Issue Replacing G1 Touch Digitizer

Hi.
Does anyone has been had this problem by replacing a digitizer to a G1:
I bought a newone digitizer for my HTC G1, after replace it and assamble it, the digitizer did workd at all. I retryed a lot of times and nothing. I test digitizer on another device and it worked fine. flex and cables were tested and all goods.
Any idea? any help?
Thanks.

Somebody having the same issue?

I have made that mistate before but if you know how to this this already just ignore what I say,
Check to make sure you connected the ribbons to the connectors correctly. There is a tiny little lever that is the lengh of the connector located behind the slot at which the ribbon inserts to.it should lift up and down, use your nails or a little toothpick. You must lift this lever to release the pressure on the ribbon cable in order to detach it. When re-attaching it, ensure that the lever is in the up position, then lock the little lever down after you insert the cable. Hope that helps. And remember be careful with the ribbons because if it rips just a little bit it wil cut the circuit.

Solved!!!

I just found this fail in motherboard.
It was due to a rised pin at the cable connector. After a deep clean and apply my hotgun, Done!!!

[Q] Replace buttons without removing main board? Or change wake button?

Is there any way to get to the buttons on the front without having to remove the main board? I just broke my cable to the buttons and I am planning on replacing it soon.
EDIT: Is there any app that will let me remap the key that is used to wake up my phone? I want to be able to use the phone while I wait for the flex cable to show up. I can turn my phone on by plugging it in because it is on MAGLDR.

No, you will have to completely disassemble the phone, including the lcd/digitizer assembly from the middle chassis to access the buttons flex.

Maybe a stupid question that also refers to this but I got conned by a guy whom I bought a HD2 from. Also the cable to the buttons is broken, as so many other things.
Does your touchscreen still react when that cable is not attached?

Yeah the touchscreen still reacts without the buttons flex cable attached, done it myself a bunch of times, so 100% confirmed

Ok thx for confirmation. This guy conned me with a 'perfect hd2' broken camera glass, broken flex cables all around, a broken digitizer, .... well nothing worth then

Darn it. Do I also have to remove the main board from the chassis too or is there any way to remove the screen and digitizer assembly from the chassis without removing the main board?

You do not have to remove the entire LCD/digitizer assembly, you just need to pry enough space between the bottom of the digitizer and the plastic frame to remove/replace the buttons. I've done it to three phones. It may be easier in the end to remove the entire thing, because it can be difficult to get the part that you pry up to adhere back together though. This phone is a major pain in the ass to work on beyond the motherboard area.

Hmm. Would heating it up a little bit make it easier to pry apart then? I tried it a bit after I realized that I broke the cable, but my device seemed to be really stiff.
And if I do remove the screen, would I need anything special to put the display back on?

Yes, you have to heat it up or you will probably destroy the phone. The best thing you can do is get it very hot (not hot enough to melt the plastic button strip) and try to get the adhesive to stay completely on the frame, then reheat it again right before you put it back together. I repair phones (and game consoles) for a living, and heating the adhesive (right) before assembly is the best piece of advice I can give anyone on just about any phone. Most of the time you don't even have to replace the adhesive if you do it this way.

Is changing hardware button for power on HD2 easy

Hi,
My HD2's power button died recently. It doesn't do anything when pressed
I've been using button savior software to have a soft key for end button for day to day usage, but however I can't get into MAGLDR to flash new roms anymore
So, I decided to order HD2 flex board from amazon as it costs only $15.
http://www.amazon.com/HTC-Keypad-Fl...OSAO/ref=sr_1_1?ie=UTF8&qid=1320870170&sr=8-1
I have some experience opening up things and fixing them prior and also have the required screwdrivers with me. I've checked out some guides at ifixit for hd2, it seems easy enough to open, however they don't have guide to change the buttons.
I want to know if anybody has changed these buttons (the flex cable), is it easy enough to do by yourself or should I goto a professional repair guy to install it ?

