Hi,
I wonder if someone knows the codes to check desire z's LCD! And should I just click back button after checking the screen to come out of the lcd check status?

confused in what you are asking... can you give more detail?

If you mean testing your lcd for errors then you dont need a code just get this app from market>super manager> it has a tool that run various test on you g2 and you can run it over and over again
dont really know what code you want.
Hit thanks if i helped
Sorry for creating unnecessary confusion
What I meant is that there are some codes that can be used to test various functions in our Desire Z. For instance, the simplest one is to check the IMEI number we dial "*#06#". I remember guys at repair center using some code like *#....to check whether the LCD is functioning normally. After dialing this code, we could test the LCD by drawing random lines using our fingers and if some part of the LCD is not working, it would not respond to the touch.
Now why I need to check the LCD: around one and half months ago, I was caught in heavy rains and though I immediately ran for cover, I doubt some moisture seeped inside my Desire Z. Since then the phone is working weird: not responding to touches, start dialing things on its own , vibrating without any touch from my side etc. Also there is a horizontal strip across the screen that doesn't respond to touch even when rest of it is functioning normally. I rooted my device after that believing it to be a software glitch but the problem is there. Some other people are also facing similar things and they suggested replacing the Digitizer. I just want to make sure is it only Digitizer that I need to replace or the whole LCD+Digitizer setup! I hope now I make sense.
And thanks a lot for responding quickly
I don't know of a diagnostics code for the LCD, but yes there are. Some for other functions, maybe try Google
There are apps out there that can do this as well as some Roms. I believe just about every ICS and jellybean ROM I've used has this in the developers settings
Its worth a shot but I don't believe this would tell you if its hardware or software, don't see how it could unless you can separate the ROM form the diagnostics (like in recovery)
My guess is its hardware, and visual problems are LCD, touch problems are the digitizer, well also the flex or motherboard could be the cause but almost for surely you are looking at replacing the digitizer, not too bad of a task, maybe an hour if you unfimilar and around 20$ on eBay
Good luck!

Thanks demkantor,
I just forgot about the developer options of the ICS roms. Just checked using it, everything seems to be fine with the LCD. Yes, I should go with replacing the digitizer. only I'm bit reluctant (as I was before rooting) since it involves almost dismantling the whole device...flex cable, lcd and then reach the digitizer. But that is the last resort . shall do it one day when the things get over my head. thanks for your help and yes, the thanks button pressed

Ho guys I recently got this phone and was working fine till today. Its not new but used. The Phone actually was working until I flashed a ROM and since then the left side of the keyboard does not work. I rebooted and went to stock sprint evo rom and still cant even start phonen with email cause the whole left side of screen letters dont work and the home button aint working like it did either. I was trying a 3.5 rom and even restored to multiple roms saved prior to all this but no luck. i think the roms was called Energy Runnymede and FEAR ME. any suggestions how to get this back. Tried multiple keyboards cant even calibrate it aint reading that side. Bummed out any suggestions guys thanks..
Sounds like a hardware problem to me

If the entire left side of the screen is not working then it's definitely a hardware issue. Good news is that you can fix it yourself for a fairly low price. I've never done it so I don't know much about it, but I've seen plenty of threads about replacing the screen/digitizer. Do some searching around, it shouldn't be too hard to fix.

Im going to have to agree with him it sounds like a hardware problem. And as far as fixing it yourself it is fairly easy. My suggestion though is open the phone first because HTC had this brilliant idea to make a phone that used two different flex cables. So with that being said open it and see if your phone has the small one or the big one, you dont want to order the screen and then try and fix it and the cable be the wrong size. (if you choose this path your looking for the Evo LCD and Digitizer Assembly or Evo TSP/LCD Assembly, both the same part just named differently based on where you get it from just CHECK THE FLEX CABLE size and save yourself some trouble) Or the much simplier and cheaper fix take it to s Sprint Repair center and let them look at it. As long as its not physically damaged or liquid damaged you'll be fine and they will look at it and either repair it or replace it as long as you have TEP if not should just be a $35 fee again as long as its not physical or liquid damage.
Hi All
For the last couple of months my desire has had an intermittent problem with the touch screen. All of a sudden it decides you're trying to pull down the "notifications" screen when you're just touching the touch screen, sometimes it also decides you're trying to hold and drag when you're just tapping the screen, sometimes it simply stops responding. These problems are usually solved by tapping the top button and putting the phone on standby then tapping it again and waking it up - although sometimes it then won't let you drag down the screen unlock until you repeat the on/off standby procedure a couple of times. The problem varies on connecting my phone to my computer.
Given that in between these instances the touch screen works as normal I'm guessing it shouldn't be a hardware issue, but the intervals between these problems appear to be getting shorter (either that or I'm just getting more annoyed by it recently). I've had a quick search of the forums and haven't immediately found anyone having this precise problem. Is it likely a question of trying factory reset and if that fails sending it for repair?
Thanks in advance
Similar issues. Don't think this is hardware.

