Black screen with backlight - HD7 Q&A, Help & Troubleshooting

HI every body, I have a problem and I'm asking for help
a while back my HTC HD7 felt in the sea. I managed to get it dried and fixed and it worked fine
but every now and then the screen goes black. normally i fix the problem by taking the battery out
the problem happened again a few days ago, and the screen won't turn on, when I turn the phone on I see the backlights turning on and the touch work fine and I can hear the keys and the unlock screen sound, but can't see anything
I tried to do a hard reset but the volume up key is not working so I can't access the hard reset menu.
my question .. is the a software to do a hard reset via PC. or can I use the headphone volume keys instead of the device ones???
I'm running WP 7.8 official, and a window 7 on PC.
please any help is appreciated ...
thanks

Diamond does not Power On

Hi i have a few issues on my diamond. I hope you guys could help..
1st issue: lately my diamond keeps on resetting by itself.
2nd issue: later I've learned that when I record my voice using the software within the ROM, I don't hear anything but when I record my voice using my htc headset/earphones there is a sound.
What I did was:
This day I've flashed a new rom (Energy Rom) into my Diamond. It works ok then I flashed the Radio (Radio_1.13.25.24). I was able to use my diamond for a few hours.
Now..
3rd issue: My diamond is not powering on..
What i did before this happened was...
I pressed and hold the power button for about a few seconds so the ShutXP would pop up and I could soft reset my diamond.Before I clicked the soft reset button, I was checking out all the functions of it. then i clicked, a little icon,which is the Setup Timer Action. Here's the setup:
Action: Turn Off Pocket PC
In: (i don't exactly have seen the time indicated)
As curious as i am, I Clicked the Set Action button. It did shut my diamond off. Then I tried turning it on, but all it was doing was vibrate and the screen was black. At first I was hearing the start up sound a few times but later it didn't hear it anymore. I plugged in the charger but there's no white light on the circle button which used to have a light on the borders of the circle button when plugged in the usb cable. I tried pressing the power button plus the Volume down so the bootloader would appear but it did not. What shall I do?
Are you sure that the screen working because the phone vibrate and play the startup sound so if think its the screen that have som serious problem !!
HELP
I also flashed a new rom (Energy Rom) into my Diamond before.
It cannot run window mobile6.5.........how can I do???
I cannot connect to PC .......
I recently also had a similiar problem, after attempting a flash of the Rom, the ROM update stopped halfway through and reported that it had lost connection to the device....
The whole phone would not vibrate/power on, nothing - no glowing ring around the middle button to indicate it charging at all.
I had to return to the repair centre and somehow they didn't notice that I had modified the firmware and replaced the whole phone for free citing a hardware issue ...
Doesnt sound good if you cannot hard reset the device

Diamond reboot loop w. original ROM

hi there,
this morning, without any interactiom, i heard the vibration of my touch diamond restarting.(with original newest ROM from htc website that ran without any problem for several months). battery was about 80% yesterday evening.
but it wasn´t starting at all. after the HTC animation and the green windows mobile screen, it started again. after restarting for 20 minutes i took out the battery, put it in again and performed a hard reset as stated in the manual.
now, on the "rainbow" screen i get a message like
psoc diam stage_pvt 0x32
then i did the Volume-Up reset, and now i don´t even get the red version information in the lower right screen. as it doesn´t even start i cannot get an active sync connection.
any ideas? is my phone broken? i didn´t do anything special, and i wonder why it rebooted without interaction this morning.
any ideas what i can do?
thanks in advance,
jkersch
Mine started doing this about 2 weeks ago it woke me up in the middle of night while sleeping with its vibrator and start sound.
The only thing I have found is that my little reset button at the pen holder dosent work anymore. To do a hard reset i have to takeout the battery and then put it in, hold the volume key and enter key then power it to get it. Flashed by holding volume down and the power on, it hold for about 10min just enough to get the flash.
I managed to flash it once but it dosent help, it constantly reset at the thouch diamond screen. Some times i get to the green windows mobile screen.
As warrenty is out on my phone and ive given up and using another phone.
Same problem in a different thread

Buttons Not Working and severe battery Drain

Hi hope someone can help. Over the weekend my TD2 started playing up. All of the hardware buttons apart from the on/off button have stopped working. I also notice that if I turn the screen off with a short tap of the on/off button, after a few seconds it comes back on again. All touch screen functions are ok. It also appears to be draining the battery very quickly, to the extent that fully charged at bedtime (no bluetooth or wifi on and a stable 3-4 bar signal) it will be comppletely drained by morning. As far as I am aware the phone has not gotten wet at all.
I have also re-installed the office HTC rom, which made no difference
Any ideas??
So you reinstalled the stock rom and did a hard reset?
You can try Tarkim's Keyboard controller and see if your hardware keys can be mapped to a different function.
That would help eliminate hardware vs software issues.
I have the same problem. Also my backlight keeps working and won't go off. Can't perform a hard reset because my volume buttons(and all other hardbuttons accept the on/off) aren't working.
Searched for the solution but can't find it anywhere. Who can help me?

Try clear storage app to HR.
Thanks for your reaction.
Yesterday I managed to put an official ROM on my phone.(latest from HTC site).
Problem only got worser. Phone gets complety stuck(directly after boot) in the volume screen. Sometimes its flashes back to the normal screen but only for 1 second. Buttons still aren't working so can't do anything with my phone right now( not even the hard reset methode you told me).
Started to think that this is really some hardware issue. Can't remember that water got in my phone or the phone felt really hard. Any solutions maybe?
Otherwise I think I just go to the store.

One last thing you can try is a Task29 explained here.
Use your official rom (right click on .exe and extract the RUU_Signed.nbh and place in task29 folder, then connect device in Bootloader mode and run the Task29.exe. Follow the instructions in the link.

[Q] HTC Pure Touch Screen Not Responsive

The device powers on. The buttons on the side and button work fine. The animations of the OS are working. I have tried a hard reset, soft reset, and standard power on/off. Does this mean I should try replacing the digitizer? Any ideas that I can get done by the end of the week before I go on vacation.

I think, You need screen calibration
One easy thing to try: Place the palm of your hand on the screen. Hold it there for 10 seconds. See if it works now. Helps if your hands are warm.
I've had the same problem with screen. It helps if you put your palm over the screen but it's only temporary solution. Does anybody know what is the reason for this and what needs to be done/replaced.
Would appreciate any help.

Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?
the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.
keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.
I already tried
the phone reboots well but still black screen
