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.

I've checked it, there doesnt seem to be any damage, and it appears to be connected correctly

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.

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).
my volume down button is constantly trying to turn the colume down have taken it appart and reset it and still wont stop
Have you noticed whether or not the button seemed to click down properly (mechanically), or was it stiff or what?
Seeing as how the volume down button is actually soldered directly to the main logic board, I'd say if you don't have crud that's worked its way in to physically depress or cause the button to stick, then it's probably a broken switch inside the button (sorta like adhesive switches/buttons going out), and the only way to take care of that issue would be to replace and re-solder in a new switch.
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 all!
My phone got water damaged (a little bit, the back cover wasn't properly put) and the phone now turns on only in safe-mode, even if I reboot, pull the battery or do a factory reset. My volume-down key doesn't work now, if that could be the problem.
Does anyone know what I could do?
Thank you
Mine was doing the exact same thing, except my volume-down key acted as if it was being pressed down constantly. I spilled water on it while on a cruise and it wasn't the same. My phone would constantly mute and the volume overlay was constantly visible on the screen. I had the safe-mode on reboot several times, I'm assuming holding the volume-down during boot is what activates it.
My fix was pretty brutal, I popped the volume button off with a thumb tack, then uses tweezers to rip the volume ribbon cable out of the phone. I now have to go into the settings menu to adjust volume, but at least the phone is usable. My hunch is that water damaged the ribbon cable via the volume button.
The actual fix would be to replace the frame/back housing bezel for the phone. It's only about $8 on Amazon (http://amzn.com/B00K458DUK), however it requires removing the screen. My phone has been dropped a few times so I'm worried the screen won't survive a transplant. A replacement screen is $150, so I've just been dealing with no volume control for now.
I see... thanks for your input! I'm guessing mine is having the same problem. I'm not comfortable doing the brutal fix myself, but I don't know where I could take it around here to get it fixed.
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?

Sorry but you are pretty much done .
Have you broken the buttons? D'you still need any help? I mean it's been so long, you might have already fixed it.

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.
