Most ericsson phone with jog wheels have the same issue, i had a k750i before using 800i and i had to deal with it before getting it repaired, a work around i did was to open the unit up, look for the contacts of the wheel, and clean it with a pencil eraser. it may come back in a few months, if in case this did not do, replacing the scroll wheel set and its contacts will be replaced too. best if you go to an ericsson authorized repair center if you want to replace the parts.

You can do this by entering the Service Menu and selecting Format. Here is how to get there:
  1. In flip closed mode: jog-dial up, *, down, down, *, down, * -
  2. In flip open/removed mode: In phone application, jog-dial up, touch *, down, down, *, down, * .

The LG U400, nicknamed the Neo, is a 3G music phone available exclusively on the 3 network. The U400 has an unusual and distinctive slide design. Despite a smart black and silver finish, and cool blue detailing, it's an ugly beast, mainly because of the large jog wheel located off-centre, with call buttons to the side. The jog wheel is very useful, however, enabling control of the music functions when the phone is closed. With a chunky feel and uncompromising looks, this is a phone with a very masculine style

Sony ericsson K 800i

we will approach the problem this way
1) your battery might be the culprit , first charge your battery in a different piece, and then replace ans see.
2) if the above doesnt solve the problem clean the connectors of the battery that shiny golden part of both your battery and mobile piece , with nail p[olish remover or alcohol.
3) last resort now will have to open the piece and check for the on/off switch .
4)lastly software reflashing, but if the piece aint dtecting, need to clean the datacable connectors with nail polish remover or alcohol.

the above should bring your pice to life.
