Hi i was replacing LED lights and ear piece of my galaxy S2 and when I finish the only thing that happend was the LED lights came on but the screen didnt not even the galaxy s2 logo I can also feel at the back of the phone it gets hot around when the screen connects to the motherboard and the CPU. The only thing that happend now is the LED comes on some times and i can hear all the normal sounds when the phone boots normally also the phone vibrates.
Any help plz.

You did a nice short circuit in your phone. What leds you changed? Try to clean the flex cable connectors or simply go to the near repair center.

Tmobile UK HD2 with Cracked Dig/LCD, so I took it apart and bought a new lcd/dig. Put phone back together and I have a few problems.
Firstly to get the phone to turn on I have to plug in the mains charger, and then insert the battery. On doing this the phone powers up without me pressing the power button.
Screen light turns on but nothing on the screen. No button lights either.
I know the phone is on as I can use the vol up and down and the sounds are there.
I presume the phone works as the green light flashes to indicate I have a message etc.
Ive re-checked all connections and all are sound.
Only thing I cant check is the LCD itself.
Send the screen back ?
Anyone got an idea what could be wrong ?
anyone help with this as I am without my phone on NAND DAY !!!
Further info: Phone defo working as I can flash Stock Roms to it no prob. Also syncs to my PC. Saw that the black bar than pushes down to hold the LCD ribbon in place has broken, but unsure if this is to secure the ribbon or does it make the connection ?

Hmm, it's possible it helps to make the connection... When you pull it it should secure the cable and at the same time make the connection better.. Try improvising, do something to hold the thing tight there.
Yesterday, my phone fell (not very hard, onto a carpeted floor). I picked it up and put it in my pocket without looking.. When I went to check my phone, it was off. I tried to turn it on, but it would only go to the HTC screen, then the screen would go black but the home icons would be lit up. I took the battery out and let it sit for a couple of hours. Tried to put it back in and the phone wouldn't turn on at all. I put it on the charger, it turned red for about 5 seconds, turned off, then repeats. If I try to turn the phone on, the LED light blinks a very dim red for 2 seconds then stops. I can't even hold the volume button and the power button, it just blinks the dim red. As far as I know, it is not rooted. I got it second hand about a year ago after my phone got stolen. I have never had any problems with it other than the camera.. It just stopped working eventually. Help?
Anytime you drop the phone, even if it wasn't a hard hit, it can damage something on the main board, which could be your problem. However, since you say the led is very dim red, that is a sign that the battery itself is damaged and won't charge. I would try to get a cheap battery off ebay to see if that's the problem.
You probably damaged some micro vital componants on your motherboard which is preventing your device to function in a normal way.
must be motherboard, or some other chip
Hi everyone, this is my first post on XDA.
My S3 had a broken screen, so I wanted to get it fixed. The repair shops quoted quite a hefty price for the repair (even though it was just the glass that was, not the digitiser) so I bought a kit to repair it myself. The repair went smoothly, and I didn't need to do anything to the actual LCD display. However, when the repair was finished, the phone would not turn on. I assumed it had a flat battery (it was on 5% when I started the repair) so I plugged the phone in. The phone's LED lit in an orange colour, that i've never seen before. So I left it for 1 hour, then I came back. The phone still had an orange LED lit. The phone would not turn on. I kept the plug in and took the battery out and the phone vibrated. Then I plugged the phone back in and a red LED lit. I've left it like that for 2 hours, and the phone would still not turn on. I plugged it back into my PC and the LED lit green. The phone would still not turn on but the PC showed "GT-I9300" as a Media Device in the File Explorer but it didn't have anything on it. The phone now displays a green LED whenever I plug it into any normal charger. When I unplug it, the power button makes the phone vibrate when I press it.
Please could you help me? I need a phone.

Red led is charging, green led is charged. Orange led.. Never known it to use orange so i assume its a fault.
It does seem like the phone is booted up and running yet the screen shows nothing. Possibly halted in post?. Have you double checked your work for loose connections etc?. What are the chances of the replacement being faulty?.
I wish I stole my HTC M9.
I didn't actually remove or do anything to the LCD, so it can't be lose connections etc.
I left it overnight on the green LED and it still isn't turning on, plugged in or not.
I'm going to call Samsung to see if they can fix anything or if I need a replacement phone (its about 3 years old so not under warranty though)
It isn't turned on, I tried calling the phone and it went straight to voicemail. And I get no startup sounds, nothing.

Samsung will charge if it's out of warranty.
So what exactly did you do if you didnt disassemble it?
I wish I stole my HTC M9.
Going to send it off to Samsung. I literally removed the screen's glass and placed a new one on.
Can you do that without damaging the digitiser? I would have thought they'd be "married" in some way or other ie glue.

My friend got his new HTC Desire 826 in July 2015. He is having issue with his phone, the screen totally blackouts. He doesn't want to repair the phone because it has no more warranty and will cost much to repair. He asked my help to recover any data possible from his phone.
This was the info I got from him: The phone would restart itself once in a while in the recent few months of use (almost the time that the warranty ended). The screen would black out sometimes, a physical hit on the phone helped to recover it. At the last few moments before the screen totally blackout, the screen showed the mirror image of what it's suppose to show (he had to put it in front of a mirror to read the message). And then it just died and never come alive again. He can't remember whether he set the phone to silent mode.
What I did: Removed and put in the battery, pressing power button gives me a short vibration (I assume that means it can be turned on). Dissemble and reassembled the boards, flex cables etc. No burn mark or broken connection seen. Connect to TV using MHL cable, no signal detected. Soft reset by pressing POWER + VOLUME UP button, it vibrated and screen was still black. Since then, charging after turn on doesn't shows red light below the front camera. The metal cover above the motherboard was usually very hot whenever the phone is on. I'm working like I'm blind, omg >_<.
What's wrong with the phone? What should I do? Possible to repair? Some questions I'd like to ask.
1) Using MHL, does the phone screen need to be working then the TV will show what's on the phone screen?
2) Is there anyway I can connect the phone to other external screen and control externally?
3) I'm hesitant to repair the phone, the heating up of the motherboard scares me that the phone won't last long even after repair. Anyone has this phone and how do u go about this heating issue?
