If my screen is not responding to my touch, then which hardware component is at fault? I've switched between three ROMs already so I don't think it's a software problem.
Thank you.

That would be the digitizer.
Thanks, would you happen to know if it's easily replaceable or anything?

see if this helps.
Thank you again, but I just had another question come to mind. Is this a fairly common problem or am I just unlucky? Would you also happen to know why or how a digitizer would stop working? I've only had this phone for about a year

If you've had it less than a year I would call HTC for a warranty claim if you did not drop it or dip it in water.
This is not a very common problem but it IS a problem with any touch screen device with some small percentage where this fails. They mass produce these things and every once in a while it just dies.
Sounds like you're unlucky.
If you drop it/hit it a lot I know it can mess it up but that should be the only thing besides faulty hardware.
I think you have rubbed the touch screen tail under the red button. This is a very common problem HD2

So is there a way to fix this without buying a new digitizer?
I just explained what the likely problem. Since many people have had this problem on HD2. You can certainly try soldered cable, but this jeweler's work. If we disassemble the phone, then it is better to replace the touchscreen. Even better to replace the display assembly with a touchscreen, it will be easier.

Is there any news about the known problem about screen alignment or calibration?
Some people claims that is a software related problem. Some other people report it as a hardware problem. Any confirmation ony any side?
Any comment from the HTC support service?
Has anybody got it repaired with succes? Not?
Any information is wellcome.
I think it's been well documented by now as a hardware problem. I've traded two on warrantee and finally got one that didn't have the problem
I agree it is hardware issue simply because my Wizard is not having any alignment issues and i have owned it for a month. If it were software i should have experienced the same alignment issues that plague a lot of others.
I only have the issue when I get dirt, lint or other pocket goodies under the edge of my screen.

Which I would be inclined to say is the trouble. I have had this for the same reason.
I would say the wizard is re-aquiring the edges of the screen when there is some sort of crap pressing on it, and thus, skewing the screen off centre.
LOL, Thats my opinion and I'm sticking by it, LOL
Hi to all!
here in Portugal, some qtek 9600 (HTC TyTn) have trouble whith Screen Calibration and, HTC are reparing them.... so, if you talk whith QTEK, HTC, and all other seller, they sould fix this problem.
Sometimes a software cause after all???

UPDATE: REMOVED, WRONG DEVICE
Since about 2 months, my HTC HD2 sometimes runs into a strange behavior.
It's like some invisible fingers are touching the screen very quickly, triggering apps, menus, and sometimes calling people!
The only way to stop that is to restart the phone (but when the HD2 starts to behave that way, it's difficult to restart it, as these "invisible fingers" are still competing with MY fingers!).
I don't know what caused the problem in the first place, and I don't know what triggers the problem when it happens.
Is my HD2 out of order?
Thanks

It could be that your touchscreen is too sensitive and your sweat from your fingers is triggering it; Did you try cleaning the screen, your hands and using a screen protector?
your digitizer is going to die very soon
By "digitizer", you mean the touch glass?
Did it happened to you before?
Why so many of your phones had their glasses cracked?
Thanks

It's very probable to happen...
Try to massage the screen around the corners especially above the buttons.
There is some kind of "glue" to prevent contact with metal but if its old or used it could make this problem.
Maby you can trigger it or at least find the point where to press to make it stop.
=> using a heating fan (warm not hot!) to vaporize water could help too maby. No warranty here!
dertester123 you may have found the real cause of the problem, but I'll have to test more before I can confirm.
Cheers.

i have been having the same problem lately and i must say, i'm pretty sure it's about the sweaty fingers! i have read on other sites that the capacitive (?) screen is too sensitive and that many are experiencing these problems, especially during summer!

Just place some waterdrops on the display or use it with fingers that you put some lotion on....
Problem is when it gets under the display, but thats rather uncommon i hope;D
I case its just just sweaty fingers, what are pants for?

are you running android ics? In ics they changed the input slightly i heard, and maby its not ported correctly...
When using another music app or switching to generally other apps while music plays everything is okay?
I dont think its a virus or something, most of them want to spy or change userdata and not annoy you
I thought I had found the cause of my problem, but I can't confirm it, as this problem hasn't appeared since the middle of May, when I followed dertester12's advice to massage the screen on the corners!
But I noticed a spot in the middle of my touch screen where the "glass" seems to "touch" or to be glued to something underneath it. This spot is till here today, but despite of that, the problem is not occuring now. I'll try to attach photos of that.
So to sum it up, I'm still not sure about what caused the problem...

Well the touchscreen must be isolated from the display. Therefore they put some blue glue at the area over the buttons where the HTC logo is. For me I used alcohol to clean the touchscreen as I replaced it and had the problem that when pressure was added the layer of glue was to thin to isolate and gave me fake inputs.
You can test by massaging this area.
Also the contacts on the backside of the screen must be isolated to the housing and the screen. I could think that when you soldered the stock isolation thinned out too..
Last but not least touchscreen, display and housing must be grounded correctly. Therefore all parts are wrapped in metallic foil at the edges... To connect them..
As the touch screen is very sensitive to even little currents its often hard to find the problem as it could also be a totally different cause.
All the above mentioned points should be checked and are relatively easy to fix. But it needs total disassembly what - especially to old devices- has a risk.
Risks are:
That damn flex cables are old and tend to break. The buttons have small tapes on top that come off easily and never go back again... And many more things that break when dis- and reassembled to often.
Sometimes it's cheaper to sell defect HD2 and buy new/used one..
On eBay you often get very good prices for defective HD2..

