Long story short the screen never turns on, theres a tiny bit of backlight though and apps are working in the background. I've tryd updates and so on, nothing fixed it.
So my final resort is to change hardware parts...
The thing that i think the problem is, is a faulty motherboard. Is there any way in particular that i can try to test and make sure that the screen really isnt the problem here?
Power + Volume Up buttons or the Reset button under the flaps, it will shot down, then power on the phone, do you see any image? (Sony logo, bootanimation)

nope, nothing. just a tiiiiny bit of backlight. phone boots up in the background though, you can hear apps opening and virations

Then the LCD is dead, the backlight working but nothing else, this is 100% hardware failure.
without a bespoke hardware testing kit you won't be able to test the parts, changing a part out would work but then you wouldn't know what to change out. could be a few things, loose flex cable, dead backlight, broken inverter (if phones even have them), Broken motherboard.
The list goes on m8, if you can MHL out of the device and go back to stock then I would do that and send it off for repair.
If thats at all possible.

Hi, recently my extUSB broke down, so I was unable to coonect anything. My friend changed the connector in proffesional way with IR gun. But now Kaiser won´t even boot up, no vibration on startup, only green LED is lit up.
I bought D2, but I am curious if there is any way to fix it.
Thanks in advance
What does your friend say?
What happens if, while holding down the camera button (on the same side as the power button but further down), you press the power button to power it on - do you get a stripy screen? If you do, you can poke the stylus into the reset hole to reset the device out of the bootloader screen. What did the friend have to say about it - personally I'd much rather have a TyTN II which boots and works fine except for a broken USB port (I presume it was working fine before the 'repair'), than one with a shiny new port that won't work at all.
Nothing happens it looks like it is absoluttely dead.
The USB port was faulty, that was reason, why I let it change.
Well, it is strange, but actually I am very satisfied with with D2, even more than with Kaiser...
Well I suppose you could always get an expert to look at it but if its motherboard is damaged (or there's other hardware damage), it may be more expensive to repair than it's worth. You could see what your local HTC people have to say about it.

Or you could sell it in the market section, plenty of people that would like to get a crack at fixing it or use it for parts.
Hi, I just encountered the very same issue. I know I'm ressurecting a very old thread, but I rather do this than creating a new one
I flashed my Kaiser with Android about two months back. Everything was quite stable, no hardware issues. Suddenly, it won't turn on.
When I plug a charger in the extUSB, the orange LED won't show up. And if I try to turn on the phone, the green LED shows up and stays solid. However, the short familiar vibration isn't there and also the screen remains black. Nothing was wrong with the USB port. I tried multiple chargers...

Have you tried to reflash or hard reset?. Also maybe your battery is gone..try another one.
Some things to try

I realise you cant flash if it's not booting but if your battery has sufficient charge remaining (won't work if it's flat) it'd be worth trying a hard reset using the D pad key + stylus in the hole method (can be done at switch on time without needing a full boot).

How do you know that a fault hasn't now developed with it - I wouldn't rule that out at this stage. Have you tried a known good battery that is fully charged in the phone also is it the original charger you are trying (not all chargers with the same plug are compatible)? Are you able to get the bootloader screen to show and if so, what does it display?

No bootloader, no nothing - just black screen (there's not even a hint of backlight). I'll try a different battery today.
I tried using my old AC charger, my colleague's AC charger (for TouchPRO2), USB cable... the orange LED still doesn't come up.
What's the hardreset using Dpad key? I tried holding the power button + camera and also holding the two "context" keys (above explorer and messages buttons) and touching the reset button with the stylus.
I'll see whether a different battery will do the trick.
Thanks a lot for all your suggestions, guys! Much appreciated!

The context key one you mentioned is what I refer to as a D Pad hard reset. The one where you press the power button while already holding down the camera button is how to get into the boot loader - it's all explained in the Kaiser wiki. Sounds like another battery is definitely worth a shot - especially if you only have one (I have 3 for my Kaiser and on some days with heavy GPS use, I need all of them). What happened between it working and not working - what were you installing or doing with it?

