New lg vu won't wake up after 10-15 at rest. only works again after removing & reinstalling battery & powering up. works as long as you continue to push buttons. . battery full. 5 bars of service. TV symbol on top randomly displays. is this trying to pull in a signal for tv?  I do not have this option. This is the 2nd LG vu phone in a week this has happened. New phone, new battery, same sim card.

I feel your pain brother, I'm on my 4th lg vu cause of the same problem. and the att store doesnt have a answer the just keep replacing it. i just got another one replaced yesterday.

SOURCE: phone shuts off

if you droped the Vu than you could have damaged the insides and that might cause the repeating of it shuting off but a easyer way to get music onto your Vu is to get a Micro SD and get an adaptor for it and put music on that and then plug the SD into your phone its alot easyer and faster than useing the cord

hope this helps

you better check the power switch of your phone, i think, it was shorted or dammaged

SOURCE: LG Vu Sim Card problem

I've dealt with this issue ever since I bought this phone - and would rather throw it across the room and watch it burst into 1,000 pieces than have to see the error pop up again. All I did was cut out about 1-inch by1/4" inch strip from a postcard - or any heavy weight paper. In other words, not cardboard, but not copy paper. More like the weight of a vhs cover box, cereal box, etc. I inserted one end of the strip above the sim card and below the phone shell (over the part of the sim card that's not showing); and folded the rest of the paper strip (might have to tear some off) to be double ply above the part of the sim card that is showing. Put on the cover; you should have to press firmly to get it to fit on and smash the double-ply strip down. Make sure the double ply is only over the sim card, not any over the battery. This worked for me!