I'm having same problem, mine started couple weeks after I installed cm7.2, I tried another rom, no luck
Its definitely not software. I've tried froyo, gb stock with s-on and no root. I've been on ics roms cm7 roms but this problem occurs on all. I'm giving mine for service today.
Sent from my HTC Vision using xda premium
Well since the OP didn't respond here's my suggestions. If you think it's software then just flash to a stock rom. You should find a number of them lying around the forums, and instructions on how to flash. This will mean your phone is unrooted and will need to be rooted, as well as taking care of installing a recovery and etc. This should correct anything wrong with the software.
Otherwise you busted the digitizer, which is actually very cheap to buy on Ebay. You will have to take the phone apart which can be time consuming.

Hello,
Any luck with the Tocuh Input, is your phone back from service? I am also facing the same issue....
I had this problem on my G2 a while back. It was a hardware problem so I ordered a new touchscreen and replaced it myself.

Hello Whiskey_Tango / Others,
Can you please let me know the details of the touchscreen component that you ordered for your G2? My HTC desire Z touch screen has also gone bad (unresponsive at multiple points) and I feel that changing the hardwre should do the trick.
If possible, let me know the touchscreen specs (model / part number) as well as any online website from where I can order it !
Many Thanks !!
From eBay search for HTC g2 digitizer
Be careful to get the one for the vision not for the magic
should be about $20

Thanks for the quick response. Before coming here, I had a mobile service shop take a look at my handset and he had mentioned that for HTC desire z, the "touch screen" comes with the "display" attached to it. Did he meant the digitizer only or (digitzer + LCD screen) or he was simply trying to rip me off ?
I am very sure that there is nothing wrong with the display on my handset, its only the touch functionality that is not working properly.
Which one of the following do I need to search on EBay?
gultek.eu/htc-spare-parts/digitizer-touchpad/desire-z.html
or gultek.eu/genuine-parts/lcd-modules/htc/desire-z-hd3.html
or both?
Thanks again in advance !!
You need just the digitizer, if you're doing it yourself it takes about an hour if you've never done it before, don't buy the lcd if you don't see a flaw in it.
Some people sell the whole front chasis with lcd, digitizer, front bezel all connected for ease of replacement. May be easier but you will only shave of 30min tops and spend 3x as much

yeah this happens to my G2 a lot. I got my phone fixed a while back (2-3 months ago) becuase the colors on my screen were screwed up and the ear piece was broken. i took it in and he replaced a couple of cables. it worked fine but now sometimes the screen is just having a straight up seizure. it flips through pages so fast and it goes from page 1-2 and back and forth and then the virtual keyboard presses multiple keys and just its crazy. i feel like the guy that fixed my phone didnt plug in a cable all the way. but yeah thats my problem. i dropped my phone the other day and ever since my phone hasn't gone into a seizure lol
Hi, did you solve your problem? I have the same with my desire Z. It click alone in several place on my screen.
And I ask me if the problem don't come from the lcd digitizer control instead of the touch screen digitizer

Yes replacing the digitizer did fix my problem. And a year later the replaced digitizer started giving problems. So I ordered 2 extra digitizers off ebay. Both of them turned out to be duds. Surprisingly the second digitizer(which I replaced a year ago) fixed itself.
I think Im having the same problem,
bottom part of screen (including the home, menu, back, search buttons) aren't functioning half the time,
is there any service manual, or link to information as to what I need to tear apart on my DZ?
should this be enough? EBAYLINK
what do I need to replace the digitizer?
Today is a very sad day for me somehow my new htc one x's capaticive buttons stopped working i restarted and even factory resetted and they are not working anymore
my previous htc hd2 was stopped digitizer working too. How unlucky i am.
I guess I neet to install CWM and using on screen button
which rom do you reccomend? ı used to install couple roms to hd2 but i havent tried with one x
thank you all
Factory reset will only reset it to the rom you have flashed. Have you tried flashing the correct ruu for your phone? When you say it's new, how new? New enough to return to where you got it for replacement?

capacitive buttons stopped working
my htc one x touch sensitive buttons have stopped working like a week ago, i then installed the coldjellybean by which i got that onscreen buttons after 2 days the buttons started working n i thought of selling the set but as i was going to make a deal with a person that day the problem appeared again, i dont have the warranty left and the screen replacement is quite not an option. Is there any trick that i can work on to make them work again.

