MDA III - Broken screen - how to fix?

Hello,
I bought an MDA III on eBay. Came with an English ROM.
Recently, the screen got smashed (was run over by a car). Thankfully, it seems only the screen was smashed and the phone/PDA is still okay. I can even still syncronize it with my computer. I just can't do anything else with it because the screen isn't visible.
My question... How should I go about getting this fixed? Is it possible to buy a replacement screen and fix myself? Is there a vendor that can fix for me? I would ask the origianl manufacturer, but it is German.
I'm attaching a picture of it to give idea of the damage.

Problem!!!!! The Screen Turns Totaly White

Hi
I have the Official HTC WM6 ROM installed on my jasjam, been using it for over a month now but now suddenly the screen turns white and the buttons don't work too. it just turns white, only when i soft reset a few times does it come back on. Anybody having this issue??
HELP
Try a Hard Reset but you'll lose all your information.
Hope you backed up!!

Thanks so much guys
but i didn't seem to find a solution here, i have the 2.10 - Hard-SPL-V7 flashed.
do you think if i revert to the Orignal Imate WM5 Rom would solve the problem??
Please help me here, i gather its a software issue not a hardware one.
Thanks
It's more likely to be a hardware issue. I had the same problems, some times the hardware buttons from the lower part of the Hermes doesn't work, some times I got a lot of white screens, regardless the WM version. Finally I send it to service and now everything works flawless.
It's a hard problem. I have seen this problem on a french forum.
I have found a link to correct this : http://cnn.cn/shop/8525tytn-flex-cable-p-1732.html
And the topic in french : http://www.forummobiles.com/index.php?s=&showtopic=102083&view=findpost&p=1415329
No more link to this piece on cnn.cn
Thanks a lot guys, luckily mines under warranty so will take it to the guys.
thanks again
cleaned my connectors with alcohol and now everything works
hi,
how did you do that??? can you please guide me please?
Thanks
open your device
disconnect the connectors
and clean both sides with alcohol
Thanks but a little apprehensive to do that, do i have to disconnect every connector there? i mean that could mean disassembling the whole unit, was the white screen for you reoccurring constantly?
white screen
even I am facing the sam issue... screen goes white and lower button wont work... this is mostly becoz of over heated or expossed in sun ... Do any one having actual solution for this??

Sony xperia z1 compact touch screen problem

Hello,
My problems with the phone begun a month ago when I broke m display. The phone is out of warranty so I ordrerd a new lcd with touch screen. I removed broken one and connected new one to test it. Phone turned on everything worked fine, but after 5 minutes touch stopped responding. I thought display is faulty so I bought another display. Result was the same. Phone turns on but touchscreen is not responding. I tried hard reset, cleaning connector for screen, but no luck. Can any of you guys help me solve my problem or do you have any idea what else should I check?

Wifi Bluetooth Antenna problem with connection

Hey guys,
I have a problem with my OP3. I dropped it and it had a big dent on the back. So I decided to open it an try to press the dent back into shape.
After reassembling my Wifi and bluetooth are broken. I can get connections but the range is realy bad, about 5m for Wifi till it disconnects and about 5cm for Bluetooth.
I opened it a second time to take a look if i missed a connector or something and i saw a clip (those small things that connect to the back of the phone) was broken so i ordered a sparepart (it was the headphonejack circuit board) and changed it but its still not working.
Does anyone know where the bluetooth and wifi antenna are positioned ?
Have i just broke my phone or can i change something to get it back to work ? Everything else is working fine.
Thanks in advanced
Dennis
Same problem here! After I replaced the screen I lost my WiFi and bluetooth connections as well. WiFi is working in a range within 2m.
Is changing the coax antenna cable a solution?
Many thanks in advance from me as wel
Ken
Glad I'm not the only one, so maybe we get more help when more people have the same problem.
I changed the backplate cause of the dent and because the antenna is built in there but didn't change anything.
I have ordered a coax cable and will replace it when it arrives, could be today. Will post afterwards if this helped, but I'm not realy confident in that because i haven't done anything with this cable while repairing.
Maybe someone knows more about this, i just don't get why it is working but has no range, makes no sense to me ...
I have opened my phone several times now, but nothing seems to work.
Do you have an update on the coax cable yet? I hope it works, or the one plus 5 has to hurry ?
Hey there, same for me, opened it up to 10 times now but nothing helped, coax cable was a failure too. I realy don't know what it could be.
I'm about to wait for the OP5 or get a used 3(T) depending on what the . Was thinking about getting one with cracked screen and change everything but not sure if i should try it.
I have the same problem now. Any updates?
Hi guys! Yesterday I changed the camera of my OnePlus 3 because it wasn't focusing anymore, after reassembling my phone I noticed it wasn't connecting to the wifi anymore, tried Bluetooth and it was the same problem... I had to be really close for it to connect
Did any of you had any luck solving this problem? Did changing the board in the bottom of the phone not solve it? It seems that's where the WiFi is... Or maybe changing the backplate
Thanks in advance!

i also have same problem , need fix
Anyone found a solution? I had the same problem when I replaced the fingerprint sensor + the battery
I've been without wifi for 4 months now... Any help is appreciated
Hi, guys. I have the same problem. Did anyone find a solution?
I replaced my rear camera and the loudspeaker, at reboot wifi was not working. I noticed that if I'm near the access point network is detected but with very poor signal strength. Thanks.
Hi, maybe I could have found a possible reason to our lack of wifi and bluetooth signal.
Please look at this thread and give me your opinion. Probably your mainboard shows the same problem.
