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!

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...

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.
A customer of ours was working outside and left his 8525 on him. It has moisture damage (the sticker is barely a splotchy red). Me and the boss fiddled around and found the battery was shot and the screen turns white.
We replaced the battery and ordered a replacement screen (off Ebay). We used the disassembly instructions and replaced out the screen, but the screen is still white. You can barely see anything on the screen. Just wondering if there is anything someone could suggest looking at. Since it's only 2 months old I figured we could try to fix it. Hell, we just love taking stuff apart mostly.
There are va few threads on "white screen", but unfortunately it's a problem that has no one fix that I've heard about that works for everyone.
Some of the related things folks have thought were related to it include:
D-Pad problems - either the 2 screw connector or components on that board. Might well be that moisture entered there of course?
One report said the screen came back when pressing a chip on the m/board - but this may have been a one off issue for that person.
Some have reported that the various flatcable connectors should be checked. Some appear to be inserted correctly but may not be fully in.
Unfortunately, current advice here seems to be to get an expensive repair - that might well include the mother board OR a second hand device that might well be cheaper than repair. The device can have a considerable value if parted out under e-bay.
Mike
Thanks for the misc. info. I will go ahead and disassemble it and try those one by one and see if I can get it going.
As far as moisture, I'm not sure how bad it could have been damaged, if at all. You can look at the white sticker and it is ever so barely red, and only in a couple little spots.
It's not like I can break it right???
There was some talk about the buttons on the HD2 going bad due to much use on android ROM. Was wondering if Evo digitizer will fit/work on HD2? That would get rid of the possibility of buttons going bad.
To engineer that would be SIGNIFICANTLY harder than just buying the part for the buttons on the HD2 and installing it. Phone parts are not interchangable and if you've ever opened one up you would know the answer to your own question. The talk about button problems on the HD2 is over exaggerated. First you don't know what the people are doing that are starting those discussions - how hard are they with their phones, etc. The keys in most phones are pressure contact switches - they are designed to perform for years of normal use not used by a gorilla or someone who isn't exercisiing care.
I've owned HTC phones like the TYTN I for a number of years and used the hard keys - very similar contact switches - never a problem. The same for the 2125 which was a Windows phone with hard keys only. They were very small and I used the phone for two years every day. Keys did not wear out and they felt about the same as when I bought it.
Don't worry about it for at least two years of general use. Even when using Android you can get widgets that mimic soft keys (ie. the back/windows key).
Stim, thanks for your thoughts. I purchased a HD2 with a broken digitizer and replaced it so was wondering if the digitizer on the EVO would work since they are the same size. I did get a chance yesterday to see a pic on the internet for the EVO digitizer and the ribbon on the EVO for the capacitive buttons and digitizer does not look compatible size wise on the HD2.
I've never had buttons go out on any of my phones before. With all the talk of the buttons going bad I thought maybe it was a quality issue with the HD2.

I might be completely stupid here, but what does the screen/digitizer have to do with hardware buttons?
I thought the digitizer is just the touch sensor of the screen, and that the hardware buttons have their own button pads/switches (whatever they're called).
Now, if you were talking about capacitive "hardware" buttons (such as the ones found on many Android devices, like the Nexus1), I can see how the digitizer would come into play.
while on subject of digitizer of hd2, does anyone know how to replace it?
I recently dropped my phone on the ground and even though i had a scratch resistant film over it i broke the glass digitizer, phone digitizer work 100 fine but i would like to replace it, honestly i got lucky that i did not damage the lcd screen under the digitizer, i have priced replace ment part at about 60 with tools to fix it, i would just like advise to get repairs done
Actually you aren't so lucky. There are plenty of threads on this issue. Replacing the digitizer and lcd as separate components is nearly impossible without damaging the lcd. Hate to be the bearer of bad news. Separating the glass from the LCD is nearly impossible. They are glued together and air sealed. Some have tried and failed by either destroying the lcd or making the phone inoperable. HTC either heat seals the two together or uses a special adhesive. In either case unless you are working in a class clean room (no dust) getting specs, skin or hair more than likely and you will be really ticked off to find that crap in there when you go and turn the phone on. Mike Channon's website used to post official (semi) HTC maintenance guides but the HD2 hasn't been posted. There are however a couple of Russian links that go through the process. The HTC guides were much better and they listed the steps, torx settings, oven temps etc..
I've seen a few on eBay - new but there seems to be some that need to be soldered and others that don't.
My suggestion is buy a complete unit if you have to or sell it damaged on eBay and get another phone.
i can also buy a lcd and digitizer together to eliminate the hassel of having to seperate them, and install componients like that, only downer is prices avererage 100-120 dollars, would that be a good option? i have seen videos on youtube on how to go about replacement, im quite knowledgeable about wire work and sodering but do u think im getting in over my head by tring to do this repair?
i know buying a used hd2 is about 575 and it only goes up from there, i just dont have that kind of cash right now, plus my phone is unlocked, has hard spl, running nand android flashed directly to phone, with att service fully working, something very few owners have accomplished with there hd2's..

