Horrendous day. I dropped my phone today and lcd is broken. Screen does not turn on. However i see that the phone boots up. I can make that out by looking at the hardware keys that light up and when i press the volume button, i hear the sound.
My question is how can I factory reset the phone ?
Just connect to screen via HDMI cable
I figured other way out. Thanks for the advice

Hey all, I'm new to the forums but I can't wait to get my 8125 working. I bought a replacement screen on ebay and a broken 8125.. on receipt all I got was a white screen, then last night I replaced with the new screen and got the cingular logo and the windows mobile "touch anywhere to set up.." message.
Well, touching it did nothing, and the keyboard didn't work, so i opened it up again.
Somehow when I opened it up, the power switch button circuit thing detached from the mainboard (and it looks like the owner before me had actually crazy glued it on!!) .. and now the thing won't power up, won't show a charge light... nothing at all when plugged in or attached to my PC. So I hope that detached power button is the culprit. Upon further inspection I saw that yet another had detached but I can't seem to find where it landed... this one for the little button next to the slider, I don't really know what it does yet.. .
.. so I guess first step is to solder that power button back on and see what happens. Does it sound like a missing power button circuit thing would cause the unit to no longer power on at all (even when soft reset when connected to PC, which used to power it on?)

Argh.. well, i'll give it a go with the power switch.... do you think it will affect the phone to be missing the comm manager switch off the mainboard too... or will the phone still function without this piece soldered on?

Yes, the power on/off button being broken is the reason why you had a white screen, and only getting the splash screen after replacing the touch screen. If you're a good assembly man, I'd suggest try to solder the button back ln place or replace the device. As for the button by the volume slider, that's the comm manager button. If you can ever get to the homescreen, the comm manager icon to activate the comm manager (bluetooth, WiFi, etc. is in the system tray at the bottom of the homescreen.
It sounds to me the new screen was replaced improperly, accounting for nothing happening when you tap it.Try re-installing the replacement screen.

Hello!
I have strange problem with my HTC HD2.
I doesn't power on without charger. It only powers on with charger plugged in to PC or wall and when soft reset button (under battery cover) is pressed. So it doesn't power on with power key.
When phone is powered on it shows only black screen with screen lights and key lights turned on. I can hear the boot sound from HD2's speaker so I think it boots into Windows Mobile correctly.
When plugged to PC and phone powered on, PC can recognize it. I have tried flashing newest ROM from HTC website but no change. Still black screen whole time.
Problem came after I installed new touch screen digitizer+LCD assembly. LCD ribbon looks OK and its plugged to motherboard correctly.
Could this be software issue?
I would be very happy if someone could help me with this strange problem.

It's not software, sounds like your digitizer to motherboard is messed up somehow. Worst case is dissemble and try again.

I have assembled and disassembled it again and again few times with official htc hd2 videos but no change.
Could this be radio issue?
sounds to me like the "front" face of the phone isn't properly connected with the motherboard and rest of the stuff.
FACT 1: the front power (or end call) button isn't working
FACT 2: the screen is blank, probably not powering on and/or receiving a data signal
FACT 3: the device appears to boot for all other intents and purposes
disassemble...reassemble...pay attention to the button strip and the LCD ribbons...maybe you might see something wrong.
Also, no radio or ROM would cause this issue, I don't see how this could possibly be software in any respect.
Disassembled and assembled again but still no luck. I contacted to ebay seller who sold lcd for me. He said that he will send me new lcd + digitizer assembly.
Long story short my S5 got wet and I took it apart, but when I put it back together the volume keys aren't working. I'm not sure If I need to buy the midsection of this phone that houses the volume and power buttons or if I need to buy a new LCD glass. I think I may have cut the ribbon cable on the left side of the LCD screen. See the below image of how the two cables look like they should be connected but are disconnected. Every tear down and pics of this phone show these two cables being connected. Can someone please confirm if I did indeed cut this cable and if it does control the volume up and down buttons? I want to exhaust all my options before I break down and buy the midsection. If I did infact cut the cable then it will be a costly mistake. Any help would be appreciated, thanks

Im not sure if you did but for now you can download a volume widget till you can have it looked at
Sent from my SM-G900W8 using XDA Free mobile app
I wish it were that simple as I have another problem with my phone, but in order to fix that problem I need to fix the volume button problem. My phone is stuck in boot loop from getting wet. It's unrooted and I could access the screen to wipe data when the volume buttons worked, but even after trying to wipe data it would still stay in boot loop. Now, If I help the volume down, home, and power button I could access the Downloading screen. This screen will give me hope of reloading a new OS, but I can't get to this screen till I can figure out my volume button issue. I"m hoping some one can shed some light to my question above. Thanks
Hey!
I have an S5 Neo at work, and earlier on Friday morning it worked great, but then the screen started to go black, first it was only random and it would go back on again. But soon i had to try remove the battery and restart it, but nothing happend. After waiting some time the screen was back on again.
So when I got home I tried my best and got the screen working, did a backup and factory reset. I was super happy and tought that it had helped, because the screen come on right away. But as soon as I put the backcover on the screen started to flicker and then turned all black again.
I managed to get it working by pressing quite hard from the rear around the camera and the simcard holder. But only temporarily.
One other thing that does seem to work is to remove the battery, hold the power button pressed for some time and then start it back up, but as soon as i press in the upper corners the screen flickers, and if i press pretty much straight on the samsung logo it goes completly black and wont turn on, until I have had the phone turned off and pressed the power button for some time.
I understand that this must be something wrong with the display assembly(loose flex or solder joint in flex) or maybe even motherboard, is there anything I could try and do at home, or is my only option to send it away and get it fixed?
Hello, recently I damaged the screen on my s8 where the screen wouldn't turn on and no input would work, so I figured it was the LCD and digitizer that needed replacing. I've replaced those parts, and the touch works now but the screen never turns on. I turn the phone on and see the blue notification light that turns on when the Samsung boot logo comes up, but can't see the boot logo itself. I can unlock the phone because I've memorized the pattern/placement and I can hear the volume change sounds when I adjust the volume.
I've tried cleaning the PCB contacts, holding the volume down + power button, holding volume up + power + bixby, and I've changed the battery and verified it works. Anybody know what could be the cause? Faulty screen? The company I bought it from is asking me to send it back to verify if the screen is faulty, by I'd rather not go through that trouble if the problem is with my motherboard or something. Although, because everything else works, it does lead me to believe the screen itself is bad?
