Having problems, getting worse. - Nexus 4 Q&A, Help & Troubleshooting

Got my 8gb nexus 4 a while ago, no longer under warranty. At any random given time, my screen starts to flicker. If I look closely, I can see an "image from before" - example, let's say I google just a picture of a smiley face. The screen later starts flickering. On the lock screen, I can see all the regular lock screen stuff, then faintly in the background I can see the picture of the smiley face. Usually the entire screen is also discolored to a greenish tint, sometimes with lines running up and down vertically. 2, 3 reboots and nothing, then put up with it while using the phone, and all of a sudden it stops.
That's problem 1.
Problem 2 is that whenever the phone is plugged in and charging the touchscreen goes wonky. Nearly impossible to unlock the phone because when doing my unlock patter, let's say it's just a Z pattern, after doing the top line of the Z, and trying to go towards the middle, it jumps to the bottom right. Over and over, or it just gives me a red line as if I let go of touching the screen. Finally say "F this" and unplug the phone to use it, because it's hard to use the phone at all when the touchscreen is jacked like that.
Problem 3 has just started within the last few weeks to maybe a month. Any time I make a phone call, as SOON as I hit the "dial" button, or tap a contacts name, the screen goes black - usually, yes, this is because of the proximity sensor to make the screen off when near your face. But no, this happens if I were to place it on a desk and tap "dial", if I put it near my face then away again... Of course this makes it literally impossible to dial numbers, use speakerphone, or even HANG UP during a call. As if that wasn't bad enough, after the call ends, the phone still won't "turn on" for another minute. I have to wait till the other person hangs up and the call ends.
If I call someone and get to voicemail and don't want to leave a voicemail I have to just hold powerbutton till the phone shuts off.
This is sadly probably the worst phone I've ever used.
I have tried reflashing stock image, tried custom images, custom kernel, custom kernel with stock image (franco) and they never solve problem 1/2. Haven't tried it yet to solve problem 3 because I know it doesn't solve the first two problems anyway.

1. are you using android 4.3? if so.. jwr kernels on jwr roms or jss kernels on jss/jwl roms. or you get tbe graphics issue you described.
2. use a different charger. ive had the same thing happen on different devices. even though it was their charger, replacing the charger fixed it.

Just want to make sure, you mean that, if I'm running 4.3, using a JWR kernel/Rom or JSS kernel/rom will fix the problem, correct? And if so... Well.. What is/are said Roms? Not familiar with those two acronyms.

is there any solution to "screen can't switch on"?

at the begining , my HD is fine.
But , after 2month , the phone has some rotation problem( it doesn;t matter, as you can solve it by pressing the on/off buttom )
But now, the phone's screen can't switch on, when i touch the four buttom on the surface of phone, it still vibrate..just i can't switch on the screen"
i have already tried all the things like take out the battery, press the reset buttom... the problem still occur,
Screen can sometime turn on luckily~
but, if the phone's screen is switched off for a while, the problem still occur..
can any professional heal my phone?

Obvious questions: Have you tried a hard reset?, Diff rom? Have you loaded up anything weird that mighta casued issues? If it will do a hard reset then do it. Start from scratch. If it works then be mindful of what you reload it with. If that doesn't get it, try a diff rom. At this point you got nothing to lose. Will it go into bootloader mode?
Battery comes to mind also. Have you run it down to nothing? Sometimes that will affect the charging capabilities. When the screen is dark can you still hear sound? Def do the HR.
My suggestion would be, to give the HD to your reseller and get it fixed.
I have had the same problem, and as my HD also didn't connect to my PC anymore, I send it in, and got a brand new one, because they couldn't fix it. Make a backup while you can, because the problem will get worse over time.
Likashing, the same exact thing started to happen to me a couple days ago. I've hard reset and flashed a new ROM. It seems that the problem is intermittent. After I just let the phone sit for a few minutes, the screen will come back on. It makes me wonder if this is heat-related issue. Anyway, I'm screwed, because I have no warranty since I bought it from a guy in Australia (I'm in US and needed the T8285).
I'll definitely be keeping an eye here to see if there's any resolution other than repair.
while the screen does not turn on, have you maybe tried to use another phone to call your HD and check if the screen turns on when the call arrives?
maybe if the screen turns on it's more a software related issue (so hardreset et cetera might be worth a try), if not, i fear it's hardware

Good point crashDebug... I will definitely try that the next time the behavior is exhibited (right now is one of those times where I can't intentionally duplicate the issue... of course!)

