In Panic Mode, help please--screen went dark

My screen worked fine earlier today, then out of the blue went dark. It is as if the backlight is set at a permanent low setting. I can barely make out what is on the screen. It is not totally black, but it is by no means easily visible. I have not made any reg changes or application installs that I did not previously have.
Please help. This particular device was an insurance swap out made in November. I have tried hard resetting, and nothing. It is still a very dark screen--even the initial TMo boot screen is dark.
I am running Jaguar 3.1 by NTS.
PLEASE...help. I would very much appreciate any insight. Is my screen fried? Is it able to be fixed?
Thanks in advance.

you can try the prog Mymobiler to see if your today screen is really dark (if it´s dark on your computer too, than i think it´s a software failure) if it´s shown normal on your computer than i don´t know, maybe hardware failure...
sorry can´t help more
steph

I have that program too, and didn't even think about that. I will try it and report back. Thanks for the idea.
EDIT
Everything works fine using My Mobiler. I was able to make sure power and brightness adjustments were made-but to no avail. I even flashed a different rom just to rule out rom failure. My screen is still dark. In bright light I can barely view the item, and that is with some serious squinting.
Could it be my screen needs replacing, or is this a bigger issue like the mobo? If you suspect the screen only, could you please suggest where I can get a replacement screen?
This sucks big time. I love my Wizard and really do not want to move to an inferior device (like a "regular" cellphone, or the Wing--which is what insurance would swap me with).
PLEASE HELP ME FIX MY WIZ!!

I remember a long time ago...

The first time I have use a Pocket pc in settings I uncheck the square that say "Turn on backlight whena button i pressed or the screen is tapped".. or something, jeje every time I turned on my wizard, it hasn't light jaja.
But I think that your problem is hardware, you need another wizard to change displays... cause if you buy a new display... maybe the failure isfor the motherboard...

Thanks for your quick responses!!
I was worried that the issue could go beyond just screen issues. Does anyone know a way to troubleshoot something like this? To find out if it is just a screen, or if the MoBo is going out on me...
**Or is anyone willing to sell me their working but no longer used wizard? I can afford about $100 (+shipping costs/insurance) for a used but working device. My hubby is unemployed and I am on disability so right now money is tight.

Check ebay, you maybe able to find a working phone for 100 bucks. Gook luck!

have you checked the wiring (flat cable) that connects to the screen.
maybe you just need to replace that. if the screen works, then it is just the LED's that are not responding. maybe just a loose connection, or a broken contact.
Does the keyboard light up?

i think i have the same problem or at least similar.
my screen backlight goes black from time to time when i press the screen "too hard", but that comes and goes.
interesting: i'm using homescreen plusplus (ex-batterystatus) to overclock my cpu with the option "set cpu speed at wakeup" activated. when i turn off my screen with the power button and then turn it on again, in most cases my backlight turns on, too.
but that's to enerving for me to live with that, so i disassembled my wizard and found some sort of black dot on the flat display connector. maybe it has something do with that? and if so, where can i get such a flex cable?

I have the manual--I used it when my usb was fubar'd--but I am a bit intimidated about doing something with my screen. Is it something that can be easily screwed up if I even look at it funny, or can I handle it carefully and not worry that the mere act of touching it will make it explode??!!
Perhaps I am being a bit dramatic, but you get the idea I think.
Do I have to be totally grounded out first? Do I need gloves on? Or do I just rip the dang thing apart and go at it?
Thanks for your help and responses.

You can get an anti-static kit in Radioshack!

