ribbon cable that powers the earpiece, LCD, digitizer, softkeys, and everything else on the front half of the device. So if yours is broken then probably won't help mine out much.
i guess so. If you need an intact (front) then mine won't help--due to the fact that the "cal answer/hangup " buttons do not work.
The damaged one i bought off ebay came in today, swapped the parts out and now my earpiece is working again!! i'm so excited!!
Now i have all these parts lying around if anyone needs anything send them my way. The parts i got are:
The main board
Camera
Vibrator
Main housing (except for the front its really banged up)
Antenna
Keyboard
But no battery cover, didn't come with one.
Heres a pic of the mess i had on my desk but it all worked out perfectly
--------------------------------------------------------------------------------------------
I no longer have the damaged wizard so please don't PM asking for parts.
hey fone_fanatic, wondering if you ever experienced your Wizard creaking when you press down on the front faceplate(below the call/end buttons)....seems to come from the hinge right under the the right soft key (the one connected to the keyboard), only thing is it only makes noise when the keyboard is closed and my keyboard is not loose at all(nice and snug)....just wanted to know if you might know of a fix for my problem, would you recommend me taking it apart or just sending it in for a warranty repair or do you know if it is pretty easy to somehow shorten the gap between the front face and the keyboard?.... appreciate the time.
Regards,
P.S. My Wizard works fine, its just starting to get very annoying when I make/end phone calls.
no, mine doesn't make any noise when i press down there. well there is a noise but its coming from the battery cover. if your device is under warranty, i suggest sending it in if it bothers you that much. the reason being because when u open it up your bound to break a couple of clips which might make it worse.
fone_fanatic: I love that mess on your desk
You might want to mask out your First National Card though - edge detection filters would love that image...
V
don't worry about the card, its one of those advertisement cards you get in the mail syaing your pre-approved or whatever. i always keep those cards and use them with taking devices apart.

anyone got a 8125 with a cracked LCD but all other functions still working?
yes, i'm aware of pocket pc techs but they didn't have the part i needed to fix mine whihc is why i bought a damaged one and salvaged the part i needed out of it. Now i've got all these extra parts , but what to do with them...?
@ fone_fanatic
thanks for the advice....off to warranty it goes...hope it comes back with no new problems (fingers tightly crossed)....
Regards,
hey can I see that pic of the parts u got left?
I wouldnt mind buying a wizard with just a broken LCD if it was cheap. $180 to send it in to fix a LCD is super expensive when the phone is like $350 on ebay

The reason i bought it the this one with the damaged lcd is because i couldn't find the part i needed (Rigid Flex Board) anywhere so i swapped my broken one out with this one. So if i was to put this back together not only would the lcd be busted but the earpiece won't work also the speakers would be blown (sold good speakers to a friend). Also the front case is heavily scratched/dinged, looks like someone smashed a brick on the phone.

[Q] how hard is a full lcd + digitizer replacement?

Hello All,
My Leo took a terrible tumble, and the digitizer is smashed. For as bad as it looks, amazingly the digitizer and lcd still work, as do all of the cell functions. The lcd is showing lots of artifacts, making it difficult but not impossible to use the Leo.
So if I want to try and repair the Leo myself I will need to purchase a full lcd + digitizer. I know it is a pain to try and replace just the digitizer, and am almost glad in a way that if I am going to repair it I'll have to buy the full lcd + digitizer.
So it is "relatively" easy to replace the full lcd + digitizer (i.e. will I have to tear it all the way down) or is the replacement less involved?
Thanks.
Yeah you'll have to tear it apart pretty good, and I've read reports of button failures, loss of wifi signal(antenna damage), and other problems after a bad lcd/digitizer replacement.
My opinion, just ship it off to one of the repair shops and have them do it. They have all the right tools, lots of experience, and if they screw up your phone, you can send it back and have them fix it as long as they're a decent shop.
But if you're feeling adventurous, go right ahead, I don't know your skill level so maybe it's not beyond your range. Just read up ALOT before you try anything. There used to be a pretty good disassembly guide somewhere in the HD2 forums, with a video and everything. Good luck and BE CAREFUL !
http://forum.xda-developers.com/showthread.php?t=613954
see that thread
Dont try to replace it by your self, you will have to tear the whole phone down, and its a pain it the ass...and yes there are some button issues when connecting them again to the motherboard, flex cables in hd2 are realy in very poor condition, they are cheap, and well they just brake inside. I had 2 faulty hd 2's and assembled 1 working from them, and had button issues, when I checked flex cables with microscope well, micro teardown's in flex cable...so to fragile...you need to be very carefull...in my opinion its better to sent it to HTC and let them repair your phone...it would not be as much differece in price...just not worth to risk...

