yeah your display is broken, you need to replace it! Maybe you can dissemble it to look inside, maybe there is a cable free. But when you do that, it's at your own risk and you'll lose any warranty!

yes their is no color or nothing and thanks for the advice much appreciated you backed up what i had orignaly thought thanks

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...
Think about it...

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.

somethings wrong with my wizard

hey...so i think there something really wrong with my wizard...
when im just using it sometimes when i switch it off ( not ike completly just press the button once...) and then when i want to switch it on again it doesnt work...! its still on cuz the green LED still works but i get no picture...so i have to take aut the battery and restart it...!
whats wrong there<???
and then i have another problem and its that sometimes when im starting the wizard again after that happened it turns to white screen after the second boot screen (but its not the same moment every time...some time between the second boot screen and till its started up )...or there are wired stripes on the screen for a few seconds and then it restarts...or sometimes it just stucks at the 2nd splash screen or some other time during starting up...
i already switched the rom so i used crackings 6.1 rom before now i use his 6.5 rom...
i thought it could be the cpu??
i runned it on 240 or 252 for like 6 month now...
does anyone know how to fix that or is there no way of fixing it?
thanks so far

Open the phone and check the connection between the mother board
and the video (its the push connector on the back of the MB) if its tight
you will have to take the lcd section apart ,the other end of the ribbon
cable goes to the lcd and digitizer its a tab locking connection with clear yellow tape over it. check and see if its all the way in ... if that don't fix it get get a new LCD/digitizer from Ebay .. it plugs in i one piece ...
then your off a running ... id watch the over clocking too ... when you
OC the cpu everything runs faster and heat builds up and can damage the phone .. i have seen several OMAP versions here that OC when needed
and return when the phone is idle ..
thats my 2 cents worth on that

If you are sure that your problems are not rom specific (you faced the same problems with different Roms?) then maybe this is the solution for your problem .
Good luck finding what's going wrong.-
Same thing has started happening to me. I just press the reset button and it restarts just fine. I don't see why others are thinking its a problem with the LCD. A reset shouldn't fix that (I'm guessing).
ave you checked the battrey?
ya so the problem i have is not the one descibed in the video...
its differnet...the stripes are ther not the whole time ...it comes sometimes and then there are these stripes and then the screen turns slowly white...and then sometimes it restarts or its just stays white...
and when i normaly switch it off then the leds are still working just the screen wouldnt turn on...
so i really have no idea whats going on there...i tried to make a video but now it didnt happen for almost 4 days so i just hope that its not happening again...
but its really wired and i think its the cpu cuz i cant think of another reason for that...

Orbit 2 White Screen need help.

Hi all.
I recently came into the posession of one of these awesome devices.
my only problem is that when turned on, the screen comes on but is just pure white.
the device seems to boot up ok as you can hear all the noises in the background, also the digitizer works as the backlight comes on when you touch the screen and you can hear windows mobile clicking away.
could this be the lcd thats broken? or could it be an issue with the mainboard?
anyone have any ideas? or have had the same problem?
i just dont wanna go out and buy a new screen to find out thats not the problem lolol.
(btw i have tried hard reseting multiple times and that dosent seem to be the problem)
thanks all.
Um how du know that you have HR properly if you cannot see the screen, or can you see it on the HR screen?
Also if you can can you see the bootloader, and have you tried a different rom, never know it may work
heya chris, thanks for the reply.
reason i know it has hard reset ok is i used a htc touch next to it to guage where the setup screen (screen calib etc) buttons were and tapped on the digitizer unitll it got to the main screen and reset itself after customisation (took friggin aages to do that lol)
then managed to fudge it to get media player running by using the arrow buttons etc.
sayin that what combo of buttons do youse to HR. ill give it a try if theres another way ;-)
For me its ok and windows key, the one beneath the send and end keys
Then when booted it will say "blah" and press send to restore. Press send then it will take about 15 seconds or so to restore then it reset's and boots up again.
To do the bootloader its the camera button and reset, but i dont know if thats helpful if you cant see the screen!!
Um is it still under warrenty if so go that route and if not try taking it apart and then try to see if any of the screen connectors are loose i think that someone has done this already on here with pictures if you want some help with it.
tried the hard reset again and still met with the same white screen. dang...
as for warranty, its an ex business phone i got through my work so no warranty, and i have since stripped it down 3 times to look for faults.
have tried slotting the ribbon cable in and out of its socket and had no luck.
hmm i would say maybe new motherboard or screen, which you prob already know by now.
Apart from that im out of ideas as to what to say would be a solution for the problem with it or how to fix it without replacing parts
cheers for all your help chris.
i think ill just have to take the dive and order a new screen.
god i hope its the screen lol

Phone screen won't come on!

