yeah its a first time question for me and I'm sorry if it has been covered, I did try to find it. So i replacdd a display on the the deivce and it will not power on or give any sign of life. I checked with my meter and its got roughly 3.5 volts which is good enough to power. any one have an experience with this and know the correct method of getting it to power on? tried volume down and power for ten seconds didnt work. I've got it on the oem charger now even though it has a charge.
Wrong forum... But maybe your digitizer isn't plugged in correctly? Our the digitizer was crack in the process of replacing it

Yea, I have replaced several on the xt910/912 may be an issue with the install check the ribbons for tears... ensure that there both seated correctly.. replace the metal cover over the connectors... did you replace the full housing or just the digitizer/ screen? Or Item may be defective... when plugged in you should still see the led flash green if all is well with the battery ( the ones I have done did)...

re: answers
yes, i should have seen some sign of life is what i was thinking as well. i replaced the whole bezel. no flash no green light and no idea. I do apologize for wrong forumn.only thing i can think of is that when taking the motherboard off the back of the display is maybe something above got damaged. i thank you both for your answers. is there a heat rip sensor on this model that would cause it to go into protected mode even though it was totally disassembled? i had used my separater to warm the adhesive to make removal of the baord easier
I'm unsure about the sensor... but I use a heat gun as well and never had issues with the Motorola's... i have 3 here one still on GB and the other two on jb.. if you know of a way to get me a shipping label I could send ya one if you think its the logic board or battery (screens are broken)...

Very appreciative man, but the riddle has solved itself. I have changed charging voltages every few hours from different usb sources to wall and to computer. it finally flashed n and i got life. I had a very distraught customer.(not to mention the guy who said sure gimme an hour) xda is a common answer to my google queries.I'm glad that i did finally join. :good:

Hi all... I have a vibrant w/ a broken lcd/digitizer. This means that the screen won't turn on whatsoever. How can I tell if that is the only thing wrong with it? In other words, how do I know that if I fix that, it will work again? Is there anyway to check circuit board current or something to see if its working?
I was wondering if the operating system should still be working even if the LCD/digitizer is not working... I ask this because I tried to put it in download mode and hook it up to ODIN, but ODIN didn't recognize it. This leads me to think that there may be another problem too and maybe I shouldn't waste my time. Thanks!
If usb debugging is enabled, turn the phone on and do adb logcat.. Should show the bootup process.

Try and turn the phone on normally, plug it into the pc and see if anything appears in device manager.. if not, no good.
The phone should boot up normally without LCD. It should play sound. The buttons should light up. It should ring with simcard inside. It should charge battery.
Put motherboard inside different vibrant.

My vibrant's lcd/digitizer just broke today.
What is the cheapest fix?
Is it possible to successfully harvest a working screen from a different phone or would the screen most break in the process?
It is possible but have to use a lot of heat and do it very slowly

A 1500W hair dryer on high will do it. Heat it for 6 to 10 minutes moving around the edges. When you remove it do it from the top first and don't separate completely at the bottom until you remove the soft button ribbon. It's fragile and will break if rushed.
Unfortunately I think the whole phone is gone... My computer doesn't recognize it, and i get nothing when trying to turn it on... Completely dead. I bought it used to try and fix... Oh well. Guess the motherboard is bad too. :-(
sorry to hear that, at least you double verified iit is fackled though.
Maybe it's battery? Dead battery might not turn the phone on eventhough you have charger plugged
So would it be possible to put a good motherboard into another bricked vibrant?

Hi
I got my HTC one just under a week ago on three and I'm in love with it. But there are some things I'm worried about. One thing is that when I play games or plug the phone in charge the cool aluminum back becomes rather uncomfortably hot and makes me have to switch hands, it doesn't burn but it does irritate...
Secondly I've seen some posts about gaps at the top and I have those but I was wondering if anyone else has a very fine bulge of the plastic above where the usb port is? I don't know if this is a fault of my phone or it is a general thing so I don't know whether to ask for an exchange or not... If anyone wants pictures of the gap just say!

The tiny white bit in the right side, look across the phone and you'll see it better because you can't see the white bit anywhere else... I do have really sharp eyes though so If you can't see it I'm sorry

I can see it, i have excactly the same on my One, im just living with it though as everything else is soo perfect!
The only thing im worried about, is were that is, were the charger plugs in, the 2 little 'Catches' on the charger that hold it in rub on the white bit, in other words the hole seems to small, only slightly, i may contact HTC about this as im a little worried it will cause future problems like a Broken Charger or Charge Point etc. . .
Yeah that's exactly what I was worried about with the charger thing, if you do contact HTC let me know how it goes

Mine gets very hot too, I'm guessing that is a metal thing though, the gaps don't bother me or any slight overhang.
For me the issues are...
Blinkfeed
Heat
slow charging
home button is so hard to hit because it's small and in the corner
no battery percentage
no file search on the phone

Try a launcher or put blink feed to the side and disable all sources? The file search apps on the market do me fine but normally they put something on the battery so there is less heat transfer to one spot I n the metal but I don't think they've done that in the first batch :/ and mine charges pretty fine as well