I tried another (fully charged) battery from my gf's Kaiser today. No change. When I press the power button, the green LED shows up and stays solid (no blinking/flashing). Screen is black, no short vibration. I tried all sorts of hardresets and also tried to get into the bootloader. No luck.
Also, I took my multimeter and measured voltages on the charger, the battery and the pins in the phone where battery resides. Everything seemed to give a correct voltage. So it's really not a power issue
Thanks for all your help, but I'm afraid I have a total brick in my hand.
My Kaiser
Hi I have a HTC Kaiser I bought the first week it came out and it was f=ine for quite a while but 6 months ago it stopped working. It'll go to bootloader but won't flash. When trying to turn it on it'll go and just get stuck on the splash screen. I figured it was a battery because I'm very hard on my phones but I just got a replacement battery last week and all 3 of my batteries act the same way. I may have been trying to flsh went it went down it was a few months ago so I can't remember.
--- Other things to note
My Kaiser got wet and I had to have the usb port replaced and the dpad replaced. The usb acts fine but the middle dpad button does not work
The charging light will stay orange or green after I unplug the charger
After reading for the last week I think its either bricked or maybe has a bad hardspl on it?!?
Thanks in Advance for any help you guys may give.

Time for it to visit the same phone repair shop (or HTC) again for an assesment/possible repair if economically viable. If it's only recently got wet, you may be able to catch it before corrosion sets in and causes any damage but if it's not dryed out/cleaned quickly, the damage (from the resulting corrosion) will eventually show up (possibly in all the ways you've described).
Hey all
I disassembled my Touch Diamond to see if there was a bad solder on the mini usb (It would only charge if the cable was held in a certain way.)
I couldn't see anything wrong so I put it back together, but now the screen (The keys also dont light up) doesnt come on? But the phone seems to boot up fine, if I leave it for a while and I press the power button, it'll give me the sound to shut down.
I've also noticed if I press the volume keys, the screens lights up very slightly.
Any ideas?
I've disassembled and reassembled it a couple of times now, cant seem to find the fault.

OOPS!
Try inspecting the ribbon cable that connects the lcd screen and digitizer to the main board. You may have unhooked it somehow or possibly damaged it.

You said earlier that if you push the volume keys it will sometimes light up...that sounds like a grounding problem. Check and make sure something around the power button is not askew. Also, (and this may sound stupid but trust me on this) don't tighten the screws down too tight. It messes with the d-pad.

Hey
Thanks again for taking the time again to reply.
Opened her up again a couple of time, still no luck.
I've tried various screws at different levels of tightness, still nothing.
I wish I knew what to tell you to try but I don't.
I guess take it in for repair so they can diagnose what the problem is.
ok so i've been using it a bit but my battery was 70% last i checked. was playing around with throw and just opened youtube and the screen flickered a bit (black lines) then decided to go black completely.
nothing i do will make the screen do anything.
holding the power button for ages (usually the way to turn off/reboot a phone) doesnt do anything. the backlight is on as i can see that. but nothing is on the screen.
anyone got any ideas on how to force a shutdown/reboot on these?

IIRC the Xperia Z1 has a hard reset button under the sim flap, it's a small red button, give it a shot.
remove sim card and sd card and try again, if it's still not responding do an update repair using SUS or PCC
BTW there is a known fault with the XZU and it could also be on the Z1 as they use similar Firmware, what people have found is that the phone will start up eventually and then they go into the display setting and untick the auto backlight option and that fixes it
I also reboot my Z1in this way when it blackout.

