MY HTC diamond does not switch on neither does it charge.....please help :(

Hi, I have been using my HTC diamond toch for nearly 2 1/2 months. a few days ago, i did a rom update using Dutty's rom update. All went fine duing the update. used the phone for about 5 days nonstop, no issues at all.
But yesterday all of a sudden the phone has swtiched off by itself, now it doesn't switch on. Thought the battery might be dead so i tried charging but the enter buttton area doesnt glow and there is no sign of charging.
I switched batteries with a friend to see whether it was faulty but it is in good condition.
What do u think the issue will be ?
Thanks
Buddhi.

I have the same problem. I've just got my phone back from being repaired as the touch screen got all messed up and now it won't charge. I plug it in and the touch pad does the charge animation twice then stops. It'll randomly try to turn on but it doesn't even get to the point where the red writing apears before it turns off again.
Help?!

same problem here

Dudes.... Chill!!!!
Here's what you can all try ....
First you guys need to know that de HTC does not charge if the rom is inconplete/damaged .
And.....
If your batery is realy dead there is no initial power on the internal battery to manage the chargement.
So ... resolution.
Fist way .
If you know any one that may have an other HTC Diamond you need to swamp batteries so the good Diamond that has the internal bat ok and charge it there.
Second way . this one i did it my self .
Go to a Local ChinaMan store and buy a multimeter and a regular Universal Adapter.
Heres how it hoes ...
Use the Multimeter do figure out the polarity pin's on the battery ex: + and - .
remove / cut one of the plug's from the Universal transformer and also tag the polarity.
set the voltage to be close to 5 V - 1 Amp .
Can be 4,5v or 5.5v no sweat
Conect the cuted wire from the Univ. Adapter to the Diamond Battery respecting the polarity.
Leave it for a wile..... ( Probably up to 1 hour but chec from time to time tme battery temperature and if possible a reading on the bat voltage levels.)
Done!
Put the battery bat and boot your diamond or turn on to boot loader.
**** Attention if you don't have more than 50% of the bat charge compleated you wont be able to flash your phone****
Any questions Just reply back.

same problem...
its just...my battery was full before the upgrading...i was Unlocking my Diamond..and the upgrade didnt move more than 0% just when i looked on my mobile...there was black screnn...pluged it out..tried to power on..nothing..tried to charge...nothing again..i tried hard reset(vol down+power+back+reset)..it just wont turn on..please help me..im in panic

Help, I have the same problem and my battery was fully charged before this happened. Voltage reading is 4.2V on the battery.
I also tested the power button and there is nothing wrong with it, it conducts when pushed.
Usually pluging in the charger should start it up, but it will not start.
Anyone have any solutions?

I couldn't fix mine so phones 4 u replaced it with a touch hd

I had the same exact problem two days ago.The phone was not charging while it was on,and when it was off it did that charging light animation twice and then third time the litght managed to get in the middle of the button and sudennly stopped. So here is my solution . I'v managed to charge the battery on another phone and turned my Diamond back on. While still attached to charger and power source i'v performed a soft reset (by pressing the reset button beneath the stilus) ...the phone reseted and now it's all ok.

I had same problem , no solution yet.
When I had a Mpx220 I had fixed changing a fuse, but I can´t see nothing in internet guides or foruns.
If someone knows how to repair tell us, becouse htc service in our country isn´t good and my device is outdate warranty.
Regards,
Gus

Someone has fixed?

Xperia won't start

Hey Guys,
Before going to sleep last night I connected my Xperia 1 with the original SE Charger. Today it doesn't do anything.
I already removed the battery for a few minutes and tried the battery of a friend's X1. But it still doesn't boot.
Any ideas?

Is there a red light by the power button when you try to charge it?

no there isn't even a red light

maybe try taking battery out, charging the phone itself for about 15 minutes. then after that, put the battery in again to try to power it up.
when you charge the phone without the battery, the red light on the power button should be turned on. if not, i'm guessing there might be a possible short circuit.
IF it is a short circuit in your phone, then you will have to send it back to sony ericsson to get it fixed.

Good morning friends. I too had the same problem. the phone wont start up in the morning.... However, after 3 hours, i tried connecting the phone to the charger and then pressed the power button,,, to my surprise the phone started up. But, the battery is completely drained and its at level 0. I wonder how does this happen. I have kept the phone for charging for whole night but the charge remains 0. I doubt the battery. can any one help?

Do you charge through USB/computer?

No brother, i charged through sony ericsson original charger. However, i was doing the same since i bought it.... But it was a one time go and after that this issue didnt turned back. The small remedy for this is take out the battery and, press and hold the power button to drain the static charges present in the circuits of the phone(These static charges are formed due to regular use of phone without soft resetting it(once in every two days)) . Once the phone is free from static charges wait for some time and then put on the battery in the phone and then try to turn on the phone... Believe me, it worked... This is not a phone for me... its a mini laptop integrated to a phone.

There are several threads about this. Search for the "xperia broken red light under the power buttonb" thread, it is very good and has many solutions.

My xperia doesn't take the charge!

