Hi,
I had the following problem with my HTC Diamond 2 (it might have got wet & it might possibly have had too much pressure on the screen)
Problem:
The mobile boots ok and the normal buttons at the bottom work fine, as do the volume up/down buttons. The display, however, has what looks like the newton rings and when I press the display it detects a 'press' about 1cm to the left of where i pressed. This means I can't use the right hand side of the display and also can't enter my pin.
Error Diagnosis: (from Arvato Services in Germany)
Mainboard is defect. Cost to repair = € 303.17
Is this possible ? If there was a problem with the mainboard then I would expect to see other problems - and at present, I can only see that the touchscreen has a problem.
Please let me know what you think, thanks in advance !
(ps there should be a question mark at the end of the 'title', don't seem to be able to edit though)
Based on your description and from what I've read, it's definitely the digitizer.
It is possible that you have a damaged board, but regardless, your digitizer is bad.
I would attempt to replace this yourrself then see if everything is fine before sending it to repair.
I had the same problem!
The screen was getting worse in alignment over a time frame of a couple of days. If replaced the digitizer and screen and all is back to normal ..... however it seems to work better then ever before.
The only problem left is dust between the digitizer and my screen, but this is my own fault since I didn't glued the screens. I'll re-open in the next few days and use some silicone to close the gaps. Mainly the volume key has an opening to the outside.
Good luck with the replacement!

I dropped my phone and the screen now doesnt respond properly: The hardware DID successfully upgrade to the XDA ROM. But touching it causes the backlight to go on, - but most of the keys dont do what one would expect them to do: The phone turns on with a reminder from the calendar on the screen which wont DISMISS or CLOSE. Pressing on the windows logo and then on the phone key causes the calendar to come up and I am not sure which numbers are entered when I do manage to get the phone to come onto the screen (none of the right hand numbers seem to work at all). Does anyone recognise these symptoms and/or could they just show that my SX-56 needs the ROM RE-flashing? I should add that pressing the Master Reset button with this ROM in place seems to make the phone shut off and then when you restart it, all of the data remains in place. I wonder if there is any possibility that the XDA ROM has prevented the reset button from working normally?
A user on another forum said that to him, '"Sounds like the digitiser is up the swanee - have you tried recalibrating it?"
10-12 vertical black lines started appearing to the right hand edge of the screen. Sometimes they are there, sometimes not. THere is usually at last one there somewhere. At about that time the screen stopped responding as I mention. Today the left third started displaying the same veritcal lines, though spaced quite far apart (about a millimetre). Screen doesn't APPEAR cracked: Does this sound like a digitiser and if so, how do you recalibrate it please or is there a link to somewhere on the XDA site which I cant find which might tell me? Or could it be the cable is loose in the circuit board? As you touch the lower right hand corner of the metal casing where the vertical lines are, those lines flash (the right 10 or 12) on and off. And every coloured bar everywhere on the screen or word of text has vertical lines on it (the white parts don't)??
Someone on ebay has said that his phone "fell from my pocket and onto the carpet and the screen cracked, I then used it for about a week" "I sold the screen to someone cause the wanted the touch pad part of the screen for there phone". and wonder what it was he sold or which part can be replaced on it? IS there a touch part and a screen part on this phone?
To be honest, itsounds like you have brocken a connection somewhere between the LCD and the gfx output, probably not possible to repair yourself.
I wonder where the break would be?
I thought that might be the case: I wonder if it would be worthwhile trying to get another screen?
I should probably try to take the unit apart and see if some break somewhere can be identified if it is a break as opposed to some electonic part having failed. It SEEMS to be in the lower right hand corner?
hello i have a problem with the touch screen...sometimes the touch didn't function corretly and seems to be disalligned.i've alredy tried to fix the problem with a hw reset and with the allignment option but nothing happend.anyone know how to fix the problem?
sorry for my bad english....
Try using the touchscreen again while pinching/squeezing the back and front of the phone together on the left hand side of the phone. Does it work as normal doing this?
yes it's work but i must doing a very high pression and when i relese the touch screen didn't function.
Same happened to my Prophet, all of a sudden the touchscreen failed.
IF ITS STILL UNDER WARRANTY SEND IT BACK FOR REPAIRS OR REPLACEMENT. Otherwise try cut an old credit card in half and place one half between the battery and back cover of the phone. This will preform the same function as if you were squeezing the phone like you did before (except hands free).
Dust
Look for small pieces of dust between the digitizer and the chassis, this can disalign the screen too.
Hello,
for first I've already read some topic covering the white screen problem. I have the white screen every time on my Hermes since booted. Going into bootloader also shows white screen. I don't see any signs of misalignment.
I've already taken apart my Hermes and reconnected all connectors I've seen, including D-Pad connector, tightening and loosening the screws by it. I see there's nothing else I can fix without replacing any parts (or am I wrong?) 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? (well I think that some chip is connected to flex so I don't know if it can be replaced anyway). My main question is: if the screen is all white, is it possible that the actual screen be faulty?
It could be a number of things which could amount to $$$$ by throwing parts at the phone - may be cheaper to just buy another. Before the completely all white screen did you have occasional white screens with increasing frequency? First try some of the fixes for correcting whitescreens - pressure on the dpad - etc. If you still get nothing the chip could have come loose - but who knows?!!!! Need some more information - history etc.
Unfortunately don't know the history... bought cheap off ebay hoping it can be easily fixed already ordered the screen, if no luck, will send as spares/repair in my country - should earn something anyway.
i have a fault with mine some times (well a lot now) when i open it or close it all the way i get a funny fuzzing on the screen and some times it just ends up going black, move it back and forth a bit and the screen collour is inverted. i have to press the power button twice once for off then back on and it stays normal collours till u move the screen again. is this called white screen?
Not really - yours should be an easy fix. Seems like the flex cable is either loose or cracked slightly. It only occurs when you slide the keyboard out right? Any problems with the front keypad - with the unit closed?
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 all ,So the story goes is I had my cracked screen replaced by my insurance 2 months ago. My new screen was fine up until a few week ago when this started happening..
youtu.be/lXv5xBA-r9E[/url]
Basically when I press hard on the top right of the screen I get ghost touches all over the screen. It also happens all the time when I use a case because of the pressure on the top right part of my screen.
I noticed that I can get my fingernail in between the 2 parts of the phone on the side. I really don't want to go a month without my phone again so I'm reluctant to send it off to insurance. Has anyone had this problem? Should I try a phone repair shop? Does this happen if a screen isn't fitted properly or is it another problem? Thanks
Seems like a faulty digitizer
More info... The screen works fine when I press it normally. It only goes crazy and when I press slightly harder or if there is a case on