Managed to hard reset using power and up volume .
Put it on charge overnight but it doesn't see,m to have taken any charge at all....just trying again using diff PSU and cables but it doesn't want to charge. It recognises that I've out a cable in as I played with the smart connect setting. When it is off completely I get a red light (presumably meaning its charging ) but not in android
Any ideas?
Got it charging again by pushing the red button near sim slot for a couple seconds.
Just had another issue with SD card not being recognised after I removed another (/safely) had to reboot again using power plus vol up as it stuck on the shutdown logo when I tried to power down'...
Wow I can't believe the amount of issues I've ran into within 24hours of having this thing. I really don't know what to do...return it because it sounds like a faulty device (but all the issues are seemingly unrelated) or return and get another phone (is anyone else getting problems like I am?)
Sometimes phones have issues. I got one once that had no speakers or Mic inside... it happens lol
Try to go exchange it, and see if the next device gives you issues.. if not then you're good, if it does pick a different phone..
Do it soon though, most carriers only have a 14 day exchange period, and then after that will charge you all sorts of fees and try to fix your phone rather than just giving you a new one....

sounds like a similar problem I had with my 64gb SD card - as I mentioned above remove all cards then start from there - a reflash of the firmware might help also

Something happened to mine with Youtube too. I'd started a video and paused it on a frame for comparison with another screen. While I was setting the other phone up, the screen on Z1 timed out. I pressed power, the screen come on and flickered, then went black!
Power and both volume keys function the same as the red button under the flap. I wasn't able to reproduce the bug.

yeah i've been trying to reproduce it and failing to. very odd. maybe its something to do with the first time you use youtube and do something specific?
gunna phone o2 up tomorrow and see what they say about all my issues. seems to have been fine this last 24 hours though and in their eyes that is prob reason enough not to issue a replacement.
I've had mine since Monday and this happened to me yesterday. I was troubleshooting sending MMS with T-Mobile tech support (not a phone issue as it was happening on previous phones too) and had to restart the phone several times. I noticed upon restarting that the backlight seemed to be on but the phone was not booting up. Had to perform several hard resets (both with the red reset button as well as the power/volume up buttons) before it FINALLY rebooted and stayed on. While trying to figure this out I ran a Google search to see if others were having this problem. One solution was to make sure the backlight option is checked. I had been messing with settings the night before and must have unchecked it. Since I rechecked it I haven't had the same issue.
Figured I see if anyone else has had this issue. I went for a walk with the dog yesterday, and was listening to music on my Nexus 6 the whole time, and when I got home I couldn't get the screen to turn on. Music was still playing, it was still connected to my G watch, and holding the power button triggered a vibrate when the power menu opens--but the screen was completely black and unlit the whole time.
Had no prior issues, just wondering if anyone else has had this issue. Figuring I'll probably call Motorola as this seems like a hardware issue...
Any suggestions would be well received!
Try holding the power and volume down buttons together and see if the screen will come on when it reboots to the boot loader. Alteratively you could try to power cycle it by holding the power button down for 30 seconds. Hopefully Motorola will also be able to help you.
me too
same exact thing happed to me music pulled out headphones the phone still works but the screen is dead. I can pull to use phone and **** and have the same vibration. holding power for 20 seconds is a no go. tried tons of holding combinations it seems like I can get it to shut off and on may be but it's just not doing a reset that I can tell that reboots the screen.

Ambient display fault?

same problem
Okay so long story short, I accidentally ripped off the entire button strip from the motherboard while I was replacing my LCD (well there goes my money) so I cannot press any buttons. And consequently I can't power on the device.
The only way to turn it on now is to charge the device, but then the charging screen pops up with a button in Chinese. No biggie, right? WRONG!
For some reason that button on the charging screen cannot be pressed, so I don't even think the touch screen is enabled.
And I tried ADB while on the charging screen but to no avail.
Can anyone here tell me any other possible solutions to this, or did I pretty much just FUBAR'd my K3 Note?

Yeah I eventually got myself a button strip replacement from Aliexpress, and I soldered it on which took so many trial and errors until I finally got it working. With regards to the whole phone itself, it's still not functional as the LCD is damaged. I have another replacement LCD but the stupid thing came with some "quirks" that needed to be fixed with a dremel tool, but due to my laziness and the fact that I don't have a dremel tool, I just forgot about it.