...i have no warranty too....
in Taiwan , there are couple of people have these situation, the maintenance staff working Htc, said that it is a motherboard problem or the screen problem...but i wonder that why only few people have this problem. My phone is completely fine before i flash the HSPl1.56OLINEX.but when i try to flash back to Hspl 1.4 , the problem still happen.....

i have tried diff rom and diff HSPL....
sometimes, the phone's screen still can turn on luckily, then i can go to bootloader mode, but if the phone sit for a while, the phone's screen can't turn on...then i can't get into bootloader. ..
i can hear sound when someone phone me...but the screen still keep dark!
Exactly same problem here
HTC purchased in Sweden.
Cant switch screen on, when incoming calls come it rings but no screen alive. Vibration when pressing the buttons at bottom. And the low battery sound i can here when low on battery.
When connecting it to charger the orange light at power button will not light up (orange) as usually.
My problems started when i had the HTC in my jacket pocket, a VERY rainy day, so the phone was moist OBS not wet. Thats what i beleive ghappened to my phone.
And now i can not find the purchase receipt to the phone
It might be entirely unrelated, but the screen on my THD also had the same problems immediately after a few flights from coast to upcountry 1800m elevation during summer. The system powered up but the display remained off, and no amount of fiddling would switch it on.
The first time it took a few hours and then spontaneously corrected itself. The second time I had to remove the battery for two days, and then all was fine again. Only happened after flights from coast in summer. It hasn't happened again, but then it's winter here in the southern hemisphere.
I suspect condensation, but that's only a guess...
I have the same problem too here in Australia. It started with the screen not turning on but the buttons still work. Then you'll sometimes notice the screen is inverted and upside-down.
I've sent mine in for service. Haven't got it back yet but I understand the motherboard needs to be replaced.
In short, this is definitely a hardware problem and if you look around the discussions on the net, this is slowly becoming quite a common problem with HD.

Yes exactly, I have had the upside down screen too! Well at the very least it is good to know that people are experiencing this problem other than me. I love this phone so I will have to pay to for the repair. If anyone here has any idea or estimate of what this will cost, please share this here.
The problem for me was the moist, after three days it started to react again... And now it seems to be working...
I guess the air up in the mountains are moist... maybe...

So then that's two people so far (including AFW from the first page) who have said that after some situations involving moisture have passed, things are back in working order. I hope for the same to happen soon.
so it is due mainly to wateR?

I doubt it is related to water. My device never gets near water or moisture and still experience this problem. I do wonder if it is heat related as the device can get quite hot during charging and perhaps cause the motherboard to play up after a while.
btw, does any of you use some sort of plastic/silicone cover. I wonder whether this type of cover blocks the heat from dispersing.
As i understand it, so far only people who have flashed a different ROM (and with it maybe radios) to their device. If it's a heat issue it could be something to do with the radio version. I have tried different radios and there was one in particular that heated my phone up like crazy while i was listening to music without the screen on (but i don't recall which one it was).
I only used stock rom and never flash my device and still have problem...

I do not have any type of cover on mine.
I agree with the possibility of it being a heat issue though.
Very perplexing. This past weekend I again travelled from Joburg to the coast (from 1800m elevation to sea level), and again the THD screen stopped responding to input whilst at the coast. I desperately fiddled, reflashed, hard reset at least 10 times to see if I could get the screen to work, but it always booted up locked, and no amount of fiddling would do anything. I even put the thing on an oil heater for a few hours, hoping that if condensation was the culprit (my current theory) then a goodly dose of heat would at least evaporate any moisture, and once, for about a minute the screen responded, and then again went dead to touch. I had to use another phone all weekend. This evening, on returning to Joburg, I resolved to get another device, maybe the Diamond 2. After a few hours back home I retrieved the THD, put in the SIM and, lo and behold, it worked fine. This is most vexing, but I fear the THD will have to go -- I just can't live with this unreliability. Sad, really, because I love the big display, I love the fact that guys like Throy are cooking good ROMs. In many ways the THD is about the best out there, at least for my needs. But that &@&* thing has to be reliable.

Touch screen random inputs?

