This post is on behalf of my dad who has one of these:
Model: tz vgn-tz37gn/b
Anyway the problem with it is that it won't turn on. When you press the power on button on the side of the device it just flashes but the system doesn't power up. This is true when the charge cable is un plugged and plugged in. When it's plugged in it says that the battery is charging on the front of the device but that's about all it does right now. It was working fine yesterday until this morning.
