Display problem!! Please help!

display does not always work. The phone is not rooted. So I don't use set cpu or anything like that. The problem that I am having is when I turn the phone on (after it is shut down) it does not display the htc logo, then when it gets to the g2 it does not display that either. When the finishes turning on the screen is still black. I can press the digitizer where I know the unlock is and I can feel it vibrate then when I unlock it I can still feel it vibrate when it unlocks and it takes about 2 to get the screen on from this just pressing the on and off power button. Some1 please help. PLEASE HELP!!! Any Ideas?

I searched other forums and seems like I am not the only one with this problem. All they suggested was to take out the battery, mem card, sim and leave it for a while and then put everything back in, the display was working fine again. Unfortunately, it didn't work for me, not even restoring factory default, not to mention going through that painful "shooting in dark" process.
I am already aware that if all things fail, LCD has to be replaced. Other than that if anyone has any other suggestion(s), it'd be much appreciated. Otherwise thanks anyways

I am going through same problem. Haven't found a 'non-LCD replacement' solution yet. Maybe the above will make things work for you. There was one guy who said he turned on the phone without the mem card. So you can try this as well.
If you find anything else, please share.
Good luck.

I didn't think it was a dead lcd because after about 2 minutes of the phone already running the lcd will turn on again. and I saw your thread that said to take everything out I did try that and it did not help. any other ideas?

Does the screen flicker? If you open it up halfway and gently nudge the flex cable, does it do anything?

I juat tried and it does not flicker at all. Once the screen in on there are no problems, its getting the screen on that's hard. Its realy weird. And it started about a week ago and the phone is out of warenty.

It doesn't sound like it should be a problem but I want to root it. And install a custom rom, and I am scrared to do that because when I boot into recovery I cant see the screen.

How can it be out of warranty? G2 wasn't released until October 2010 and HTC provides a 1 year defect warranty. Here is the link. http://www.htc.com/www/support/warranty.html. I didn't look at anything outside the US though.
This is not a caused by physical damage so should be covered??
Also, Tmo, if that's who you're with might just send you a new one?
I'm assuming you don't have the Asurion 5.99 plan? That would cover it for $130 last resort.
Oh, also, Visa or Mastercard will sometimes take care of you if you used it to purchase the phone so check with them in a pinch.

[Q] simcard problem. need help!

i've had a desire (normal version) since the day it was released. but when the HD came out, i just had to have it.
in the beginning everything was just fine with my HD.
but since a little while, the simcard is acting weird.
yesterday afternoon i put the simcard in (had to use a different phone for a day), and everything worked fine. no problems at all.
this morning i woke up, and i looked at the screen of my HD.
no reception, and a little warning telling me to set the time and date.
(it has done this before, it started about a week after i got it).
i try calling, but the phone says "no simcard".
i remove the backcover, and there was my simcard. still in perfect position.
i even tried a little piece of paper to really squeeze the card in.
i took out the simcard, cleaned it (just in case), put it back in and turned off the phone.
a minute later, i turned on the phone again and everything was fine again.
but it's just a matter of time before the phone will say that there is no simcard.
it does this almost every other day, and it's really really annoying.
(it does this to with other simcards)
if i put my simcard in another phone, i don't have any problems, only the HD does this.
can somebody please help, because it's really annoying if i have to restart the phone every other day because it won't recognize the simcard anymore.

If a hard reset (back to factory defaults) doesn't fix this then I'm afraid it sounds like hardware fault and you'd need to get the phone replaced.

i can't get it replaced (i've been told).
a few weeks ago the phone fell and the screen broke. the screen has been replaced but i've been told that i don't have any warranty on it because of the repair.
the thing i don't understand is, why work perfectly for a whole day (sometimes even more) and without warning all of the sudden the simcard isn't recognized anymore.
with hardware faults the fault should be there all the time, not just after a certain amount of time.

Hardware fault can still be intermittent just like a mechanical fault.
How did the hard reset go?
Sent using witchcraft via XDA Developers Premium App.

i used this guide for the hard reset: http://www.hard-reset.com/htc-desire-hd-hard-reset.html
that was about a month or two ago.
the phone still acts as if there is no simcard sometimes.
the hard reset didn't do anything. (except for losing some data...).