I notice the hardware buttons are not included. My phone is fine except the hardware buttons were scratched up after suffering a hard fall.
I don't know. I've done complete overhauls on TYTN I and TYTN II's. They didn't require heating to remove the panels - they just snapped in. Phones were very modular no work involved except screw removal. The latest phones seem to be held together with some sort of adhesive. I remember looking at how to disassemble a FUZE. Major pain to remove the screen from the keypad - required an oven to melt the glue.
Look for a complete quide that shows step by step disassembly AND assembly. Sometimes they forget the tricks to put it back together and you get messed up.
The 150 for the housing seems a little steep. But most of the LCD/DIGITIZERS are at least 100. Be careful about some of the parts they are stripped from a "working" phone - doubt it - why would someone take a perfectly good phone and break it apart for the parts? Doesn't make sense - they can get more money for the complete unit. Sounds like they were defects or seconds - screens may have dead pixels or spots. I'd look for factory fresh new stuff personally. You can buy the keypad/keys separately on eBay for next to nothing.

The digitizer is the glass that you touch when operating the phone. The LCD panel is the part that shows the pictures. The digitizer covers the LCD and both are sealed together. The TYTN series of phones did not have this.
The OP was concerned about replacing the digitizer without harming the LCD. I know from experience that this is very hard to do. I managed to get them apart and replaced the digitizer on my HD2, only to damage a single line in the LCD when I re-assembled the phone. It was a complete waste of time and money.

Actually, the housings sold 3rd party are usually factory fresh, unless specified otherwise. HTC expects to have techs replace various parts of the phones and ordered a certain percentage of these types of parts. When the initial sell drive dies down, the excess is unloaded to 3rd parties who either offer them up on sites like eBay or catalog them for companies that repair phones.
well like i was saying would it be easyer to buy both the digitizer and lcd already together and just replace the ones in my phone?
Hi
My friend has cracked the screen on her uk wildfire, i have replaced screens before so i have offered to have a go. However it appears that there are 2 different types of screens one with a chip (or IC) on the ribbon cable and one without. Does anyone know which one I need to order? the phone is still usable so i dont really want to take it apart just to find out what is already in it.
Also can anyone point me towards any tutorials on taking these apart?
Cheers
Jim
You'll have to take your phone apart to see which one it is just look for a chip on the digitizer ribbon cable if there's one the you need one with ic.
If the lcd is broke you don't need to they are all the same

Excellent thanks for the confirmation and the link
Tonight I came home and turned on my phone just to find the screen is potentially broken.
Everything else works fine except the screen. Whenever I press the power button it gives me a black screen with a few lines on it. If I smack it a little then the lines change.
I'm wondering if it's just a lose ribbon cable or the screen is actually going bad.
I'd take it apart but I don't have the tools for it but if it's still as simple as that then tomorrow I'll just go buy a screw driver

OK 1st the LCD (and the digitiser incidentally) are not jaw & ribbon connectors but are pop connectors.
Look in the youtube i posted below.
I have had considerable experience digging around inside Desire Z's. In all honesty unless you dropped your phone its more than likely your LCD is fubared
Even if you did drop it its probably fubared ..... your starting to get the theme eh??
Whatever your LCD is probably fubared
However the good news is the Desire Z is the easiest phone I have ever dismantled/reassembled, as it is mostly held together by lots of high quality screws, so you don't need to take risks and get frustrated levering bits around to try and remove them.
Also LCDs are easily obtained and cheap.
Check this basic disassembly guide its the best i know.

This one below is stills only no vid, but it shows some small parts steps to in the above, defo 2nd best unless you want to remove small components
http://www.youtube.com/watch?v=SliyuYBvfic&list=PLEBB8603769CE1417&index=14
Oh yeah since you need to completely strip the Desire Z to replace LCD.
You may as well do something about that pesky weak hinge spring whilst you have it in bits.
This is a VERY worthwhile mod it takes 2 mins and transforms the keyboard hinge mechanism.
If you can't be bothered buying an upgraded spring (which is actually WELL WORTH IT) then you can just stretch the old spring and replace it to get a good result, just not as good as the upgraded spring.

Just be slow and careful, better it takes 2 hours to do a 10min job than 15mins and a busted smartphone component.
Hope this helps bro

hi, well, being the most unlucky person in the world, i too have had plenty of experiance dissmanteling the desire z. been through two phones, changed 2 digitizers, 2 LCDs, and now i have a broken flex ribbon cable (i know this for certain). i ordered the only one, as far as i can see, in the uk, which turned out to cause the phone to overheat when the screen was on. typical. sent it back, but the idiot sold the only other one he had to someone else when he knew i needed a replacement! sooo, without wanting to hijack this thread, does anyone know where i can source one it the uk? (the complete flex ribbon cable and hinge mechanism, as just the ribbon cable would be very tough to replace on its own without damaging something) many thanks..
