HI Guys, (gals)

I have a 600E and it seems that the backlight has a bad connection.
I can cycle through the display options from the keyboard and as it
changes modes the lighting flashes on but quickly fades to black. It
looks like a loose connection but I have no idea what to do or where
to look for the answer.

IS this a common problem whith these machines? is it fixable? or Do
I have to replace it?

Any help would be apperciated.
