Killed my MDA II Compact?

Dear Forum Users,
fist of all sorry for the fact that my first post is a request, a question and not a contribution - but im really dependent on your knowledge.
Despite the fact that in general it is not recommended to change the cover of your mda (or xda etc) I did it, and seem to have f***** up my display. The device itself is working just fine, i can do active sync, the taping also works (when i switch it off and guess where the yes button from "do you really want to turn off your device" is it actually shuts down properly). the thing is that i dont see anything, its just plain white.

when dissecting the unit i disconnected the connector from the display to mainboard in order to unmount everything (unfortunately i discovered afterwards that i could also have done it without connecting - dumb philipp :/ , but right now that doesnt change anything for me)
has someone dealt with a problem like mine before? i would be really thankful for any hints or advices to get my baby back to life, otherwise my old vk2000 will be my companion for the next 6 months (i shiver when i just think of it).
thank you in advance,
Philipp

Have you tried to disassembled, and than reassembled it again?
some times the display flat cable, isnt fuly inside the connector...
there is a possibility that you f*** up the connector, but for determine that we need a macro picture of it.

yes i messed with the connector indeed, but as the pins of the strip were down i thought the black piece wont be of that much importance (i can remember i ****ed one up at a regular mobile yrs ago and it was still working)
can i get that thing back to life if i try to squeeze the 2 black parts (formerly one piece) back in or do you say its over?
thank you for your quick reply btw, i appreciate!

That is not good. i dont think you can do anything but send it to repair. maybe they can replace the connector.

ok, i will call them and check how much it is and if it is even worth having it repaired... if not, then i have a defective compact for sale :/

shayd, thank you!

No problem at all

this guy has a bricked Charmer. Probably you can talk to him and see if he is willing you sell you the charmer as parts.

JasJar Faulty Screen - Video Evidence.. Please help!

Hi all. A while ago (read last November) the screen on my xda exec, aka jasjar mysteriously started acting up.. I've posted a quick video of the issue on you tube.
Link here: http://www.youtube.com/watch?v=EjV-1WRC714
As you can see putting the screen in landscape, specifically in "laptop mode" causes the screen to lose connection with the device.
Anyone know if this is something I can fix myself with the right tools? What do I need? Screen itself is fine, looks like a cable/connector problem. By the way its out of warranty and second hand... so I'm on me own..
Would a soldering Iron do the trick or do I need a new cable?
Any help/advice appreciated! i was loving my exec until this happened.. replaced it with a symbian phone... and now... well its time to go back to windows!
Cheers again,
wab.

LCD Coax Ribbon has gone. Happens a lot, and it happend to me, they cost about 70.00 GBP but i have seen them cheaper. Replacing them isnt the easiest of tasks, but if you have a steady hand, tiny screwdrivers and patience its possible. No soldering is required. The cable clips are pretty easy to remove and install, its just running it through the channels and the hinge.
Did i mention you need a steady hand??
I Did find this....

Steady hand... umm...

Mmmm. Tricky perhaps. A hard reset will either cure or leave you stuck. If you hard reset and the screen is indeed dead (touch wise) then you'll never get past the alignment stage. If the touch issue is software related then you would be sorted with the hard reset.
A gamble I think!!
However you are stuck at the moment so in a sense you have nothing to lose. If it ends up being useless then you are faced with a warranty (hopefully) repair otherwise some DIY though it's not entirely obvious what has broken/come loose - possibly just a ribbon connector.

Maybe the ribbon cable came loose on the LCD side?

Yeah i think its that as well, i hard reseted it a few times with no effect, in the begining of the day, it could still reconise the screen taps around 2/3 times before it totally went dead.
Are there any tutorials on how to open it up to check the ribbon?
Thanks.

This maybe the hardware problem with the mainboard itself. I read about this on here a few times, most people had the get their phones exchange....

Yes, I am equally unsure that this is just a simple loose connector. It may be, but it appears to be fine for a short while and only then goes off.
Like you myztikal47, I suggest going for warranty replacement if at all possible. Only if you have no warranty shuld you attempt a repair yourself - this is a notoriously ellusive fix and indeed I would say there is no 100% works for all answer. Certainly do not assume it's the screen - most probably it isn't and you'll waste your money.
There are dismantling links in this forum - but you'll find them on my small Hermes site http://michael-channon.spaces.live.com- go to the loose keyboard section and you'll see the links.

my 8525 had the same exact problem, and i swapped the LCD and still doess the same thing...
I dont know what the problem could be, and i dont have a warranty.
What could be going on????
Any 1 know where 2 find the service manual????

Touchscreen problem

Have a "small" problem with my touchscreen, it requires to be aligned every day,and by that i mean that the alignment doesn't hold much long...that means sms typing is extremely hard when you push one letter he shows you another that lays next to it .Is it due to the touchscreen or the system....i didn't do any ROM update i still have the original software on him:
ROM Ver.: 1.12.01 GER
Radio Ver. : 1.12.00
ExtRom ver. : 1.12.151 GER
Many thanks!!

i think it it the problem of touch screen
i think it it the problem of touch screen.after extrem use of touch screen its loes the alinement for this you replace the touch screen from your hardware guy.
Thanks for all

Hi i fixed the problem with a ROM update and i didn't install extra programs that i had before like ( Pocket plus or Calendar ++...... ), anyway now i don't have to align the screen. I don't know is it the ROM update or the additional software but the touchscreen is now working perfectly.
So if someone else have a similar problem don't replace the screen right away.
Thanks

it's hardware problem.
my xda mini also..
but i know how to fix this problem.

