I've used XDA for all of my phones, dash, tp2, HD2 and I appreciate all the help. My son has a Dash and "all of a sudden" (you know how kids are) the screen is only white. It currently has the latest Energy Rom 11/2009 release. I tried manually getting into bootloader mode by taking out the battery, putting it back in then holding down the camera button while I plugged in the usb. The screen stays white but Windows Mobile Device recognizes the phone. I tried flashing Energy Rom again but get error 270, again the phone never goes into bootloader mode the screen stays white. I also tried getting into bootloaded mode by just holding down the camera button and turning the phone on with no luck. I downloaded MyMobiler and can see on my pc screen what I can't see on my son's phone. Using MyMobiler I managed to "Clear Storage" (Hard Reset) but the screen still stays white. Any ideas? I appreciate all your help!
I think it's hardware, something on your lcd maybe loose.

More than likely need to take it apart? That sucks! The LCD lights up, but nothing is displayed. Anybody else getting this?

I think so, since you can view your screen through MyMobiler right?. Try to reflash your stock rom, if that doesn't work....that will sustain my diagnosis.
Good Luck

If your screen is white then the lcd cable probably is not seated all the way.
Follow this guide and just reseat your lcd cable instead of replacing the lcd screen.
What about the "crazy" posibility of water damage? Have you checked the sticker on the battery?

Thanks for your advice guys! Yes I can see the entire phone on MyMobiler, the buttons work and all.
I thought water damage at first but the indicator is still white.
I'll start taking her apart, thanks for the responses.
if lcd is not broken its most probably the flex ribbon a little loose. i have seen this a lot on this device. be careful with the housing, it can brake easily.
(I posted this first in the Desire Z forum. I didn't realize there was a separate G2 forum. I even looked for it.)
I've had my G2 since the 9/29 and on several occasions I've noticed the trackpad triggering itself when my finger is no where near it.
Once, I was in the market looking at a list of apps. Normally, when you swipe on the trackpad in there it selects an application and highlights it orange. This randomly happened all by itself. If I touch the screen the selection goes away, but then it would suddenly appear again a few seconds later.
In Subsonic it even jumped around between a few controls.
Another time I was playing Wordfeud and it spontaneously highlighted the Pass button. This time I grabbed my old G1 to shoot video of it happening. I must have shot at least 10 minutes of video and it happened twice more, as I recall.
Update: Here's a video of it happening on the home screen: http://www.youtube.com/watch?v=b9-Yu4DSimw
Anyone else have this problem? I can't reproduce it at will. It seems to happen randomly while I'm holding the phone.
naw, but i've noticed my trackpad will occasionally bring my display back to life when it's timed out - will not do it predictably, but 2-3 times out of 10 tries, it will
have no idea what's going on, but would love to be able to use it to wake the phone up - much easier than using the power button
Hmmm, I have my phone plugged in via USB right now. I have debugging turned on, and "keep screen on" enabled. So it sits there dimly lit after 2 minutes. I was going to leave it alone and see if the trackpad spontaneously moves when I'm not holding the phone.
So far it has not, but just now the screen lit back up to full brightness all by itself. This normally happens when you touch the screen, a button, or the trackpad.
In all previous cases of my bug, I was holding the phone. I heard that the trackpad is capacitive, just like the screen, so maybe holding the phone a certain way can mess with it, but sitting on a desk it won't. If I let the phone sit here long enough, maybe I can refute that idea. If a home screen icon suddenly becomes selected, I'll know that it can happen even when I'm not touching the phone.
In any case, I can't explain why my screen woke back up from being dim.
Yea the touch stuff is set off by heat so maybe it felt some heat from somewhere and thought that you touched it. Thats about all i can think of on that one.
I'm pretty sure it's triggered by electrical capacitance, not by heat. It's either optical or by capacitance (and I heard it's not optical). I don't think any sensors like this use a heat detection mechanism.
To test this, you should be able to hold something cold with a similar capacitance as your skin, like a cold hot dog, and operate the trackpad using it.
See: http://en.wikipedia.org/wiki/Capacitive_sensing
Yes , I noticed mine doing the same thing. If my finger were to hover anywhere near the trackpad it would flash and move around. It doesnt happen all the time but it has happened. I also have had some issues with the sim card and memory card not being read. The memory card I had to put it on my pc transfer all the data, re format and scan the card then reinstall my data to the card. Which has fixed the issue. I suspect a download from the market may have corrupted my memory card.
G2 running stock 2.2
My_touch Slide
rooted
2.2 Cyanogen 6.0 kanged
As promised, here's a video of it happening: http://www.youtube.com/watch?v=b9-Yu4DSimw
So, at first I thought the trackpad was optical, but someone on reddit assertively said, "no, it's capacitive." So I believed him. But now I think he's wrong.
I believe that if the trackpad is capacitive like the touchscreen, then anything that can interact with the trackpad can also interact with the touchscreen. I used a piece of cloth to interact with the touchpad and it did not interact with the touchscreen.
Here's a video I just made: http://www.youtube.com/watch?v=zYaSzwZGlvY
(Shot with my G1) The cloth easily moves the trackpad around, but it's impossible to get it to register a touch on the screen.
Also, the trackpad is perfectly usable even when your finger is completely covering it. Try it with your thumb even. You can completely cover it then still move around your thumb and your selection will move around. I do not believe a capacitive device would detect the difference between full contact on one place on your thumb and full contact on a different part of your thumb, and especially not the direction of change as you move it. Capacitive touch screens rely on moving the point of skin contact, which never happens if you're touching the whole thing at once. An optical sensor on the other hand would be seeing your fingerprint move.
Thirdly, when you look at the trackpad in direct light, it looks like dark, transparent, purple plastic. I believe it's transparent yet purple because the wavelength of light it emits can go through the plastic, but is not visible light. Infrared maybe? Ultraviolet? I think it's very similar to the "black" CDs for the original Playsation gaming console. They were actually very, very dark purple but that was completely transparent to the CD player.
See a photo: http://i.imgur.com/SpIIZ.jpg
Fourth, I can't get this bug to happen if I hold the phone perfectly still. It only seems to happen when I move it around in my hand. I think the sensor is "seeing" movement when I do that.
And here's the proverbial nail in the coffin: http://www.youtube.com/watch?v=GOQukQxwajg
Electrical tape doesn't stop a capacitive touch screen, but it renders the trackpad useless.
It's probably a simple IR LED and photodiode operating in much the same way an optical mouse operates. One way you could check is to point an old camcorder at the trackpad. Old camcorders tend to have weak or no IR filters.