I did a DIY digitizer replacement a month or so ago, and its been working great up until a few days ago. Now, when I go to touch one of the soft buttons or type on the keyboard, the phone "flips out" and starts registering inputs in all random spots, sometimes getting stuck on that spot. I am totally stumped.
I double checked and all the ribbon cables are seated and such, and tried flashing over to Modaco rom from Cyanogen (thinking it might be software)... no luck. Can't even replicate it consistently, it seems to have a mind of its own.
Any thoughts as to what is going on?
Well I know that it has been an issue for some people and the general idea is that if you push the power button and put the screen to sleep and then wake it back up 20 seconds or so later it will work again. I have to say to also wipe your screen clean as well, build up on the screen can cause wonky behavior as well. Good luck.

this sounds exactly like the glitch that all nexus ones have, stock ROM. just lock then unlock the screen and it fixes itself.
the word is that it will be fixed with the 2.2 update. fingers crossed.
I thought it was that issue I read as well, but the power button glitch-fix everyone speaks of doesn't work.
I actually used my pry-tools to unseat the digitizer from the rest of the phone and kinda let it dangle, and 90% of the issues disappeared.
I am wondering if it might be the digitizer pressing up against the metal backing thats causing it to ground out and cause these issues, since the original phone was held in by a foam-type adhesive which I don't have on it now.
that's very possible. the power button resets my glitch 100% of the time. so sounds like something else is going on with yours.

I don't think its the famous touchscreen issue that we've heard because it was reported to register a click few centimeters below the touch point. Here in this case, the guy says that it randomly registers clicks at different spots.

I hope that reboot fixes this problem....
I've given up on the task for now, went back to my iPhone 2G till I can figure this out... its definitely not software though... and the digitizer still registers accurately when I don't have it seated into the phone...
No issues here on cyanogen 5. 0. 6 I love this Rom and have 0, yes I said it zero issues..... running solid for almost a month.... sorry ya have them issues I hope ya get em figured out...
As others says, just a quick lock & unlock fixes this. No need to wait 20 secs, I do it right away. Power, power, slide to unlock and I'm back in business.
For me I'd say it happens maybe a couple times a week? What about other people?
On stock it happened like once a week.... for me
none on custom so far after 3 weeks
yeah a couple times a week is it for me too. I wonder if view identified the issue and fixed it in the update. I'm sure some Google employees experience the bug.

Strange Touchscreen NAND Issues

ok, I have a strange issue that I can not seem to find the answer to. Whenever my phone locks after not being used etc. When I wake it up, the touchscreen will not let me unlock. It takes me close to 50 attempts to do so. However once I actually am successful in getting it unlocked. The touchscreen works flawlessly. I have tried several different builds, all of them I have the same issue. I have done Task29 and started fresh on that front each time. I tried a couple different radios. Any suggestions?
**** man i got the same problem! i tried hard reset, rom updates, other buils but it wont go away!
plz someone help us!
Hi,I'm using BOYPPC-SHIFTPDA GINGER 2.3.3 RAM_V5 works great so far the best that I tried.After u flash android it's recommended to wait few mins until it loads everything then do a shut down - not a restart.then again u wait few mins and u do a second shut down. after that the os should work fine ,at least for me works great. if that doesn't help ,try to reinstall everything from the start..hspl radio etc.
You could just turn off the lockscreen? Get 'NoLock' from the market. That should do the business if you want.
I've got the same problem since 5 days, It started when I started using WIFI and turning off my 3G ..
you have the same problem my hd2 has....it is a hardware issue. the screen becomes unresponsive. if you still have warranty send it in for a repair. if not... repair it yourself. it's not that hard. the screen wire is probably just loose.
follow this video to take apart your hd2.

