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

Backing Mr. Gmaniac up:

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.
okay so sometimes my G2's screen will have spots in the screen where the color and outline of whatever is on the screen on fuzzy blue and red, i would show you but whenever i use shootme to capture my screen it shows up normal. whenever i slide the screen open it gets worse, so ill get lucky when the screen finally goes back to normal sometimes. but i got used to it and now sometimes the screen will flicker and shut off. i cant even get into recovery or the bootloader because of the screen problem. its becoming quite annoying, is there anyway i can replace the screen? or how could i go about getting the top part of the phone replaces as i believe its a problem with the connecting ribbon inbetween the two halves of the phone? bleh
Help would be greatly appriciated

Sounds like the ribbon cable between the screen and the keyboard may be damaged.

yea thats what i was thinking, it seems like the most obvious choice. everytime i google replacemnt screen ribbons all i can find is camera and keyboard ribbons or something. do you know anything? im think my upgrade is soon and G2xs are free so im just gonna get one of those, they any good compared to the G2?
Ok, so i'll start of by saying rougly 6 months ago I bought an unlocked T999V with a flashed ROM which was liquidsmooth 4.3 I believe. The phone worked perfectly fine up until a week ago. The phone was dropped off a desk and landed on its screen, nothing was broken so I thought nothing of it. The night afterwards I noticed a few darkish spots when I would look at the phone at night, only if the background was dark though (setting menu for example). The phone was plugged in when I went to turn it on and it wouldn't. Its unresponsive and I am unable to put it into DL or recovery mode. Leading me to believe its hard bricked and will need a jtag fix. But WHY? Why did dropping my phone all of a sudden mess up my screen as well as brick my phone ? Someone please help me out here :crying::crying:

Are you comfortable opening the device? There's a chance the fall didn't necessarily damage anything, but knocked very important cables loose. I would check every cable connection on the motherboard, and check the battery prongs, as they may not be making good contact causing dead battery. Are you getting absolutely no response from the pc when connected?
Anyway, point is, checking the connections is the easiest thing to do- and you might be able to determine if anything else is loose (ie did it land on the power button and now it's stuck? Etc) It's likely something simple- so check that first, then you can move on to other diagnostics.
The Fall damaged Digitizer. Hence the dark spots. As to unresponsiveness, remove battery and then try. If it still does not work then Power button might be stuck or has loose wires.
I don't know I thought dark spots in a dark room on a dark background were norm for this type of screen- I have them too on a brand new led assembly. Google suggests that's normal and not necessarily damage, although it could be if they're appearing under normal lighting conditions. I agree with everything else though
Wonder if s/he got it worked out?

I brought it into a repair shop and was told the EMMC(?) chip was most likely bad and the phone needed a reflow. I put it in my oven and tried the reflow but no luck, I ended up buying a new T999 as I was quite happy with my first one.
Glad you now have a working device
ok so... the store broke my lcd while they were trying to remove the digitizer... and now i am looking at ebay on which lcd+touch assemlby to buy and i have a question. are the sony, acer and sharp lcd versions compatible with all one x mobos? i did some research and found that the sony version is the best (so they say)

Hi,
The Sony and Sharp are not compatible with each other( I've tried to replace one with the other), I've never come across the Acer LCD in Australia so I'm not sure. If you don't know how to tell the Sharp and Sony apart, the Sharp has Green backing on the flex cable, while the Sony is sort of orange with a few yellowish stripeson the back of the LCD flex cable. Sorry I couldn't find any of my photos which show the difference. I would recommend buying the LCD/digitizer combo and a separate midframe to mount it on, as it comes with new 3M adhesive, but you may also have to add a few TINY drops of instant adhesive, I say tiny as too much will press out under the digitizer and will show up, but I have found that without it the digitizer will lift from the frame eventually due to the tight fit of the frame in the rear shell of the HOX.
Hope you go ok!

Sorry, just a bit of additional info, have also come across posts saying the colours of the LCD look washed out with the wrong LCD.

That's the only downside - having to pull phone apart to check which one you have. Also another tip, phone need to be on to change LCD's, boot phone up with it apart, then wake up with power button on old screen, then sleep with power button, change screens then wake up again. There are plenty of vids on youtube to help, if new screen doesn't activate, check flex cable is in square and all the way - have had this problem before also.

I replaced my screen, but I powered down when removing the screen, and putting the replacement in. Now neither will light up. How do you solve this?
There are no guarantees with this, but try pulling the battery out for a minute or two. then with the original screen in, boot up and let it get to the lock screen wait for the screen to sleep then press power button to wake up then again to sleep. when the screen is sleeping try changing over the screens and then press power button to wake again. this is assuming that the screen displays on startup, but even if it doesn't try this process anyway. if it doesn't work, try doing with the new screen back to the old screen after pulling the battery. I have only ever come across this once, but it wasn't from powering down during a screen change, but pulling the battery seemed to fix it.