Well I don't have a Wizard, so this might not be much help; however, I have had a similar problem with my Touch Elf after installing a new app. The dark screen did not appear until I performed a soft reset and I really started to panic because there was nothing I could do to change it. I could barely make anything out that was being displayed it was so dark. Even when I turn my screen brightness down it was not ever that dark. Just out of luck though I pluged my phone into my computer VIA USB and voila, the backlight came on. I could use my phone again and immediately navigated to my brightness display settings and turned it all the way up (it was set all the way down for some reason). I have not had this problem ever since. I don't know if you have tried this already or not - It was not mentioned in any posts.
Good luck

Check out eBay for a replacement LCD, I got one last week for € 32,- ($45,-) including the shipping costs.
BUT...when buying from eBay notice the following 2 things:
1) The screens are most of the times used screens with a new (hand-soldered) digitizer on it (but it is done nicely as far as I have seen).
2) Disassemble your Wizard, check if your LCD has a BLACK or a GOLDEN flex ribbon cable at the back.....when you purchase the wrong one, it will not work!
An alternative is just to buy a 2nd hand Wizard for like $70 / $80, buy a new housing for it ($40) and it looks brand new (except for the LCD, most LCD's do have some scratches on it).
A HTC Wizard Service Manual can be found in the Wizard section on the XDA Dev FTP Server (I use it a lot), sometimes when buying a LCD on eBay they will also send you the tools needed to disassemble and reassemble the Wizard.
Good luck!

I can furnish you with a flex cable for $15.00, plus $5.00 for shipping. Let me know if you have an MDA or 8125.

LCD Screen Defect or Software/Driver Problem?

Hey guys,
I am going crazy here, searching forums did not help me at all.
The lower section of the screen keeps flicking, and not always, what do i mean by flicking, its like the screen at the lower section keeps doing like a strange low refresh rate, and has an old imprint of some old menus. Happens especially when there is the color of gray.
Made a screenshot of the phone, no problems, there, so its not a software rendering problem, might be a drivers problem though, or a defec tin the screen itself.
Frequency is high but not always, and am unable to determine when does that happen exactly. going crazy here, is this a defect? or all touch pro's have this?
Exact explanation summary:
1CM from the bottom of the LCD sometimes flickers as if that 1CM is having an extremely low refresh rate. Mostly happens when there is light gray, but not necessarily, and a soft reset for the phone does not remove it. It happens on random!

Hey,
Yeah it happens to me too! You don't need to do a soft reset, it actually fades away if you watch it closely! I don't know what it is either, and yes it is random as you have stated! I initially thought it was an application I installed as it only started happening after that, so I did a full hard reset and its still happening! Not sure what or how, but hoping next firmware version stops it!
Cheers,
mpls-te

As it happens, that's exactly why I've logged on here today! Any ideas whta the cause might be?

OK, good to see that others have this, so am not alone here, experts here, any ideas? other touch pro users, can you please leave your statements?
I hope its a driver issue.
But from what i noticed, its like, the screen is OFF, as in blank and no back light, but somehow, the application working on the screen before you turned off the device is somehow printing something on the LCD, something that we don't see, and when we actually start the phone and its back light, that OFF LINE imprint pops on screen. Something like that.
Its completely illogical, but dunno, can't find any sense here and am going crazy

Same thing happened to me and a few others as well.
See my thread here.
What rom is everyone using?

I've noticed a similar issue with mine, except rather than something software it seems like it's the backlight for the bottom 1cm of the screen flickering slightly. I don't see any weird pixels or inappropriate screen information, just a dimming/high speed flickering of the backlight in that same regionas yours. It comes and goes. Sometimes weeks without it, then maybe 3 times in a day for a minute or two at a time. Everything else works fine and whatever screen I go to displays fine.
I'm assuming it's a hardware problem with the LED(s) that light up the bottom portion of the screen, and I'm going to use it as an excuse to get a warranty replacement somewhere near the end of the warranty when the phone's getting a little old and worn.

Lool, evil, lets just hope that this problem DOES occur when you go to their shop for your replacement
Good idea though, might do the same thing except that i have to travel abroad to where i got the phone from to actually get the warranty working. Don't forget to re-enable stock SPL and stock ROM

It happens frequently enough I'll be able to get it on video just in case they need proof, but typically they just exchange by mail.

I just posted in another thread about this issue. I have run into the same thing a few times. The bottom portion of the screen flickers, and when i do things that have a dark gray or black screen I can see a ghost image of the left and right soft keys from my TFL3D home screen. It seems to be most noticeable when the screen brightness is set to max. To get it to go away I usually do a few soft resets, and then, if needed, i will turn off the phone and take the battery out for a while. I have never tried waiting it out to see if it will just go away on its own.

