I dropped my HOX and I got another HOX with working mainboard. I replaced it and everything worked except for very faint backlight and flickering. So I disassembled the phone and put it back together again. Now I can't start the phone anymore and the solid red led burns when connected to the charger....after I connect it it flickers one time, very fast. Does anyone have an idea what it could be? So pissed of right now...
Hi, if you don't have any power at all eg no vibration or lights on three bottons at the bottom, it could be that the power connecter is not properly plugged in. follow cabble down from power button, plug is hard to get at unless you unstick power button from cassie.
If you have some power check lcd is working by using a bright light near the screen and closely checking to see if you can see anything, could be backlight not working.
just my 2cents
feel bad for ya!

The cable is connected and I'm afraid the display shows nothing Thanks for your reply.
This might work

Okay, I have experienced the same thing and I'll tell you what I did to fix it. I dropped my HOX after owning for only a few days and the screen was cracked. I ordered a replacement LCD/ screen digitizer part and took it apart. One of the things that I found was that there was adhesive everywhere, including adhesive on the connection to the battery.
After it was taken apart, I attempted to test the new screen. It was then the LED turned solid red and the phone would not power on (even after 10 minutes of charging). What I did was remove the adhesive from he battery connector and disconnected the battery completely. I plugged it back in 10 seconds later and it turned back to flashing green (which is normal because I had several missed texts).
So my solution was just to unplug the battery and it worked just fine. The hardest part about this whole process was putting the cover back on, especially on the side with volume buttons! Hope that helps.
I have exactly the same problem. The difference is that now that I took it off charge, the red light is flickering on and off. I cannot get the display to show! Please please help.

Hey there guys,
I was repairing an HTC One X for someone i know, (she dropped it and broke her glass) but since i got it (ofc) i tried to turn it on.
No succes. So hey, why not walk to the charger and plug it in? No charging light.
Opened up the phone and checked all the connectors. they were fine.
During an hour or two charging, i was googling, and some people reported that holding vol +&- and power button would revive it. no success.
I'm not replacing her glass untill i know this isnt a hardware problem
Please, share your knowledge
Greetings,

UPDATE: Suddenly the hox's led started to blink, idk anymore what i tried and buttons and power combinations but lets leave it going. fingers crossed then.
UPDATE: No boot after the blinks (just faded away again), put another battery in it and boom, it booted. only nothing on-screen lol, lets replace that screen.
I found this phone in a parking space with an otter box case on it. Now it was probably ran over because the LCD is cracked and doesn't turn on (no hdmi-out to test that) but I was thinking I could fix it. When I plug it in, it just vibrates at even intervals and doesn't shut off. When I try to enter into recovery it stops vibrating as long as I'm holding the buttons, and then starts again as soon as I remove my grip. After waiting a bit, a blue LED showed up for a minute or so and the two bottom buttons lit up. Right now I have it charging, and when I click the power button those lights go on temporarily. Pressing the volume buttons, they make noise and light up.
It seems like it works, but is it worth fixing? Is there anything I should do to troubleshoot it? What is the vibration?
This is a new battery I bought online.
Regards,
Myles