I tried that, didn't work. I think I know the problem now. after searching on multiple forums, I think it's the 220 coil. A lot of people have had a similar issue, and they say they've solved it by replacing the coil. What I want to know is, how I managed to short the coil in the span of a few minutes, despite having used the same screen as the cracked one.
It is possible to do, although they can go for no reason, I recommend taking it somewhere to get coil replaced, it is a very fiddly job and you need to have a steady hand and the right tools (hot air gun) although my father managed to do one with a standard soldering iron, although it wasn't the best job. you risk damaging other components also if they blow off the mainboard (if you can find them), worst case scenario is the display ic has gone - that one will have to be done by a professional.
what a sh!t phone
we tried to repare it 2 years ago.
but failed.
so i just the pieces to gether wanted to see if i can fix it.
still not lcd just touchscreen (and now im not sure if i even have touchscreen lol maybe i broke that to now not sure
anyway sucks i have a brand new lcd touchscreen with frame we bought back then. and its even the right screen a green flex cable like the original one and still noting so i guess i broke the 220 chip thing how dont know. but not sure if i can replace it sucks it was a good phone
is there any help a easy fix? or do i really need to soldern that chip i cant sell the phone since there is personal data on it contacts and pictures (i guess dont remembrer)
It may still be replaceable, if it's been sitting for 2 headed is the phone taking a charge? It needs to be on to change the screen. If it is charging and booting up, and the screen still won't work when being changed try doing a hard reset by holding the power and volume down button until it restarts - have had advice by someone who repairs phones for a living that this should reset what the phone is looking at for hardware and you should be able to do screen replacement. Failing that chances are it's going to be dead. Not much point in selling it these days as they aren't worth much these days. If the phone won't start the battery may be dead flat. The phone needs some voltage to run its charging firmware, you can try to get it charging by leaving on charge for 10 min or more, even if no charge light, then hold power/vol up/vol down at the same time to recalibrate the charge circuit, it may start to charge after this.
Let me know how it goes, I wouldn't spend too much time on it, unless it's now a project..

ow volum down? okay will try that. but i think i killed it lol cause the charging light wont come on anymore lol
it was just a idea that poped up in my head, that maybe i can save it so i friend can use it but i think i will just trow it away lol or something will give it a shot and see. will report back
nvm it's dead it wont even boot lol. i think i burned sometime lol that little cable that onder the battery thats conects the botem part with the other fliped out 2 time and 3time it smeled burned lol nvm
Sounds like it may have shorted, a replacement is fairly cheap , just depends on how serious you are about spending money on it.
I forgot to mention that when calibrating charge circuit with power/vol up/vol down all held down at the same time, they need to be held down for at least 2 minutes.

Probably the best result, it's probably cheaper to to buy a second hand one and also cause less aggravation when you can't work out why it won't work. You could always sell the replacement screen.

dont think i will sell it i mean who would buy it? lol but guess i could try for like 20euro or 10 lol.
and have 2 batteries for 10 or 5 euro lol
have 3 backcovers also 2 white and 1 black.
we bought every thing to repaire it but yeah.
could maybe sell some **** but pff dont knopw. (its my oncles old phone will ask him (maybe sell every thing exept de motherboard)
That's what I'd do, try and sell it for parts minus the mainboard. If that doesn't work, put it away somewhere and if you come across a dead one cheap, swap the mainboards out (providing it has the same screen - that's a given). Good luck with whatever you decide to do. :good:
So I tried to replace my pixel 2 xl screen, I had the phone off and was dissassbmling it. I broke the already old broken screen, and accidentally turned the phone on. Since I couldnt use the screen to touch the turn off button, I left it on and swapped the screen out. Now neither the new or old, known working screen displays on my pixel 2 xl. There isnt any obvious damage to any of the connectors in the phone, what can I try to fix this? I was trying to get to fastboot (dev mode is turned on), but I cant see the screen so I cant really do that.
Any ideas? If worse comes to worse I just want to wipe it so I can sell the chassis on. It still works, the alarm went off this morning when it should have!

If your still able to get to the board unclip the screen and battery clean connectors with some rubbing alcohol let dry a few seconds and reconnect the battery the phone should then be off and reconnect the oled panel. before reassembling the phone power on the phone make sure the screen lights up and you have touch activity. Once everything has been tested and working then reassemble. Always test your replacement parts if possible before assembling the device 100%.

I swapped with rubbing alcohol on the end of a cotton tip and tried the steps you said, still no screen activity. Any more ideas?
You said the broken screen doesn't light up anymore? If it at least lights then try to clip that one back in for a test light. I haven't had my pixel apart yet but I like doing phone repair. it is possible that the replacement part is defective? Also try unplugging the screen and battery again plug the screen in 1st and then the battery if there was any copper or silver contact tape covering anything place it back we're it was. Don't power on this time try plugging the phone in and see if it wakes the device!. And also check over all connectors and contacts make sure every thing is clipped in and touching.
