[Q] Lg Quantum Non responsive touchscreen

---

Hey so this is my first post ever, and im really sorry if i put it in the wrong place, if so mods can you do me a solid and move it?

Ive looked around the forums and didnt really seem to find anything on my issue, but my Lg quantum's touchscreen locked up on me. It is completely Non-Responsive, i thought maybe i messed something up in the registry so i did a cold boot and now im stuck at the Welcome to your LG LG-C900 windows phone screen and i cant hit anything! Any ideas what could be causing this to happen, and/or how to fix it? Thanks in advance for any help you guys can provide!

when (if) you did your update to 7008, it should have made a restore point for ya. if you hook it back up to zune theres a restore button in the update page. might be worth a shot...

Hey buddy, thanks a lot! Im gonna give it a shot now, im putting it back together as we speak! If i havent updated it could an update maybe fix what was wrong? If that doesnt work, is there anything else we can try to do to fix it? Anybody know a good tutorial for me to take it apart?


***Edit***
Hey so im having trouble putting the phone into emercency download mode, im trying to work from the thread here , http://forum.xda-developers.com/arch.../t-935605.html , and im confused at the (VOL+CAM+PWR) i hold those and nothing happens to enter a download mode.... anybody have any advice?

i read somewhere that for the (VOL+CAM+PWR) to work, your phone must first be off first.

and idk if we are allowed outside links here, but THIS looks like the same link as your just on a diffrent site. maybe some searching on that site might bring up something...

So an update, after much tinkering with the phone I found that to get into emergency download mode you must first:
shut the phone off
slide open the keyboard
hold space then press power
it goes to download mode instantly

Sadly, updating the firmware manually did not bring back my touchscreen =[

Any other advice? Or somewhere i can go to learn to take apart the quantum properly?

Please post in the proper device forum! I will now move your thread. Please remember to look at the stickys up top, and to look at all the device forums before you post.

Did your digitizer go out? I broke mine -_-

Anyone find a guide on how to replace the digitizer?

Did you get the phone from a supplier (e.g. Bell, Sprint, AT&T)? If so, you might be able to contact their Customer Service to talk about repair/replacement...

I does sound like you have a hardware fault -- not something that can be fixed with firmware, etc.

I just took apart my quantum and found an amazing service manual for it if anyone needs it. I had the same thing when I put it back together but I had just unplugged the digitizer and didnt plug it back in. Ill put up a link to the file if anyone needs it. I gotta also say I friggen love this phone. I apparently knocked it off the table one night into a pitcher of Koolaid. It sat there for hours. In the morning I picked it up and poured a glass and there is my quantum at the bottom of the pitcher. I was livid. I just pulled battery out, dried it, gave it an alcohol bath, opened it up and put it in a tupperware container of rice for 24 hours, then used a hairdryer to get any remaining liquid in there dried. Put it all back together and the only thing wrong with it was water in the LCD. Just replaced the LCD so I can see better, (it was only annoying, but perfectly functional). Digressing... SO I found the service manual and even made a youtube video of the basics of taking it apart. Ill post the links in an edit.

The video sux I know but it was only because no one had one up yet, so I had to post it to show what I found out and what troubles I had etc.