I see that everyone posting in this thread,that has their signature filled in, is using the Energy ROM. I find that very interesting.

i am having the same problems, sometimes touchflo3d will flicker at the bottom, near the edges. I also get text that can be read through other screens. Like on pocketshield i can see the left and right softkey words still at the bottom. its so odd !
P.S im on energyrom

I'm on NATF v2.2, not an energy rom. But then again, mine looks more like a hardware issue, as I've never seen any ghost images of text or softkeys, just flickering.

can somebody post screens?
maybe the same problem here...
hardreset, other roms > problem still there:-(

Same problem here and I am using stock rom!

here are 3 screens of my xda diamond pro, using latest official o2 rom and newest romeOS eng
hope you can see this prob?! same like yours?

Well, i doubt EnergyROM has anything to do with that problem, since my Stock ROMz had same problem, never got fixed with any updates HTC used to release. MAYBE some Cooked ROMs out there have this solved, if any, please let us know And my problem is nothing close to screenshots above :S

Dude, those photos are awful, after seeing them am happy with my phone flickering, its nothing close to this.
You see, in your photos, all three of em, you some kind of shadow effect, where text of a button for example has that same text beneath it 3x6mm, that is not my case at all.
My case is as follows, IF i am on the home screen for example all looks ok, except that the bottom 1CM of the screen is flickering. If i go to another window, either a total black one or any other screen, i would still see a ghost of the old home screen, for example, and only at the bottom 1CM.
Will post photos once i get my cam back. Cheers

similar issue
my issue is kinda similar, instead of getting the bottom 1cm or so discoloration or stuck pixels, I get streaks of red or blue on my screen. I have had this happen on each version of NATF I have tried, but don't remember it happening on the stock version (which I am tempted to try again to see if that's the issue).
Could this be a driver issue?

mind is even worse than all you guys, the touch screnn dose not response, and i have the energy rom on it, before it goes wrong. it just suddenly dose not response, than i send it to HTC, they ask for 425.00 for fix.... I will just send this to Asia and get some one to fix it.
But I hope before i send it out, some one can help me here.... anyway can fix it easy!!!!

Hi all, i have the same problem, here's another topic about it

[Q] screen disaster - random tinting, solarization, turns upside down

sooo, yeah. my wife has the t959v. the screen cracked months ago, replaced it with one from ebay, works fine. a few weeks ago, it was involved in an accident and needed yet another screen replacement; ergo, back to ebay i go. installed the new screen yesterday, turn it on, all is well. for a bit.
now, the phone isn't currently, nor has it ever been rooted; pure stock tmo us 2.3.6. during boot, the splash screens and boot animation are gorgeous and perfect in appearance. the recovery menu is exactly as expected. android boots as you'd want it to, and then the display will do one of the following:
-work properly (rare)
-automatically turn off, capacitive buttons still lit, touchscreen unresponsive - turning it "off" darkens the cap buttons, turning it back on flashes the screen on for a half-second, then off, with cap buttons still lit (common)
-graphical corruption ("solarized" colors, completely wrong colors, pixel vomit in essence) (fairly common)
-screen tinting, blue most often, followed by pale yellow, then greenish, then red (almost constant)
-screen inversion - the display will show as rotated 180 degrees; grabbing a framecap in ddms shows it right way up. touches are also inverse; you have to touch where the onscreen element would be if it were displayed properly instead of where the element is; e.g. a button on lower-left will display in the upper right, upsidedown, but the screen registers the button when you touch the lower-left portion of the screen. (quasi common, equally infuriating and hilarious)
none of these problems will show up in a screenshot at all.
i can reliably reproduce any of the above by simply adjusting the screen brightness. this will, quite literally, cycle through every possible defective display mode randomly for a split-second before moving on to a different one as long as you move the brightness slider.
MOST of these issues are transient and are either fixed (temporarily) or replaced with a different listed issue if you lock/unlock the display. it feels like a hardware issue what with the solarizing and color horrors, but is acting like a software issue, considering that recovery and boot are perfect and have never displayed any of these issues. i tried gently flexing and stressing the case in areas that might be a weak connection point, but can't get it to bug out that way.
in no way am i suggesting that i didn't screw something royally in the reconstruction stage, but i tore down and rebuilt that phone 4 times with identical results, so i can guarantee it's not some loose ribbon connector or zif socket.
i beg of you, great minds of xda, what the balls did i muck up this time? any hope for a fix? are there different panels, drivers, something?
thanks in advance

