Verticale flashing white lines on 7000 screen.

Hi Fellow 7000 owners.
A few weeks back my 7000 started/developed a problem with vertical flashing white lines across the screen, most noticeable while out night detecting, the lines are most prominent on start-up and shut-down and also when changing setting values once a particular setting has been selected. There is no sign of the lines on the detect screen.
Have any forum members struck this problem with their 7000's? Thanks in advance for any information on this issue.
Cheers, AUoptimist.

After a few months detector use, one of my detecting buddies copped a screen pixel problem upon startup, which stayed on screen during detector operation, AUoptimist. The problem was explained to Minelab & the detector was sent back, looked into, repaired & returned with new hand-piece/screen. All, free of charge.
Get it looked into.

Cheers Kon.  

Thanks Kon, the vertical lines are most prominent during the middle part of the start-up screens, ie, just before the various menus pop up and the last part of the shut-down screen very prominent lines just before the machine turns off.
I will give ML a call and see what the tech guy has to say.
Cheers, AUoptimist.

Up-date on the flashing vertical lines, The GPZ7000 is heading back to MineLab early in the new year, just glad the problem became obvious at the end of the detecting season.
Cheers, AUoptimist.
