Screen randomly stopped working...weird.

[theorie]

So, I was just using my Diamond to take a photo. After taking the photo, I went to take another and it said "Could not initialize camera" or something like that. I reset the phone using ResetManager, but when it came back on, the screen was not displaying anything and none of the LED's are working.

Now, the phone is working, but I can't see anything! I know it's working, because when it turns on, it vibrates, and if I plug it into my computer, it functions as a USB drive (I can see files on it).

Why is my screen suddenly not working? I tried removing the battery and putting it back in, didn't help. I tried holding the red reset button, didn't help.

Any ideas?


I'm using the most recent version of Dutty's rom (ignore what my sig says).

...quick update:

just reset tried to do a hard reset on the phone (hard to do since i can't even see anything on the screen) and turned it on.

when it came on, the LCD is working, but there is no backlight. there is a message saying something like "microp version mismatch 0" then "please upgrade latest microp firmware"

after that, it goes to the normal touchflo home screen, but there is no backlight.

i am going to try to load the latest (v3.4) version of dutty's rom to see if that works. if not, what should i do?

ok just got off the phone from someone at HTC USA support (866-449-8358).

he had no idea what the problem was. had me to a reset though the settings (clear device storage)

phone turned back on. still no backlight after completing all the steps.

then he transferred me to the "repairs" department. the guy there told me that he only deals with hardware repairs.

the repair dept told me that they didn't know what to do either, and told me to ask on www.htcwiki.com

apparently no one at HTC USA (or at least, no one i've talked to) knows about this problem.



ugh now what do i do?

[owziee]

What happens if you flash it with the latest original rom just to test???

What happens if you flash it with the latest original rom just to test???

haven't tried that because i don't have a copy of it...where can i download the latest official HTC rom?

at present, everything functions on the phone EXCEPT for the backlight & key LED's. the strange part is that the center (OK button) white LED does still work.



by the way, i got an email back from HTC tech support. here is what they said to do:

Thank you for your inquiry on your Touch Diamond.

I know how frustrating it can be to not have your device function the way it should. If you have any Third Paty Software on the device I would suggest removing that as a start. If that has no effect on the issue, we can hard reset the device. This will reinstall the operating system to the device and determine if it is software or hardware related. If this does not fix the issue, the device will need to be repaired.

Please follow the following steps to perform a factory default reset:

1. Press and hold both the Volume Down and OK keys (the bottom key on the left of the phone and the center, circular key on the face of the phone).

2. Insert the stylus tip into the reset hole at the entrance of the stylus holding slot (as if you were doing a regular soft reset). Once the screen goes blank release the stylus.

3. When a prompt on the screen appears asking if you wish to clear all data on the device, press the Volume Up key as indicated by the prompt.

4. Allow the device a couple of minutes to fully restart and let all device customizations finish before touching any button or tapping on the screen.

HTC Repair’s number is 1-888-617-1113. The hours of operation for HTC Repair is Monday through Friday 8 AM – 8 PM EST.

I hope we have answered your question in detail. Feel free to contact us again if you have any further questions.

I had the same problem you had. It had been going on for a couple of months. Screen which stayed black after ending a call or after some time of inactivity it also stayed black after pressing the power button. When I soft resetted my diamond it vibrated, but the htc startup animation didn't show up, also after several soft resets.

I got my diamond only working by taking out the battery. Sometimes even when I put in the battery in after some seconds, it still remained black when I turned it on. Most of the times I had to take out the battery and leave it out for some minutes. After 5 or 10 minutes I put it in and it started the normal way. But after half a day or so I got the black screen again and had to remove the battery again.

I use original Dutch stock rom 1.93 with some tweaks. Nothing special or so....I managed to install a remote control utility so I could see the screen on my laptop. One day I got the exact same error you had. So I called HTC support in The Netherlands. They sent me an email with an UPS receipt so I could send it to EuroTwice, which takes care of the repairs for The Netherlands and Belgium. I could track the repair online and noticed that they couldn't find any error. I got my diamond back last week and when I turned it on, guess what....the screen remaind black. It did vibrate when booting, but the HTC startup logo didn't show up again. The repair ticket (the paper one I got with my diamond when I got it back) also mentioned that they couldn't find any error whatsoever and that they hadn't modified a thing on my device. Bad shit.

I then remembered that I had an extra insurance/warrenty I bought that together with my diamond, just in case. I went back to the store (something I should have done much earlier) and they tested it again, but because of the extra insurance/warrenty I got a brand new diamond. This one works perfectly. Tweaked it again and my screen doesn't turn black anymore. Haven't soft resetted my device in 4 days now.

So I should suggest to go back to the store and demand a new one.

I attaced the screenshot of the error I had...Btw...I bought my device on july 27 this year and got an new device last week. Normally you can get a new device here when the product doesn't work as it should within 3 days or something. It's worth a shot....

wow long story. so i guess i'm #$^$ed at this point.

i can't believe no one knows how to fix this, when it's obvious some sort of software/firmware error - not hardware.

i've offered a $40 reward for anyone who can fix this problem, but no bites so far.

i bought my diamond online back in june or july...i doubt the store will cover it with warranty. :( maybe i need a new phone

Maybe you can send the screenshot I made to HTC and ask them how to fix this. Or at least refer them to this thread. You said you bought it online. From a webshop or 2nd hand on ebay or something ? If you bought it in a webshop it's worth contacting them.

Furthermore I don't know how the legal stuff works in your country, but in The Netherlands we have a kind of protection for customers when it comes to products and their economic life. This means that for some devices the manufacturer has to repair it for free. For instance a washing machine or television. You can expect that it lasts for a minimum of 4 years. If it breaks down after one year or so, you can take it back to the store and they have to repair it. The vendor has to prove that you are to blame for the malfunction of the product, but in 99% of the cases they simply can't. Good luck with this matter.

I'll pass on that screenshot...but who knows if it will help. HTC hasn't been too helpful so far...

anyone have any more info on how to maybe fix this?

[theorie]

anyone? anyone?

i'm still stuck with a phone that has NO BACKLIGHT!

i also just realized that the Wi-Fi is no longer working.

grrrrr....

ok $50 to whoever can fix the microp problem on my phone!

Have you installed the original rom yet?? By a full reset the original rom is not comming back only your duttys. If you did not flash it yet with original you should do it. When the problems after this stil occur you can send it to a repair shop. Normaly this is then under waranty.
No point of discussing when original rom has not been tried.
You can download original rom from the HTC site.

Grtzzzz

Hey man be sure You´re not the only one with this prob...check this:

I got this error on saturday n till yesterday I was tryin to find out somethin to fix it....the conclusion is - yesterday I sent it for warranty repair:(

Even with no display and buttons I flashed stock 1.93xx ROM and also stock 1.93 SPL - nothing changed...problem remained. I was unable to do Hard-reset ´cause "reset button" didn´t work. And very good notice - a few days before this stuck I couldn´t turn on wi-fi. I didn´t realize that it has somethin with this problem till now - I see You got same symptoms:rolleyes:

Really didn´t find the solution so only way was to send for reapir to authorized service.:mad: Off course like a warranty service n I hope that I didn´t lost warranty - couldn´t proof if flashin of stock SPL was really succesful - but PC didn´t show any errors after the whole procedure...
