HELP> Flashed Desire Rom, now screen wont light up

I have a serious problem. I noticed a bug in the Desire alphas where sometimes when the backlight went off during a call it would not come back on when the i took the phone away from my face. It always came back on eventually.
Ok now yesterday I flash alpha 8 and it worked fine. Now all of a sudden I reboot my phone bc the battery dies and the backlight won't come on at all! I know the phone is on because the haptic feedback and cap buttons are on and if I leave it on I can tell it's getting notifications.
How am I supposed to fix this?! I can't even see anything to get into recovery! My phone is unusable.

Find out every step to do a backup in recovery... see if that works

Load into bootloader
Press power button once and wait about 20 seconds
press volume down once then hit power button once
Wait about a minute and move the trackball down slowly 3 time and press it
Scroll it down once and press it four times

Unless your screen is broken you can always boot into recovery.
Take out the battery, then put it back in.
Hold the trackball down as you power on, this will boot you into fast boot.
Select bootloader, then select recovery. and bam your in recovery and can reflash.

I can get my phone into recovery. When I adb in i can push the phone into recovery, then when i hit adb devices it shows my phone and says recovery.
the problem is the backlight is not on even when i am in recovery. i would say the screen broke, but it seemed like a software problem, because it was just slow to come back on. It still always came back on. then I left it in my car chargine and it never came on again. The phone seems to be working fine though.

Kind of off topic, but did your call screen do this before flashing to Desire at all? Did you recently install a screen protector? I had problems with the PhantomSkinz screen protector making the proximity sensor less sensitive and behaved exactly how you're describing...as soon as I took it off it started working again. I'm now using a dcmugen88 screen protector and it works great.

interesting. i have one of those bodyglove or whatever protectors. best buy glued it onto my lcd. i suppose it could have started around that time. but would the proximity sensor still be deactivating the lcd even when its booting up or in recovery?

Oh, I must have overlooked that. The screen protector wouldn't cause any issues on startup or in recovery... guess it must be the rom then.

well, figured it out.
warning to n1 users: watch that lcd screen under the glass. its not nearly as sturdy as the glass cover.
the lcd/digitizer screen under my glass got cracked and stopped working. no drop, no warning, no funny colors. htc does not cover this in the warranty no matter how good the actual phones condition is.
i almost didnt get another n1, a phone thats inherantly weak (i found dozens of similar reports over the web) is not exactly a good case for a system with no insurance, no store to walk into, and very unhelpful support. they try to be very nice, but the rep i talked to couldnt even tell me whats covered and not. he just said let us charge 500 bucks to your card and we will ship a replacement, then decide if we think you have to buy it once we get your old phone. i demanded to talk to someone who did know. his manager denied hearing about lcd screen problems... after the original rep said he and htc knew this was a common problem. google didnt even return my email when i first contacted them saying my backlight was broken.
so again, be careful and get a good case.

Unroot G2 with blank screen

Hello all, I have a terrible problem.
The Screen for my G2 went blank today, and I have a feeling the culprit is the cheap exposed ribbon that lies in BETWEEN the keypad and the actual screen, perhaps being punctured by a comb while in my pocket. As a result of this exploit, they need to set up an exchange with a newer model however..I perm rooted and OC'd with a Custom ROM (. Is there ANYWAY possible, for me to un-root the G2 without a visible or interactive screen? My buttons and screen aren't active but phone turns on and charges..
I'm praying so hard this is possible or I might be screwed

Don't worry about it. Just send it in as is. I had the same problem and had sense UI Rom on there. You can even hear the quietly brilliant chime as it boots up. Just the screen is blank. Just don't mention to them that you rooted it. You'll be fine. By the way make sure you write down the tracking number for the return label so you can prove you sent the old phone back in case something has happened to it.

Ha you're so awesome and made the weight lift with ease..was almost scared to death for a second

CM 7.0.3 messed up my phone?

