Hi there,

I have an Nokia 446Xpro which sometimes suddenly has no picture at all. Yo
?ll hear the high voltage go away, the front LEDs stay on (both green, so
no standby mode entering); no on-screen menu, brightness and contrast don?t
have any effect. Switching off and on has no effect. After unplugging,
waiting at least 5mins, plugging and switching on the monitor works great.
There?s absolutely no time constant until the picture goes black.

Somebody knows this fault?

Thanks,
Sebastian
