Reason for screen calibration issue - GT540 Optimus General

Hello everyone,
even tought I have a new phone I'm still in touch with the GT540, because now my brother is using it.
Nearly every ROM, beside the ones based on official 2.1 have problems with the accuracy of the touchscreen. Just like here:
So in the description of the video is written, that a new digitizer can fix this problem. Have anyone else tried this? I just ordered a new one on ebay today, also because the screen of the phone has some scratches.
It will take some time, till the new screen and digitizer from China will arrieve. But I will share my result with you.

screen defected, is this a hardware or software problem ?

ok, i bought a used htc legend and didnt have enough time to test it, so
before rooting the screen top part was not responding right(although the previous owner insisted that it worked fine and this is a root problem) but i thought because i'm not used to it. the day after that i rooted it and used the device for some time , which when i started to notice the real problem in the screen.
attached are 2 pictures demonstrating my problem
this is supposed to be a straight line, but at a certain point in the screen the line get broken as u can see.
so what should i do? (and returning it to its owner is nearly impossible)
(sorry if my english is bad)
Visit the previous owner with a baseball bat? I can't imagine this is a software problem.
Sent from my Legend using XDA App
if so, is this a problem in the glass touch screen or what? is there like an lcd underneath it that can be defected?

I bought my Leo December 31st, 2009.
I dont have touch screen problem until now
so r u the only one ???
No problem here, since Jan '10, was a little too sensitive on 1.42 rom, but no problem since.
When you are reading about how everyone has the problem, don't forget only people with the problem post, no one starts a new thread about how few issues they have.
Works Fine... Bought Late 2010.. Second Version (Yellow Reset)
i have mine since late 2009 (Leo eu) and used it extremely, flashed several wm roms, several android builds and once wp7. I NEVER had a touch screen issue, neither a hard button issues.
the only thing is that I just ordered a mugen battery, mine become to be a bit short.
I am sure 95% of us here are happy with the quality of this product.
but we always here in forums people that have problems, not those who dont need anything.
After 15 days my HTC HD2 repaired, just do not know what is left of the old phone when I look at what is replaced. Like it was smashed by a truck!

Defect was corrected by replacing the touch panel, casing, keyboard Fleta (54H20178-00M) and new SW's.
Had mine since November 2009 and had 0 hardware problems with it. Bear in mind that:
There is a thread exactly the same of this that has been and gone. It even had a poll on it
People don't start threads to say their phone is working correctly, so most threads are about problems. It does not mean that everyone is having problems.
Got mine back from lending it to a cousin, still working fine from when I bought it in April.
My HD2 works fine even though it was a second hand one with a smashed glass...
Had mine since last year, no problems.

I too have the revision version with yellow reset (earlier version has red)
Went out of my way to make sure it was revision version.
So far excellent, screen & buttons are perfect to date. Most people I know who ended up with screen issue had early version but most had also dropped there HD2 on more than one occasion.
Problem with these compact & cutting edge devices is they like a gentle life, drop them a few times (maybe just once!) & handle them roughly will limit lifespan greatly.
Heat in these devices can get quite hight too, I charge mine screen side down so heat can dissipate through heat-sink battery door rather than soak into motherboard & screen. I do the same when using it as a wifi GPRS internet modem for my notebook & also make sure it is in a cool spot (have done this since had a kaiser & used it for 5>6hr wifi modem sessions), Data/WiFi connection & charging simultaneously in the 34°C heat of BKK tests a devices cooling near its limits.
i have one with the yellow reset button and last night the touch screen stop working suddenly after installing google I/O android app.. man, i just cant express my feeling when i tried to unlock it and nothing happened
I really fail to see why we need a thread where people are expected to post;
"My device is working just fine...."
I really dont think this touchscreen problem is that widespread considering the amount of people who own HD2's compared to a handful of posts about it on XDA.
Im even less convinced that the colour of one tiny plastic component bears any relation to whether or not your touch screen is going to fail.
anyway.........

yellow reset has revised motherboard & different screen supplier.
HD2 model had a high level of returns, not to the point of a recall but enough for some networks to have a serious moan to HTC.
I have 7 workers on HD2's, 2 have had service repairs due to unresponsive screen so the problem is real.

Ok, that would make a certain amount of sense, thanks for bringing that up as I'd never noticed that being mentioned on the forums before.
That said, I still dont see the need for a "still working" thread. There are numerous threads for those with the screen issue to post in.
Thanks again for the info though
Edit;
While Im here, I might as well add;
Had mine since launch, T8585, has been no issues whatsoever.

Kind of agree but to see how many users have had a 2 year trouble free life span is interesting.
Think the revision details can be seen in wiki or HD2 tips thread.

Xoom no backlight?!?!

Hi all out there,
My xoom has no backlight? in some angle I'm able to see what's on my home screen, but it's all dark, totally unable to work around...
Someone know something about that? You guys around here are my only help. I have no warranty, cause I bought it from US and I'm i Europe....
Greets,
Philip
Interesting, this person here have the same issue http://forum.xda-developers.com/showthread.php?t=1767082
Hmm I still don't think it's a software sided issue but a hardware issue. You could open your XOOM and if there is anything wrong with the connectors, but you will properly have to replace the whole LCD screen. I had a few LCD TV fail on me before and it's generally the back-light that goes first, so it's not that surprising. Hmm another problem is I looked on ebay over here and a new LCD screen or touch digitizer actually costs more than what it's worth.

Dead Screen Touch

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

can't live without my phone lmao so I havn't done anything yet :/ probably just going to wait till the contract is over with verizon :/
Yesterday I noticed the same problem with mine (D801)...
I think I read somewhere it's pretty common hardware defect.
I'm out of warranty so I'll have to live with it.

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.

Xperia Z1 LCD+Digitizer replace

Hello xda community, my old xperia z1, had touch problems. Last summer i sunk it in a pool to take photos etc, and a day after that large parts of the screen were not working along with the rotation of the screen. So i thought i'd replace LCD+digitizer with a genuine one that i bought from ebay. I followed a great tut from youtube and with the correct tools and adhesive i did it. Only to turn it on and see that touch screen was not working at all. I thought out was discovered so i sent it back and got a replacement. I this time used anti static wrist wrap. And i just found out it didn't work this time either. After so many completely disappointing tries i thought that the problem might be with the ribbon cable connecting the mainboard with the screen so i quickly ( and without much thinking bought one for 12 euros).
I don't know what else to do and i can't even seem to find the real problem so my last shot is you guys. Does anyone know what the problem might be?
I would definately love to hear your ideas and solutions or even better if you got the same experiences I'd love to hear it. Please point me in the right direction, i would lovely appreciate it. :highfive: :fingers-crossed:
Thank you in advance,
deejaytelis
