I have already used these methods
is the new screen ok
are you sure that your new screen isn't broken too.
I think that it's not the screen, although the phone to vibrate a few times
disconnect digitizer ribbon and see if lcd turns on.

Hi,
The touch screen of my HTC elf doesn't work anymore.
I am going to order some parts to change the digitizer myself and also the casing to make it look a little newer.
Anyway, I'd like to understand how the touch functionality works exactly. Is it a pressure on the digitizer itself that make a "touch" or is it a pressure on the digitizer that press the screen and this action make a "touch" ?
When I power my disassemble Elf, a pressure on the screen itself doesn't do anything....
I'd like to know if I need to order a screen as well
Hi,
just replaced my own elf's digitizer a month ago... and the phone is like new.
To answer your question it's the digitizer that reads pressure and sends the data to the system (if you already disassembled it you should have noticed a flat cable that connects the digitizer to the board).
So if the screen on your elf is working you should solve the problem by replacing only the digitizer.
You rock, I order now

To clarify. It is your LCD that is broken, your digitiser may well be but as you can not see to test...
One way would be to hook it up to your pc, run mymobile, and see if pressing the digitiser registers the command when viewing it on mymobile.

thnx for the reply .......it does give a responce when i touch the screen ....i mean the lcd brightens up....!!! btw what is digitilizer..???
Digitizer is the thin screen above the LCD screen which recognises the stylus/finger touch (Analog) input into Digital Signals.
Hi my friend gave me her HTC wildfire to fix the digitiser as another friend dropped the phone in olive oil and well oil doesn't go well with the capacitive screen.
While trying to clean the capacitive part (which failed I'm going to have to buy a new screen) I managed to break the connector going to the front buttons the small ribbon cable the opposite side of the display and capacitive cable attachments.
So my question what does this cable do I assume that this only powers the lights behind them or does it also run the buttons?
Thanks.
It's just the lights, I broke mine when fitting a new screen. The buttons still work i just have no backlight.

Thanks that's what I thought, the buttons still work on occasion and are part of the capacitive screen.
Well to fix the screen now.
Thanks for your reply.
So my friend got huawei X5 U8800, it had shattered screen which worked fine. So he bought new screen (I think it's called digitizer, the LCD itself was intact) and installed it. Now only the soft buttons work. Is there something that could cause that? Apparently there was only one ribbon cable to connect.
Sorry if I'm missing something obvious.
If the soft buttons work, the problem might be in the digitizer, as the soft keys are actually just extended touch screen. So it might be a faulty digitizer. And there is only one ribbon cable on the digitizer connected to motherboard.

Thanks for your input. I'm not very familiar with these screen replacements (never had to do one). So can I assume that it should work like "plug and play"? If that the case then I assume that the phone itself has some problems of it own or the digitizer is faulty like you said.
Also sry for my english, not my native language etc.
Hi
I've dropped my HD2. Everything is working, including touch screen, I can unlock the phone, I can answer the call, but screen is black, not broken.
What should I do? Does the lcd screen replacement will be sufficient? In that case, could the screen be ok, but some other display "processor" could be dead? I'm asking because I'll try to this on my own.
Could simply be the lcd cable has slipped slightly but probably more likely an LCD replacement needed.
You need remove rear housing & have a look & make a decision from your findings/testing.
hello
I've got a little update - lcd screen is working well - I mean it displays the image, the only malfunction is backlit. Right now when i use flashlign I can actually see whats on screen. Do you have experience or think that backlit connection can be repaired? Do You have any schematics for hd2' lcd ?
I suspect new LCD required by sounds of it. LCD can not be stripped for repair so after basic inspection of external connection replacement is only solution & not expensive due to falling cost of HD2 parts.