Then if it does this with every SIM card you tried and the SIM cards all work fine in other phones (ruling out SIM card issue) I don't know what else it could be other than hardware.
Software issue can discounted as you have done a reset.
How long getting it back from screen replacement? If not long I'd blame that and insist they repair it.

i had to sent it twice actually.
the first time they had it for about 2 weeks because they had to wait for parts.
then i got it home, but the glue for the screen didn't stick well enough (1 corner got loose) so i called them and they fixed it for free.
this time they had the phone for about 2 weeks again.
but how the hell am i gonna explain why the simcard holder was affected by the replacement of the screen?

You don't.
The phone has to be pulled apart to change screens and anything could have happened.
If it was only a week ago you got phone back or less I'd just contact them and say "ever since I got phone back this has happened" and ***** till they agree.

made the call, the're gonna look into it.
so i'll have to sent my phone again, and wait for the're findings.
they first check if it has to do with previous repairs, if not it's not covered by the warranty.
*sigh...*
been sending it up and down for the last couple of months...

yeah... i found that one out the hard way.....

well, i just got my phone back. the statement they included says "no error found".
those goddamn f%$#^&% probably didn't even test it out.
it doesn't act up immediatly, it usually happens after a day or so.
maybe they couldn't find any hardware problems, but i know it's still acting up.
i'll just wait till tomorrow to see when the phone stops working.

Just call them back and point out it is intermittent and often takes 24-48 hours after inserting a SIM for it to fail again. Just keep at them.

yeah i will.... on monday.
if i call now, they'll say "send it to us, and we'll have a look".
they don't work in the weekend, so i might as well wait till monday and have a few days with me precious phone.
i haven't seen it in such a long time, i'm starting to miss it...my precious... ;-)
but on the serious side, i really wander what the problem could be. i just don't understand why it suddenly stops recognizing my simcard.
i'm not able to fix it, but i'm still curious.

Is there any hope open to all suggestions

Here's the problem around the second week of this month my boyfriend's Acer a100 bricked itself. When you turn it on it gets stuck on the Acer logo and will not go any further. I called Acer to try and see if they could help me but they stated that it was a hardware issue and to send it in to be repaired; however, there is some major damage done to the screen. It is crack very bad but it is still usable. I'm wondering is there anyone that can give me some advice on how to fix it or what to do to get it where it can be used again. Another thing is I'm thinking that because of the damage done to the device that it voids the warranty, does anyone know if I am right? oh yeah his device is not rooted.

My device had the same problem one day. i messed around with some things to try to fix it and just made things worse , when i talked to acer it seemed as if it was a common thing because in a matter of mintues i was getting the details of where to ship it to be repaired. To my understanding the cracked screen shouldnt be a problem since they would be replacing the motherboard(i believe) and the screen will come back the same way you sent it to them.

I think thats what he's gon have to do because I have clue what else he should do. I wanna call back and ask them will the damage effect the warranty but I'm to nervous they will actually say yes.

Send it to them and if they call you then you accuse them of breaking it...problem solved lol

Touch screeen doesn't work after rooting phone

Hi,
after I rooted my phone, I realize that touch screen doesnt work. Before this problem I get custom rom 2.3.3 and when I wanted to root it problem appeared. I've tested other roms but this doesn't repair touch screen. In tutorial of rooting Desire Z i had to put file DZ_PC10IMG and start bootloader. At half of the installation my phone turn off, and I dont know why. I tried second time and then no problems appeared. When i turned on my phone touch sreen was dead. I found solutions on forums only for xperia or samsung phones. Is it possible that rooting can broke hardware? Oh ,I also installed CWM Touch Recovery but there my touch screen doesn't work too. I don't have warranty so I want to try repair my fone in home.
Can u help me reapair that?
PS Sorry for my english.

