I recently dropped my MDA Pro and smashed the screen. Well, all the pixels still work, as does the touch sensitivity, but the backlight only works on maybe 60% of the pixels. ie, with the backlight off (in bright sunlight) there's no apparent damage. Is this a total screen replacement job or might there be a pikier remedy?
It sounds like hardware damage. A software most likely will not be able to help.
I'm in no doubt that it's hardware damage, but being utterly ignorant (or worse: partially ignorant, a little knowledge is a dangerous thing) as to how LCDs work, I was wondering if it could be fixed without having to replace the whole screen. ie, as I see it, the screen consists of the LCD (the pixels), the backlight and the passive touch sensitivity system. Well, it's only the backlight (the simplest of the three?) that's faulty. Or should I retire the old MDA Pro to being the handset I take to the beach (instead of the SPV) or use it as a wifi webcam or some sort of server?

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.

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!!!
well my htc hd2 is using android and using it a year by now and notice that the upper left of the screen is not working?is it the lcd or digitizer or just need to align it?i dropped this many times(up to 5 times i think)but no damage on the housing and it looks new,and it is annoying in some games cause it wont work and i notice a very little red dot on that part.....pls help
If you lost sensitivity and the screen does not respond to touch, then it's a digitizer, if picture is distorted or, as you describe, a red dot appeared where it shouldn't be - LCD, sounds like both in your case. I am not quite sure how it doesn't work in games or whether the problem is present in normal screens. Alignment is a procedure to tune and correct mistakes in touch recognition or to make touch more precise on resistive screens.
I suggest replacement of your LCD + DIGITIZER. Dropping it many times may have caused it too, even if housing looks perfect.
Hi,
Sliding out keyboard causes pressure marks on screen (attached video). Is it dangerous? I noticed this some time after getting back my phone from the waranty service, they replaced front panel and lcd flex. Can it be reason of this issue?

The max damage you can cause to your device is, in my opinion, some dead pixels, but no, this is not the regular behavior of the MS2 slider keyboard
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.
