8 month old vf4 , LCD backlight has gone out a couple of times and refuses to start back up . It normaly goes out as what I assume is a screen saver feature about every 10 minutes or so , on a number of occasions last week it will no light back up at all, no amount of button pushing, reset estop etc will bring it back to life. I have to shut the machine down and reboot to bring it back to life. Its done it twice this week , rather irritating . The monitor is still displaying, I can shine a bright light at it and see the screen but just no back light.
Is this a software issue and how do I resolve? Called HFO on Friday noon

Check setting 199 'backlight timer'
If there is a value in setting 199 then change it to zero.