It probably wouldn't be worth fixing, most people report their phones lost or stolen when things like this occur, which in turn gets the imei black listed. You could check on www.swappa.com if it has been yet, and it could be black listed in the future which would cause the phone to become unusable on any network/provider.
Sent from my SAMSUNG-SGH-I747 running S3Rx MJ2 bootloader MJB modem and it is smooth
I replaced my HTC One X screen because it's cracked. I am pretty sure I did everything correctly.
I followed this video:
https://www.youtube.com/watch?v=f3wxy4wUlRw&list=PLv54VHJgYuodvmY7ySEUEjOZcbptZtmG7&index=4
I tested the new screen out mid-way, like the video, and it worked fine (I'm using the SHARP variant, as it was identical to the cracked one).
I then placed the screen into the housing, and connected everything back up. Put the screws back in, but before putting the back cover on, I tried testing the screen. It wouldn't turn on. The capacitative buttons light up on reboot, but the screen does not. When plugging it in, the notification LED lights up a constant orange, and it comes up on my computer.
I've read some people having this problem, but I'm not sure what to do.
I took the screen out, and put the old one in (the cracked), and it too no longer lit up! Same problem as the new screen. So how do I fix this? The Flex cable is 100% in the jawbone connector, so it's not that. I don't think it's a short circuit, although it is a possibility.
I spent $90 on this, so it's quite disappointing if it's all gone to waste.
UPDATE:
I found out that the screen is working, it's just extremely, extremely dim. It's so dim that I needed complete darkness in my room in order to see the screen. I only glimpsed this once, and I haven't yet been able to get it to turn on again.
What's strange is that the screen doesn't even light up when powering on, there's no HTC boot animation or anything. Is this a hardware, or software issue?
I'm going to fully charge it, and take the battery out for 3-4 hours, and see if it fixes it.
I think it might be a shorted 220 coil, that's the only explanation I can think of to cause both screens to not light up.
Does anyone have any experience replacing the 220 coil? As I'm not sure how to remove the 220 coil. Do I just pry it off?
So here's how it went:
I opened the phone, replaced the port (the small boardlike thing)
assembled my phone to try it.
The phone started
Then I put all the screws and sim card But I didnt get signal no matter how long I waited
So I dissassembled it again. I was a bit harsh and broke the "Power" button. (the rubber thing that makes it bounce fell off, and an small metallic circle that probably completes the circuit fell off as well.
(Google "galaxy note 2 charger port" for a picture, cant post external links @[email protected])
Checked everything was plugged properly and tried to start it with the tip of a paper clip to complete the circuit where the power button should be (that small round thing)
Nothing happened so I googled a method to start it without using the powerbutton:
youtube: Gre9qaJyCZw
Basically its to plug the charger, wait for the battery logo to show, unplug, take out the battery and put it back in quickly.
So I assembled the phone again to try that and when I connect it to charge it the screen flashes for half a second (no words no nothing, it just brightens up for a bit) And then the red led that means its charging turns on after a couple of seconds.
After doing the trick, the led turns on blue....then the phone vibrates a bit(seems its starting up, but with no sound or nothing in the screen)
And then the "menu" soft key blinks a couple of times and then back to nothing
So I just have no idea what to do @[email protected] I dont mind replacing the button but I would rather not spend on it if there's something else wrong with the phone...any ideas?
And I just bought this to replace another phone that broke ;_;
EDIT::::::
I replaced the charger port for the old one and tried the starting trick. but to the same result: after doing the trick, the led turns on blue....then the phone vibrates a bit(seems its starting up, but with no sound or nothing in the screen)

you probably messed up the mainboard or some connections.
Try to power it on with microusb board disconnected.
Make sure every single connection to the main board is connected properly

Any suggestion as to how I can start the phone with the power button broken and without the microusb board?
I already checked all the connections that you can see when replacing the microusb board (the back side of the motherboard) Is there connections worth checking in the front?
Do those symptoms sound familiar for any specific problems? (Like non working screen or motherboard)
- Charging takes a couple of seconds to turn on the red led when connected but shows nothing on the screen.
- Trying to start it with taking out the battery trick makes the led turn blue, then the phone vibrates a bit, then the menu soft key flashes a couple of times.
Update: I found 2 more symptoms
1° Kept restarting the phone with the battery trick, and a couple of times I could hear the music of the phone starting up, but it seems to be at random or due to some factor I have not spotted yet
2° If I connect it to the computer it detects the phone and lets me access the files. Kies detects it as well
If phone can be accessed through kies I think you have broken some connection between logic board.
Power button and volume + - buttons should have the same round metal part, which will work after swapping.
I think you should give up, maybe there is still hope for repair.

Thats the weird thing. if you take a look at that phone's board, the only things that are within "breakable" range when you open it with a plastic tool are:
power button
charger port
earphones port
volume buttons
And they all seem fine except for the power button. there's no other flexors or anything even remotely close to where the tool was used. (and where I got a bit rough)
So I was using my tablet one evening and the battery was drained down to 5%. I turned it off and set it away. When I returned to use it the next day it wouldn't turn on. Thinking it had no charge left, I set it to charge. I noticed the red charging light would not come on. The screen remains black at all times. I could feel a source of heat from behind the plastic backing. Some searches indicated the charging cable from the battery to the motherboard could be the culprit. I opened the back and found it seated. I removed it and reseated anyway. I left the cover off the back and plugged in the charging cable. I could feel one of the chips by the power button getting quite hot. Again, no red light to indicate charging, black screen. I have tried plugging the tablet into my computer and doing every combination of button holding for minutes that searches have supplied, POWER+VOLUME UP+ HOME, POWER+VOLUME DOWN, etc. No luck. I purchased a newer battery ( I've only used the tablet for about a month, and sparingly at that) and swapped it. No red light, same hot chip. Is the motherboard junked? Am I missing something? Appreciate any help.

So,
Rodserling, What happened?
Metako-a-o-yasin.

Scritterz: Nothing has happened as of yet, it's become a paperweight.
Thanks Mr niceguy, I'm going to give that a shot. Couldn't hurt. I have however already purchased and installed a new battery with no change in operation, that chip on the motherboard still gets hot, no charging indicator light is lit and it just sits there not turning on.