I too have the overhang on the charging port. I have had two handsets (first one replaced due to gaps at top which moved when pressed) and its been on them both.
Second one has a slight dent/scratch in the white band, so ill wait another week (still in 28 days) and try and get another swap out. I do love the phone, battery life is immense, I'm getting about 2.5 days out of it at mo.
I have owned so many HTC phones it boggles the mind. In that time I have had to have 3 go in for repair. On stopped charging (one S) another had the wifi GPS glitch (one X international) and one just plain died one day to never turn on again (ATT one x+). All of these were taken care of by HTC. Can't say without issue, the international one X they scratched the case and took a little while to get a new one but in the end all my issues were taken care of. I would really say wait until HTC has resolved these issues and then they will take care of you 100%. You will need to be able to send the phone in for repair but they are fairly quick about 10 days total turn around time. They also didn't have any issue at all repairing a international phone at the USA HTC repair center something that is not true with Samsung.
Are you in the UK or America? Cus if you're in the UK I think I can get an exchange as well

Hello, today I dropped my nexus seven from very low and when I picked it up it wouldn't turn on so what I did is went and charged it and the backlight turned on but no charging image or anything whatsoever was appearing so then I tried holding the power button and it just made it go all crackily like a TV the Nexus has no cracks on the screen but just won't turn on, please help if you know how I could fix this please let me know
Try taking off the back cover, more then likely its your battery cable is loose. Happened to me once before
Sent from my Nexus 7 using xda app-developers app
Thanks mate that fixed it all I had to do was pry open back and then push down the connector and then babam it was fixed
Turns out it didn't work
So I opened back and pushed it in (It was already in very tight) and then I put case back on and nothing if I go to charge it it just puts on the backlight or flashes :/
Never had it persist like that. Try taking the ribbon off the connector a few minuets, while doing so check the male and female connections and see if nothing is bent/broken, if all looks fine plug it back in.
Off all fails, it might be the display ribbon loose, but I can't really tell you where it is or even if its a good idea to try to mess with it. Look up some videos on YouTube and see if the job would be easy for you. If not, you might have to send it out to get fixed. Idk what they do with rooted ones, maybe someone can shed some light on that topic.

I had some rain droplets get into my phone which got it wet on the inside of course.. I did the whole rice thing, took it apart, bathed the motherboard in isopropyl alcohol.. basically for about three weeks I let it dry and cleaned it..
Last night I put it back together, connected to power, and let it sit. Turn it on this morning, it gives the vibe, system boots up, makes the proper sounds, responds to touch (I feel the haptic feedback when unlocking the phone).. BUT.. the screen doesn't turn on at all. I did some testing like trying to enter the wrong unlock code and cerberus did take and email a photo to me, so it seems like everything else works. Connecting it to the PC shows all my files as it should.
Question: could the battery be damaged so that it does not have the power to turn on the display but can turn on the rest of the phone's functions? Or did I somehow screw up the display connector? Does anyone know the inner workings of the phone that can help? Are there any diagnostic tools I can run having the phone connected to my PC that would show me if there's something not connected or fried?
Oh, also, if I restart the phone by holding the power button, the LED blinks red a few times.
Maybe the screen cannot access the power due to a wet or damaged component making it partially not working correctly like the screen cannot display what the main board is outputting.

Hmm could be.. not wet though.. the phone was disassembled for at least 3 weeks on my desk...only thing i saw that could have been damaged was the sim card connector though, and i cleaned it up a bit with alcohol.. the display connector and everything in its vicinity looked good

Try to look really carefully for any damage, maybe there is some damage which you cannot see at all.

It is most likely the power supply built-in to the Nexus 4 which had a malfunction due to the water causing one part of the connector not to pass power to the screen BUT it allows the rest to do so the only thing you need to replace is the power supply inside.

First thing to check is to pop the back off and make sure your battery is fully plugged-in and seated firmly.

Remove the cover from the back of the device, and make sure the battery is plugged in firmly. A loose connection can cause these symptoms (this happened to me in the past).
This guide will show you how to remove the back cover, and has nice pics of the battery plug. https://www.ifixit.com/Guide/Nexus+7+Battery+Replacement/9895
You don't actually need a specific tool, you can just use your fingernails (if they are long enough) or any small, thin object to help pry it open. It's easy, just take your time and don't force it, don't want to break anything

Did you make any changes to the device before this happened (new ROM, kernel, etc.)?
If not it's likely a hardware issue.

Sent from my Nexus 7 using XDA Free mobile app
Well, that might be why it was sold on ebay in the first place, or it may have been damaged in shipping. You should check out swappa.com for used tablets next time, I've had great experiences with sellers there.
You can always try a factory reset, or using a battery calibration app, or installing a custom ROM/kernel, and see if there's any changes.
It also may just need a new battery, though that involves spending more money just to test the theory. It may be worth a shot though.
That's all I've got, if none of the above resolves the issue, it's likely just a defect with the device.
Good luck.