Maybe with you it was, my MDA is now working perfectly and i don't need to align my screen every day as i did before.That doesn't mean that all have such a problem,i am only telling you my experience with it.
Best regards from Vienna

Hello, in my magician is not everyday, hapens all the time that i turn on it.
I had replace it 3 times, but i can find a good dealer of touchs. You knows one that seel a good touch?
regard's,
Ricardo

Guys,
I've had that problem for a LONG time and today i finally got tired and decided to fixed it...here's how i've done it: You just need to lift a little bit up, a few small metal pins which are all around the touchscreen (see the picture in attachment). This will force the touchscreen to remain in place and will end all your problems related to touchscreen alignments.
Regards,
Keeper

so it does help? what do these pins do?

IS THERE REALLY NO SOLUTION TO THAT PROBLEM???
(* the pins have nothing to do with the touchscreen, they are what holds aluminum shell on the plastic chasis)

i had an o2 mini with 1.11 rom and its touch screen was not quite sensitive.. had to tap or drag stylus very hard..
but after upgrading to 2.03TX.. to my surprise.. my PDA now has very good touch screen response!

hi, i have this problem
I tryed to re-flash rom or adjust metal pins but the problem persists.
Anyone have another solution?
Plese help me, i want to save my pupil

i have the same problem. the o2 is really a great little phone but i think im going to be forced to upgrade

i also got a unit mini xda from a friend, he said it is dropped and can't tap screen. i hold and press the screen, then slide up and down, side by side, and now its ok.

Probably it's problem with flat wire that connects screen with mainboard.
You need to open yours xda, find that wire, unplug it from mainboard, clean its pins with alcohol and plug into again.
From this time mine xda doesn't decalibrating anymore

Hi
My cell also had the same problem. There is a bunch of wires coming from the back of touch screen, these wires fix inside a socket. There is a black color cover that fix the wires inside that socket. During mishandling that cover got loose, that's why your cell loose the screen setting. I fixed that cover and now my Jam works perfectly. (Do it if you have the courage to open your cell)

Hello, I just bought a used O2 mini and had this same problems. I finally found a quick way to restore the calibration that goes out every restarts.
Using resco registry editor, I found the data stored here->
HKEY_LOCAL_MACHINE/HARDWARE/DEVICEMAP/TOUCH/CalibrationData
So I make 1 clean alignment and quickly went and export the Touch key into my Storage. Now every time the alignment goes haywire, I just import the data back. Hope it helps.

HTC HD2 Freezer Trick Only Way to Make the phone work, Could it be overheating??

My htc doesnt turn on or work or charge unless i make it really cold like putting it in the fridge or freezer for a couple of mins, then it turns on by putting in battery and sticking in usb (because my buttons have snapped the flex cable) anyways it turns on and i have this russian rom flashed by previous owner, i managed to sync it with active-sync and i clicked explore it has wierd folder names like "?????" i click delete but windows doesnt let me because it says the filename should not contain "?". Then after a couple of mins maybe 2mins the phone switches off then vibrates 7 times then sometimes loads at htc splash screen?
and to make it work again ill have to make it cold again???
some details
Its a T-Mobile Version
The phone doesnt get hot?
its running windows mobile 6.5 daltt roms
and i updated the radio to Leo_Radio_15.40.50.07U_2.12.50.02_2

I think your battery is missed up, you need to replace it with a new one. try ebay.
as for the files with weird names, if they were located in your sdcard try to run checkdisk or scandisk from your computer to fix those errors.
you might want to reflash you windows rom and format your sdcard after this to prevent it from happening again, but don't forget to backup first!

Thanks for the reply!
Thanks for the reply by the way i havent got a sd card in the phone and i really dont think its the battery problem as it charges it up fine?
i was thinking i need a new motherboard as cpu is overheating but im not sure thats why im asking!

My HD2 acted like that (needed to put in fridge to work). Sent it for repairs and they replaced the motherboard.
Cheers

Yes mainboard CPU BGA issue probably.
you might find spares on this site or try buying one with a broken screen & you will have mainboard & button parts you need plus other parts can be sold on to recover costs ...

Ohh well i dint really want too spend money...
anyway what about that guide the one about thermal problems htc hd2,
would that work??
can you also tell me where i could find a motherboard thats working in the uk and could you give link please
thanks.

Please ive got no phone
ive got no phone!
please i really need help, dont leave me.........

The thread on solving the over heating problems is a thread on how to make a different heat sink for the HD2. And also heating the processor up to maybe solve the issues of the balling of the processor as the processor itself can not be removed without making the rest of the main board unusable. But the process that you must go through in that thread is not just for your average Joe to do. If you mess up you will be forced to replace the main board. So my advice to you if you are not skilled at such technical repair work is to just buy another mainboard or a HD2 you can harvest the mainboard from, oh and it needs to be a mainboard for the T-Mobile version too as that is what you have.
I have a personal theoory about why the freezer trick works. First is the obvious thing that it cools down the CPU and NAND chip and allows it to operate for a short period until it warms up again. The second is that cold makes matter shrink slightly, those causing a CPU that has lost some of the connections to the balls under it that make contact to the mainboard to temporally become reconnected.

newbie guide please
Okay I think for my last resort I'm going to do the guide in the thread but can somebody PLEASE make a super easy newbie tutorial on how to do it (I know it will take time but please),without the expensive equipment that I don't have. Could I use a lighter or a candle or what about the oven or a hair dryer anything that would be at home please.
Oh yeah who ever provides the information that works I will donate money to you! Only if it works (yes I do want my mother board back)

Too Late