Sounds like a similar problem that I'm experiencing. If I wake the lockscreen with the send key instead, it works. When I boot I get exactly one shot with the end key then it locks up again. I'm able to use it with the send key, but concerned it might get worse. If anyone finds the solution please post.
I actually for the first time had this, and I know this is going to get flamed but its not the Screen thats the problem. And I think (BIG IF) that the dreaded unresponsive screen issue that we keep reading about Majority of them I think is not the screen.
I have 2 HD2s and both have worked flawlessly without any problems, but today I was playing with my test phone that doesnt get used that much and I noticed after installing a new rom that my screen after I played with it for a bit went black (sleep) and when I woke it up it wouldnt respond, first thing that crossed my mind is I just lost my digitizier, and started wondering okay why, I went as far to re-flash WinMo stock HD2 rom, same issue, so I decided its time to find out exactly whats causing this, and I found it. I wasnt going to make a post again cause I figured people would be "Not another thread about this" but I know whats causing the screen issue, at least this is my suspicision and I have temporarily fixed mine.
The problem is HARDWARE, The Culprit: THE END KEY (Red Button)! The Answer to "How or Why": The "End" key is used to turn the phone on and off or to put it in sleep mode, it is the most used key out of all 5 keys, it is used probably 7x more then all the rest, Its used for just about everything, now how does this cause the unresponsive screen? Easy, the phone lock or sleep is associated with this key, Its the only way to make the screen go off other then waiting for the time out period. Because by habit we mostly hit the end key to turn the screen off the phone automatically associates this with locking the phone, once that happens the screen becomes unresponsive because of several reasons: 1) The contact under the actual key has dirt which causes the button to stick in the down position, 2) the contact is bent which the "end" key is pressing down on the contact which is making contact with the board and causing it to be unresponsive, 3) The contact is worn. This is the reason why if you press the end key a few times (anywhere between 2-10) and then try the screen responds, this is cause your "unsticking" the key which then lets the screen respond.
Most of us when we hit the end key press to the far right to avoid hitting the back key (The button with the left arrow) which causes the end button to lean toward the right. But you can wake the phone up with the other 4 keys to the lock screen which will allow you to unlock the phone. As a temporary fix for myself, on my test phone I now make sure to press on the left side of the key to prevent this from happening, since its a test phone I'm not worried, but the real solution is to take the phone apart and clean the underside of the end button, and the actual contact with alcohol to remove the build up of dirt and whatever else. And also if the contact frame is bent to GENTLY bend the right side back up alittle to stop it from happening, or sending it to htc and letting them fix it.
We have to RE-TRAIN ourselves to start using the other keys to wake the phone up and not rely on the end key so much.
Hope this helps anyone finally why we have this problem. And if it works for you then hit the Thanks button

"Jerky" / not accurate screen (video inside)

Anyone has this problem? When I put my finger on the touchscreen, screen moves up and down like crazy. It gets worse when I move my finger to the side of the screen.
I tried different roms, different kernels, nothing fix this.
Only when using the touchsentivity app and changing the value to any value and clicking apply makes this behaviour disappear for a moment.... after locking the phone and awake it, same thing happens again.
It drives me crazy because I always put my finger on the screen when reading something.. or in some apps or games when I need my finger stay on the screen it gets annoying. .

This isn't normal. If you can't solve this problem with a factory reset, get your phone exchanged or repaired.
Sent from my Desire HD using XDA App
That's what my HD2 used to do. Couldn't type anything on it to save my life. Think I'm gonna have to check my SG2 now I've seen your vid.
Thats probably because the custom kernel your using has a different value for it and the app is setting up 5, try it with a stock kernel and perform a factory reset and see if the issue still occurs w/o changing the TSP value.
I got the same problem. I do that sometimes too.. scrolling up and read while holding my finger down, it just jitters or something.
You're not the only one, but not sure how widespread this problem is or if it is normal or not..
Mine is also jerking when holding the finger out at the edge lol, looks retarded

Interesting...so if I disable the touchscreen fix the problem goes away. If I reinstall it, no matter what the settings are, I get the jittering effect at the very corner of the screen.

Yep I got same problem, when reading and holding down on the screen it does the same.
On Litening Rom 1.5 cant remember if it happened on stock rom though
I get this too, my SGS did it as well.
I tried this multiple times on the edge and it does not jitter at least on the phone that I have.
Mine did this when it was plugged into the mains (using a non-samsung) charger. Does not do it when plugged in via USB or on battery.
Is yours plugged in?
So some have it, some not?
I always had this thing, since KE1.. now on KG5. Stock kernel, custom kernel, rooted or not rooted doesn't matter.
Also, it has nothing to do with the touchsentivity app. The app even fixes it temporary when applying a new value, but it re-appears when locking-awaking the phone. (I tried to enable the service option on the app, so it will apply the value everytime I awake the phone, but this does not work)
I just tried it when plugged in in the changer, it seems to do the opposite... when plugged in I don't have this effect anymore. Once plugged out it starts again.
I also have SGS1.. this does not happen.