I'm not sure if it's lag or what, but my phone screen won't come on. I think it's a ribbon that was disconnected or something though. For about a few hours if I were to press power to see the lock screen, all I saw where a bunch of rainbow static. Then I powered my phone on and off because nothing would work and now it's jut black! Does anyone know what's wrong? I can't boot into clockwork so I don't think it's a rom problem. Does anyone know the problem or have any idea to fix? Anyone I should ask specifically?
maybe water? even having my phone in the bathroom while i take a shower cause me that
It's not water, I never bring my phone close to place with water :/
can you boot into the screen where there are 3 droids with the skateboards? (i not sure whats the name)
I think I can boot and my phone still works, because it still rings when someone calls and it still vibrates when someone text it, but I just can't pick up or reply (because the screen won't come on). I should be able to boot into that thing, but I can't anything :/
well bro sorry i cant help you :/ maybe it could be the screen,the ribons or somethings loose. did it fell?

Seems like either broken ribbon that connects the screen to the "motherboard', or dead screen itself. That's exactly how 1 of my phones died (it was too complicated to disassemble and fix it myself)
But once I had similar problem with my TP2, the screen first become unresponsive to any touch, and then it went just black after restart (and every next restart). However all keys did work.
Hard reset somewhat helped, the screen actually came back, but it was still stuck on setting up Windows Mobile (if you know WinMo: the part where you calibrate touchscreen), apparently "touch" part of the screen didn't work.
I thought it is ribbon or screen assembly, but since all the keys worked I flashed another ROM and what do you know: all problems went away. It worked fine for as long as I had it. I never figured out what caused it/was the problem.

Yea I think that's the problem here. I think I'm just going to borrow a friends mt4gs to use and navigate recovery and do a back up and just buy a new one and restore. Thanks for all the help guys

Nexus 5 Black Screen, But Still Working

So my Nexus 5 (a couple months ago) has started to just randomly go black. I get notifications and stuff, and the backlight but no display. Not sure what to do or what part to replace. Would flashing/rooting help at all?
Appears to be a hardware problem.
Was the phone every dropped or exposed to water/moisture? Possible loose connection inside?
No way to tell for sure if the phone needs a new screen unless you are able to test the motherboard in another N5.

It's been dropped a couple times but not like any major drops or anything. Im pretty sure I checked all the connections inside and they were good. Im starting to figure out that the phone has to be off for a little bit then I have to charge it and turn it on and it works again
Sounds like it could be a damaged lcd or lcd connection. If it can work after being charged while powered off, could be battery or USB flex cable issue.

Ya I figured out I have to reboot it a bunch of times then it will work
I think it might be the battery because this is my dad's old phone so it's been in use for a solid 3 years.. I wish I knew for sure though
So I have discovered that if my screen is on for a while the task bar at the bottom starts to shift up and down
Have you found out more about this? I think I have the same problem. My phone never turns black while I use it. But when the screen is off/sleeping, it sometimes won't turn on again. So a force reboot fixes it. Sometimes this happens a lot, some times it works fine a whole day.

I could also mention that this happen every time I unlocked the lockscreen on stock ROMs, and custom. But nameless ROM for some reason got it to this point at least. If any one have black screen on unlocking the block screen, try nameless rom...

Maybe, I don't think so. My phone was useless, black screen on every screen unlock. But namelessrom took that away, so that tip about nameless was for those who have the same black screen I had earlier. But now I have the same black screens as you do. Anyway, if you want to try it out, nameless-rom.org

Happens with my nexus too. The screen goes blank randomly ..... But i have managed to deal with it.
Its happan to me also, with 4 nexus 5 of my family.
Is a firmware problem?
I'm trying to buy a new flex cable to see if it will help I'll update when I find out
You're replacing the USB charging flex cable? If you are, be careful with cheap third-party replacements as I have read reports of people having issues with charging, signal, or speaker functionality after installing the cable.

Ya so i sent it to LG finally and the diagnostic said that it was a flex cable issue which I was sure that it was anyway but I have a confirmation now
I've had a similar problem when my display suddenly started failing. First, there was colourful bands over the working display, then colourful static only and then black with backlight only. Bought a new phone, left it for a year and today after digging in the phone for a while I found a fix. The connection between the motherboard (the top bit) and the daughter board (the bit below battery with USB and connection to display) was somewhat loose and when pressed on, the display worked beautifully. I stuffed the insides with some tape to maintain pressure on the connection and phone works great.
Might not work for your problem, but it's worth a try if you're out of warranty and have tools to disassemble the phone.