I had cyanogen 7.0.3 (stable) with the theme Dark Ginger since it came out until about 6/17/11 .. I was using the phone texting and web a few minutes before the phone restarted by itself I took it out and saw the HTC screen and put it back in my pocket when I checked the phone back a few minutes later after I unlocked the phone by pressing the track pad the screen was black and I know the phone was on since the command buttons on the front of the phone was on .. So took out battery and reboot about 3/4 of the HTC screen was black and the remaining portion had random white lines running vertically when it got to the second splash it was completely black with a few gray lines and when the phone started up the only thing that was on was the lights on the buttons again .. There is no physical damage on the phone so I know the screen was not cracked and even though the whole screen was black I picked up a call by swiping my fingers across it a few times lol ... Just wanted to share my experience maybe you can't have a rom on your phone more than a month or 2? I guess you have to keep flashing new roms on the phone ... I got a new g2 in the end luckily

that does sound more like physical damage or a manufacturing fault. I would be very very surprised if a rom could do that to a phone

You kidding? The vast majority of smartphone owners stay on the stock ROM, and are on the same ROM for many months, maybe even years, aside from OTAs (and depending on your phone and carrier, the OTAs can be very infrequent).
I agree with above, what you've described sounds more like a hardware issue. Even if the phone was not damaged, things just go bad after a while. And screen failure is a known issue with this phone.

Its probably a manufactured fault .. When I had my g1 I used to flash new roms every other day or week I had it for 2 years without any problems .. the g2 is the first time I actually left the same rom on my phone for an extended period hence the thought that the rom was to blame was a possibilty since it looked like it got a virus or something when it crashed* so suddenly :/

It doesn't seem like something a ROM would do to your phone.. probably faulty connections to the screen or something..

I've had a nokia and a motorolla do that, one was dead the other was the connector. If it's under warranty, which I doubt since you've flashed it, send it back otherwise open it up and check the ribbon connector to the lcd screen isn't loose (based on how I fixed my moto). Failing that you could probably get a replacement screen off ebay (based on my nokia).

Thanks for all the responses I actually got an exchange for another g2 .. I appreciate all the hard work the devs put into their roms and the time they spent on them I just posted this topic to maybe solve the problem incase someone else is faced with it .. since I don't have the phone anymore I can't verify if it was the screen or some other mechanical problem

Can this G2 be saved?

My phone seems to be working fine, but it is hard to tell since the screen usually won't turn on. I say usually because once or twice a day I can wake the phone up and the screen will work, but as soon as the screen turns off again it usually won't come back on.
I am wondering if I wipe the phone back to stock if that might make it work like normal again, but my question to you is, Can I restore the phone to its original state without using the screen? Every time I try to boot to recovery or bootloader the screen stops working and I am stuck. Can I use ADB to do everything? If so, I need to know the commands to type in.

Is your ribbon cable loose?

I followed a PDF a member called strawmetal made, didn't need the screen, returned it to stock and sent it in

My phone also has a problem that sometimes appears.
Sometimes, the screen won't turn on at all. I would use the phone normally and lock the screen. Then, all of the sudden, when I pick it up again it wouldn't turn on at all, it's like it shut down.. After pressing the POWER button, it reboots and then works.

I am still thinking this is a software glitch rather than a hardware problem. The screen came on the first try this morning and I went into Our Groceries to add something. When I backed out of it the screen turned off, and hasn't come on since. Also, last night it was also working and I went into settings to lower the screen brightness. No matter what I set it to it stayed the same, and the Auto setting was unchecked. I think I need to just reflash the rom but I don't know how to do that without the screen being on.

Some phones have problems handling low voltages in sleep mode if you have underclocked it. On one of my g2's i had to 384mhz or something like that for the screen to turn on.
I think it was the underclocking, not shure. But something with the screen voltage
sent from phone

If all else fails, flash it to a stock rom. Try to make sure all the overclocking features are turned off. Try finding a rom that's just a clean and rooted stock rom. Do that first, then if that doesn't work then flash to stock.
Remember overclocking isn't for every chip on every phone. Not all chips are made equal, and some can be amazing at overclocking or under volting and some not at all.