My old G1's camera has no problem seeing the IR from my TV's remote, but it detects nothing coming from the trackpad. However, the remote is designed to reach a lot further than the trackpad, so maybe the trackpad's LED is just very dim.
I don't have anything else to test it with.
yes, i have had this problem!!...it did it on my home screen, just starts switch home screens left and right...this was like two days ago...it hasn't done it since,still debating if i should get a new phone
The trackpad is optical/IR. It responds to infrared. If you go out on a sunny day, your trackpad will go wild. The new blackberrys have the same problem. I really do not think there is a fix, and it's pretty annoying. I've owned a Blackberry 9700 since January and I never could find a way around this, no matter what sensitivity setting I had it on or how much I updated the OS.
I've noticed the same thing with the G2.. in sunlight, the cursor goes crazy.
If there were ever any sun in Rochester, NY I would test this. I assume It's only a problem if the phone itself is in direct sunlight. Is the the case? So, if I shield it with my own shadow I'd be ok?
Sent from my T-Mobile G2 using XDA App
I just noticed this with my G2, kind of annoying, ha. So I experimented and found that nothing happens while holding the phone still or while it sits on the desk, or with the room's light off. But, if I tilt it around with the light on, it acts up.
I think it's detecting the light behind me.
i think its kinda cool. doesnt bother me cuz it makes my phone feel.... alive in a sense. but it is very light sensitive. im freaking loving this phone. not a single complaint
I know theres a similar thread with only 4 replies.
a: i re opened the phone disconnected and made sure the screen was properly conected.
b: yes the buttons do respond to touch
is there a piece of code or something that will re enable the lights to go off. Ive had issues with the phone before thinking it was the hardware but it was indeed code...(i.e charging port. on and off button) thought it was the hardware but it was just bad code...
has anyone seen this and been able to make them light up again?
thanks!
You probably damaged the ribbon cable, they are very sensitive. If they still respond to touch, that means only one of the contacts is bad.
I know the answer
I have wondered the same thought but I have found the answer . I replaced ky EVO screen 2 months ago . It was glass only replacement first time for this device. So got the whole thing apart and connected it. successful onto Tue touch and all but i notice the lights so taken a look at the of screen their are clear caps under the touch button and the cap had a tail and it lead to device and it is where the light is in the device so I took each cap off and cleaned it up and put it on at first no epoxy or holding agent and i got the light but i suppose if u use a clear epoxy at the bottom of the screen it may have desired effect
Recently I returned my Razer because the vibration in my phone sounded horrible. Over two weeks later I got a replacement phone back and the vibration ended up sounding even worse than the first so I just assumed they're all this crappy. Then one day later after setting up my second Razer phone this happened.
The screen went black and clicking the power would vibrate but the screen wouldn't come on until eventually, it appeared as you can see in my screenshots. I managed to factory reset it and even after it still appears cut in half until finally, I was able to power it off again and restart, which after it seemed fine for a bit before the entire scenario replayed itself. Has anyone else experienced anything like this?
Obviously abnormal behavior. I'd try another rma
Can confirm that mine does a similar thing. Every now and again left half of the screen would freeze. It happens for a few seconds and comes back normally. I saw it first about a week ago, but thought it had to do with a specific app. Since then I had it happening in other apps and home screen.
Can't say I've seen this, and that's from 3 phones. Have yet to update to the new firmware yet though.
I have seen that with some company's laptops before and generally its had to be put down as Dead on Arrival as usually caused by some physical damage to the screen. With phones I cant say I have ever seen it happen on a small screen but certainly get it sent back as from 10 years in repairs I wouldn't see a software fix for that type of screen issue.
UPDATE
Mine went from having left side glitch occasionally to the who screen turning back every now an then. Left side is mostly frozen. On the bright side, I found that if you apply some light pressure to the middle of the bottom grill you can get the screen back pretty reliably. Judging by disassembly video it is where screen cable is bent to go under screen assembly, so it is probably result of some stress/tearing of that cable. Would explain partial malfunction as opposed to complete failure, but I can obviously be wrong.
Also, RMA was granted without a problem after we tried a factory reset with the tech.
RMA would be the best bet. I am surprised by the defective stories popping up, but at the same time I don't think I've even counted 100 people that have had a defect requiring an rma. And we know they sold at least 1,337 of the phones, so that's still a decent failure rate.. Though I think they need to revisit it and get that number lower.