The act of rooting in itself cannot damage your touch screen but i will say its odd for this to happen at the same time you rooted.
You can try a full return to stock if you want to rule out software/firmware problems but it is likely hardware
A new digitizer will be about 20$ and is the most likely issue, could also be main flex cable, about 25$ but less likely to what you describe
Either way the hardware fix takes 30-1hour if you quick but if youve never done this sort of thing expect a couple hours to be safe. It is rather easy and plenty of tutorials
Best of luck to you

i think something went happened with Your hardware..

HI, Today I've changed digitizer and it doesn't help at all. I think it's problem with software. Do you have any idea what can I do?

You can follow a guide to return to stock, all firmware/software that was changed in rooting process would be changed back, this will either confirm or rule out any software/firmware issues

Random (and ghostly) touches on screen

Hi guys!
I have a F180L (converted on a E975), my phone never fell from any distance, or had any kind of impact, BUT...Since I updated to last version o Carbom ROM, I've got a issue on my screen...
There are random touches on my down-left corner of the screen. It's completely random, while the charger is plugged, or not. But it only happens when an app is opened, while in homescreen (even on google now cards) everything is ok...
I've already flashed another rom, the AOKP Android L release 11, the problem still here...I installed a screen tester app, and this corner is not recognizing when I touch.
What can I do? Is there any kind of fix for it?
It's really annoying (mainly while typing)...
Thank you for any help!

I guess its time for a replacement.

Made some research on other forums and found some people with the same problem, but on other devices...On Nexus 4 and Xioami (mostly)...They solved this by replacing the battery...I'll try to do that this week...
But any other tip about can help...

it might be a kernel issue
if u have jolla kernel try changing the kernel first

I have also the ghost touching on my E975.
Tried to do a scan with antivirus with no luck.
For instance it's hard to dial number, because there are ghost touches often.
It's like on tihs video, but I have touches even more often:
http://www.youtube.com/watch?v=EHFtafL-HKc
I'm on stock KitKat 4.4.2 ROM.
Any ideas about the issue?

I also had this problem and I sent it to service center (Still in warranty period). They replaced my phone touch screen and the problem is solved.

Thanks.
It's relatively common issue, hope it will not appear again...

Sorry to resurrect this thread but I seem to have a problem with my screen, not with the ghostly touches but my screen has like one part of it not responsive to touches especially the keyboard. While typing in portrait mode I can't type in the letters x and d and the whole line of the screen above those letters can't respond to my touches. The others are OK though. Anyone else having the same problem or is it just me? Already flashed different ROMs but same problem

So...I didn't manage to get a new battery to perform a test yet...Maybe I'll do that until the end of this week, and post the results here...
About the kernel...Mine is "3.4.0 [email protected]" ...
Going to update to new Kevin's L ROM and see what will happen...Hope I can help u, guys...

I had the same problem as well, unfortunately my phone was just out of the warranty period so I couldn't get a repair or replacement. I tried everything to do with the software and firmware at first to see if that was the issue(no luck). I noticed when my phone was either hot from heavy usage or charging, it was at its worst..couldn't even put my lock pattern in without it spazzing out. After almost throwing my phone at a wall numerous times I decided to get a new digitizer (easily bought online at reasonable prices). Watched a tutorial on Youtube and replaced it successfully and haven't had a problem since.

That's exactly the SAME situation the occurred today, almost threw at a wall...when data is on heavy usage, it gets worse...I'll try this, but I seriously thinking about to get a new Moto G...'cause this digitizer gonna take a long time to arrive at my country
Thanks for ur information, dude!

So tried the touchscreen test and found out it was like a whole strip of screen that got affected. It was okay just a few days ago though,

Yeah no problem and thats unlucky. I've got the Korean variant and wasn't ready to wait weeks to get my new digitizer either from Asia. I managed to find a european version that arrived next day and included front housing aswell (although modifications were needed a bit for the internals to fit). Yeah the Moto G look great but it seems to be more of a downgrade from your current handset right?

I live in the UK I managed to find one here on ebay. I know you can get some from Italy , Spain and I'm positive there some in US aswell. Search "E975 housing or digitizer" depending on what your after. Do be careful as some replacements screens lack the LG logo or a bad quality. Im would give direct link but im not sure about the forum rules on that are. If your still unsure do PM me your country and I'll PM you back an appropriate link.
Hope I helped.