Hey, dunno if some one had the same problem but my xperia doesn't take the charge.
Its appened when the mobile has terminated all his battery, and know the charge is not accepted by the phone
help me please

Something perhaps similar happened to me, i ran my battery completely flat and then could not switch the phone on even when it was on the charger. So I left it on the charger for ~1 hour and then it switched on fine! The other possibility is that you battery is dead. Hope this helps!

Its not the first time its appened to me, and the first time i had the problem i try a lot of time to recharge it, take out the battery, replace it etc.. and its worked.
But in 2 days, my phone is off :/
My battery is not dead i know, but how to recharge it

I have 2 computers from which I load it with usb cable. For some reason Mac Pro doesn't load the damn phone but Macbook does.
Try switching your "power" source. And sometimes when the battery goes really flat it needs many hours to even boot when loading up. One time I really thought the damn thing was dead for sure... But it came back to life
When you press the power button there's a red light next to volume buttons indicating it doesn't have enough power yet to boot up. If there's no red light then it's not charging at all.

Just leave if plugged-in and it will charge. It takes some time before it will charge if it is fully drained.

Ok thanks for reply
Have no real solution, but have the red light near to the volume button, or in the top of the phone.
But the phone doesn't take the charge at all...
The red light gave the battery charge, only that... have it sometimes and sometimes havent it...
Help me please
2 day less my phone know..

Ok i dunno why but the phone weak UP !
NICE
Ir was connected to the cpu and i presszs the button and it weak up
omg this phone

(Sort of) got it.
I'm not really an xda developer but id do have an xperia.
The same problem occured to my device about three weeks ago. I've noticed that the phone would still charge in the computer, but not by the power net adapter. (it must be broke i guess)
Today i've locked myself out calling the battery flat. I couldnt get it on anymore. After a lot of hassle this was the solution for me:
1) Connect the phone to a computer. Don't try to turn it on! Leave it there for about 15 minutes.
2) Disconnect the phone and pull out the battery.
3) Hold down the "on" button while inserting the battery back.
-- It should turn on now
4) Release the on button and quickly connect it to your computer again.
Hope this helps.

I just remember the red led lit on at the on/off button and the red light disappeared after 5 mins or so and i left for breakfast while it was still in the charger and by the time im back from breakfast, it turned itself on and was charging up

optimus black doesnt come on unless charger is plugged in

hey guys, my rooted 2.3.4 stock gingerbread optimus black doesn't come on unless plugged in to the charger. the issue started 3 days ago when i was playing virtual tennis sega and it was connected to the charger. at first my phone got very hot and then it restarted.i continued playing the game after it restarted and it later got hot and again went off, but this time blinking as it went off. i removed the battery and put it back but it remained same. i later removed the battery for a whole day and inserted it back the next day but it remained the same. i later plugged it to the charger and it came on and booted all the way to my home screen. i could even use the phone normally, but anytime i remove the charger it goes off. also, anytime i put on the camera while its plugged in it goes off and shows the battery icon charging. i have done a factory reset but its still the same. please help me.

Try another battery
I think it might be loose or dead
If it was software...it would have turned on

could be your battery, hard to tell though, what if it's pluged to the PC?

I had the same issue.. i lost the warranty due to "bad use" and send the phone to a repair center.. It has a broken wire of the USB connector.

If your phone still turns on while pluged to the computer you can use smartflash to go back to stock rom and this will get you back to warranty

phone still wont come on without charger

I had the same problem(when i got it into a pool), humidity got into your phone. As i know from my experience the phone doesnt get damaged(mine was working well for about 1 hour before end up on a bootloop) but you will have to leave it into rice for 5 days to dry(with covers open of course ) i saw this solution from another member which said it worked (sadly i didnt know this trick and i went to a service center which took me 30€ to "repair" it)

Booted but shut off

You will have to leave your phone into rice in order to dry (there is humidity in the phone) after drying(theorically as i dont have use myshelf this metod but hear it from others) it will work fine. If that doesnt work get it to a service center.
(mine as i said was also working fine for some time)

I will try your suggestion

dead means broken so you will have to change it

The board will require full cleaning and a reflow.
Not impossible, but you need to open the phone.
You will need some 90% Isopropyl alcohol, q-tips and a stiff nylon brush and some no clean flux.
Scrub motherboard to remove corrosion, coat in flux, reflow with 400 degree heat all over for around 4 minutes.
Try again. Look on youtube for more info. Or "lose" it and claim on insurance...

Sorry but same problem!
JUST 4 HOURS AGO I WAS CHECKING WHATSAPP AND SUDDENLY PHONE LIGHT GONE! I PRESSED POWER BUTTON BUT NO RESULT! I thought the battery just drained but then i tried charging it but it only shows red light. I also do the hard reset and even pressing the power button and the volume up(force restart) but still it's not opening. I tried to repair it using PC COMPANION but my pc cannot recognize it. Whenever i unplug it the red light goes off! without external power no light is showing
worst case is i had activated msc mode before that **** happened! :'( Pleaseeeeeeeeeeeee help me!
