Hello everybody!
I saw an auction with a Toch dual, "broken display". I thought to buy it, and switch the LCD with a new one. I paid the touch just 30$ (20 Euros).
But the situation was a bit different: the device is fall into the water (i see the pink marks on the device and the battery), the display was actually ok but has problem with the backlight.
The backlit was veeeery soft, didn't react if i tried to set it manually on higher levels, and was a bit stronger if i open the slide of the cell phone.
I thought, it could be a problem of humidity, and if i dismounted and dried the electronics, it would disappear, as it was with my xperia x1: felt into the water, some humidity inside was causing the backlight to flash and disappear, once dried everything got normally.
So I tried, but actually the situation now is even worse: the digitizer does not respond at all, and no changes in the light.
So my question is: can i just buy on ebay a new LCD + digitizer, and solve all the problems? I already changed a LCD without digitizer on a cell phone, and it worked. I don't know, how hard and risky can be to change also the digitizer, and also i cannot imagine how to fix the backlight problem, just suppose that with the new LCD it will work - it is integrated, isn't it?
Many many thanks for your help!!!

A few months ago the screen on my SPV M600 took a knock which cracked it pretty badly, to the point it couldn't be used. I've rebuilt two other HTC phones in the past so felt fairly happy buying and fitting a replacement screen myself, along with the fact Orange wanted well over £100 for repairing it!
I dismantled the phone back to the screen to find it had a gold LCD cable and bought a new one on eBay.
I've now tried fitting the screen which works perfectly when the phone is still appart, but when I put the casing back together the screen goes blank. The exact point it happens is when I'm clipping the side of the phone with the volume control into place. The screen gets very bright as if the backlight is either getting too much power from somewhere or the backlight setting isn't taking effect. If I set the backlight to minimum it's most noticable as it goes from dull to full brightness when I apply pressure between the screen and board on that side of the phone.
I've tried sliding a piece of card between the screen and board to see if there was something touching that shouldn't be, but it doesn't seem to make much difference.
If anyone could offer me any advice on how to solve this I'd appreciate it.
Thanks.
I think I've solved it, I hadn't put a layer of the copper from the back of the old LCD onto the new one. It seems to be working fine now.
Hi guys, I need some help here. I literally threw my wizard out of the window shaking out my bedsheets and it dropped three stories into the backyard.
When I turned it on again (the drop had opened the battery case), at first the screen was bright white, then turned darker and darker showing some sort of noisy stripes (static, not moving). When it goes into standby and is turned on again from there it does the same thing.
some facts:
- there is no visible crack in the display (neither from the side, I disassembled it)
- all buttons and the touchscreen are still responding (u can see that because the background lighting responds to them)
- the wizard is still accessible via usb
- I don't know whether the phone still works because I can't enter the pin w/o display.
It seems strange to me that the display should stop working while the touchscreen and the background lighting remain unhurt. I am thinking about replacing the display (only available together w/ the touchscreen and bg-lighting), but I am afraid that it might rather be a problem with the communication between the main unit and the display, even though there was no visible damage there.
Does anybody have experiences with that kind of behavior of the display?
Is the display that vulnerable that it breaks before the rest (light, touchscreen)?
I didn't find any cases similar to mine in the forum. If there are and my questions would be answered there, please direct me there.
Thanks for the help

Try taking it apart, the force of inpact could have made a connection loose.
Disassembling I disconnected everything possible. Next thing would be to take apart the display/bglight/tscreen.
did you mean that? looks pretty fragile to me...
thx
yeah, I wouldnt mess with the display .. lol .. I meant a connection somewhere inside the device... like a loose ribbon or something
Yeah, seems hopeless. Guess I'll have to buy a new display and hope it works :-(
I'll post again once I got some results...
Problem solved
For the archive:
I exchanged the display and apparently only the screen was broken and the rest was unharmed.
I'd also like to add that two days ago (1 week after I repaired the thing) I dropped a plastic bottle on the phone in such a stupid angle that it broke the touchscreen. the next thing I will report here is whether it is possible to exchange the touchscreen only by doing some soldering.

Hi,
Recently ive repaired a HTC Universal, put it back together as best as i could.
Now when i do touch the screen with a stylus, the screen has funny colours behind it. It kind of like when you touch/ prod your Computer LCD. It only happens when theres pressure on the screen so its not really a huge problem. The touch screen is definately there cause when i tap the screen it responds (e.g i tap start and the menu pops down).
If its normal then i can take it, but if its not im complaining to the ebay seller.
This doesent happen when i put any form of pressure on my HTC magician LCD, so im curious.
Let me know what happens with your universal
Cheers,
Whitemoo.
This is not normal behaviour of any touchscreen device!!
hmmm... well i just looked at the broken lcd screen, and even though the LCD itself is shattered, the touch screen is in perfect nick.
I put pressure on the touch screen and couldnt see any of the symptoms i saw on my current LCD
You guys recon i should swap the touch screen over? either way im complaining to the sellers, DODGY.
whitemoo.
from my knowledge, im pretty sure its normal. it happens sometimes on my 9000 so yeahh....
This is my first post here and though i read similar posts on this subject i would
like to read your opinions on this one.
I accidentally dropped some water on my touch hd and my display got damaged.The phone worked fine and so did the digitizer but the problem was that the backlight of the display was dead.At some point the backlight turned on but when i tried to input the unlock code it turned off right away (did this several times).I knew that i should replace the lcd (and the digitizer just in case).
I bought the lcd and the digitizer seperately and i managed to assemble the phone back using the service manual.Since then when i turn the phone on I hear the starting sound,i get the vibration then after a while the screen with no backlight again displays the "tap here to configure your phone" screen (after the hard reset),when i tap i get no response.
I checked the connections many times and i also used a second digitizer with no success.
Is there a possibility flashing a new ROM will solve the problem?
If so is there a way of flashing a ROM when the phone's screen is not usable?
Waiting for your precious opinions/suggestions/knowledge
Thanks in advance.
Hello,
Flashing the ROM won't solve an obviously hardware problem.
If you changed the LCD and still have no backlight, then either you bought a defective screen, or the problem is elsewhere, maybe on the main electronic board... Which would be bad news.
BTW, I wanted to change the digitizer in the apst years, but its not provided with the glue, so I had to buy a whole assembled screen + digitizer.
How did you manage to glue the digitizer on the screen ?
I aligned the screen with the digitizer and then i used small pieces of a special thin and trasparent tape to hold it in place.The tape holds the screen tight and it is barely visible, it also has the advantage that you can seperate the lcd and digitizer anytime you want with ease (though you have to be very delicate when applying it to get a good result)
I asked for a replacement of the defective lcd and i hope i will get a new one.
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.