Hey, its no problem. I just did it myself. The video on the Crunchgear website is soooo systematic and detailed, I had no problem at all. I watched it 4 times, and then went through the steps easy peasy. (Instead of the oven that they mention, I just put it on my radiator for 10 mins)
I would however warn you to be verrrrry (very very very) careful while removing the so called "AP FPC" ribbon cable at the bottom. That darn thing is so flimsy...
Good luck!

Don't understand why people always make a problem about the AP FPC.
Just let it on it's place and only open the bridge.
I have repaired like 20 of those HD2's and had never a problem with the AP FPC.
Only open the bridge and remove, that's it..
I would warn you about a more darn thing, the volume fpc. If you forget it, you will never can flash you HD2 again. Yes okay, you can change, but then you have to change the whole main flex.
If you don't have the expertise to do this kind of repairs, then I would say don't do it. It cost you more then a repaircenter if you fail.
There are too much little parts that can damage or break.
But the disassembly and assembly proces is not really hard, the most time is to remove the frame from the broken LCM module, and replace it with a new LCM module. You have to use and make lots of adhesive.

[Q] Tmo G2 No video issue (Self-replaced parts)

So i've read through the stickies and havnt come across anything really substantial, tho I have seen a few other user posts about their G2 suddenly losing video.
That's the issue I'm having.
Here's a little history for you:
Customer brought this phone in to me, said it had water damage. Bought it off them to tinker with myself. I opened it up, and sure enough there were some water stains on the flex cable and the back of the LCD. I replaced both with brand new parts, and now the phone boots, but has only a black screen. It receives calls, touchscreen works, makes clicking noises, all that jazz.... just no video
I've pulled all the rf shields off the logic board to take a peek under them, and there is no water damage at all on any part of the logic board that I can see. LCD and flex cable (and midframe) are all brand new, and I'd really like to get it working!
Somehow I dont think HTC will be willing to warranty this for me (tho I have replaced everything that had water damage, so it should be undetectable as there weren't any water stickers in the phone for some reason)
Thanks in advance!
well, after taking a long google walk, I decided to contact the manufacturer of the LCD I bought and try having them replace it for me. hopefully that is the issue and not one of the chips on the main board or some other cable i missed.
If it IS a chip on the board, I'd love for someone to point it out for me so I can try a reflow. Dont wanna reflow the whole board cus it's still got the internal stickers and I dont wanna damage them in case I can finagle a warranty replacement out of HTC
so does anyone have any other ideas what may be behind this issue other than the LCD? I dont want to have to wait to send this LCD back and get a new one, especially if the LCD isnt the problem
I'm not 100% sure about HTC phones as I have not opened one up yet, so i'll speak with my experience with BB phones instead.
When I was in the process of replacing the LCD screen of a BB Storm, there were 2 different types of LCD screen for one device. Perhaps this could be the case? In the BB case, there was a part number followed by either a 001 or 002, neither of which were compatible with each other. My assumption is a driver issue with the main board.
It's a small and simple thing to overlook, especially if you have prior experience in doing things like this, but I thought it would be worth noting. I would compare the old damaged part with the replacement part and make sure the part numbers match up. If the replacement LCD is from China or Hong Kong, I would be weary about their quality.
Regards.
well I got it on ebay, but it was a California seller. as far as I've been able to determine from looking at listings, the LCD's for HTC Desire Z and G2 are identical. All the clips match up right, and all the ribbon cables looked identical to the one I pulled. I'll look into checking on this a little more in-depth tho so thanks for the info!
Hey Bro,
did you managed to fix your phone? I just changed LCD twice, but still the same it boots and all but no video on it... You can even call it, answer everything else works but the screen... Im thinking to change the FLEX RIBBON CABLE, but after reading your thread not sure if thats going to fix my problem. With my original screen I had no backlight on the LCD with the replacement I got backlight on the LCD again...
Any suggestions, ideas welcome!

Need some help, dead digitizer or what??