OK, if your screenshots appear normal, then your phone appears to be working correctly!
or at least it thinks it is we can conclude that it isn't the rom, kernel, or anything that you can blame the phone for going screwy.
Try buying another screen??
The ribbon connector might be broken?

yeah, these were what i figured what my options were. it just seems odd that the boot process and recovery menus have error-free displays while only the full android os doesnt. oh well, i'll probably just have to make a stink about it on ebay or something.
thanks for reading

You might try a fresh flash before getting a new screen to see if it is indeed a hardware issue. If you want to try that follow the second link in my signature. You will not need to flash bootloaders since you are currently on KJ6.

hell, warranty's void at this point anyway, right? may as well thanks much!

welp, all went well, screen was perfect through the whole heimdall/recovery process, but the problems still exist in the os c'est la vie. at least my wife's phone is finally rooted, i suppose. thanks anyway!

Have you tried opening it back up and reconnecting?

yup, 4 times, but i guess one more wont hurt
[edit]
it definitely seems to be related (if not related, exacerbated by) changes to screen brightness. turning off autobrightness has helped minimize the issue, but it still presents itself semi-often during screen-off/on events. obviously nothing useful in logcat.

That's interesting and could very well be a hardware problem with the screen. You wouldn't see that in recovery as the OS isn't loaded to mess with the brightness in that mode.
Does it do it on-demand if you mess with the brightness slider?

you better believe it does. rapid fire cycles through every color until it can't take it anymore and turns off. if i take/refresh a screenshot through ddms and poke blindly at the screen at that point, it'll still take input which is a curious, difficult game to say the least.

It's that Pink Floyd screen. You're supposed to drop acid & watch the wall when that's going on. LOL j/j
Given that you're on a fresh ROM & the problem persists, I'm leaning toward a hardware issue man. Sorry.

as fun as that sounds, unfortunately i bet i'll end up just getting my wife a used phone on ebay or somewhere similar and using this one as a development monkey. i was assuming that it wasn't something i could fix but hoping otherwise... yeah, that worked out

I just started having this problem. It wasn't too bad at first, just the color changes, but then it started not showing a screen at all. Changed to three different roms, even back to the stock non-rooted KJ6 and gave up. Keeping it on a steady brightness is the only way to minimize the color changing. I thought your thread had a solution but...
I may try opening it up and fixing the ribbon. But otherwise I'll keep using it as long as I can tolerate it until an S3 or a new Nexus.

nawp, nothing even close to a solution here i did end up buying my wife a whole new replacement phone and turned the broken one into my api10 development device. for what it's worth, yeah, autobrightness off does help a bit for when the phone is actively displaying content, but after you put it to sleep/screen off and try to turn it back on, it's a crapshoot. for a few horrifying hours, the screen was upsidedown even in recovery/boot animation and would NOT flip back to right-side-up until i ran the battery completely flat.
is no fun, 'tis truth. sorry for your troubles.

Proximity Sensor intermittent

First time poster, though been a regular lurker.
It seems I have a slightly dodgy proximity sensor. Have checked with one of the proximity sensor apps and while the sensor detects if I have my hand over it, it is very unreliable when I take my hand off. It can take from anywhere from 1 to 30 seconds or sometimes never.
While ive been through other threads where people have a completely failed sensor, does anyone have this intermittent problem. Also is this a hardware or software issue.
Im currently htc-dev unlocked running Pacman v15.0.