i took the phone to my local market n came to know that the their isnt any separate capacitive buttons cable, it is embedded within the lcd, so if i have to order then whole complete lcd + digizer + module, and i checked the online purchase price is almost the same price the local market ppl are offering that is near 60 dollars.
Just that i am not sure why does the buttons stopped working and if somehow why they started working n now have again stopped ;(

not sure what you mean.. look at this: http://www.ebay.com/itm/New-Touch-S...865?pt=LH_DefaultDomain_0&hash=item4d02ec98e9
anyway it happened to me with another phone that a portion of the digitizer stopped working for a few days, then it started working again and then it stopped for good and had to replace it.

it is hard to separate the digitizer from the lcd but it's doable and nothing like the iphone digi+lcd that uses an epoxy adhesive. so if you are carefull (or have someone skilled doing it for you) you wont break the lcd and you'll save quite some money. it's true though that the new digitizer wont stick to the lcd as well as a "genuine combo digi+lcd" and you will notice dust building in between the two. my advice, if you know someone that is skilled enough, try get the digitizer off without breaking the lcd and if you manage that then buy the new digitizer. otherwise since you said that changing the whole digi+lcd is not an option you can always try sell your one x as damaged or use it as an expensive paperweight.
best of luck mate, i hope you solve it one way or another.

haha that paperweight thing made my day... well thanks for the advice but i think i am going to wait until it gets ok by itself as it happened before until then icecoldjelly rom would be a temporary solution for the onscreen buttons. Thanks anyway
Okay, I haven't actually used this phone in ages, over a year, but a friend of mine is long-suffering with a BlackBerry and I feel obliged to end her suffering. There are two problems:
1) She wants Sense 4.0.
2) The digitiser is smashed and non-responsive. (A replacement has been ordered)
Now, I am sure that there is a few Sense 4.0 ROMs lying around here due to the fact that HTC released the Desire C, which has the same resolution screen.
So, I started to go through the process of unlocking bootloader, flashing recovery etc and fell at the first hurdle. When I had this, I didn't even look at the developer options, which seems to have screwed me over, because USB bugging is disabled.
So, basically, does anybody know how to enable USB debugging without actually using the screen? Or anything that could enable me to get all of this done now, so I can just replace the screen when I get it and give her the phone?
Nope. Gotta have the screen! And there's not a single sense 4 rom and there never will be. Desire C is armv7 the WFS is only armv6; it's not a case of screen size, but processor compatibility

Ouch.
Indeed, you're going to have to fix the screen first.
I faced a similar problem some time ago. Unfortunately, the digitizer has to be fixed first
Alrighty then. I've seen many reviews saying the far right side of the screen often does not respond on replacement, is this true? I was looking at one on Amazon, although the seller is "HTC" I don't buy that for a second.

I'm very curious on how you proceed on this. I got the same phone and exchanged a non-responsive (shattered) digitizer to a new one which also seems like it is totally unresponsive.
I have read that you need to go into diag mode and calibrate the phone after exchanging digitizer, which seems impossible without USB debugging is set to ON. Unfortunately mine is set to OFF and I'm stuck with an unresponsive digitizer...
Did you get it to work?
Hello everyone.
I recently bought a sgs3 t999l t mobile version with lte capabilities and right away it has 2 noticeable problems. I do not hava a bill nor insurance, so I am going to try to fix it myself. When I first got the phone, the touch screen wouldn't work properly. When I turn the screen off and awake it the touchscreen works again every time. I asked a few repair shops and even samsung themselves but no one really knows the solution. One person said that the digitizer may be going bad. Another person said there may be a bad connection with the touchscreen.. Most of them told me to just replace either the glass or the digitizer and find out but I do not have money to waste. I believe that someone before me may have flashed custom roms and may have damaged it a little because when I first obtained the phone, software update was unavailable due to modifying the phone or something like that. When I checked again a few days later, I was able to update.
My second problem is that my screen cracked straight across the earpiece a couple of days after I bought it and one day before my lifeproof case arrived. I put it in the case and the crack multiplied by 7. My explanation is that the company I bought it from replaced the glass with a cheap non samsung version of the glass. Does anyone have any ideas about what to replace and how?

Samsung will still honor warranty sometimes based on your IMEI. They do have ways to track in Carrier's database. Just give it a try.
If you really have to do on your own, you are looking to replace Digitizer & / or LCD.
I talked to samsung and they told me a cracked screen voids the warranty..
Sent from my SGH-T999L using xda app-developers app
Then your recourse is to replace Digitizer and LCD. Others have tried replacing just the LCD but had limited success. Depends on your soldering skills I guess.
Watch the disassembly vids, for one thing, you dont want to attempt to do just one or the other, another is I dont think you can buy them separately.
Hint: if you do go this route, make sure you buy an assembly that comes already attached to the housing. This will save you a huge headache!

If its got its own motherboard, yes itll have its own imei. But itll only be blacklisted if it were stolen or reported lost. If you still have yours you can always swap them out. Its very easy to do.
