I replaced a screen and digitizer on a neighbors HTC Radar with little issue. However, when I try to boot it back up, it doesn't boot. I am able to tell the screen is working because I have been able to do a hard reset (power and vol buttons, with text instructions visible on the screen), but this just vibrates once upon completion and does nothing else.
When holding the power button, I get a single vibrate every 4 seconds. I have read that this is due to the back SIM door being open or not making contact, but I have ensured (as best I can tell) that the contacts are made. What am I missing!?
You can try putting something like a very thin layer of dielectric grease on the contacts, installing the door, and pulling it back off again. If the grease is disturbed then it's likely they're making contact. All I know is the door causing that problem.

So, being clumsy, I left my Streak in my hoodie pocket. Well, we can all see where this would end badly once I bent down to pick something up. I did, dropped my phone and cracked the screen.
I quickly went and bought a replacement glass + lcd display, and replaced the unit. But, upon turning the phone on, I noticed if I hit it a little too hard on one corner, It would restart, and the vibrator motor had ceased to work.
So I figured, hey, I'll just rebuild it again. So I took it apart. Looked through everything, took my time in putting it back together, because maybe everything wasn't fitting snug.
Now, When I turn it on, every thing is on, buttons light up, and the screen is lit up, but it is black. I never even get to the Dell logo. After about a minute the buttons dim, as if in idle. So i believe the phone still works, but maybe the connections on the MoBo is faulty? Any help would be nice, thanks.
check to see if the ribbons are snugged in place.

Well, I just took off the rear cover and reseated all 3 connections, pushed em in as smoothly and far as they would go. But, same thing. Black screen. But the LED is still working...
I'm having the very same problem. This is my second replacement screen and neither displays anything except black screen with backlight on, and the home + settings + back buttons remain lit. I can hear my phone starting up and receiving messages, but I cannot see anything. I've taken the phone apart and put back together five times between two replacement screens.
Does anyone know what ribbon cable might be at fault for this particular issue? The largest ribbon cable was shipped bent across the circuit board on both screens; there is a permanent creese in both ribbon cables, but I'm not certain this is causing the issue.
Any insight or assistance with this issue would be greatly appreciated!
i just recieved my evo 3d today threw ups. and i noticed my power button is hard to press to turn the screen off... anyone else ran into this problem?
The button is built into the battery cover so remove it and place it back on.

make sure your battery door is completely on and snapped in the correct spots.
i have issues where either the power button is way too easy to press or way too hard. hopefully a new case will solve that.
I had a badly dysfunctional power switch with my first 3VO, I have since exchanged it for a new one.
And, no, in my case it was not the battery cover-power switch interface, it was the switch itself. I removed the cover and directly pressed it. Strange thing was, with mine, if I removed and replaced the battery, I could get one or two presses that registered, otherwise nothing -- no wake/sleep, no power off/on.
My wife and I both have Evo 3d's and her power button is way easier to push than mine. I switched the back covers between the phones and the problem followed the cover. I looked at both and the power button on my cover isn't molded correctly where it pushes on the phone. It is shorter so it sits further in the phone and doesn't work quite right. I called HTC and Sprint and there isn't a replacement cover available yet so they are going to switch out the phone.
I had a power button issue, where if I pushed the button, it would come up with the shutdown menu and no option just turn off the screen. Was in the process of going take it back for a replacement and found that when I removed the case to switch the memory card that my one was working as it should. The hardness went away and the option to turn off the screen came back. Strangest thing I seen since it truly seemed like a hardware issue.
i am going to check a few out in store and see if mine is like what you describe. To me its set pretty low and the button doesnt stick out very far.
Mine sticks out pretty far... isn't easy, or hard to press. I guess i got lucky.
Mine is really touchy, when I press it to lock the phone it sometimes goes to the shutdown popup. Sorry this post wasn't more helpful to the op, lol, just sharing.
Hi everyone.
I have an HTC Radar. Before several days, I took off the battery cover. Of course the phone shutdown. When I put it back and pressed the power on the phone made a buzzing note and gave me nothing but a black screen. I tried several times but the result was the same. I google it a little and found instructions about hard reseting the phone

The phone boots in this mode and I chose to make a factory reset hoping that this could bring the phone back. Unfortunately this had no result. The phone makes the same exactly. Seems to start but then nothing happens. I am still able to get in the special menu where I can choose factory reset. And because I bought this phone from another country I am not eligible for warranty in Greece.
Any help to bring back my phone would be appreciated. Thank you very much
The way you describe what happens at switch on is exactly how my phone behaves without the Sim cover on at the back (I think what you are calling the battery cover).
I wonder if somehow one of the connectors isn't functioning on the Sim cover at the bottom of the phone? On my phone there are three simple circuit connectors where a tab on the cover pushes a metal connector against a metal bed. There is also a small plastic micro-switch on the right just below the main casing and this is activated by a small piece of clear plastic stuck into a holder - I would imagine this could dislodge easily.
I would try starting the phone without the SIM in to see if that is interfering with the cover sitting on properly and activating all the connections and the switch and ensure the cover is on very precisely.
If that doesn't work try holding the switches as you switch on - may need several people for that.
Good luck!
Thank you for your reply. Unfortunately I have tried this solution and nothing happens. Must be sth else. I don't understand why it even starts in the special mode. thank you anyway and I wish you and everyone a happy new year.
1:- hold both volume buttons & press+hold power button.
2:-then u willl go to special menu.
3:-use down volume key to highlight "factory reset".
4:-use "Power" button to select......!
Enjoy.....!
I bought my Prime a week ago and the only problem I've had with it was that it kept locking up and rebooting. No screen problems at all.
Just now I placed it on my bed and it slid off and fell on the ground which is about a 2 - 2.5 foot drop. After that, it seems like my screen is broken. When I press the power button, nothing happens. If I press where I think my screen lock is at and try to unlock it, I hear the unlocking sound. I also hear a sound when I click where my notification tray is at. Even rebooting(by holding the power button and guessing where the "Ok" button is at) doesn't do anything, I don't even see the boot images.
So it seems like my screen is broken. My question is has this happened to anyone else? Where you able to fix it or did you have to send it in? If you sent it in, did you send it to Asus or return it to where you bought it from?
Try hard reset using the hole on the left of the tablet.
It's on page 3 of the manual.
Had to do a battery pull last night. Had my phone in my pocket for probably an hour, when I pulled it out the screen was black. LED would flash ocassionally and I think I heard a text so everything was fine except the screen. I have Always On off, and I require either fingerprint, a pin, or OK Google voice recognition to unlock.
Tapping the screen, hard pressing or fingerprinting the power button, volume buttons all did nothing. I guess there's a dialog for powering off the device so holding the power button didn't reboot it either. Eventually pulled the battery and it rebooted fine.
Anyone else had this? Pretty disappointed. Haven't installed any new apps in the past few days. I've heard (and had once) a related issue where the phone takes a lot of presses to turn on the screen—in that situation, Always On is on, it's in your pocket so the phone detects and turns off Always On, and for some reason when you pull it out it very infrequently takes a little while to come on. No idea if they're related.
Do you have a screen protector, skin or case installed? Maybe it's causing issues with the sensors in combination with something else?

This just happened to me yesterday. Dropped the phone, and it stayed on but the screen is completely black. I opened it up and tried re-setting the display ribbon cable, but that didn't do anything. Anyone have any ideas what the problem might be?
