My Camera LED isn't working any more .I don't know why,probably just gave way. I found the replacement Sim and memory socket flex online.Do you recall how that flex was connected to the logic board ? a clamp or just a slide in kind of thing .?

I got my phone wet and cleaned the mother board, took apart the phone as described. And it worked. Problem is I have no stereo sound. So no ringer, alarm, or anything. Took apart again, still nothing. The corrosion was only on top side. Not bottom with speaker. Any suggestions...?

In case anyone's interested.. The black and silver cylindrical component that is near the bottom of the phone "behind" the back key is the vibrate motor. I dropped my phone and it stopped vibrating completely. I replaced this and got my vibrate back! I couldn't find the part by itself so I had to buy a broken phone off ebay

Where actually is the wireless internet antenna located on the motherboard? Which piece is it in your diagrams?

Usually when i get a new phone i look around the web for a guide to replace the lc just incase i ever need to...well, after much searching, i never found a guide for the LG Nitro it must just not be as popular a phone as i thought. So i used my own Nitro to make a guide to replacing the LCD screen...
Tools you will need: #00 Phillips screw driver & plastic prying tool (a guitar pic will also suffice)
http://forum.xda-developers.com/atta...1&d=1335128382
The easiest way i found to get the back off of the phone is start at the mouth receiver using a finger nail move around both sides popping the tabs out...then kinda jiggle the top off...

http://forum.xda-developers.com/atta...1&d=1335128382
Remove all 9 screws highlighted by the red "O"
The piece highlighted yellow is a plastic cover you need to remove first best pop the bottom up like you did the back of the phone and slide it down comes off easy goes back hard

http://forum.xda-developers.com/atta...1&d=1335128382
this is wat the piece should look like wen you get it off...

http://forum.xda-developers.com/atta...1&d=1335129363
The area highlighted the yellow/green color is another plastic cover the needs to be removed. I started at the bottom left side of the phone and again wen around it with my thumb nail to pop the tabs...there may come a point you may have to apply a little bit of force to pull the tabs
CAUTION while trying to remove this piece the LDC tries to come up due to a little adhesive holding the piece down you do not want that to bend too much
Also be cautious of the volume and power buttons as they WILL fall out and you WILL lose them (like i did for hours) if you dont mind them..below is wat they look like
http://forum.xda-developers.com/atta...1&d=1335129363

You now will be able to see the control board....Fun Fact there are extra antenna plugins aswell as an extra ribbon plugin....wonder Y?
Next step is to unplug all the ribbon cables highlighted in yellow as well as the wifi antenna, not all the ribbons need to be unplugged just the highlighted
After (not before) you unplug the cables remove the four screws highlighted by the "O"
http://forum.xda-developers.com/atta...1&d=1335129363
The camera (center) and headphone jack (bottom left) can be easily removed
just by pulling them out...below is wat they look like...

http://forum.xda-developers.com/atta...1&d=1335130305
Next removing the Control Board u may have trouble getting it lose from the touch screen around the area pointed to be the orange arrow aswell keep an eye on the touch screen ribbon as it is very flimsy pointed to by the green arrow
http://forum.xda-developers.com/atta...1&d=1335130305

http://forum.xda-developers.com/atta...1&d=1335130305
Now to remove the touch screen to access the LCD...bend back the ight blue highlighted ribbon and seperate the two pieces that are the touch screen and the plastic piece holding the LCD and digitizer
Highlighted in red is a small rubber piece holding the touch screen ribbon down...below is a picture of the peice
http://forum.xda-developers.com/atta...1&d=1335130305
Here is a pic of the touch screen removed...
http://forum.xda-developers.com/atta...1&d=1335130305

CAUTION THE LCD ISNT HELD IN VERY GOOD SO WATCH OUT FOR IT TO FALL OUT OF THE DIGITIZER WHERE ITS HIGHLIGHTED IN YELLOW
http://forum.xda-developers.com/atta...1&d=1335131305

http://forum.xda-developers.com/atta...1&d=1335131305
Highlighted here in yellow is the ribbon to the LCD starting where the connecter is to the ribbon peal off all of the highlighted area
Careful here is where the ribbon is bent so dont peal to fast of it could rip
Remove the black square holding down the ribbon and pull the ribbon through the slot to the side where the LCD is and it should come right out of the digitizer...(I dont have a pic of the one but its pretty obvious at this point wat to do)

I hope this helps somone like me that just couldnt find the answer they were looking for....good day!

nice post
did you noticed something about the wifi antena , because i tried some 2nd hand lu6200 here in vietnam and to pick up weak wifi signal is hard , and my old phones can cope with the weak signal easy , maybe i can try to make some mod to the antenna