No One :O
Well I got the flex board...I will try changing it tonight

Its not so hard but be very very careful ... or you soon buy new digitizer too. You must detach middle chasis at digitizer. Did you have 3M special tape on hand? When you go place back digitizer to middle chasis then you need before that replace all old tapes.

I dont have the tape...can you give me any link for it ?
EDIT: I also was studying the guide on iFixit for HD2
http://www.ifixit.com/Guide/Installing-HTC-HD2-PB81120-Logic-Board/5919/7
I don't see the flex board for the keys visible till step 21..is it after removing the logic board I would be able to change the keys ?
It sounding more complicated than I thought

Unfortunately this guide what you gived is not complete. It for very basic works and for beginners. But thanks about link.
This is not only one place for tape but: 8mm and 6mm. These are right tapes, but i didnty find right now 3mm and 5 mm.
Yes, its after removing logic borad and then detaching middle case at digitizer with lcd. Look this good official apart video. Its good for learning to take apart hd2 correctly. Your interesting part starts at 5.28. YES RIGHT, YOU MUST PUT MIDDLECHASIS WITH LCD AND DIGITIZER TO OWEN! It just for that that then you can detach middle case at digitizer with lcd easy and not broke something (specially digitizer).
Have good time and later enjoy fixed hd2!

LG touch sensitive buttons dont work

Hello everyone
I have this problem with my phone which is a LG GW620 it has touch sensitive home and back buttons and i recently had to replace the flex cable of this device becouse i broke it. The original flex cable had these foams glued like this:
deltamobile.lv/published/publicdata/DELTA1DELTA/attachments/SC/products_pictures/SLP_553_l.jpg
and the one i bought did not have them:
bridgat.com/files/LG_GW620_Flex_Cable.jpg
so now i need your help on what i should do with thease to make the touch sensitive buttons work again becouse without thease foams the buttons dont work.
Sorry for my bad English i hope you will understand what im trying to say here
EDIT: I attached the files with marked areas of touch sensitive buttons and where thease foams are.

Could you mark these foams on photos?
If you mean regular rubbers used to keep things in phone on place - I'd take old ones from old flex and stick them to the new flex.

Yes, what Rebellos said.
The flex circuit board just has the contacts.
The rubber button has a carbon pad on the inside that shorts the contacts.

ok well the flex cable came with those carbonpads so how do i atach the foam to those carbon pads?

Sorry, I don't know what you mean by "foam" vs. the rubber button.
Do you have a more detailed photo?
You should have enough pieces from the old setup.
Can't you figure out how to merge the old and the new?

there is no button on the phone its touch sensitive mayebey it detects heat or something but with the new flex cable it doesnt do that any more.

Hit some problems during screen replacement

Just bought a new screen for a cracked hd2 and hit some problems. Firstly, its a uk hd2, so it was a solder connection, i bought the screen + digi from ebay and noticed it was a ribbon connection (not sure if that will make a difference). When undoing these plastic clips
http://imgur.com/Faiyig3
Both broke. They were so brittle, has anybody seen/heard of a way to fix this? I put it all back together and the screen does come on, but touch doesnt work.
Can anybody tell me what these cables do? Is one for touch, what about the other?
Gutted about my hd2, its been going so well all these years...is it fixable?

Not good :-/
those 2 clips: one is the flex ribbon connector & other is the LCD ribbon connector.
The ribbon from LCD also is feed for digitizer.
Not sure if the locking arms are replaceable by themselves ! will look at an old mainboard & see.
you may get some function by bending a very light V in the ribbon so point of v is ribbon contact face & thus pushes tighter in socket promoting better contact.
putting a bit of tape on back may help too! be careful though as actual socket is very fragile too ...

Tell me about it, thanks for explaining what the ribbon connectors do...I couldn't understand why the screen would turn on if the connector was broke. That's a good idea about slightly bending the cable, I will try that tomorrow afternoon. If i could swap them out, that would be awesome.
Thanks for answering, I appreciate you talking time to help a fellow hd2 fan!

Have made none working digitizer work via creating very light v shape bend in middle of contact area (bending across width of cable)
Do be gentle though ... not sure how successful it will be without clamp though :-/