Out there is a tool for recalibrating the sensor, but you would need to be S-OFF I think and it's done with a service tool (a special PG88DIAG.nbh)
Let me know if you are willing to try it, but it is VERY dangerous if you do the wrong things.

I had the exact problem from the very beginning. Got a phone and the very next day had a screen protector applied. For a few days proximity sensor created problems. The screen would go black when the call started, but until the call did not end, there was no way to bring the screen back. So, I used an app just like yourself to check and saw the same thing happening. Ultimately read extensively and realised it was due to screen protector. Took a scissor and cut off the protector above the sensor. A few months later when I had a new protector (of a different company) applied the same problem reappeared, so I had to cut it off from the top. Except that this time around I was sort of expecting it. I hope this help! :fingers-crossed:

I had the same problem and it continued no matter whether i remove the protector or cut the portion....im unable to most awesome ROM's.......only n sense 4.0 im able to re turn on the screen using power button.if there a way to completely disable this turn off during calls irrespective of the ROM its highly appreciated......
Looking forward for the solution

An update to my situation.. I ordered a new proximity sensor on e-bay and have replaced the same on my phone now. While I was at it, I cleaned up the window as it was pretty grimy and could have been the source of trouble. Also cleaned up the contacts with Isopropyl alcohol. End result.. Im still having the same problem!!
Im pretty sure now that its not a hardware problem and has to do with the calibration. What I have noticed that the sensor works fine in bright sunlight but not when there is less light around. Also am not using a screen guard!
Would it be possible to guide me to the right tools to recalibrate please?

Sorry, I haven't done this myself, but I'll search a bit how it's done by HTC.
They are using a special holding station where the devices are calibrated.

[Q] I Screwed Something Up

A friend of mine had a Galaxy S3 Amber with a broken (and blank) screen and wanted her data from it's internal memory that is locked and not in debugged mode. I did a lot of research and found the best, most efficient way was to do a motherboard swap with another gs3. I had a Galaxy S3 Blue. I watched a couple of videos and it seemed rather easy. I gathered the proper tools and was EXTREMELY careful not to break or rip anything (and to my knowledge i did not). When i put her motherboard from the amber one into the blue one and the screen would not come on. My first thoughts were it must be her motherboard that went bad. Well when i went to put my blue gs3 back together (again being very careful this entire time) I'm now having the same issue as she was. Black screen, no back light. The bottom lights DO come on and i feel it vibrate when i get a message. There was also no power on chime...
I know its hard to tell with out looking but any ideas on what could be wrong or what i might have screwed up? i checked all the connections and everything looks perfect. Nothing is bent or connected wrong and I didn't force or break anything.
update: so i found that the touch part of it still works fine. i can hear the ripple unlock as well as all the other sounds and such when i touch around and i can here it opening apps. the only issue lies in the screen itself being blank with no back light what so ever,

First of all remove the battery and attempt to power on, then leave without battery for 1 min, I know this sounds silly but it worked on an old iPhone 3G so anythings worth a shot.
If that doesn't work go back into the S3 and make sure all the data clips are firmly in place and locked down but not twisted in anyway. Also make sure their is no moisture or dust on the ribbons. You may not realise it but even the smallest imperfection with this can cause massive issues down the line.
If all else fails her phone may have broke your screen, I don't know how but it is a possibility
Hope I could help and good luck

so i took it apart again today to double check and clean everything and under inspection i noticed a teeny tiny slit on the edge of the lower, bigger ribbon. i know the smallest bit could be horrid. Any fix and would that cause just the screen to not show? i don't know if that is the led connection but i think it may be.

Any fix and would that cause just the screen to not show? i don't know if that is the led connection but i think it may be.

If theirs a slit I'm affraid that could be it for the screen, like I said even the smallest imperfection can cause massive issues. The slit is probably in the one of the data sections of the ribbon cable which is why data for the screen isn't being carried.
For the fix I don't think their is one unless you can fit a new ribbon on to yout S3's screen
Sorry about the screen

So I took it all apart again. Cleaned ever little thing I could and now it works again. ?