So how has this worked out for you? I have this too but just a little bit less. It also stops for me when plugged in. I wen't back to the store with it but saw that the shop model had the problem too so I decided to not return it. How about you?
I checked and it appers that i have i too. Didnt notice it till now.
It is occuring only on the left side when holding my finger.
I did not notice it too...and yes, mine is "Jerky" too...
Mine is fine, so looks faulty to me.

weird left side
I have to say this happens to me too but only when at the VERY edge of the screen,on the left.
There is something very weird about the left side of the phone.
1. the touch issue
2. the yellow tint
3. the glass is more raised than the right side(check it out) its like there is less bezel showing on the lower left part of the phone than the right side. I've checked 3 s2s and they all had it.
I have this all over the screen but not as bad as on the left side. Could someone install note everything and make a paint note with the smallest brush. Then try to make some straight lines (without the phone being connected to the a/c). Draw them really slowly from the left to the right. Mine usually jumps 1 pixel up and/or down and is a bit wavy (which isn't normal for touchscreen phones cause I tried the same thing on my friend's optimus 2x and the lines where as straight as could be). Maybe if you guys make a screenshot (home button+lock button) we could compare them and see if there is really a problem with specific phones or with the Galaxy line in general.
This was something I noticed when I first got the phone, if I kept my finger on while browsing, it would "shake" and be extremely annoying. Same thing happens when you hold an application in the left corner of the screen.
If my phone is charging, the problem is gone! It's smooth, and doesn't "shake".
Soon as the charger is removed problem is back
Going to return this tomorrow and see if they'll exchange it.
Just another 'my phone is red, yellow screen thread'. Does it affect your day to day usage? If it does,i too is concerned.if not, then what's the point in looking for non measure issues? This issue was up like 4 months ago and now, back. Y'all just return your phones and close annoying threads.

[Q] Black Screen...

Hello all. First let me state that I rather not make a thread to ask help on a problem that seems to have happened to a few owners, but my knowledge as to how I could resolve the issue is severely lacking..
At some point today my phone was ringing but the screen would not show. I thought about taking the battery out and turning it back on but there would be no HTC, Bootanimation, anything. It was Just a black-lit screen which responds due to tactile feedback and the four touchkeys light up as usual. At first there was an odd sound that would play after a few minutes so I decided to charge it but again there was nothing. Even tried to access bootloader with -Vol and Power still no screen.
I asked a friend of mine to call my phone to see if it would ring but they said it instantly goes to voicemail as if my phone was off. Note that I WAS SURE IT WAS ON.
Adb seems to work with it as it seems whatever I need to do I have to do it through there.
G2 rooted with gfree method

Again i am sorry if I bothered those with posting something others would think is "too common of a problem" as I have no experience in fixing this issue. Plus I would like to try any option available as I would not like to try and have my phone replaced (because of the risk of discovering root and obtaining a G2 with stock gingerbread which is currently not rootable)
Please help..
It sounds like you're suffering from some sort of hardware failure. You need to send your phone in for repair/replacement.

Same issue here...
I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.
It first happened a few days ago, and since i didn't reboot/restart in weeks i tried to reboot but the same issue comes back.
then i shut it down, pulled the battery and then back, and restarted: the phone goes directly to that black backlit screen, i tried several times and tried recovery with no luck, so i thought my phone was messed up although i did have some haptic feedback, well in fact the phone was actually booting, but just not showing anything else than the backlit screen; i waited a minute or so to the booting completes (still shows nothing), then i lock/unlock the screen again and there it is, asking for the pin code.
I tried to go to the recovery again to try to wipe dalvik-cache, i know for sure it goes to recovery, but with a totally black screen, not even backlit this time; the trackpad is too sensitive in the recovery to just blindly navigate in the menu, so it is not useable at all.
Then i had the idea to go to Rom Manager, i reflashed the rom from my sd-card, and enabling wipe dalvik-cache, which worked (all through a black screen). After a few minutes i "felt" it rebooting (vibrating) but still back to that black backlit screen, and i locked/unlocked it again and back it was asking pin code...
I also tried to roll back recovery to 3.0.2.4, since i remember i updated it a few weeks ago, but still the same issue.
I don't know what else to do without accessing the recovery, i wanted to try another kernel, or remove the trackpad wake... is there a way to do it via a script? I guess it's what Rom manager does...
Next step will be a total wipe, but i need to make some room on my sdcard for backup purposes first...
If anyone has an idea to sort this out, i'm highly interested...
I'll try to get a logcat, maybe could give a hint
Edit: Virtuous sense 2.0.0 (used it with no issue since it came out, could it be a hw issue?)
Edit2 : attached logcat
Is the pin screen differant than the usual one ie white number keys? If it is that's the sim lock screen you need to call the carrier to get the code or find out the default. Or just get a new sim lol
nah it's the 4 digit pin code, i didn't lose it btw, it's still working and i can use the phone, but i have a black backlit screen whenever i want to wake the phone, and thus when i receive a phone call, i don't know who it is and i blindly press/swipe the screen to answer, because if i want to use the same trick of locking /unlocking, it doesnt work as the lock button is also used to reject a call...
Maybe rip and reinstall the phone app?

