Hey guys,
Last night I capped my sanyo 20ez, invert board, and audio board... Picture is 110% better than before. Fixed some vertical collapse, brightness issue, and light jail bars

But after about an hour of playing these white scanlines show up, then the screen goes grey. Power cycle and video is fine again.
One thing to note, the horizontal position is off, pot turned all the way, and I cannot fill the right side of the screen...
What do you guys thing may be the cause?