yeah without question send it back to the store as dead on arrival or rma the phone - sooner its sent back the better with laptop screens doing this 9/10 times was the screen was broke and mainly a loose cable or dropped by the user. 1st 30 days or so the retailers and laptop manufacture could replace them but the longer it took to report it the more inclined to treat it as damage and not cover it under warranty.
Yes im comparing a phone screen to a laptop and normally a loose or damaged cable would show signs of this, Could be temperature related as well.
It was pretty much dead on arrival it's just annoying to have to go through another RMA and the whole 2-3 weeks before getting another replacement.
Also whoever mentioned squeezing the bottom speaker is correct that temporarily fixes the issue.
My Razer phone screen has failed
I've owned the Razer phone for less than two months. Yesterday, I went to wake the screen from sleep (press power button). The phone displayed random black and white bars pulsing across the entire screen. I was unable to interact with the phone while it was in this state. I restarted the phone by holding the power button and volume up at the same time. The phone restarted but the screen remained black ; the screen did not light up at all. The phone was in fact powered on and eventually the android "tic...tic...tic" sound played during device boot, when awaiting user input (android tic sounds played while awaiting password input during startup). While the speakers worked the the power led located in the bezel still lit, the screen remained OFF/dark. While continuing to hold the phone and move it around the screen finally lit. The left side of the screen appears "stuck" (does not refresh). Whatever was displayed on the screen when this condition occurs remains frozen on the left side of the phone. It's a perfect 50/50 split. In other words, the left 50% of the screen (portrait orientation) has a complete image "stuck" on the screen from whatever was displayed when the screen last froze (eventually it releases and then immediately freezes again). The frozen left side of the screen eventually updates as you continue to interact with the phone (this is NOT anything like burn-in). It's lit nice and bright but the left side of the screen appears to freeze and will not refresh while you interact with the device. The right side of the screen continues to update normally. I was able to capture a screenshot (power button + volume down) and confirmed the image captured does NOT reflect the display issue. This appears to be a hardware failure. Other Razer phone owners are reporting it and a video has been posted to YT demonstrating the "Razer phone screen problem?". Razer has offered an RMA however they DON'T afford advance RMA (you must ship your device to them, they receive it, then eventually ship a replacement). That's unacceptable for a $700 phone that took over a week to arrive because they shipped it from HK and got stuck in customs. Buyers beware, I would avoid this phone for now until the cause of this issue is identified OR Razer strengthens their replacement processes..
update/more info: I was able to complete a factory reset and the issue persists.
also, as another user stated above, pressing lightly and applying pressure around the edges or to the screen does appear to cause the screen to light back up again when it's dark (in other words the screen goes to black and will not wake. then when you apply some light pressure around the device it reliably lights the screen again; until the next failure which is moments later)
Hi my razer did up date swiched off and has never come back on dont even show charging has eny one els had this
I've got my Razer phone on the 20th of December 2017. Used it a couple of months before noticing the entire top part of the screen having dead zone. Rendering my phone to be unable to tap on anything on the dead zone. I've proceeded to exchange emails with Razer and got it RMA-ed on the 20th of March 2018. To my surprise. My 2nd set is experiencing the same exact issue right now in less than a month of using it. Are there anyone else out there experiencing this issue?
Got my razer phone on the 20th December, last month while using Google maps the left side froze for a bit, fixed it at the time with a reboot, didn't do it again till last week and now does it all the time. I'm waiting for an RMA guy from razer to email me back, and I've put a post on Reddit under the /r/razerphone sub to keep everyone interested how my RMA process is going to go. How long does it take to get your fixed/replacement phone back to you? If I dropped the phone and broke the screen, my insurance company would replace it and get it back to me within 5 days for £25 fee. I bet razer are gonna take weeks.... ?
razer screen problem
since i got the phone at the start the screen was flashing black then an hour later phone was all gucci,now if i press the side of the speaker like a small bit harder the whole screen goes black untill i manage to restart the phone, now at all i dunno whats happening nothing happens all i does it vibrates when i try to unlock the phone theres no sound anymore when the phone gets unlocked so im guessing i cant restart it anymore cause it dosent unlock :/
if you need any pictures / videos
Dm me on IG: Pekiuks_YT
discord : Pekiuks#7734
ok thanks , i should refund it or no because i need to factory reset it but i cant see anything cause the screen is black .

