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!!!

My Hermes has been suffering from screen whitening for couple of weeks, when it one day stayed all white. I've taken apart my Hermes and reconnected all connectors I've seen, including D-Pad connector, tightening and loosening the screws. Nothing worked... What should I buy? Do you think that the actual screen may be faulty? Or maybe the flex is damaged and I should buy it?

I have been reluctant to answer this, because there is no guaranteed answer. You have tested and reset the connector, but did you try placing some padding on the d-pad chip - to push it more firmly against the d-pad board. It has been quite successful for some members here. It is thought that a common cause of the white screen is a poor connection on the chip.
You could try getting a new d-pad board or a part from a second hand device that does not suffer from the white screen problem. If you know someone with the correct equipment you could also try re-flowing the solder on the board.
But I would say that a new board is not guaranteed to solve the problem as it is still possible that the flex cable may be faulty (or it's connector.

First of all, thanks for answer.
Yes, I've tried pushing it harder. Also I unpluged D-Pad and tried to turn on- still white screen. Unfortunately, I don't have access to any spare parts of this phone.
I bought Flex cable on ebay and IT WORKED!!! Yay, but now I'm experiencing some problems with usb connection
Hey,
i got the typical problem that my screen wasnt responding after use of endbutton. Sometimes it was working.
I now disassembled the device and saw that the flatcable had a small scratch and i guess the first one or two cables are brocken already and only get contact sometimes by luck.
So does anybody know if there is a way to repair this ?
A new touchscreen isnt to expensive 20-30€ but why throw away a working one if a cable is repairable easily?
Next time i will glue the cable to the display so that there is no flexing when pressing the endbutton. The problem is that there is a little space between that is pushed away each use of the endbutton and someday the problem occours.
Hi,
I had to replace my touch screen to solve the same issue
Is there any thing we can do to prevent the same damage to the new screen ?
Thanks
Well i tried a few times to fix the issue.
But its hard to solder the flex cable without totally burning it.
If i solder it its very likely to break fast again.
Im going to buy a new digitizer too..
To your question:
Yeah i saw that there space between the flex cable and display. The cable is bent a bit towards the buttons. When you push the button the cable is bent back in the free space.
I will glue the flex cable directly to the display and put a layer of protective tape over it. so it wont bent (What causes our error) and wont scratch(if this could happen too).
The problem is the poor quality of the flex cable. Its very hard and therefore breaks easily what causes the wires to break to sooner or later.
If i can ill try to take a few photos but its hard as my digicam cant focus so closely..
Hello,
I recently changed the LCD and Digitizer screen of my HD2, but while disassembling it I half cut the flex cable for the buttons, while trying to take it out. It's not completely cut, its about 1 mm cut, but non of the buttons are working. Is there a way to fix that without replacing it, or i have to replace it and is there different type of buttons cables for the EU and US versions, and will this work http://www.ebay.com/itm/New-Keypad-...887?pt=LH_DefaultDomain_0&hash=item43af09e827
Thank you!
Not so good news

You have no other choice than replacing it...
There are no differences for keypad flex between EU/US version.
You *could* scratch the enamel and reveal the tracings underneath, and then bridge the gap with solder, and then wrap it with thermal tape or similar..
I have never had that happen to me during all the times I had to disassemble my hd2s to replace the digitizer but this is what I would have done.

Yeah, you could do this, but then you should prepair yourself to disassemble your device sooner than you've been expected!
In other words I wouldn't recommend this to someone who doesn't disassemble his hd2 every month(even week)!
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 :-/

how did they break? i'm going to attempt this myself soon and would appreciate any advice on getting the clips open safely.
Hello
I can't charge my LG G2 D802, so I ordered a charging flex cablefrom ebay.
After replaced, the phone charges well, but the screen is almost unresponsive.
And it's very interesting, because if I replace to the old one, everything is the same, almost unresponsive screen, not like before disassembly...
Any idea what to do?
Connectors and everything looks fine, but I can't believe touch screen stop working after disassembly.
Please help if You could...
Thank You!
You disassembled the phone? If you didn't put all the components back in place as it comes from factory and taped, then there could be grounding issues. There is a set of transistors next to the lcd connector and above the charging port, make sure it's touching the golden pad on bottom and is taped.
Or else it's a bad cable, bad grounding somehow, moisture issues etc etc.
I think You're right.
The set of transistors may not connecting well.
Can I use processor pasta to glue it back?
Or just some simple tape from above?
-----------------------------------------------------------
So I cleaned it with alcohol and the original glue getting stronger, so I put it back to the right place and put some tape on it.
But still the same.
Do I have to put tape on the cables above the battery?
How could I find where is the bad grounding?

No i don't recommend to put thermal paste therez if it conductive it can short nearby components and can also get messy, it is only for using on chips. I suggest you use double sided tape, but do it strategically so that it leaves a small portion open for the golden pad to make contact. And after that you put nonconductive tape on top of that. Make sure the metal part of the white cable nearby is not touching this area, or you can also put tape between them. I suggest to put tape on the lcd connector as well.
Whenever this problem arises, and if you have trouble to fix it, an easy way is to disconnect and reconnect the battery after a few seconds, should work ok.
You can also purchase a new one like this, look for your device model - https://m.ebay.com/itm/183023879505

Seems like the set of transistors well connected now and I put tapes on it and on the screen connector as well.
And I reconnected the battery too, but nothing happened.
It's the same as before.
And if I replace the charging port flex cable to the old one, it's the same too, but before disassembly it works, but the problem was I cannot charge the phone.
Any other idea what should I do to fix it?
I cannot choose D802 on the link You gave me...
Anyway I think this one and the old one is fine if it's about the touch screen, have to be something another...