Greetings,
I tried to search for this problem on this forum but I couldn't find anything specific to this device.
The tablet works fine in all aspects, except the screen flickers when the aluminum back is stressed, i.e. when its being held. The tablet screen will flicker in brightness as the back is pressed.
Usually the most reliable way to reproduce the problem is to flex the tablet, as if you were trying to split a piece of plastic into two by gradually flexing it until it breaks.
Therefore, I have concluded it is a hardware problem, but I don't know exactly what.
I apologize if I'm difficult to understand, and if you need any clarification, let me know.
Thank you everyone for your time.

Hey Kevin,
Yeah, seems like a hardware issue. But I advise not to "flex" the back too much
Probably could be 2 things.
1. Loose connector for the digitizer
2. Bad digitizer
3. Something grounding out against the case.
So my guess would be to spit the case apart. You can find videos on Google Search showing the procedure at You Tube. Then a good inspection of components, paying attention to connectors and the boards (for cracking).
I saw the other day that there are plenty of parts available for the 500, like digitizers, display glass and several other items. Check E-bay.

Thanks for your advice Moscow Desire. I've taken the back off before but noticed nothing unusual. Should I just take every component that can be separated out and inspect it? Sounds like a recipe for disaster for an inexperienced person like me.

Hi Moscow Desire,
I have taken my tablet apart with the instruction from the videos but I didn't see anything that is loosen so far. Do you think I will need to unscrew everything until I take out the screen to know what's wrong? My screen keeps flickering with white lines at the edge of the screen and it's really annoying. :crying:
Thanks!
for the past week my screen has been going whacked out on me.
the on-screen buttons would start clicking on their own, and sometimes the screen becomes unresponsive,
BUT
when i turn it off, and back on, it would work perfectly fine .
so i basically get a 50/50 chance if the screen going crazy on me...
now if it was the Digitizer, wouldnt the problem be ALL THE TIME?
as opposed to being random, could it be a BUG ?
Can anyone please help or advice, thanks !
If a factory reset doesn't fix it it is probably hardware. I have seen intermittent problems with digitizers before.

Have you called them? I don't understand why they would not honor the warranty.

Read the book that came in the box. Manufacturers defects pretty much always have a 1 year warranty.
Oh and LG.

I have a similar-sounding issue (on-screen buttons flashing wildly, et al.); I am thinking of opening the device to check on connection
Is it more or less likely, in your experience, that the connection between the display assembly and the board is loose from impact or whatever, or that the digitizer itself is just defective?
Thanks for your help.
I had the exact same problem on my device and it can be due to two reasons.
1. If your phone get extremely hot during use then the screen starts behaving abnormally.
2. If you had dropped your phone then there is a slight chance that you have damaged the digitizer.
I had the second problem and I have replaced the screen and it is working normally again.
My LG G2 (d802) started having dead screen touch in some small portion of the screen. I just installed Cloudy G3 Rom about a week ago and the problem started showing 4 days after installing the rom. Not sure if there is any connection.
Today i flashed Paranoid Android and i still see the dead touch screen problem is there.
Is it hardware issue? Or still is there any way to find out if its a software issue?
Any help appreciated

Exactly what part needs to be replaced? The display or just the touch sensor?
My one started going crazy. Now it detects press automatically as soon as I turn on the screen. Had to turn off knock-on feature or it would keep turning off and then back on the display again and again.

I was ignoring all the posts about this issue when I browsed the forums, I thought I was safe since my G2 is more than 6 months old and also because some people mentioned it was related to some type of screen (there are two models) and I was on the "safe model", which apparently is not the case. So today I started to investigate the issue and some people end up replacing the whole screen (digitizer and LCD) which I think I'll do too.
Replacing just the touchscreen seems like the cheapest option since the part costs less than $20 bucks, but I honestly don't recommend taking that path since it's really hard to separate the LCD screen from the touchscreen.
So yeah, the whole screen assembly runs for like $70 plus bucks.
Better waste 50 bucks more then when you need to use the liquid and special devices to stick the digitizer to the lcd, it isn't for people who have never done it before. Its especially harder on newer smartphones then from 2010. Thats also the reason why the nexus 5 digitizer isnt sold seperately since replacing it would be much easier and you wouldnt risk your display when replacing the digitizer.
For that 70 bucks you maybe also have the tools included to open the phone and there are many videos which you should follow carefully to replace it well. I would rather pay 70 bucks then going to some repair shop or service center which replaces it for 130 bucks and above. @in_core If you have warranty use it since dead touch isnt your fault and as I read its common so LG have maybe screwed up it somewhere or the rom caused it :/ but i don't really think the g3 rom caused it since people even get that problem who are fully on stock without root.