Bought Razer in March. And now have same problem !
Hey there. I'm a bit new to this side of XDA. Honestly with how long I've been AWOL from this site nothing is familiar anymore. How time flies. Well my first post back in years couldnt be more unfortunate phone wise, I've had my Z2 for a couple of months now and as a mechanic it's been treated like all my others phones prior, rough. I've been locally recognized as the guy who has a new phone every couple of months because he can't not shatter a phone. An expensive hobby of breaking phones. Well luckily I didn't shatter my Z2. I just water logged it. Gotta change things up right? So here's where the interesting problem comes in, I let the phone sit in rice for 30 hours, switching the rice out half way through. It acted up like you would expect in the first couple of hours but then stopped. When I pulled the phone out I scraped the rice out of all the books and crannies and tried to power it on, to no avail. Dead battery I assume, so I plug it in. Charge icon pops up, a sign of life! How glorious. So I let it sit for a minute as I assume the battery probably dropped below minimum voltage when the LEDs were freaking out. Went back to the phone, held the power button and no screen, but "Hello, Moto!" So at this point I'm convinced the screen is dead, so I force it off with the volume down method and pry off the screen. To find what? More water. Good Lord. This phone is incredibly water resistant just in reverse. So I do the only thing that makes sense at this point, I remove the ribbion connector from the board for the display and put the phone back in new rice as 2 separate pieces. I then leave it in there for another 30 hours switching the rice halfway. Bringing us to now. I took the phone out, cleaned all the rice out of the 2 pieces and off the remaining adhesive and connected the ribbion back to the board. Plug the charger in, and again, charging logo. But then I hold the power button and the TMobile splash screen pops up! Then the screen goes dead and once again, "Hello, Moto!". But whats different is now when the boot sequence is finished I can interact with the phone and it works, shake for flashlight, enter my passcode (just by feel cause I'm good like that, ladies hmu), and the button responds with vibration. The phone is working but no screen. So at this point I'm sure, the display driver is done. I murdered it in cold daylight. So I shut it off and start looking around for new screens, in the midst of this I knock the phone and accidentally hit the power button, and it starts to boot up. T-Mobile spash screen, screen death, "Hello, Moto!", and nothing. Now that seems weird. Why would it work twice on the TMobile splash? So I decide I'll try putting it in fastboot for S&G's. Restart, put it in fastboot and the screen stays on. Beautiful and clear as day, all buttons work, everything reads fine, but, if I go to boot it or do anyother action than "retart bootloader", the cycle continues. T-Mobile, death, hello Moto, nothingness. Now at this point I'm okay with the phone being dead, it's fine, but I'm intrigued now. What would cause the screen to work just fine when in the bootloader and the TMobile splash screen, but die when it boots? The phone is very clearly working in the background. I logged in, used Google assistant, used the flashlight, pressed buttons on the dialer, all without the screen but with haptic feedback and audio. Could the graphical side of the main partition just be corrupt, or maybe the display driver is dead but the main board interacts with it differently during fastboot? I'm far from being knowledgeable on the hardware side of these things but I'm really genuinely interested in getting feedback here from anyone with an idea of what is going on. I'll post a video here in a half an hour or so when I finish up with dinner.

Well... It sounds like there is a short between the screen and the main board. It could have happened when you plugged it into power while parts were still wet causing a short to ground and frying a chip that controls display but not touch on the screen.
Best way I can describe it for you is if an ECU on a car got wet and shorted out. Everything works but you get an engine code for TPS sensor failure due to said short. (The ECU can't read TPS due to a short). That is what seems like what happened.

Well see I would think that as well but the screen does work. Just only in fastboot, and the boot logo.
I got the video here.
Fastboot is a pretty low level and most likely uses basic hardware. I mean really what is there to see but a simple background with some text. Once you load the OS then all the hardware and it's drivers into play. Have you tried booting into safemode? Ultimately you'll probably have to repair or replace, but there could be a slim chance that there's still a little moisture in there and it still has a short somewhere.
