Question about LG Vu CU920 Cellular Phone

Open Question

Lg vu will not charge or turn on.

Phone will not charge or turn on. Took it to the AT&T store where they replaced the battery and it worked for a day. Still wouldn't charge then. Went back to the store and they got it to work. Brought it home and it won't turn on or charge.
What's up with that?

SOURCE: My LG VU CU920 keeps turning off

I had the same problem even after I exchanged the phone for a new one. The problem seems to be related to Mobile TV and the SD memory. When I removed my 2GB SD memory, the problem has not reoccurred. I recently installed a 512MB SD memory chip and so far I have not experienced the problem.

SOURCE: Lg Vu wont charge

First you must determine is it the charger faulty or the phone ? , have you a friend with the same phone if so try her or his battery to see if your phone is ok if so try the charger with your battery and see if it charges if it does get a new charger , if it did not charge or work with your friends battery or charger the sorry it would be cheaper to buy a new phone than try to get it fixed ...
if you haven't got a friend with the same phone have a local electrician check if there is an output from your charger . if there is it may just be the battery try a new one if still no luck it is probably the phone's charger circuit gone pop ,, sorry .. vortash

SOURCE: lg vu won't charge but on a computer

If it is new, take it to the dealer where you got it from and ask for a replacement charger. More than likely that is what is the problem

SOURCE: how do i resolve the error: use genuine battery. power off

A temporary fix to the problem is to put the battery in the freezer for a minute and then put it back in the phone and it will turn on just fine! I had an LGVX8700 and it just randomly started happening one day and my fiance told me to try doing that so i did and sure enough it worked. I had to go to verizon at one point to get a new phone because the one i had got damaged and the tech there used the same battery in my phone for the new one and he thought i was crazy when i told him to put the battery in the freezer but he was in for a surprise when he did what i told him and my phone turned on. It's annoying because you have to do that everytime your phone shuts off but i always made sure i plugged it into the charger before it went completely dead.

It is loose now the charging port may have gotten broken. It happens with the LG VU's.