I'm facing the same issue, when i try to unlock the phone (power button or trackpad) the screen lights but stays black, and the buttons are also backlit. I have to lock again with power button and unlock again to get to the actual screen.

I have the same exact problem as this EXCEPT, it's intermittent. Sometimes when I wake the phone I get an all black but backlight screen, and other times it's fine. I'm on CM7.1.
But a superwipe and reflash will probably fix it. Also don't restore system data on TB
I know i still can use wipe data + cache + dalvik through rom manager, and i always used to superwipe before switching roms, but how can i do that now when the recovery is all blacked out?
can anyone guide me to a script or something i could do while the phone is active, to tell him to reboot to recovery and flash that superwipe?
anyway i'll try the regular wipe and keep the thread updated

On my side if i leave the phone locked more than 30 seconds, it happens 100% of the time; also I noticed that now the backlight blinks 2 or 3 times (1 second blinking) when locked, first a few minutes after locking, and then randomly, about 3 or 4 times per hour; I guess it's getting worse;
I've read on another thread that it could be video cable getting loose, but since mine is still under guarantee, i won't open it right now just to check, if i can't fix by wiping / superwiping (when i know how to), i'll use that guarantee, which is one month left (lucky me)
EDIT: one other thing that makes me think it's no hardware, when the black screen appears because of a phone call or a message, the ringtone and notification sound are both half as loud as they should be, this is all really strange
after backing up my data, i reflashed the rom via Rom Manager, and I wiped data and cache (which equals to factory reset) this time: the first screen that should show the pin code numpad was already a black (backlit) screen!!
Also, thinking about it, i realised that the "flash rom from sdcard" menu in Rom Manager is in fact "Flash ZIP from sdcard": the zip doesn't have to be a ROM!!
So I tried flashing a new kernel this way, also some framework modifications (extended settings, removed TP wake, etc...) they all install Ok, but still this black screen...
Also I was about to flash SuperWipeG2.zip this way, but if it doesn't fix my problem, I will be stuck with a blacked out recovery, as SuperWipe wipes everything including /system; so if anyone has an idea to tell Rom Manager to flash two zips (Superwipe then Rom) i'll be willing to try, or a script to do that;
Maybe i'll have a look of the scripts in Superwipe and in the rom, and put both zips together... don't know if it's possible?
Maybe I'll try the Superwipe alone if I can get a spare phone, just in case...
Other thing:I used the phone's gps for more than 5 hours with the screen lit, and it never flickered even once; so it's hard to believe it's a screen connection issue...
Just to keep this updated, everything i did, including superwipe didn't change this issue, so i sent it back to the technical support (under guarantee) and I got it back today; the report that came with it says the screen has been replaced; so it was hardware finally...
Hi, i have same problem.. Black screen in recovery and during the boot. When the system boots, screen is OK. Sometimes i have also blackscreen when I want to use HW keyboard. I tried 4ext, reflash older versions of CW but still the same. I can see a screen through Android Screen Monitor and I can cotrol it. But phone is blak, only backlight. Can somebody say, how to solve this issue?
So, for other, if you cant see screen, you can use Android Screen Monitor for Windows and connect phone through USB and see a screen.

WAIT one minute... they don't care? where was I when this meeting took place?
I had this issue as well on a spare G2 I had.
The screen was just black but you could tell it was lit, hardware keys were lit as well.
The phone was actually my brothers and it rooted w/ CM7.
I ended up selling the phone as is on Ebay but after some research it was a failure in the hardware for the screen and I found extensive instructions on how to replace it that I didn't wish to do.
I never attempted to get it replaced and kind of wish I did now if they don't care about the device being rooted.
I purchased my G2 before he had his, and it's never had the issue so not sure what to think of it.

I think I have similar issue, can you post where you found those instructions?
Thanks in advance!

I used the same tutorial to change the LCD but after I put the new its just the backlight but nothing else... I will give it another go maybe and have a look again at those ribbon cables! I guess...

I found on ebay: HTC-Desire-Z-T-Mobile-G2-A7272-Slide-Flex-Cable-Ribbon
or I found also with the chassis for a bit more.
Thinking to buy this, it would be great if anyone could confirm that it would help "my condition" ?
THanks in advance!
In terms of cables, yes the flex cables are what you want.