Hey guys, I need some opinions about my problem, check my video http://www.youtube.com/watch?v=yeApacv5_gE&feature=youtu.be
I think it's digitizer fault but before buy new one I need to be at least 90% sure its digitizer, tried to load many roms, pds fix...
Anyone? Somebody must know
Well honestly it is hard to say without actually having your phone here. But you can almost be sure of this. It is most likely either the digitizer or the multi pin socket that the digitizer plugs into. I am working on one right now that went into a swimming pool and the socket is bad. It does the exact same thing as yours with any digitizer that I try. I'm currently looking for a way to remove the corrosion from the inside of that sucker. Gotta find some kind of spray. I can't seem to get it good enough with emery cloth or scraping... On the other hand I've replaced the digitizer and fixed this same issue on my sons Atrix.
In case you decide that you want to try to replace it here are 2 on Ebay that have the frame built in. Link1 Link2 So far I've bought 3 that were assembled this way and it is so much easier than buying a ditizer alone. No messing with double sided tape or worrying about backlight bleed.
Hope you can get some relief.
Dude, I've got the same in the same places! It have to be factory defect... there is too much digitizer problems...
Yes its very good smartphone but too much bad digitizers disqualify it, so JdgM3NT4L sometimes when I squeeze frame bottom of the screen works fine but only for few moments, so there are three options: need to replace adhesive sticker, replace digitizer and pin socket. Damn even if I want sell Atrix for parts I am not sure if all of them are fine
I used to get that a lot, phantom touches that make the phone useless until I turn the screen off and back on.
Cannot say for sure but when I stopped using alcohol wipes to clean the screen and reduced the amount of static it was exposed to (keeping it polyester pant pockets seemed to make it worse believe it or not!), it seemed to pretty much stop.. now I've gone months without the issue.

Well, the socket is on the motherboard, so no replacing that... For 30 bucks, I would try the digitizer. I should have explained the part about water damage. That's one of the few ways that the socket would have been damaged. That's kind of what I was eluding to when I mentioned not having your phone here. If I had it here I would know the history and whether or not it had water damage, etc. My apologies for not being more clear about that. I just don't want you to buy the digitizer and then be upset because I told you to leap right in. In my humble opinion. A new one will probably take care of the problem. 90% if I had to call it.
I wish you the best of luck. And if you have any problems installing it shoot me a pm and I'll be glad to Skype or email to help you get through it.
Thanks, my Atrix never saw water. I just dissasembly phone for every single part and cleaned all socket with alcohol. Put back together but no result. I'll try replace digitizer with frame from ebay, it's risky but hope it will solve the problem.
Its the digitizer I'm 99 percent sure I had an identical problem. Dead zones and the phantom touches. Replaced the digitizer and problem solved. I believe the digitzer design is bad for our phone and is prone to this kind of failure

[Q] A Bit of Help please! S4 Wont Turn On

Hello,
Unfortunately, I am in possession of a Galaxy S4 I9505 which has been dropped into water. It doesn't show any signs of live except a single vibrate after around 6 seconds of holding down the power button. Drying the device in rice hadn't helped, so I upped the ante and submerged the motherboard of the phone in ethanol as per the instructions of a revive-a-phone kit and left to dry for some time. After this it still didn't work, so I assumed that the motherboard was simply too damaged.
I had managed to buy another used phone (working, but with a smashed digitiser) and swapped over the motherboard from that one onto the new. Unfortunately though, it still doesn't work. I have disconnected all of the connections to the motherboard (the externals that is, camera etc) with the exception of the video cable and it still does the same thing.
Is there anything I am missing? Or does it look like the LCD is at fault? If so, would it be in any way possible to exchange the LCD without replacing the digitizer too?
I am sorry for the drawn out question, but any help would be very much appreciated!

AFAIK, digitizer is connected with LCD by some glue...
However, putting the phone into ethanol itself could potentially kill the phone, as it is a good solvent for any acrylic based paints, isolations etc...

I think the idea of it is that it will dissolve any deposits from the water that might be left on the motherboard. I had used it to some success on another phone, but no luck this time. In any case, it was only the motherboard that was submerged, not the entire phone as the guides would suggest, so that couldn't be the problem.
Agh, I see what you mean. I have gotten time to view some videos and it seems it is neigh on impossible to remove the screen from the digitizer. I bought a second phone with the only piece I needed being broken!
