w850i flashing white screen, even when turned off

[rowilk]

heres a WSOD problem with a twist, the screen on my w850i flashes on and off every few seconds even when its turned off, as soon as i insert the battery it starts doing it. the phone just vibrates briefly when i turn it on and keeps flashing.

When i connect it to the computer it makes the connect and disconnect noise in windows XP, it continues to do this repeatedly as if im connecting and disconnecting the phone rapidly.

Ive installed the drivers for the phone but XS++ wont detect it.

Is anyone able to offer some help or advice for this problem?

Thanks alot


also it will register in xs++ when i press 2 and 5 when plugging into computer but not 'c', any ideas why this might be?
