Just started seeing these thin dark horizontal lines on a G07. The lines get more pronounced as the monitor warms up (longer it stays on).

Any ideas what to look at first? HOT going bad?
 
Unfortunately I don't see what you're talking about. How many lines are there? Are they evenly spaced over the screen?

Consider your HOT like a bomb. It doesn't go bad. It goes BOOM.... if the monitor is turning on, your HOT is great.

Since it's a Defender, I'd be more inclined to think you have a gameboard problem than a monitor problem.
 
I've never seen anything like this, it's like you've got doubled-up black retrace lines. Does adjusting the screen voltage affect them in any way?
 
it does look a bit bright. definetly turn down your screen control.

have you capped it and changed the fly?
i would if you have not done so.
the original caps and fly are pretty worn out by now and need to be replaced.

Looks like retrace lines to me, also. Turn down the screen control, then adjust brightness on the neckboard with the individual colour pots.
 
Thanks for all the replies. However the screen appears a little brighter in the pic than it actually is because I had to set the camera with a long exposure to pickup the horizontal lines in the picture. With the naked eye the lines are seen plain as day. Will try adjusting today and let you know the outcome.

I just got the game a month ago and it appears the previous owner re-capped the monitor though I do not know how long ago. The flyback transformer definitely looks like the original however.
 
my defender does the same if its on for more then an hour. it has been capped but not a flyback so I am leaning to the flyback needing to be replaced.