That is what I am wanting to do, but how do I do that without being able to see the screen? Every time I boot into recovery, or even bootloader, I have no screen to see what I am doing.

If you can't see the screen even in recovery then it must be hardware. You might have damaged the flex cable to the LCD+digitizer. You can try to flash it to stock with HTC's tools. I remember doing it to my phone without needing to touch it at all. So long as the phone is on and charged, you should be able to do it. Just do a quick search on the forums, but make sure not to flash a rom that you can't root.
You can get it on Ebay for $26. They sell them with tools for a bit more if you don't have the tools.

Wow. So the cable is actually user replaceable? I guess I need a YouTube video or something to show how it's done. Of course, my screen works SOME of the time, so I don't know if I have the guts to perform this type of surgery without a viable backup plan if something goes wrong. This looks like something I would try after I have a suitable replacement phone already. Still, I find it impressive that this part is so easy to find! Thanks for the links!

If you decide to replace the ribbon, go ahead and replace the hinge spring as well, worked wonders for my G2.

i replaced the screen ribbon and the spring at the same time.
it wasn't too hard. takes about 15 - 20 minutes to do it the first time.
you can buy the entire ribbon assembly for pretty cheap. just be VERY careful with the USB/SD card ribbons on the side of the main board. one is a clip, the other is a pull tab. if u dont know which one is which- the phone will not have SD card capability when you break them :-(

This is the dirty secret of smart phones, in that nearly everything is replaceable, and usually for cheap.
Damaged the phone physically = housing = $60
damaged screen = lcd + digitizer = $50
Even the speakers are like $3, and I know cause I had to replace mine. The only thing that'll make you want to throw the phone away is if the main board or logic board is damaged. Even then you could probably find a broken phone that at least has a working board for cheap. I actually bought a $15 broken G2 that I plan to repair and give it to my sister as a gift. I have enough spare parts to make it work.
As for changing it, there's plenty of guides on how to replace the digitizer on YouTube. You have to replace the cable to get to the lcd+digitizer, so just follow the video up to that point.

I just wanted to say Thank You to everyone who helped me on this. I bought the ribbon, watched the YouTube video, and now I have a working phone again! $25 sure beats $350 for a new phone, and it was more fun , too.
Now my screen has trouble displaying colors with gradients. It looks like it isn't showing all the colors, so there is a weird muddy area between the dark and lighter portions, sort of like playing an old Sierra computer game from the 80's. Did it revert to only showing 65k colors instead of millions? Still, not a deal breaker in any way. The phone works and i couldn't be happier!

Nexus 6P screen no responsive, is it hardware or software?

Hey guys, so a few months ago I dropped my phone and the screen cracked, and I had a local repair place replace the screen for me. Well, the other day, my screen decided to no longer respond to touch but the phone is working fine besides that. (Oddly, when I first turn the phone off and back on, the screen will respond for a few minutes before no longer working.) I took the phone in the place that repaired the screen (they have a lifetime warranty) and they said that they put a new screen on and it still didn't work, so it wasn't the screen and suggested that it was a software issue. I factory reset my phone, and still have the same issue. A few questions:
1. Are they lying?
2. If not, if it's another piece of hardware, will Google warranty the phone since it's within a year, even though the screen has been replaced?
3. I've searched online to see if anyone else has had this problem, and nothing seems to be related to hardware, is it possible that it's software and if so, how do I fix it?
Thanks!

I would go to dev options and enable pointer location, and see if the information is what it should be.
Could be a grounding issue, the n5x has this issue while charging, the fingerprint required more pressure too.
Backup your ROM and flash Google's image,
Is the screen from a reputable company.

Yes, I currently work for a cellular services company and it's the one that we constantly recommend because we hear good reviews from customers about them.
